How to Help Prevent Macular Degeneration by Marc Grossman, O.D., L.Ac

Stop smoking

This is one of the most important things you can do to prevent damage to your vision. A 2005 review of research pointed out that 13 separate studies found that there was a statistically significant tie between the habit of smoking and the development of macular degeneration. The risk in smokers was two to three times higher than in non-smokers.6 A 2015 study identified damage and inflammation caused by smoking to several layers of the macula: the pigmented layer, Bruch’s membrane, the choroidal stroma.7 Additional studies in 2016 verify this finding. Learn more about research on smoking and macular degeneration.

Protect against blue light. Wear sunglasses (wear wraparound sunglasses especially if you have been diagnosed with AMD) that are UV resistant to protect your eyes against damage from blue light.

Leafy greens. Make sure your diet includes plenty of fresh, preferably organic, dark leafy greens. These vegetables are rich in carotenoids, the colored pigments that your eye needs, especially lutein and zeathanthin. Even if you don’t like vegetables such as collards, kale and spinach, you can add them to soups, puree them in green drinks, juice them with other fruits and vegetables, or add them to other greens in salads. Many studies report that the nutrients found in these healthy vegetables lower the risk of developing macular degeneration.

Low fat diet. The Western diet, high in fats, is associated with a higher risk of macular degeneration. Researchers have found that a high fat diet gives rise to weak gut microbiota resulting in poor digestion and long-range, low-grade inflammation in the entire body. These factors appear to be the source of high rates of AMD in men who are overweight.

Daily juicing. A great way to get the nutrients from leafy greens is juicing of vegetables and fruits (preferably organic). See our juicing recipe to support the health of the macula.

AREDS. The nutrients specified in the 2001 AREDS (which investigated vitamins C and E, beta-carotene and zinc) were found to reduce the risk of advanced AMD by about 25%. The AREDS formula includes: 500mg vitamin C; 400 IU vitamin E, 15 mg beta-carotene, 80mg zinc, 2 mg copper.

AREDS2. The nutrients tested in the 2006 (which added omega-3 fatty acids, lutein and zeaxanthin to, and reduced zinc and beta-carotene in the AREDS formula), were found to further reduce the risk of advanced AMD. As a result of AREDS2 the formula was revised to: 500mg vitamin C; 400 IU vitamin E, 10mg lutein, 2mg zeaxanthin, 350mg DHA, 650mg EPA, 25mg zinc and no beta-carotene.

Zinc. A note for vegetarians: The AREDs studies found that zinc is necessary for a healthy macula: 11mg daily for men and 8mg daily for women. Zinc is abundant in meat and seafood. It is also abundant in nuts, grains and legumes, but not in a readily absorbable form. The body does not store zinc well, so zinc supplementation might be needed for vegetarians and vegans.14 Consult your medical provider.

Other nutrients Other research has determined that astaxanthin10, and meso-zeaxanthin, other potent antioxidants, are important. Vitamin C has been found to enhance the absorption of lutein.

Resveratrol has been found to inhibit the growth of new blood vessels in the advanced form of macular degeneration, choroidal neovascularization.16, 17

Omega 3 fatty acids. Many research studies have established that omega 3 fatty acids lower the risk of macular degeneration.8 Omega 3s have the ability to regulate formation of extraneous blood vessels that distort vision.9 Eating fish is a great way to increase omega 3 in your diet.

Omega 6 to Omega 3 Ratio. The standard western diet tends to be very high in omega 6 fatty acids, with a ratio of about 10-20:1. The Mediterranean diet has a higher proportion of omega-3; the ratio is about 4-5:1. This ratio is associated with a protective effect against the severe neovascular form of ARMD.15

Vitamin D3. Low levels of vitamin D3 in the body are associated with increases in macular degeneration symptoms. D3 has anti-inflammation and anti-angiogenic capacities and has the greatest benefit in patients where the genetic risk is greatest.11 Because D3 has an important role in the immune system and aging process it is important in age-related conditions such as macular degeneration where the retina suffers age-related damage.

Preventing Eye Disease by Marc Grossman, O.D., LAc & Michael Edson, M.S., LAc

The typical Western diet, with refined grains, too many sugars and processed foods and poor oils is an inflammatory diet, contributing to or ultimately causing chronic inflammatory disease, cardiovascular disease, diabetes, dementia and eye issues. The high inflammation level in the body is reported to be an important factor in premature mortality. Diets rich in fruits and vegetables as well as being low in refined carbohydrates, along with targeted supplementation of antioxidants helps keep one’s body and eyes healthy and free of disease.

How to Take Care of Your Eyes by Dr. Marc Grossman, OD, LAc

Headaches, squinting and eyes that burn, ache, water or tire easily are indications that the visual system needs help. Most people are born with the potential for good eyes and sight. Vision, however, is learned. And the way you use and care for your visual system directly affects your enjoyment of play, school or work. Your visual system can undergo tremendous stress.

Helping Our Aging Eyes by Dr. Marc Grossman, OD, LAc

Problems with eyesight can occur at any age, but in seniors they are more common. For most eye conditions, the risk rate increases for those over 70- or 80-years old. However, many of the eye conditions that arise as a result of age are considered to be normal by many medical professionals, although physiological or biological compensations are possible. Aging does increase the risk for some sight-threatening eye conditions, which is why it is important to be informed and to have regular eye check-ups.

Integrative Vision Care & Nutrition by Marc Grossman, OD, LAc

Mind/Body medicine is based on the fact that our health and well-being depend on all the individual parts to work together effectively. So it should come as no surprise that healthy eyesight is also dependent upon our total well-being, which is affected by our genetic makeup, the food we eat, our work environment and exposure to airborne toxins, as well as our general belief systems about ourselves and the world we live in.
