Diet Factors Help Prevent Age-related Macular Degeneration

A new study adds to the evidence that eating wisely helps protect our eyes from age-related macular degeneration (AMD), a potentially blinding disease that affects millions of older Americans. The researchers found that people whose diets had higher levels of certain nutrients— vitamins C and E, zinc, lutein, zeaxanthin, omega-3 fatty acids DHA and EPA—and also had high levels of low-glycemic index (low-GI) foods, were less likely to develop early and advanced AMD. This study is the first to look at these dietary factors in relation to AMD.

Although the researchers say clinical studies are needed before physicians can make specific recommendations to AMD patients, there’s no need to delay adding healthy food to your shopping cart. Sources of AMD-protective nutrients include citrus fruits, vegetable oils, nuts, whole grains, dark green leafy vegetables and cold water fish.  Anyone who has diabetes or has tried a low-GI diet to lose weight is familiar with glycemic index charts. The GI value is based on how fast a food’s carbohydrates raise the body’s blood sugar levels; low GI foods have less impact on blood sugar fluctuations.

AMD affects the retina, the light-sensitive tissue at the back of the eye. Advanced AMD can destroy the central, detailed vision that we need to read, drive, and enjoy daily life. Although the “wet” form of advanced AMD is often treatable, there’s no effective treatment for the much more common “dry” form.  Eating well is a practical way to reduce AMD risk while enjoying better health.
