Joy Bauer's Food Cures Part 32

BETA CAROTENE, VITAMIN C, VITAMIN E.

A study led by researchers from Erasmus Medical Centre in Rotterdam, the Netherlands, followed a group of more than 4,000 people to see how diet affected the risk of developing macular degeneration. After eight years, the scientists compared the diets of people who developed the condition with the diets of those who did not. The results were encouraging: People who ate a diet rich in beta carotene, vitamin C, vitamin E, and zinc had a 35 percent reduced risk of developing macular degeneration compared with people who ate an average diet. And those who ate worse-than-normal diets, with low levels of those nutrients, actually had a 20 percent increased increased risk of disease. I highly recommend that anyone with a family history of macular degeneration follow the food plan for high-antioxidant, high-zinc foods to reduce their risk. For an easy way to get a large dose of all the nutrients, try one of my Smooth-SEE recipes (Chapter 11). risk of disease.

FAQSMy doctor suggested that I cut down on sugary foods to try to prevent cataracts. I've never heard that before-is it good advice?

Cutting back on sugary foods is always a good idea. Whether it will help prevent cataracts is a hot research topic right now. Some scientists from Tufts University a.n.a.lyzed data from AREDS and discovered that eating lots of low-quality carbohydrates increased the risk of cataracts by up to 50 percent. Low-quality carbohydrates are defined as sugary foods, white rice, and anything made with refined white flour, including crackers, breads, rolls, m.u.f.fins, pasta, and other baked goods. The theory is that these foods quickly raise blood sugars to very high levels and that there's a c.u.mulative effect. In other words, the more low quality carbs you eat, the more you expose the lens of your eye to potentially dangerous levels of sugar. So if you want another fabulous reason to eat healthier foods-including more fruits, vegetables, and high-quality carbohydrates, such as whole grain food and brown rice-there it is.

ZINC.

AREDS and the Rotterdam study confirmed zinc's role in eye health. Zinc is found in the retina, and helps the functioning of enzymes responsible for eye health. In people with macular degeneration, levels of zinc in the retina can be very low, so eating zinc-rich foods is a logical first step for preventing and treating macular degeneration.

BEST FOODS FOR ZINC: Oysters, lean beef, crab, ostrich, pork tenderloin, peanut b.u.t.ter, wheat germ, turkey, veal, pumpkin seeds, chicken, chickpeas (garbanzo beans), fat-free yogurt, fortified whole grain cereals, pine nuts, cashews, sunflower seeds, lima beans, lentils, pecans, cheese (fat-free, reduced-fat), fat-free milk, almonds, walnuts, peanuts, black-eyed peas, green peas Oysters, lean beef, crab, ostrich, pork tenderloin, peanut b.u.t.ter, wheat germ, turkey, veal, pumpkin seeds, chicken, chickpeas (garbanzo beans), fat-free yogurt, fortified whole grain cereals, pine nuts, cashews, sunflower seeds, lima beans, lentils, pecans, cheese (fat-free, reduced-fat), fat-free milk, almonds, walnuts, peanuts, black-eyed peas, green peas LUTEIN AND ZEAXANTHIN.

Lutein and zeaxanthin are a matched pair of antioxidants-almost without exception, foods that contain one also contain the other. And they are found in high concentrations in the tissue of the macula. Because they absorb 40 to 90 percent of blue light intensity, these nutrients act like sunscreen for your eyes. Studies have shown that eating foods rich in lutein and zeaxanthin can increase increase the pigment density in the macula-and greater pigment density means better retina protection, and a lower risk of macular degeneration. At least one study has confirmed that eating foods with high amounts of these antioxidants seems to reduce the risk of developing macular degeneration. the pigment density in the macula-and greater pigment density means better retina protection, and a lower risk of macular degeneration.

FAQSLet's say I try changing my diet to help my macular degeneration, when should I start to see results?

It varies from person to person. Some people might see a dramatic change after just one month, while others may only notice subtle changes, and still others may have to wait for their next ophthalmologist appointment when they are surprised to discover that they do better on the eye exam. But don't lose faith-all those eye-healthy vitamins and minerals are also helping to keep the rest of you healthy, too!

OMEGA-3 FATTY ACIDS.

Retinal pigment cells contain a type of omega-3 called docosahexaenoic acid (DHA), which helps protect light receptor cells in the eye from damage by sunlight and free radicals. In 2006, scientists speculated that fish oil and other sources of omega-3 fatty acids could be natural protection against age-related macular degeneration. If you want to take advantage of this research, I recommend eating two to three servings of fatty fish each week, and strive to incorporate the other omega-rich foods into your daily diet, too.

BEST FOODS FOR OMEGA-3 FATTY ACIDS: Wild salmon (fresh, canned), herring, mackerel (not king), sardines, anchovies, rainbow trout, Pacific oysters, omega-3-fortified eggs, flaxseed (ground and oil), walnuts, b.u.t.ternuts (white walnuts), seaweed, walnut oil, canola oil, soybeans Wild salmon (fresh, canned), herring, mackerel (not king), sardines, anchovies, rainbow trout, Pacific oysters, omega-3-fortified eggs, flaxseed (ground and oil), walnuts, b.u.t.ternuts (white walnuts), seaweed, walnut oil, canola oil, soybeans BONUS POINTS.

- Get regular eye exams. It is important to get a regular comprehensive checkup by an optometrist or ophthalmologist-at least once a year if you're over age 60. Be sure that the exam includes eye dilation so that any change in your lens or retina can be spotted easily and early.

- Protect your eyes from the sun. One of the top causes of cataracts is radiation from the sun. Take steps to protect your eyes by wearing sungla.s.ses and a hat with a brim whenever you are out in bright daylight. One of the top causes of cataracts is radiation from the sun.

- Stop smoking. Smoking increases your risk of both cataracts and macular degeneration, in part because it creates free radicals, and in part because smoking decreases the amount of oxygen to the eye. Smoking increases your risk of both cataracts and macular degeneration, in part because it creates free radicals, and in part because smoking decreases the amount of oxygen to the eye.

- If you smoke, don't drink alcohol or take beta carotene supplements. I strongly encourage you to stop smoking, but if you haven't yet quit entirely, you have a couple other guidelines. Although alcohol alone doesn't increase the risk for cataracts, smokers who drink alcohol have a greater risk than smokers who don't drink. And beta carotene supplements may increase the risk of lung cancer in smokers, so that's a dangerous combination.

- Maintain a healthy weight. People with early-stage macular degeneration who are also overweight have double the risk of moving on to the advanced stage, so losing weight may help keep the disease from progressing. Plus, people who are overweight have a greater risk of developing type 2 diabetes, which increases the risk of cataracts. (See Weight Loss on Chapter 3 for more information.)

(See Weight Loss on Chapter 3 for more information.) - Avoid eating foods high in saturated and trans fats. b.u.t.ter, stick margarine, cream, whole milk, ice cream, lard, cheese, beef fat, products made with hydrogenated oil, and other damaging fats can cause a buildup of plaque in blood vessels which can choke off blood flow-including blood flow to the eye. Any decrease in oxygen can harm the eye and promote tissue damage. b.u.t.ter, stick margarine, cream, whole milk, ice cream, lard, cheese, beef fat, products made with hydrogenated oil, and other damaging fats can cause a buildup of plaque in blood vessels which can choke off blood flow-including blood flow to the eye.

SUPPLEMENTS.

FOR CATARACTS.

If you are concerned about cataracts and want to consider supplements in addition to in addition to the food fixes, my only recommendation is for: the food fixes, my only recommendation is for: - Multivitamin. It is important to get the necessary amounts of the cataract-fighting B vitamins, along with a basic amount of vitamin C and E. Look for a standard multivitamin that contains 100 percent of vitamins C and E. Too much vitamin C from supplemental doses might actually increase the risk of cataracts...and too much vitamin E from supplemental doses might increase the risk of macular degeneration. Supplements with "mega" doses of any vitamin or mineral are not recommended.

FOR MACULAR DEGENERATION ONLY.

For people who have been diagnosed with macular degeneration, the following supplements may help slow progression of the disease. Among the best studied are daily dosages of the following supplements: I RECOMMEND THAT EVERYONE TAKE.

- Multivitamin that provides only only 100% DV for Vitamin E. 100% DV for Vitamin E.

AND SPEAK WITH YOUR DOCTOR ABOUT THESE.

ADDITIONAL SUPPLEMENTS.

- 500 milligrams vitamin C.

- 15 milligrams beta carotene. Smokers shouldn't take beta carotene because it may increase the risk of cancer (in smokers only).

- 80 milligrams zinc, with 2 milligrams copper to balance out the effect of such high levels of zinc, which can depress the immune system and block copper's availability in the body.

JOY'S 4-STEP PROGRAM FOR CATARACTS AND MACULAR DEGENERATION Follow this program if you have macular degeneration or cataracts, or a family history of these diseases.

STEP 1...START WITH THE BASICS These are the first things you should do to address eye problems: - See an optometrist or ophthalmologist for a comprehensive eye exam. If you are over age 60, have an exam every two years. If you notice any vision changes, see a doctor immediately-don't wait for your next appointment.

- If you have macular degeneration, talk with your physician about whether you are a good candidate to take the AREDS supplements, and whether you need to avoid zinc or beta carotene.

- If you smoke, quit.

- Protect your eyes from the sun by wearing a brimmed hat and sungla.s.ses whenever possible.

STEP 2...YOUR ULTIMATE GROCERY LIST A nutrition plan is only as good as the foods that you choose. This list contains foods with high levels of nutrients that contribute to eye health, plus some foods used as ingredients in the meal plans and recipes. You don't have to purchase every item...but these foods should make up the bulk of what you eat for the week. If you find yourself getting bored, try adding a food from the list that's new to you. My practice is full of people who are pa.s.sionate fans of foods they've only recently started eating.

STEP 3...GOING ABOVE AND BEYOND If you want to do everything you can for eye health, here are some additional things you might try: - If you like, feel free to take a multivitamin with 100% DV for B vitamins and folic acid. Look for a supplement that contains no more than 100% DV of any nutrient, especially vitamins C and E.

- If you specifically have macular degeneration (not cataracts), consider supplements of vitamin C, beta carotene, and zinc with copper, in the dosages recommended on Chapter 11. At the very least, make sure your multivitamin provides 100% DV for beta carotene, zinc, and copper. If you smoke, cross beta carotene off your list. These are treatment-level dosages-if you do not have macular degeneration, do not take these supplements.

- Avoid eating foods high in saturated and trans fats, including b.u.t.ter, stick margarine, ice cream, whole milk, cheese, and products made with hydrogenated oils.

SUNGLa.s.sESYour choice of sungla.s.ses makes a fas.h.i.+on statement, but please don't let that statement include the words eye damage eye damage. Not all designer models protect the eyes. Don't be fooled into thinking that large or dark lenses necessarily protect against radiation. The American Academy of Ophthalmology recommends choosing sungla.s.ses that are certified to block 99 to 100 percent of UVA and UVB radiation. Gla.s.ses should fit well so they don't slide down your nose. If possible, look for models that wrap all the way around to your temples. Wear your sungla.s.ses every time you go outside, even on cloudy days-radiation is still there even if the sun is hidden. If you wear contact lenses with UV protection, it is still important to wear sungla.s.ses because contacts cover only a tiny portion of your eyes.

STEP 4...MEAL PLANS These sample menus include foods high in nutrients that have been shown to be protective against cataracts and macular degeneration, specifically antioxidants, beta carotene, vitamins C and E, zinc, B vitamins, and lutein.
