Did you know that age-related macular degeneration, aka AMD, is the leading cause of vision loss as you get older? Do you have friends or family members who are losing their vision?

Perhaps they’ve been diagnosed with AMD, which affects the central vision and results in significant vision loss or even blindness. Spots, referred to as blind spots, cloud this central vision making it very difficult to see faces clearly, read and drive. And don’t miss this. If you have a family history of AMD, are female or white…all three increase your risk.

What if you can add certain foods to your diet NOW to help prevent AMD down the road? Data from the Age-Related Eye Disease Study (known as AREDS) reported in the May 2009 issue of the journal Ophthalmology found that participants whose diets were high in certain nutrients including vitamin E and C, zinc, lutein, zeaxanthin, and omega-3 fats had the lowest risks of age-related macular degeneration.

Other studies suggest that a diet consisting of more low-glycemic foods (vegetables, fruits, beans, lentils and whole grains as examples) and less high glycemic foods such as candy, desserts, and sweetened drinks results in a lower risk for AMD.

In case you’re wondering how refined or processed foods, which are typically high on the glycemic index affect vision, here is what scientists currently believe. High-GI foods cause a rapid increase and decline in blood glucose levels as opposed to low-GI foods that raise blood glucose more slowly.

The rapid rise in blood glucose may damage the macula or part of the retina, which provides detailed central vision. The good news is that the certain nutrients just mentioned above seem to help protect your eyes from AMD.

Consider making these foods a staple in your diet.

1. Citrus fruits, kiwi, berries, potatoes, tomatoes: Vitamin C
   
2. Nuts (walnuts have fats that convert to omega-3s in the body): Zinc, Vitamin E and healthy fats 
3. Red meat, poultry, beans, nuts, seafood (such as crab and lobster), whole grains, fortified breakfast cereals, and dairy products: zinc
   
4. Dark green leafy veggies such as broccoli, spinach, kale plus yellow foods such as corn and egg yolks: carotenoids: lutein
   and zeaxanthin.
   
5. Cold-water fish like salmon or canned tuna: omega-3 fats

The good news is that all the foods mentioned above are not only beneficial for eye health but for your total body health.
