Overview
The nutrients contained in a cup of blackberries provide a significant source of vitamins known to improve eye health. The National Eye Institute recommends certain nutrients for macular degeneration, some of which you can get through food sources. This is why the institute developed a vitamin supplement called the age-related eye disease study formula, or the AREDS formula. Some of the nutrients in the formula also are provided by blackberries, but eating blackberries alone will not provide all the nutrients you need for macular degeneration.
AREDS Formulation
The formula designed by the National Eye Institute contains significant amounts of antioxidants to prevent the further degeneration of the eye cells. The formula contains 15 mg of beta-carotene, which is the equivalent to 25,000 international units of vitamin A. The supplement also contains 500 mg of vitamin C, 400 IUs of vitamin E, 80 mg of zinc and 2 mg of copper.

Nutrients in Blackberries
Blackberries contain some of the nutrients provided in the vitamin formula developed for macular degeneration. One cup of blackberries contains 308 IU of vitamin A, 30.2 mg of vitamin C, 1.12 mg of vitamin E, and trace amounts of zinc and copper: 0.76 mg and 0.238 mg, respectively.
Comparing Vitamins
The dietary reference intake, or DRI, is lower than the amount of vitamins in the AREDS formula recommended for macular degeneration. According to the Linus Institute, the daily DRI for vitamin A is 700 to 900 mg, vitamin C 75 to 90 mg, 22 IU of vitamin E, 8 to 11 mg of zinc and 900 micrograms of copper. The lower amounts are recommended for adult females and the upper amounts for adult males. Blackberries contain high sources of vitamins A, C and E, but the National Eye Institute recommends vitamin supplements because you cannot get all of the nutrients you need for macular degeneration from natural foods or a daily multivitamin. As an example, a female would need to eat more than 35 cups of blackberries to get the amount of vitamin A provided in the AREDS formula.
Considerations
While blackberries do contain sources of nutrients that improve eye health, some nutrients work better when taken with other vitamins. In addition, you might require additional vitamins and minerals when you take certain vitamin supplements. A study published in "Archives of Ophthalmology" in 2001 suggests that zinc works better when taken with antioxidant vitamins A, C and E. The AREDS formula also contains copper to prevent copper deficiency, which can occur when taking zinc supplements.

Do Diabetic Diets and Macular Degeneration Disease Conflict?
by: Livingstrong
Multiple health conditions may cause difficulties with dietary choices, since you must avoid certain foods or nutrients with certain conditions or medications. For diabetics, diet plays an important role in blood sugar control. Macular degeneration is a condition that relies on diet for prevention and slowing the progression of the disease. If you have both diabetes and macular degeneration, you should know the nutritional needs of each condition to ensure that you meet all of your dietary requirements.
Diabetes
A healthy diet is important for controlling your blood sugar levels. You should eat lean proteins, such as skinless chicken breasts and fish, as well as healthy fats, such as olive oil. Choose whole-grain breads, cereals and pasta, and eat brown rice instead of white rice. If you use dairy products, eat low fat options and choose skim milk over whole milk. One of the most important dietary choices for diabetics is eating plenty of fruits and vegetables. A diet that consists of a wide variety of health, whole foods will provide you with the nutrients you need, and may also help stabilize your blood sugar.
Macular degeneration is a condition caused by the break down of cells in the macula, an area of tissue located on the retina that lines the back of your eye. The damage to these cells can lead to the loss of your straight-ahead vision. Treatment options do not typically improve vision, and this means that prevention plays the most important role in macular degeneration. The National Eye Institute has determined that nutrients such as zinc, vitamin E, vitamin C and beta carotene may help reduce the risk of this devastating condition by 25 percent.
No Conflict
The diets needed for diabetes control and macular degeneration prevention do not conflict. In fact, preventing macular degeneration relies heavily on the nutrition you will find in the healthy fruits and vegetables that make up part of a healthy diabetic diet. For example, a salad made with a variety of vegetables and dark, leafy greens will provide nutrients for macular degeneration prevention. This also makes a healthy diabetic meal, particularly if you add grilled chicken breast or salmon. If you select salmon, this will also provide omega-3 fatty acids, another nutrient that may help prevent macular degeneration.
Considerations
Before making dietary changes, talk with your doctor about your nutritional needs. If you take certain medications, such as blood thinners, you may need to avoid large amounts of certain nutrients. Your doctor will help you determine a nutrition plan specific to your needs.

Nutrients From Eggs
by admin
Won O. Song, PhD, MPH, RD, and Jean M. Kerver, MS, RD
Food and Nutrition Database Research Center, Department of Food Science and Human Nutrition, Michigan State University, East Lansing, Michigan E-mail: song@pilot.msu.edu
Objectives: The main purposes of this study were (1) to assess the nutritional significance of eggs in the American diet and (2) to estimate the degree of association between egg consumption and serum cholesterol concentration.
Methods: Data from the most recent National Health and Nutritional Examination Survey (NHANES III, 1988-94) were utilized to compare the nutritional quality indicators of diets that contained eggs (USDA food grouping system) with those that did not. Nutrient intake (from 24-hour dietary recall), egg intake (from food frequency questionnaire), sociodemographic data and blood cholesterol levels of subjects who met inclusion criteria (n=27,378) were grouped according to the occurrence and frequency of egg consumption and were analyzed using SUDAAN.
Results: Daily nutrient intake of egg consumers (EC) was significantly greater than that of non consumers (NC) for all nutrients studied (except dietary fiber and vitamin B6). Eggs contributed < 10% of daily intake of energy and vitamin B6, 10% to 20% of folate and total, saturated and polyunsaturated fat, and 20% to 30% of vitamins A, E and B12 in EC. Compared to EC, NC had higher rates of inadequate intake (defined by Estimated Average Requirements (EAR) or < 70% Recommended Dietary Allowance (RDA)) for vitamin B12 (10% vs. 21%), vitamin A (16% vs. 21%), vitamin E (14% vs. 22%) and vitamin C (15% vs. 20%). After adjusting for demographic (age, gender and ethnicity) and lifestyle (smoking and physical activity) variables, dietary cholesterol was not related to serum cholesterol concentration. People who reported eating 4 eggs/wk had a significantly lower mean serum cholesterol concentration than those who reported eating 1egg/wk (193 mg/dL vs. 197 mg/dL, p < 0.01). More frequent egg consumption was negatively associated with serum cholesterol concentration (beta = -6.45, p < 0.01).
Conclusions: In this cross-sectional and population-based study, egg consumption made important nutritional contributions to the American diet and was not associated with high serum cholesterol concentrations.

Why You Need Vitamin D
By: Administration
Professionals who understand nutrition have proclaimed that Vitamin D deficiency is epidemic! But what is Vitamin D? It is a group of fat soluable vitamins. The two major forms of Vitamin D are D-2 (also known as ergocalciferol if you are into biology) and D-3 (cholecalciferol). D-2 is synthesized by plants. D-3 is synthesized by humans in the skin when exposed to ultraviolet-b rays of sunlight.
Vitamin D is essential for your body! For more than a century, scientists believed it played a vital role in bone health. It functions to maintain normal blood levels of calcium and phosphorus. It promotes calcium absorption in the gut. This is important because it enables healthy mineralization of bones and healthy bone growth. Humans cannot digest calcium without Vitamin D-3.
Does Vitamin D make you smarter? Some researchers say “yes!” 1.
But Vitamin D does so much more! It also assists your immune system. It does this through cellar differentiation which leads to decreased proliferation. Stay with me here, this is really pretty simple. Proliferation in general is good as it helps wounds heal. But uncontrolled proliferation of cells may lead to cancer. Vitamin D inhibits the bad proliferation and stimulates differentiation.
Classical Vitamin D deficiencies include adults who complain of dull and achy musculoskeletal pain. Such pain is usually unresponsive to both pharmaceutical and manual treatments. Also among children deprived of Vitamin D is the classical case of rickets.
But did you know Vitamin D deficiency has been linked to the following conditions?
High blood pressure
Fibromyalgia
Diabetes
Multiple sclerosis
Rheumatoid arthritis
An increased risk of pre-eclampsia and insulin resistance during pregnancy
Increased risk of early age-related macular degeneration. 2-5
Researchers who have no financial interest in supplements are pleading with people to get more Vitamin D. 6. So how do you get Vitamin D? Getting 10-20 minutes of sunlight helps. I heard one professional suggest (tongue-in-cheek) that people get their D by sunning nude for 15-20 minutes. No thanks J. Experts argue that sunlight does not give you enough D and many people are concerned about skin cancer. Besides, as we age, we are less equipped to produce sufficient quantities of D. If you think tanning beds are the answer, sorry. Tanning beds do not provide D-3.
Most foods do not have adequate D. Consequently it is supplemented with D. Unfortunately manufacturers keep their costs down by using the less expensive form, synthetic D-2. This will never work because our bodies will never absorb the synthetic as well as a natural vitamin and we need D-3. If you want to eat your D try cold water fish. Wild salmon, mackerel, and sardines are good. Egg yolks are also a source. Unfortunately I also hear nutritionists say to avoid the fish because of heavy metals and avoid egg yolks because of the fat.
Personally I recommend GBG’s 10-In-One Liquid Multi Formula. It has an excellent source of D-3. Your body will absorb it better than any synthetic vitamin made in a laboratory and it is a complete phytonutreint/antioxidant blend that tastes good.

Vision Nutrients cross references to specific diseases
by:Natural Eye Care
Here is an outline of vision nutrients with cross references to specific diseases and recommended products.
Amino Acids
Cysteine – is important for a healthy retina. Taken as N-acetyl-cysteine (NAC), it increases production of gluatathione, one of the most important antioxidants in the eye.
* Food Sources: Eggs.
* Other sources: Supplements
* Recommended Dose: 500-1000 mg in the form of N-acetyl cysteine daily.
* Eye Conditions: Macular Degeneration , Glaucoma, Cataracts

* Eye Conditions: Macular Degeneration , Glaucoma
* Recommended Product(s): Advanced Eye & Vision Support Formula, Liquid Taurine
Bioflavonoids
Bioflavonoids are neither vitamins or minerals, but plant pigments that protect the eyes from sunlight damage, and are powerful antioxidants that my enhance blood flow to the retina while fighting free radical damage.
Quercitin, Rutin - quercitin has properties similar to melanin, and protects the eye from damage by solar radiation and works synergistically with taurine and vitamin E. Rutin has been shown to reduce leakage from small blood vessels in the retina. It is valuable in fighting free radicals.
* Food Sources: Cherries, white grapefruit, apples, pears, grapes, cranberries, red onions, green cabbage, spinach, kale, onions, garlic.
* Other sources: Supplements
* Recommended Dose: 1000 mg of quercetin daily, 300 mg rutin daily.

* Recommended Products: Optic Nerve Formula , Advanced Eye & Vision Support Formula
Carotenoids
Carotenoids are organic pigments that are naturally occurring in plants and some other photosynthetic organisms like algae, some types of fungus and some bacteria. There are over 600 known carotenoids; they are split into two classes, xanthophylls and carotenes. They are potent antioxidants and play a protective role in preventing many eye conditions.
Bilberry – is the European version of the blueberry, and has been called the vision herb for its powerful effect on all types visual disorders.
* Food Sources: Huckleberry
* Recommended Dose: 240-300 mg daily.
* Eye Conditions: Poor Night Vision, Glaucoma, Myopia , Macular Degeneration , Diabetic Retinopathy , Cataracts , Computer Eye Syndrome

* Recommended Dose: 3 mg daily for prevention, and up to 20 mg per day therapeutically.
* Eye Conditions: Macular Degeneration and other macula disorders
Essential Fatty Acids (EFA’s)
Omega 3 Fatty Acids - fats are essential for nerve conduction in the retina and to reduce cholesterol.
* Food Sources: Cold water fish (including salmon, tuna, mackerel, halibut), flax seed oil, black current oil, walnuts and walnut oils, dark leafy vegetables, eggs (from free range chickens preferred), spices (including mustard, fennel, cumin and Fenugreek).
* Recommended Dose: 1500 mg daily
* Eye Conditions: Glaucoma, Macular Degeneration
* Recommended Products: Carlson's Fish Oil, BioTears
* Notes: Any time oils are increased in the diet, for example by eating nuts or using lots of cooking oils, be sure to increase intake of vitamins A, B3, B6, C, E and minerals zinc, selenium, and manganese for proper absorption.
Omega-6 Fatty Acids – are important to protect cells from degenerative changes and to reduce inflammation throughout the body.
* Food Sources: Human mother’s milk, evening primrose, borage and black currant oils.
* Recommended Dose: 1500 mg daily
* Eye Conditions: Glaucoma, Macular Degeneration

* Other Sources: Supplements
* Recommended Dose: 200 mcg daily.
* Eye Conditions: Glaucoma, Macular Degeneration , Diabetic Retinopathy
* Recommended Product: Advanced Eye & Vision Support Formula
* Note: Chromium reduces the blood sugar levels of diabetics, and may require the patient to adjust the insulin dose accordingly.
Magnesium – is a mineral that relaxes smooth muscles and helps prevent muscle spasms. Smooth muscles are what regulate the outflow of aqueous humor from the inner eye.
* Food Sources: Almonds, wheat germ, green leafy vegetables.
* Recommended Dose: 500 mg daily.
* Eye Conditions: Glaucoma, Macular Degeneration, Diabetic Retinopathy, Blepharospasm (twitching of the eyelids), Keratoconus
* Other Conditions: Also good for migraines
* Recommended Products: Optic Nerve Formula , Advanced Eye & Vision Support Formula, BioTears
* Note: If you are taking antibiotics, do not take magnesium because it interferes with the antibiotics effectiveness.
Selenium – makes sure that glutathione is doing its job. It does this so well that patients with macular degeneration have reported improved vision after taking selenium and vitamin E.
* Food Sources: Garlic, onions, broccoli, cabbage, brown rice, eggs, shrimp, sunflower seeds, tuna, chicken, brazil nuts, wheat.
* Other Sources: Supplements
* Recommended Dose: 200 mcg daily.

Zinc – has been shown to stabilize and even improve vision in people with macular degeneration.
* Food Sources: Barley, wheat, chicken, crab, oysters, lamb, beef, turkey.
* Other Sources: Supplements
* Recommended Dose: 30 mg daily.
* Eye Conditions: Macular Degeneration , Glaucoma, Cataracts, , Poor Night Vision, Floaters
* Recommended Product: Advanced Eye & Vision Support Formula
* Note: Zinc deficiencies can result from the following:
1. excessive sweating,
2. high fiber diets can bind zinc and prevent its absorption,
3. phosphates in soda interfere with zinc,
4. coffee drinking can produce zinc deficiency.
* Zinc supplement should not be taken with copper, iron, calcium or fiber (which bind the zinc and make it unusable). Copper is inhibited by zinc, so if zinc supplements are used, 2 mg of copper should be taken daily.
Other Nutrients
Alpha Lipoic Acid plays a crucial role in the mitochondria, the energy-producing structures in cells, and it helps deactivate an unusually wide array of cell-damaging free radicals. This is an essential nutrient for the eyes. A recent research study suggested that the alpha-R form is the most bioavailable.
* Food Sources: Good food sources of alpha lipoic acid include spinach, broccoli, beef, yeast (particularly Brewer's yeast), and certain organ meats (such as the kidney and heart).
* Other Sources: Supplements
* Recommended Dose: 300 mg per day or 150 mg per day of Alpha-R Lipoic Acid, or more as prescribed by your health care professional.
* Recommended Product: Alpha Lipoic Acid
* Eye Conditions: Glaucoma, Macular Degeneration , Diabetic Retinopathy , Cataracts
Garlic – helps prevent blood clots from forming in the small blood vessels of the retina.
* Food Sources: Fresh garlic cloves
* Other Sources: Supplements
* Recommended Dose: 1000 mg of garlic powder, 20 mg of garlic oil, 3 cloves per day.
* Eye Conditions: Glaucoma, Macular Degeneration , Diabetic Retinopathy , Cataracts
* Recommended Product: Garlic Tablets
* Note: Garlic contains cysteine, methione, and glutathione. It reduces cholesterol, thins the blood without the side effects of aspirin, reduces blood pressure, and is used as a natural antibiotic.
Coenzyme Q10 (also called CoQ10) helps cells breakdown food into energy, and improves heart function and overall blood circulation.
* Food Sources: The best sources of CoQ10 are animal muscle tissues, but many people prefer not to eat this type of food. It is also found in vegetables, particularly spinach and broccoli, but it is easily destroyed in the cooking process.
* Other Sources: Supplements
* Recommended Dose: 30 mg per day, or more as prescribed by your health care professional.
* Eye Conditions: Glaucoma, Macular Degeneration , Diabetic Retinopathy , Cataracts
* Recommended Product: Coenzyme Q10
Vitamins
Vitamin A – we usually recommend taking vitamin A in the form of beta-carotene, which converts to vitamin A with a small amount of fat in the diet.
o Food Sources: Yellow and orange vegetables, including yams, carrots and sweet potatoes, asparagus, spinach, butternut squash, kale, bok choy, mangoes, cataloupe, apricots.
o Other Sources: Supplements
o Recommended Dose: Approximately 15,000 to 25,000 I.U. of beta-carotene daily.
o Eye Conditions: Macular Degeneration , Glaucoma, Cataracts, Dry Eyes
o Recommended Products: Advanced Eye & Vision Support Formula, BioTears, Vitamin A
o Note: If you have a low thyroid problem, diabetes or problems with fat absorption, beta-carotene may have difficulty converting to vitamin A.
Vitamin B2 (Riboflavin) – aids in the reception of light by the retina, and is necessary for glutathione production.
+ Food Sources: Brewer’s yeast, beans, wheat germ, whole grains, almonds.
+ Other Sources: Supplements
+ Recommended Dose: 10 mg daily.
+ Eye Conditions: Macular Degeneration , Glaucoma, Cataracts, Dry Eyes
+ Recommended Product(s): Advanced Eye & Vision Support Formula, Vitamin B2 (Riboflavin
+ Note: If deficient in vitamin B2, it may help with the following conditions: 1) soreness around the eyes, 2) eyes tiring easily, 3) sensitivity to light, 4) dry eyes, 5) cataracts, 6) conjuntivitus, 7) macular degeneration, 8) styes.
Folic Acid - also called folacin and folate, is a water soluble B-vitamin that helps build healthy cells. "Water soluble" means it does not stay in your body for very long, so you need to take it every day to help prevent neural tube defects. During periods of rapid growth, such as pregnancy and fetal development, the body's requirement for this vitamin increases.
+ Food Sources: Green leafy vegetables, and broccoli.
+ Other Sources: Supplements
+ Recommended Dose: 400 mcg daily.
+ Eye Conditions: Cataracts
+ Recommended Product(s): Advanced Eye & Vision Support Formula, Folic Acid
+ Notes: Should be taken with vitamin B12 and Zinc.
Vitamin B6 (Pyridoxine) – found to be deficient in almost all persons with macular degeneration. B6 aids in the proper absorption of magnesium, and has a diuretic effect which helps decrease eye pressure.
+ Food Sources: Avocados, bananas, brewer’s yeast, carrots, brown rice, wheat germ, sunflower seeds.
+ Other Sources: Supplements
+ Recommended Dose: 50 mg daily.
+ Eye Conditions: Dry Eyes

2. high fiber diets can bind zinc and prevent its absorption,
3. phosphates in soda interfere with zinc,
4. coffee drinking can produce zinc deficiency.
* Zinc supplement should not be taken with copper, iron, calcium or fiber (which bind the zinc and make it unusable). Copper is inhibited by zinc, so if zinc supplements are used, 2 mg of copper should be taken daily.
Other Nutrients
Alpha Lipoic Acid plays a crucial role in the mitochondria, the energy-producing structures in cells, and it helps deactivate an unusually wide array of cell-damaging free radicals. This is an essential nutrient for the eyes. A recent research study suggested that the alpha-R form is the most bioavailable.
* Food Sources: Good food sources of alpha lipoic acid include spinach, broccoli, beef, yeast (particularly Brewer's yeast), and certain organ meats (such as the kidney and heart).

Ophthalmologists focus on preserving,restoring and enhancing vision in aging patients
by Richard L. Lindstrom, MD
Aging is one risk factor for disease and degeneration that no one can avoid. As all of us over the age of 60 know, the only good thing about aging is that it is superior to the alternative. It is telling that in the U.S., those over the age of 65 years consume 10 times the eye care as those under the age of 65 years.
The challenge for all seniors is to age gracefully, remaining as healthy, wealthy and wise as possible, allowing a high-quality, joyous life. It is part of our duty as physicians to assist our patients in meeting the challenges of aging as best possible. This challenge includes helping them preserve their vision, restoring visual function when treatable diseases are present and, in many cases, enhancing their visual function by, for example, reducing their dependence on glasses when desired.
Preservation of vision includes diagnosing age-related eye disease in a timely fashion and treating patients appropriately. The most common age-related diseases such as age-related macular degeneration, diabetic retinopathy, retinal vein occlusion, cataract, glaucoma and ocular surface disease are all best managed when diagnosed early and treated as indicated. We are all well-trained and experienced in the this type of restorative medical care.
On the other hand, counseling patients in preventive medical care through proper diet and lifestyle habits was not taught in my medical training, which began some 40 years ago. When I began my medical training in 1969, the significant impact that nutrition and behavioral choices can have on health and quality of life were both less well-understood and, to be direct, neglected in our formal educational process. Today we know that lifestyle choices can have a significant impact on our patients’, and our own, health and quality of life. Clear risk factors include smoking, a poor diet high in saturated fats, inadequate fruit and vegetable ingestion, lack of exercise and improper eye protection when performing dangerous activities, such as pounding a nail. It is important for us all to be aware of these factors and share this knowledge with our patients.
I am an advocate of nutritional supplements and encourage for many patients antioxidant and multiple vitamin supplements as well as omega-3 fatty acids. I take these myself as well as a daily dose of aspirin. Avoidance of smoking is critical. If one enjoys the occasional alcoholic drink, red wine seems the best choice with its high content of the antioxidant resveratrol — ideally never more than two glasses in a given day. Fish is to be encouraged frequently in place of meat. My internist’s recommendation is fruit for breakfast, salad for lunch, and fish or white meat for dinner with lots of green vegetables. In addition, exercise is critical. For most in their senior years, walking is the best therapy, along with light weight training. In addition, the impact of companionship on health and quality of life is well-established. Isolation often leads to depression, and it is important for all physicians to look for and offer referral to the untreated depressed patient.
In regards to vision restoration, the most common cause of visual disability in advanced countries, AMD, can in many cases be mitigated by referral to a specialist in low-vision aids. I ask every new patient I see with significant visual disability whether they have seen a low-vision specialist, and sadly, I would estimate that only about 10% have been previously evaluated. In addition, well more than 50% of senior patients with a visual disability also suffer from an untreated hearing disability. We now screen for this in our practice as well and offer treatment. This is an area where we as a profession can do better.
Of course, most rewarding is the restoration of vision, and the miracle of modern cataract surgery remains one of the most satisfying operations in all of medicine to perform. For many patients, we can not only restore good vision, but in many cases enhance visual performance and quality of life through the utilization of refractive cataract surgery customized to the individual patient’s lifestyle goals.
While the rewards of visual restoration remain at the core of our practice as ophthalmologists, it is important that we do not neglect our duty to preserve vision as well. I also believe it is now appropriate for every cataract surgeon to learn and practice the skills required for refractive cataract surgery, which provides the most common opportunity today for visual function enhancement in the senior patient. As always, the demand for lifelong learning and surgical skill advancement remains a challenge, but the positive impact on our senior patients’ quality of life is well worth the effort.

Nutrition and the Eye
Article submitted By Dr. Klair
Aging is a mystery, and everyone does it in their own way. Some people retain clear vision into old age, but most people, even those who are otherwise healthy, develop cataract, and some suffer macular degeneration. Nutrition plays an important role in the long term health of the eye.
The eye is subject to a lifetime barrage of light energy, which includes the white light of vision as well as the higher energy (and more damaging) ultra-violet radiation. The natural lens inside the eye absorbs much of this UV radiation and is subject to cumulative oxidative damage. Vitamin C, or ascorbic acid, is present in high concentration in the aqueous humor of the eye and is believed essential in the repair of this damage. Vitamin C is widely available in citrus fruits and beverages, as well as tomatoes and most acidic fruits. Vitamin C is not stored in the human body and so must be consumed every day. If a person doesn't eat vitamin C rich foods, then they should supplement with 500 milligrams daily. In addition to the health of the eye, vitamin C is critical to the immune system, gums, and skin.
The macula, or central vision area of the retina, has complex pigments that constantly recycle and restore the retina after exposure to light. It has long been known that beta-carotene is essential to this process. Most people know that eating carrots, a rich source of beta-carotene, is good for vision. Vitamin A is supplemented in milk, and is also present in some animal products, especially liver. Humans store vitamin A in their liver and overdosing is possible, therefore the preferred supplement is beta carotene.
Recently it has been discovered that other carotinoid pigments, called lutein and zeaxanthine, are essential to the health of the macula. These are found in carrots but are more abundant in the dark green leafy vegetables, like collard greens, spinach, and kale. Yellow fruits like squash and pumpkin are also a good source. These pigments are concentrated in the macula and play a critical role in the function and restoration of the retina.
Unfortunately, as some people age the macula deteriorates. Age-related macula degeneration (AMD) is the leading cause of new blindness in Americans over the age of 65. The risk is strongly age dependent and by age 75 there is a 5% incidence of the disease. There are two forms, "wet" and "dry," with the wet type being far more devastating to vision. Both types usually begin with the appearance of "drusen" in the macula. These usually appear in the 5th-6th decade of life and are detected by ophthalmologic examination. The American Medical Assoc. recommends screening exams every 2-4 years for ages 40-64, and then annually after age 65.
After years of anecdotal and epidemiologic evidence in favor of dietary pigments for AMD, the Age-Related Eye Disease Study, released in November of 2001, definitively supports the role for dietary supplements in macular degeneration. The study found that patients with macular degeneration who took 80 mg of zinc, 500 mg of vitamin C, 15 mg of beta carotene, and 400 IU of vitamin E daily did better than those who took placebo or other combinations over a three year follow-up.
Eat a broad variety of foods over the course of a lifetime to maintain healthy eyes. Consult an ophthalmologist for use of dietary supplements.

Good Nutrition For the Eyes goes beyond CARROTS
Diana Shechtman, OD, FAAO
Jeffry Gerson, OD, FAAO
Age related macular degeneration (AMD) is the most common cause of vision loss among the elderly. Although we do not have a cure, studies like AREDS (Age Related Eye Disease Study), have shown that nutritional supplementations can reduce the progression of the disease. Yet, as the word indicates, supplementation should be used to enhance an individual’s diet not to substitute it. The best source of nutrients comes from dietary intake and supplementation should be secondary to food modifications.
There are an array of nutrients that have been shown to protect the eye from various degenerative diseases like AMD. Examples include but are not limited to fish, leafy green vegetables, nuts, blueberries and low glycemic foods. It is important to note that changes in a diet should be discussed with your physician to prevent any adverse effects. For example, high levels of vitamin K (found in leafy greens) may intensify the effects of blood thinning medications.
Eat fish
Fish, particularly cold-water fish like sardines, tuna and salmon are a wonderful source of omega 3. Eating two or more serving per week may reduce the risk of progression of AMD.
Make your diet colorful
A variety of yellow, orange, green and red fruits and vegetables can provide a good source of carotenoids. Carotenoids such as lutein and zeaxanthin comprise the macular pigment (a filter in the back of the eye), protecting the eye against damage from UV. Good sources of lutein and zeaxanthin include leafy greens (spinach, kale and collard greens), blueberries, pumpkin, melon, red bell peppers, corn and even eggs.
Milk is not just for bones
Dairy products, like yogurt, are a good source of vitamin D. Vitamin D has anti-inflammatory benefits that are beneficial against a number of diseases in addition to AMD. Sensible UV exposure is required to synthesize vitamin D.
Go exotic
Antioxidants may be found in a number of exotic foods. Such antioxidants may include green tea & goji berries, which have a Chinese origin. Indian food, known for its curry spice, have antioxidants and anti-inflammatory properties. The French are known for their love of wine, which contains resveratrol, having some anti-oxidant properties, as well as cardio-protective benefits.
Supplementation
Although it is preferable to get vitamins and minerals from food, it may be difficult to obtain the high doses needed from diet alone. These particular supplements are not one-size fits all. Although some patients may require nutritional supplementation, not everybody needs an AREDS style supplement and not all individuals should take it. Furthermore, mega-doses of vitamins may be contraindicated and/or harmful in particular cases. More is not always better and mega-doses may be associated with adverse affects. The proper recommendation may depend on age, gender, systemic health, social behavior, as well as current supplements and medications one is taking. Any ocular vitamin supplementation should be discussed with your eye care provider.
In addition to a good diet and possible nutritional supplementation, lifestyle changes are beneficial in decreasing the prevalence and progression of AMD. These include smoking cessation, controlling blood pressure, exercising, maintaining a proper body mass index (BMI), avoiding processed foods, and limiting foods that have a high glycemic index (such as processed foods).
In absence of health related issues or contraindications, addition of various vitamins, minerals, and herbs through a well-balanced diet may play a key role in helping in the fight against AMD. As always, getting a regular eye exam is still a must.

Examples include but are not limited to fish, leafy green vegetables, nuts, blueberries and low glycemic foods. It is important to note that changes in a diet should be discussed with your physician to prevent any adverse effects. For example, high levels of vitamin K (found in leafy greens) may intensify the effects of blood thinning medications.
Eat fish
Fish, particularly cold-water fish like sardines, tuna and salmon are a wonderful source of omega 3. Eating two or more serving per week may reduce the risk of progression of AMD.
Make your diet colorful
A variety of yellow, orange, green and red fruits and vegetables can provide a good source of carotenoids. Carotenoids such as lutein and zeaxanthin comprise the macular pigment (a filter in the back of the eye), protecting the eye against damage from UV. Good sources of lutein and zeaxanthin include leafy greens (spinach, kale and collard greens), blueberries, pumpkin, melon, red bell peppers, corn and even eggs.
Milk is not just for bones
Dairy products, like yogurt, are a good source of vitamin D. Vitamin D has anti-inflammatory benefits that are beneficial against a number of diseases in addition to AMD. Sensible UV exposure is required to synthesize vitamin D.
Go exotic
Antioxidants may be found in a number of exotic foods. Such antioxidants may include green tea & goji berries, which have a Chinese origin. Indian food, known for its curry spice, have antioxidants and anti-inflammatory properties. The French are known for their love of wine, which contains resveratrol, having some anti-oxidant properties, as well as cardio-protective benefits.
Supplementation
Although it is preferable to get vitamins and minerals from food, it may be difficult to obtain the high doses needed from diet alone. These particular supplements are not one-size fits all. Although some patients may require nutritional supplementation, not everybody needs an AREDS style supplement and not all individuals should take it. Furthermore, mega-doses of vitamins may be contraindicated and/or harmful in particular cases. More is not always better and mega-doses may be associated with adverse affects. The proper recommendation may depend on age, gender, systemic health, social behavior, as well as current supplements and medications one is taking. Any ocular vitamin supplementation should be discussed with your eye care provider.
In addition to a good diet and possible nutritional supplementation, lifestyle changes are beneficial in decreasing the prevalence and progression of AMD. These include smoking cessation, controlling blood pressure, exercising, maintaining a proper body mass index (BMI), avoiding processed foods, and limiting foods that have a high glycemic index (such as processed foods).
In absence of health related issues or contraindications, addition of various vitamins, minerals, and herbs through a well-balanced diet may play a key role in helping in the fight against AMD. As always, getting a regular eye exam is still a must.

Sweet Potatoes VS White Potatoes for Macular Degeneration
Both types of potato are a nutritious whole food choice, especially if they are not fried or covered in marshmallows. However, the sweet potato does have a nutritional edge, making it one of the best food choices around, especially this time of year.
Before we talk about sweet potatoes, let's clarify the difference between the sweet potato and the yam. From what I've read, the true yam is found in Africa and is supposedly a rare item in our supermarkets. What we call a yam is really a dark-skinned variety of sweet potato with deep orange flesh. Then there's the lighter-skinned sweet potato that's creamy yellow inside. As a matter of fact, sweet potatoes come in lots of colorful varieties that range from red to deep purple. Look for these the next time you are grocery shopping.
Basically, sweet potatoes and white potatoes are a rich source of vitamins and minerals. Both are similar in calories and lots of other good things like vitamins C and B6 and the minerals potassium, copper, iron and manganese. Both have a bit of protein, and are fat- and cholesterol-free. However, sweet potatoes take the lead when it comes to fiber, vitamin A and antioxidant potential, making them the nutritional winner.
The nutritional benefits of sweet potatoes were a topic in the Tufts University Health and Nutrition Letter (September 2010). What stands out in this report is that the ability of sweet potatoes to satisfy our vitamin A requirements is indeed impressive. The orange color of sweet potatoes indicates that it is rich in the family of plant pigments called carotenoids. One of these, beta-carotene, is converted to active vitamin A in the body. Vitamin A is essential and functions in roles as diverse as enhancing immune function and maintaining eye health. One cup of sweet potato supplies enough beta-carotene to meet 769 percent of the daily value of vitamin A.
Speaking of eye health, lutein is another carotenoid that is found in sweet potatoes and has been associated with protection against age-related macular degeneration. Remember the purple varieties of sweet potato that I mentioned? If you give those a try, you will get even more healthy plant pigments called anthocyanins, which have beneficial antioxidant potential and may be linked to the prevention of a number of diseases.
Sweet potatoes are the perfect food for health and weight control. They tend to be large, so look for small ones and stick to one serving (about the size of a computer mouse). Just bake them right in the skin and season with herbs and spices. If you are watching your weight, the high fiber content will help you feel full and help balance your blood sugar.
If you're among those people who don't eat sweet potatoes because you avoid carbohydrates, that's too bad because you are missing something delicious and so good for you. This fact may change your mind: In 1920, the average American ate an average of 30 pounds of sweet potatoes a year. Today, that number is about 4 pounds. Obesity wasn't a problem 90 years ago. Maybe we should learn something from the way our ancestors ate?

A Recipe for Healthy Eyes
By Larry Oz
Age-related macular deterioration affects the part of the eye responsible for central vision, leading to progressive visual loss and doing every day tasks like recognizing faces, reading, driving and doing detailed work difficult. You are more likely to develop the disease in case you have a family member with this condition, are a smoker, have light colored eyes, are older, are female, or have heart disease. The antioxidant nutrients vitamin C, beta-carotene, zinc, lutein, and vitamin E hold promise for halting the progression of early macular degeneration.
A healthy eating habits could be the most important aspect in building, supporting, maintaining, and also improving vision. Although there is no single diet that is perfect for everyone, specialists agree with the fact that a healthy diet high in vegetables is essential for eye wellness. Choose to help make each meal an opportunity for enjoying more vegetables (preferably organic). Steam, stir fry, or simply eat them raw.
In a perfect world, we would get all of our vitamins from food. On the other hand, advanced farming methods and the depletion of nutrients in soil often results in fruit and vegetables having drastically less minerals and vitamins than they used to, when everything was 'organic'. Foods sold and labeled as organic nowadays have a tendency to have more iron,vitamin C, phosphorus and magnesium and less of the harmful nitrates and other residues from pesticides.
However, not everybody has all set access to organic food, or the money to buy it for the whole family. Hence, vitamin supplements are a great choice to help us get our missing nutrients.
Here is a list of the top 6 phytonutrients ,vitamins and herbs to help alleviate the problem of dry eyes, sore and sustain good vision:
1. Bilberry - is a herb used for both gastrointestinal and eye health. The productive ingredients are called anthocyanosides, which are a type of flavanoid. Anthocyanosides are antioxidants that help improve the flow of blood through the capillaries in eyes. They help eyes adjust quickly to variations in light, and enhance sharpness of vision.
Bilberry has also been presented to be helpful in stopping the development of cataracts when consumed with vitamin E. It is also used to treat diabetic retinopathy, and macular weakening.
2. Vitamin A - Vitamin A is important for good night vision, and may perform a role in stopping cataracts.
3. Grapeseed - Grapeseed is great for the peripheral circulation in our eyes. It also strengthens the capillaries.
4. Eyebright - Eyebright makes a great eye home solution. Steep it in hot water to let the herb infuse, then get rid of the herb and cool the excess liquid. You could place it in the freezer to cool it down easily if you don't have any infused eyebright on hand in the fridge. Once its cool, use it as an eye bath, or a compress. It is great for sore eyes, and has an anti-inflammatory and soothing action.
5. Omega 3 Fatty Acids - Study from Harvard Medical school has found that taking omega 3 oils minimizes the possibility of getting dry eyes. Try taking 3 to 6 grams of a great quality fish oil supplement daily. Researches showed that eating more long chain omega-3 fatty acids was associated with a drastically lower risk of macular weakening amongst people with a lower-than-average consumption of linoleic acid (an omega-6 found primarily in nut and seed oils). Those who ate one to two servings of nuts each week lowered their macular degeneration risk by 35%.
6. Lutein - Lutein is one illustration of a kind of plant nutrient known as carotenoids. Better known examples add beta carotene and alpha carotene. Carotenoids are liable for giving fruit and vegetables their unique colors, and the brightness of a fruit or vegetable is a good sign of how much carotenoids it has in it. Those with a rich color have a higher concentration.
Lutein, beta, and alpha carotene are converted by the body into vitamin A. And lutein is discovered in very high concentrations in the macula of the eye. Lutein is used to help prevent macular degeneration, which is a big problem for people over 40 years of age. Macular degeneration can lead to blindness. Lutein is thought to work as an antioxidant in this capacity.
Other solutions for dry eyes add soaking chamomile tea bags and putting them on both eyes when they're cool. Chamomile helps reduce redness and swelling around the eye. Iced milk can also be used on a shrink for sore eyes. Soak cotton wool or gauze pads with very cold milk (the coolness helps narrow blood vessels), and the fat in milk is very soothing for dry skin.
Get a lot of dark, green leafy vegetables like spinach, kale, collards and chard in your body. Beyond dark greens, go for colored vegetables, including carrots (orange), squash (yellow), beets (red), and red cabbage (purple). Colors indicate phytonutrients, numerous of which are antioxidants and eye-specific nutrients in a position of supplying super nutrition for your eyes. Fruits can help vision, too. Select dark fruits that are high in antioxidants like blueberries and blackberries, as well as dried fruits like raisins and prunes.
Drink carrot juice and fresh organic vegetable juices:
You likely have heard that carrot juice is great for the eyes. Carrot juice works extremely well for this purpose, partly by supplying large amounts of provitamin-A beta-carotene. Get a quality juicer and make at least 16 oz of juice every day. While you are making carrot juice why not add some spinach leaves, beets, celery stalks, parsley greens, or cucumber pieces into the mix?
Fresh vegetable juices truly are the #1 way to improve vision. After my 5 day juice fast my vision improved so much that I was able to stop wearing glasses and used just reading glasses sometimes.
Superfoods for stronger vision:
For boosting core nutrition that helps superb vision, the best foods are superfoods. Superfoods add goji berries, chlorella, spirulina, nutritional yeast, chia seeds, and other foods. Superfoods provide greater quantities of nutrients than are typically found in foods. For example, chlorella provides a large amount of chlorophyll, but also offers essential fats, nucleic acids (DNA and RNA), and vitamins.
As always please check with your physician before adding or changing anything that might have an effect on your current treatment.

Nutrition is Closely Interrelated to Preventive Eye Care
Sep 3, 2010
By Eye Care
The eye performs the function of sensing light and transmitting the signals through the optic nerves to the brain. The brain registers the images and acts accordingly. The importance of this organ can never be overstated. When dealing with an organ as sensitive and as important as the eye, preventive eye care is always better than remedial eye cure.
Proper and timely eye care blunts macular degeneration, which is a harmful consequence of the natural process of aging. A simple habit of visiting the doctor periodically for a check up of the eyes helps a lot in preventing eye problems.
Nutrition and eye care is closely interrelated. Good food rich in vitamin A, E etc will protect you from eye problems. In this regard, it is pertinent to remember that:
• Carrot is a rich source of vitamin A
• Spinach is a rich source of Vitamin E. Vitamin E is an antioxidant. It slows the onset of macular degeneration and deterioration of eyesight.
• Vitamin E and Vitamin C strengthens connective tissues in the eye and thereby contributes to the eye health.
• Zinc and other such minerals are good for the eye. Omega-3 fatty acids, which is present in fish oil, reduces macular degeneration of nerve cells. It too contributes to ocular health.
• Aloe vera is rich in ambrotose. As a nutritional supplement, it prevents eye infections and improves immunity.
• Red Blood Cells are vital for the eyes as it ensures proper functioning of the brain and the nervous system. Vitamin B-12 is beneficial in this regard.
• Bilberry extract, aspalathus and mahonia grape extract are herbs that are beneficial for the eye. Bilberry is good for optic nerves and night vision. Aspalathus aids immunity and ocular health, as it is rich in antioxidants. Mahonia extract is good for the retina.
Just as physical exercises for the body keeps it fit and healthy, exercises for the eye improves overall eye health and eyesight. Regular exercises for the eye are a must.
• Strengthen eye muscles by alternatively concentrating on a tip of pencil placed a foot away and another farther object using just one eye.
• Deliberately blink 15 times in a minute to keep your eye clean, lubricated and tension free.
• Cure tunnel vision by training the mind to be aware of the complete scene. This helps in increasing awareness of peripheral images.
• Rapidly flutter blink for at least 25 times in a day.
You should take special care of your eyes if your answer to any of the following questions is in affirmative:
• Do you watch television for long periods sitting close to the TV? Is this true for your children?
• Does your computer monitor have an UV filter? Do you let children use such monitors?
• Are you a welder? Does your work other wise expose you to powerful UV radiation? Do you use proper safety goggles?
• Do you use sunglasses when you go out in the sun? Do you protect your eyes from harmful UV rays of the sun?
• Are you a chemist who experiments in laboratories? Are you otherwise exposed to UV light? Do you use protective equipment?

Top 10 Low Carb Power Foods
Aug 29 2010 Posted in Featured News, Health by Dina
Low Carb Fruits and Vegetables
If you’re low carb dieting, you have to pay special attention to foods that provide you the nutrition you need, but otherwise might be missing when you eliminate all high carb foods from your diet. It’s easy to make nutritious meals out of low carb foods by eating “power foods”, types of foods that really pack a powerhouse nutrition punch. These include nuts, fruits, and vegetables.
Here’s a list of the top 10 low carb power foods you should consider including in your diet. They are all in compliance with the popular Sonoma diet, as well. Although they’re numbered 10-1, they are all of great importance and impact.
Almonds
10. Almonds
Almonds are a high-protein food that, when eaten in moderation, can help promote weight loss and reduce cholesterol – which, in turn, reduces the risk of problems like heart disease. They are also a fantastic source of vitamin E, zinc, iron, magnesium, potassium, and fiber. Furthermore, they contain calcium, which makes them an effective replacement for dairy products. It’s important that you eat them in moderation, however, because they are high in fat and calories. Despite this, studies have shown that for unknown reasons, those who eat 500 calories worth of almonds vs. 500 calories of other foods tend to not gain weight as easily.
Bell Peppers
9. Bell peppers
Bell peppers of all varieties are packed with folic acid, vitamin C, vitamin B6, thiamine, and beta carotene. They are also contain exceptionally effective antioxidants which help reduce toxins in your body. Red bell peppers may be slightly healthier than green, because they contain lycopene, which is a type of carotene known to protect against cancer and heart disease. Bell peppers have been shown to reduce prevalence of everything from cataracts to heart attacks. If you have high cholesterol, you should consider adding bell peppers to your diet to limit your risk of heart disease.
Broccoli
8. Broccoli
Broccoli is an arsenal of nutritional benefits. Besides being easy to find throughout the year, and therefore an easy addition to any diet, there are a lot of tasty ways to prepare broccoli to combat its reputation as a bad-tasting veggie. Broccoli contains a lot of vitamin C which too can reduce the incidence of cataracts. It can also lessen the effects of colds. Broccoli’s potassium helps regulate high blood pressure, and its folic acid is very useful to pregnant women. With its rich fiber content it can help reduce cholesterol and regulate the gastrointestinal tract. There’s even some evidence that broccoli can prevent cancer, Alzheimer’s disease, diabetes, arthritis, and heart disease.
Extra Virgin Olive Oil
7. Extra virgin olive oil
Olive oil, preferably extra virgin, is a great source of monounsaturated fatty acids and antioxidants. It can reduce bad cholesterol (LDL) while increasing good cholesterol (HDL). This reduces the risk of heart disease, too. Olive oil stimulates the secretion of pancreatic hormones and bile, which can keep the gallbladder healthy. It can also protect the stomach against ulcers and gastritis. Some research even suggests it can help protect against colon cancer. Extra virgin olive oil contains the most antioxidants because it is less refined than other types of olive oil, and therefore considered healthier for you. But, olive oil is high in calories, so you should take that into account when adding it to your cooking or when drinking it as a supplement.
Blueberries
6. Blueberries
Blueberries are fine purveyors of antioxidants, containing more antioxidant properties than any other fresh fruit. Blueberries have vitamin C, vitamin E, B complex, anthocynin, copper, zinc, selenium, iron, and more. All of these can help boost your immune system and purify your body of toxins like free radicals, which keeps you healthier and reduces the effects of aging. In rats, blueberries have been shown to help reduce belly fat and the risk of cardiovascular disease. They also promote urinary tract health, keep vision healthy, keep the brain sharp, aid in digestion, fight cancer, and serve as antidepressants. They make a fantastic snack that don’t contain a lot of calories for the amount that should satisfy you.
Grapes
5. Grapes
Grapes are another antioxidant dream come true – noticing a theme? They are a robust source of flavonoids and also contain vitamin A, vitamin C, vitamin B, calcium, phosphorous, and protein. They can give you a great boost of energy. Grape juice can help fight rheumatism, liver problems, gout, and constipation. It also helps the kidneys function more effectively and easily. Grapes can also reduce the effects of certain viruses, and are known to help against the formation of blood clots. You can receive some of the benefits of grapes from eating them raw, in juice form, and in wine. Be careful when drinking wine, however, because it’s easier to add unwanted carbohydrates to your meals with wine consumption.
Strawberries
4. Strawberries
Strawberries have the lowest glycemic index of any fruit, which makes them excellent for low carb dieters. They’re a rich source of vitamin C which boost the immune system, among other things. They’re another excellent source of antioxidants – which are in fact believed to be the reason strawberries are so red. They fight cell-damaging free radicals. Although strawberries go badly quite quickly, they are extremely versatile and delicious in many different preparations, and can be easily purchased in the grocery store virtually any time of the year. The riper and redder the strawberry, the more nutritious it will be.
Tomatoes
3. Tomatoes
Another good source of lycopene, vitamin C, iron, and potassium. Lycopene serves as an effective antioxidant that can also fight cancer. In men, it’s been shown to reduce incidents of prostate cancer, though it’s not limited to that type of cancer
alone. Tomatoes are now thought to fight lung disease, particularly by blocking the same kinds of carcinogens that are so damaging in tobacco consumption. As with strawberries, the brighter and more red the tomatoes are, the healthier they are. Cooking tomatoes releases more of their beneficial nutrients. This means that canned tomatoes or tomato sauce are also good ways of benefiting from tomatoes in your diet.
Spinach
2. Spinach
Spinach may not turn you into Popeye, but it will give you a great deal of vitamins and minerals. It contains a lot of antioxidant beta-carotene, lutein, zeaxanthin, folate, calcium, folic acid, vitamin K, vitamin C, fiber, and iron. It has proven anti-cancer benefits. It can also protect eyes against macular degeneration. Its calcium will help strengthen bones. Its flavonoid content helps protect against age-related memory loss. Unlike tomatoes the greatest benefits of spinach can be extracted into your body when consumed raw or only lightly cooked.
Whole Grains
1. Whole grains
A grain is “whole” when its three parts, bran, germ and endosperm, are present in it. Whole grains can be an even better source of phytochemicals and antioxidants than fruits and vegetables. They are also good for iron, fiber, magnesium, B vitamins, and vitamin E. Whole grains can help reduce heart disease by preventing blood coagulation, high cholesterol, and high blood pressure. They can also help regulate blood sugar. Common types of whole grains include wild rice, whole wheat, oatmeal, barley, and popcorn. The fact that whole grains have a different spectrum of antioxidants than many fruits and vegetables earns them the #1 spot on this lis

Despite this, studies have shown that for unknown reasons, those who eat 500 calories worth of almonds vs. 500 calories of other foods tend to not gain weight as easily.
Bell Peppers
9. Bell peppers
Bell peppers of all varieties are packed with folic acid, vitamin C, vitamin B6, thiamine, and beta carotene. They are also contain exceptionally effective antioxidants which help reduce toxins in your body. Red bell peppers may be slightly healthier than green, because they contain lycopene, which is a type of carotene known to protect against cancer and heart disease. Bell peppers have been shown to reduce prevalence of everything from cataracts to heart attacks. If you have high cholesterol, you should consider adding bell peppers to your diet to limit your risk of heart disease.
Broccoli
8. Broccoli
Broccoli is an arsenal of nutritional benefits. Besides being easy to find throughout the year, and therefore an easy addition to any diet, there are a lot of tasty ways to prepare broccoli to combat its reputation as a bad-tasting veggie. Broccoli contains a lot of vitamin C which too can reduce the incidence of cataracts. It can also lessen the effects of colds. Broccoli’s potassium helps regulate high blood pressure, and its folic acid is very useful to pregnant women. With its rich fiber content it can help reduce cholesterol and regulate the gastrointestinal tract. There’s even some evidence that broccoli can prevent cancer, Alzheimer’s disease, diabetes, arthritis, and heart disease.
Extra Virgin Olive Oil
7. Extra virgin olive oil
Olive oil, preferably extra virgin, is a great source of monounsaturated fatty acids and antioxidants. It can reduce bad cholesterol (LDL) while increasing good cholesterol (HDL). This reduces the risk of heart disease, too. Olive oil stimulates the secretion of pancreatic hormones and bile, which can keep the gallbladder healthy. It can also protect the stomach against ulcers and gastritis. Some research even suggests it can help protect against colon cancer. Extra virgin olive oil contains the most antioxidants because it is less refined than other types of olive oil, and therefore considered healthier for you. But, olive oil is high in calories, so you should take that into account when adding it to your cooking or when drinking it as a supplement.
Blueberries
6. Blueberries
Blueberries are fine purveyors of antioxidants, containing more antioxidant properties than any other fresh fruit. Blueberries have vitamin C, vitamin E, B complex, anthocynin, copper, zinc, selenium, iron, and more. All of these can help boost your immune system and purify your body of toxins like free radicals, which keeps you healthier and reduces the effects of aging. In rats, blueberries have been shown to help reduce belly fat and the risk of cardiovascular disease. They also promote urinary tract health, keep vision healthy, keep the brain sharp, aid in digestion, fight cancer, and serve as antidepressants. They make a fantastic snack that don’t contain a lot of calories for the amount that should satisfy you.
Grapes
5. Grapes
Grapes are another antioxidant dream come true – noticing a theme? They are a robust source of flavonoids and also contain vitamin A, vitamin C, vitamin B, calcium, phosphorous, and protein. They can give you a great boost of energy. Grape juice can help fight rheumatism, liver problems, gout, and constipation. It also helps the kidneys function more effectively and easily. Grapes can also reduce the effects of certain viruses, and are known to help against the formation of blood clots. You can receive some of the benefits of grapes from eating them raw, in juice form, and in wine. Be careful when drinking wine, however, because it’s easier to add unwanted carbohydrates to your meals with wine consumption.
Strawberries
4. Strawberries
Strawberries have the lowest glycemic index of any fruit, which makes them excellent for low carb dieters. They’re a rich source of vitamin C which boost the immune system, among other things. They’re another excellent source of antioxidants – which are in fact believed to be the reason strawberries are so red. They fight cell-damaging free radicals. Although strawberries go badly quite quickly, they are extremely versatile and delicious in many different preparations, and can be easily purchased in the grocery store virtually any time of the year. The riper and redder the strawberry, the more nutritious it will be.
Tomatoes
3. Tomatoes
Another good source of lycopene, vitamin C, iron, and potassium. Lycopene serves as an effective antioxidant that can also fight cancer. In men, it’s been shown to reduce incidents of prostate cancer, though it’s not limited to that type of cancer
alone. Tomatoes are now thought to fight lung disease, particularly by blocking the same kinds of carcinogens that are so damaging in tobacco consumption. As with strawberries, the brighter and more red the tomatoes are, the healthier they are. Cooking tomatoes releases more of their beneficial nutrients. This means that canned tomatoes or tomato sauce are also good ways of benefiting from tomatoes in your diet.
Spinach
2. Spinach
Spinach may not turn you into Popeye, but it will give you a great deal of vitamins and minerals. It contains a lot of antioxidant beta-carotene, lutein, zeaxanthin, folate, calcium, folic acid, vitamin K, vitamin C, fiber, and iron. It has proven anti-cancer benefits. It can also protect eyes against macular degeneration. Its calcium will help strengthen bones. Its flavonoid content helps protect against age-related memory loss. Unlike tomatoes the greatest benefits of spinach can be extracted into your body when consumed raw or only lightly cooked.
Whole Grains
1. Whole grains
A grain is “whole” when its three parts, bran, germ and endosperm, are present in it. Whole grains can be an even better source of phytochemicals and antioxidants than fruits and vegetables. They are also good for iron, fiber, magnesium, B vitamins, and vitamin E. Whole grains can help reduce heart disease by preventing blood coagulation, high cholesterol, and high blood pressure. They can also help regulate blood sugar. Common types of whole grains include wild rice, whole wheat, oatmeal, barley, and popcorn. The fact that whole grains have a different spectrum of antioxidants than many fruits and vegetables earns them the #1 spot on this lis

Keeping Your Eyes Healthy Naturally
By: Dr. Grossman
When mom and dad told you to eat your carrots because they were good for your eyes, they were on the right track. As researchers continue to document that we really are what we eat, the role of nutrition in eye health becomes clearer and more important all the time.
In working with thousands of patients in my 25 years of practice I start my eye care prevention and treatment programs with a discussion with the patient regarding their diet. Consider these facts: more than 25 per cent of the nutrients we absorb from our food go to nourish our ?visual system?, our eyes and all of the nerves, blood vessels and tissues that support our vision. Indeed the concentration of Vitamin C in healthy eyes is higher than almost anywhere else in the body. It is not surprising then that proper nutrition plays an important role in preventing and treating problems such as cataracts, macular degeneration, glaucoma and dry eyes.
The diet plan we prescribe emphasizes a variety of whole foods with emphasis on fruits and vegetables. The body does not use each vitamin and mineral in isolation. The absence of one nutrient can affect the body’s ability to use another; for example, proper amounts of magnesium and vitamin D are needed to absorb and utilize calcium efficiently. Without adequate levels of zinc, the body cannot utilize all of the vitamin A it receives. Similarly, the B vitamins are needed together, working best as a team.
Eating a variety of whole foods and omitting processed sugar and other junk foods will help your body to get a wide range of nutrients. The body can lose a significant amount of nutrients when we eat nutrient poor foods. For example, we lose chromium and B vitamins as our body tries to burn white sugar. Therefore getting our nutrients if possible through healthy foods that we eat is a key to keeping good vision.
So what foods are the most important for eye health as mom told us? They are the fruits and vegetables. One study of over 100,000 people over a 12 to 18 year span at Brigham and Women’s Hospital in Boston found that those who ate three or more servings of fruit a day were 36% less likely to develop age-related macula degeneration than people who ate less than 1.5 per day.
It was also found that lutein and zeaxanthin were some of the most important nutrients to help protect the eye from cataracts and macular degeneration. In the Eye Disease Case Control Study, researchers found a significantly lower risk for developing these eye diseases in people with high amounts of lutein and zeaxanthin in their blood. Also, people who ate a diet with the most lutein and zeaxanthin (as much as 5.8 milligrams (mg) per day) had a significantly lower risk for macula degeneration than those whose diet contained the least amount (as low as 1.2 mg per day). Dietary studies confirmed the association between frequent consumption of spinach or collard greens, which are good sources of lutein and zeaxanthin, in lowering macula degeneration risk.
Let me give you some examples of how diet can be used in a preventive program for eye disease.
Let?s use the eye condition Open-angle Glaucoma as an example. Glaucoma is the second most common cause of blindness around the world: The condition affects approximately 60 million people. Glaucoma is an eye condition that overtime can damage the optic nerve, resulting in loss of peripheral vision (side vision), sometimes to the point of blindness if not treated. The damage is due to having chronically high eye pressure (referred to as ?intraocular pressure?). Unless evaluated by an eye doctor, most cases of glaucoma have no symptoms associated with it until the person starts to notice a lessening in peripheral vision.
So, let?s say you are 56 years old and the eye doctor finds you have borderline high eye pressures of 26 and 27 mm/Hg (normal range is 10 to 22 mm/Hg). At this point the eye doctor will most likely give you a visual fields test that maps your peripheral vision, and will also check the health of the optic nerve. If your visual field and optic nerve are fine, the doctor will either just monitor it regularly or possibly give medication to lower the pressure. Eye doctors rarely consider natural ways to lower eye pressure in possibly preventing the need for medication. A program which includes dietary changes, nutritional supplementation such as omega 3 essential fatty acids, alpha lipoic acid and vitamin C, and physical exercise have all been shown by research to help lower eye pressure naturally without medication.
Macular degeneration is even more frustrating in terms of eye doctors not prescribing natural approaches. Numerous peer review studies show that macular degeneration is a disease responsive to specific nutritional protocols. Most of the time the doctor just says there is nothing that can be done except possibly lasering the blood vessels that are leaking in the case of wet macular degeneration. Hundreds and hundreds of studies have shown the benefits of a nutritional program emphasizing the cartenoids lutein and zeaxanthin, anti-oxidants, the amino acid taurine, along with the benefits of micro current stimulation to help reduce the risk and decrease the progression of macular degeneration.
Other Tips
Besides nutrition the following are some important recommendations to keep your eyes healthy:
1. Don’t keep your eyes focused in one place for a sustained period of time. Change your focus. Look up out a window periodically when your doing close work to give your eyes a break. Sustained contraction of the eyes can also lead to a contraction of your upper body and neck. Don’t stare continuously without breaks as that causes tension on the visual system, and can contribute to vision problems.
2. Get at least 20 minutes of natural sunlight a day. Go for a walk. The eyes are light sensing organs. It’s important to get enough sunlight so that they operate optimally. Wear UV protective sunglasses to protect your eyes from damaging sun rays.
3. Quit smoking! Smokers have a significantly higher risk of eye disease than non-smokers.
4. Reduce sugar and alcohol intake

Bell Peppers rich in Vitamin A
It's important to protect the eyes all the time, but it becomes even more important in the summer with the increased sun exposure. The most common cause of vission loss and blindness in people over the age of 55 is age-related macular degeneration. This occurs when the central part of the retina (macula) becomes damaged and the most common cause of this damage is years of UV exposure.
One of the most important components in the retina is a vitamin - vitamin A to be exact. Thus, foods rich in this vitamin -- along with beta-carotene, zinc, and Vitamins C and E -- are beneficial to the eyes. Good sources of vitamin A (as beta-carotene) and vitamin C include dark green vegetables like kale, chard, and mustard greens, plus bell peppers, carrots, and blueberries. Lutein is also critical for eye health. Eggs and tomatoes are both rich sources of lutein.

"Quality" Carbs It's Not Just About Your Six-Pack
It seems as though every week we learn something new about the real power of nutrition. Recently, Agricultural Research Service (ARS) funded scientists at the Laboratory for Nutrition and Vision Research and found some interesting information.
Age related macular degeneration (AMD) and the vision loss associated with it may be connected to the “quality” of carbohydrates.
One study showed that a regular consumption of a “slow carb” ( low glycemic index) diet provided a protective effect against macular degeneration. A food’s glycemic index is an indicator of how fast the carbohydrate it contains will spike blood sugar levels.
So how do you keep your glycemic index in check? To learn more about which carbs produce only small fluctuations in our blood glucose and insulin levels, check out http://www.glycemicindex.com/ and follow their recommendations:
1. Pile half your dinner plate high with vegetables or salad
Aim to eat at least five serves of vegetables (this doesn’t include the starchy ones like potatoes, sweet potatoes or sweet corn) every day, and aim for foods with a variety of of colors.
2. Cut back on most potatoes
If you are a big potato eater and can’t bear the thought of giving them up, you don’t have to. Just cut back on the quantity. Don’t be afraid of trying other starchy vegetables like sweet potato, yams or taro, steamed, roasted or mashed.
3. Swap your bread
Choose a really grainy bread where you can actually see the grains, granary bread, stoneground wholemeal bread, real sourdough bread, soy and linseed bread, pumpernickel, fruit loaf or bread made from chickpea or other legume based flours.
4. Replace those high GI crunchy breakfast flakes
These refined breakfast cereals spike your blood glucose and insulin levels. Replace them with smart carbs like natural muesli or traditional (not instant) porridge oats or one of the lower GI processed breakfast cereals that will trickle fuel into your engine.
5. Make your starchy staples the low GI ones
Look for the low GI rice’s, serve your pasta al dente, choose less processed foods such as large flake or rolled oats for porridge or muesli and intact grains such as barley, buckwheat, bulgur, quinoa, whole kernel rye, or whole wheat kernels and opt for lower GI starchy vegetables.
6. Learn to love legumes!
Include legumes like beans, lentils and chickpeas in your meals two or three times a week, more often if you are vegetarian. Add chickpeas to a stir fry, red kidney beans to a chili, a bean salad to that barbecue menu, and beans or lentils to a casserole or soup.
7. Develop the art of combining
No need to cut out all high GI carbs. The trick is to combine them with those low GI tricklers to achieve a moderate overall GI. How? Lentils with rice (think of that delicious classic Italian soup), rice with beans and chili, tabbouli tucked into pita bread (with falafels and a dash of hummus), baked beans on toast or piled on a jacket-baked potato for classic comfort food.
8. Incorporate a lean protein source with every meal
Eat lean meat, skinless chicken, fish and seafood, eggs, milk, yoghurt or cheese, or legumes and tofu if you are vegetarian. The protein portion should make up around a quarter of the plate/meal.
9. Tickle your taste buds
Try vinaigrette (using vinegar or lemon juice with a dash of extra virgin olive oil) with salads, yogurt with cereal, lemon juice on vegetables like asparagus, or sourdough bread. These foods contain acids, which slow stomach emptying and lower your blood glucose response to the carbs in the meal.
10. Go low GI when snacking
If it is healthful and low GI, keep it handy. Grab fresh fruit, dried fruit, or fruit and nut mix, low fat milk and yogurt (or soy alternatives), fruit bread etc for snacks. Limit (this means don’t buy them every week) high GI refined flour products whether home baked or from the supermarket such as cookies, cakes, pastries, crumpets, crackers, biscuits, irrespective of their fat and sugar content. These really are the ‘keep for the occasional treat’ foods.
Keep your eye on the serving size. Remember portion caution with carb rich foods such as rice, al dente pasta and noodles, potatoes etc. Eating a huge amount of these foods, even of the low GI variety, will have a marked effect on your blood glucose. A cup of cooked noodles or al dente pasta or rice plus plenty of mixed non starchy vegetables and a little lean protein can turn into 3 cups of a very satisfying meal.
Most of all, recognize that protective nutrients are in each and every meal that you eat, and we all my have the power to stave off certain age related conditions.

A Diet Rich in Antioxidants Can Prevent Macular Degeneration and Blindness
Experts at Brigham Young University, United States, disclose that there occur two damaging mechanisms within the retina, which cause macular degeneration.Individuals who develop age related macular degeneration (ARMD), first suffer the loss of central-vision. Sooner or later, the individual loses complete vision.
Heidi Vollmer discovered that ARMD occurs due to a build-up of A2E, a natural by-product of various cellular processes. However, contrasting to other cellular by-products, A2E does not decompose, causing undue damage to the retina. The other factor responsible for ARMD is damage to the mitochondria within the cells. Excessive A2E disrupts the energy manufacture by the mitochondria, which consequently results in the death of the photo-receptors (cells for vision).
Studies were performed to test the photo-receptors of cows, rats and humans. Results showed that antioxidants prevent damage to the cells responsible for vision. What’s more, antioxidants can extend the life span of the photoreceptors and retinal cells.
What is Age Related Macular Degeneration?
Macula is that part of the retinal tissue where pictures and impressions are focused. It is predominantly responsible for our vision.
Importantly, ARMD has emerged as a principal cause for visual loss, world over.
Signs and Symptoms of Macular Degeneration
1.ARMD begins with obscuring of the vision.
2.Objects / pictures appear distorted or twisted.
3.One may visualize a dark area / patch in the center of the visual field.
4.Certain words may go missing, while reading.
5.Peripheral-vision is at first normal, but over a period of time it diminishes.
Preventive and Curative Measures : Diet to Prevent Macular Degeneration
Nutritionists and experts, world over, advise augmenting the daily diet with foods that support and maintain a healthy and good vision. Step up the intake of - carrots, tomatoes, spinach, kiwi, corn, Brussels sprouts, celery, bell peppers, broccoli, green leafy vegetables, apples and mangoes.
The following foods supply generous amounts of (lutein, zeaxanthin, and lycopene) anti-oxidants that stave off free radical damage to the photoreceptors and preserve vision :
1.Carrots: sustain good vision, even in old age. Carotene, found in abundance in carrots, shields the tissues of the eye from ARMD and checks the occurrence of cataract. Also, carrots supply large quantities of glutathione, the most powerful anti-aging agent. Carrots even prevent night blindness and encourage optimum night vision.
2.Spinach: loaded with lutein, spinach is vital for a healthy and good eyesight and is highly essential to prevent blurring of vision and blindness.

"Understanding Antioxidants and How They Can Benefit You"
Most of you are probably familiar with antioxidants, as it seems every company offering a supplement or food product uses that word as part of their marketing campaign. Even though it has become a part of our nutritional vocabulary, its' meaning may be somewhat unclear.
It appears that, in some way, the word seems to be related to oxygen, but how? On this page, I discuss what they are, and do, the most common ones, and common food sources.
What Are They and How Do They Work?
As we began our exploration of antioxidants, let's first break the word down into its component parts, okay? It can be broken down into two main parts: anti- and oxidant.
Most of us know what the first part, anti, means, obviously, it means against. But the second part, oxidant, may not be readily apparent.
Although oxygen is essential to human life, it can put into motion in your body a process that can have dangerous consequences. Oxidation occurs when a molecule loses an electron.
That molecule then becomes something we've discussed numerous times on this site, a free radical.
It is thought that free radicals attack every single cell in your body approximately 10,000 times a day. Unfortunately, as we age, the number of free radicals in our body increases.
From a cellular perspective, that free radical, at the very best, is a cell that doesn't perform the job it was originally designed to do.
At its worst, these altered cells can metamorphosize into more serious conditions such as cancer, diabetes, heart disease and macular degeneration.
If you've ever observed a peeled apple starting to turn brown after being exposed to the air for a few minutes, you're witnessing just how destructive oxidation can be.
What Benefits Do They Provide?
Here is a list of some of the advantages of antioxidants:
* Improvements in cognitive function - Cognitive function involves an improved ability to use information to meet the demands of everyday living.
* Slowing, even preventing, the development of cancer.
* Making you less likely to develop a cold, the flu, or viruses or infections
* Preventing the development of glaucoma and macular degeneration
* Slowing the aging process
* Reduced risk of developing heart disease
What Supplements Are Considered Antioxidants?
Here is a list of supplements that have antioxidant qualities and some foods where they can typically be found:
* Beta-carotene - broccoli, cantaloupe, carrots, squash, sweet potatoes, tomatoes
* Vitamin C - Citrus fruits like oranges and lime, broccoli, green leafy vegetables, strawberries, tomatoes
* Vitamin E - green leafy vegetables, nuts & seeds, vegetable oil, whole grains
* Selenium - chicken, eggs, fish, garlic, red meat
Here is a list of common phytochemicals:
* Alpha lipoic acd
* Flavonoids including anthocynidins, isoflavonoids, flavonols, flavones. Good food sources are fruits, vegetables, green tea, soybeans
* Grape seed extract
* Phenolic acids including caffeic acid, ferulic acid, coumaric acid, ellagic acid, gallic acid. Good food sources are berries, cherries, grapes, whole grains
* Quercetin
* Tannins including catechins. Good food sources are beans, grapes, lentils, tea
* Organosulfur compounds including allicin in garlic
It appears that, in some way, the word seems to be related to oxygen, but how? On this page, I discuss what they are, and do, the most common ones, and common food sources.
What Are They and How Do They Work?
As we began our exploration of antioxidants, let's first break the word down into its component parts, okay? It can be broken down into two main parts: anti- and oxidant.
Most of us know what the first part, anti, means, obviously, it means against. But the second part, oxidant, may not be readily apparent.
Although oxygen is essential to human life, it can put into motion in your body a process that can have dangerous consequences. Oxidation occurs when a molecule loses an electron.
That molecule then becomes something we've discussed numerous times on this site, a free radical.
It is thought that free radicals attack every single cell in your body approximately 10,000 times a day. Unfortunately, as we age, the number of free radicals in our body increases.
From a cellular perspective, that free radical, at the very best, is a cell that doesn't perform the job it was originally designed to do.
At its worst, these altered cells can metamorphosize into more serious conditions such as cancer, diabetes, heart disease and macular degeneration.
If you've ever observed a peeled apple starting to turn brown after being exposed to the air for a few minutes, you're witnessing just how destructive oxidation can be.
What Benefits Do They Provide?
Here is a list of some of the advantages of antioxidants:
* Improvements in cognitive function - Cognitive function involves an improved ability to use information to meet the demands of everyday living.
* Slowing, even preventing, the development of cancer.
* Making you less likely to develop a cold, the flu, or viruses or infections
* Preventing the development of glaucoma and macular degeneration
* Slowing the aging process
* Reduced risk of developing heart disease

Vitamin supplement phase II results find improvement in macular health for AMD sufferers, study says
Birmingham, AL—Results were released from the second phase of the Multifocal Electroretinogram (MERG) study of patients placed on supplemental vitamins, minerals, and carotenoids—a combination also known as macular health—to improve deteriorating maculas due to age-related macular degeneration (AMD).
"The conclusions of the new MERG study offer good news to sufferers of age-related macular degeneration," said John O. Mason III, MD, researcher and retina specialist at the Callahan Eye Foundation, the University of Alabama Birmingham (UAB). "This study is proof that the Macular Health vitamin is an incredible product for sufferers of this life-altering disease."
The study, accepted by the Association for Research and Vision in Ophthalmology (ARVO) for poster presentation, found that patients taking the Macular Health capsule once daily over a 2-year period had an increase in the health of the macula and better vision compared with a control group that did not take the Macular Health Capsule.
The first phase of the study found a 16 % increase in retinal improvement in patients taking Macular Health for 12 weeks. The second phase found a 17% increase in retinal improvement in the same patients after 2 years of taking Macular Health.
Dr. Mason and a team of retina specialists from UAB will continue to monitor participants in the study to evaluate long-term improvement in eye health and vision due to Macular Health.

Eyes at risk from eating a poor diet

Millions of people are putting their eyesight at risk with poor diets, experts warned yesterday.
Around 65 per cent of Britons could suffer problems because they are not getting enough vitamins, leafy green vegetables and oily fish.
The College of Optometrists said a good diet can prevent diseases such as Age Related Macular Degeneration.
But a survey found many people do not know of the link between food and eye health.
President Dr Rob Hogan said: "It's surprising so many people don't realise what we eat may affect our eyes.
"Most of us know the link between diet and heart disease, but we often take our eye health for granted." AMD, which damages the retina and leads to blindness, hits 26,000 people every year..

Carrots: Best friend of your eyes
A friend of mine recently let his contacts stay in their antibacterial pool longer than usual and embraced his new pair of glasses like a long lost friend. After complimenting him on his new purchase, I tried them on only to hear him tell me not to look through the lenses because he was “blind as a bat” and my eyes would end up in pain. Aside from thinking I should have my own eyes checked after almost a decade, I also wondered if there were any natural ways to keep my eyes healthy.
Carrots have long been thought of as an old wives tale of chomping on good-for-you vegetables masquerading as cures, but there is merit to the humble carrot. Carrots contain beta-carotene which is transformed into vitamin A by the body. Sure excess amounts of vitamin A may not ensure 20/20 vision, but it can help you maintain good eyesight. You can also get vitamin A from liver, broccoli, kale, sweet potatoes, pumpkins, mango, apricots, and cantaloupe, but carrots are best known for helping the eyes.
Beta-carotene isn’t the only compound found in carrots that is helpful—an antioxidant called lutein that primarily works with another component called zeaxanthin—and eating foods rich in these nutrients can increase the pigment density in the macula and added protection for your retina. Most of the foods with both of these nutrients are of the green and leafy variety.
As we age, our eyes get weaker and while over half of all Americans over 80 years of age have cataracts, over 13 million Americans are suffering from macular degeneration. The macula, part of the eye that helps keep the cones and rods in proper working order, has been under the microscope lately because a new study has linked vitamin B supplements to helping those with age-related macular degeneration. Macular degeneration is a widespread disease that attacks the area central to the retina and is a leading cause of vision loss in people over the age of 50.
A deficiency in vitamin A can also cause vision loss. Professor of Nutrition at Ohio State University, John Allred, says that extreme deficiency can cause night blindness and can even cause complete blindness, and is the leading cause of blindness in the third world alone. However, Allred says, if you are not deficient, drinking carrot juice every day or other beta-carotine enhanced veggies won’t improve your vision, only maintain it…and cause your skin to turn orange.
Beta-carotene, besides being broken down as a helpful vitamin within the body, is also a pigment. Experts say not to worry because even though the skin might appear to have an orange tint, it is completely harmless. If you cut back on the orange foods or drinks or consult your doctor to make sure your diet is balanced correctly, the tint will eventually lessen and go away and the excess of beta-carotene in your system will flush itself out. If you would rather not risk getting your vitamin A-carrying beta-carotene through orange tinted foods, most multi-vitamins include the nutrient for a quick source and readily available.
Unfortunately I did not find any helpful hints to share with my sight-challenged friend; I was pleased to find out that the urging of mothers everywhere to “eat your carrots” was not all a ruse. While I am still thinking of making an eye appointment and I am not 100 percent sure that my weekly carrot cake cravings are actually helping to keep my eyesight on a steady plateau, my eyes haven’t failed me yet and as long as my multi-vitamin can help me out, I will not worry about my eyes for no
