Nutrition and Eye Care

Eye disease is one of the most common causes of permanent disability in the United States. More than 20 million Americans age 40 and older have cataracts, and 10 million Americans age 60 and over have age-related macular degeneration. These eye diseases occur as we grow older, and proper nutrition may have some affect on both of them.

AMD occurs when cells in the macula of the eye die. The macula is located in the center of the retina in the back of the eye, and is responsible for your sharp, central vision, which you need for reading and other tasks that require good eyesight. Once the macula is damaged, your vision is no longer clear, and you cannot make out fine details of objects. There is no cure for AMD, but proper nutrition may help prevent it from worsening.

The nutrients associated with eye health are vitamins C and E; carotenoids, beta carotene, lutein, and zeaxanthin; omega-3 fatty acids; zinc; and vitamins B6, B9 (folic acid or folate), and B12.

"Antioxidants, especially lutein, help deter build-up of waste products in the retina, which in turn helps reduce your risk for AMD,” says Jennifer K. Nelson, MS, RD, director of clinical dietetics and associate professor of nutrition at the Mayo School of Health Sciences in Rochester, Minn. “Folate and vitamin B6 decrease the presence of the blood chemical homocysteine, which lowers your risk for AMD. Antioxidants also help prevent the cross linking of proteins in the lens which can cause cataracts.”

A diet high in refined carbohydrates, such as white rice, white bread, and pasta, may actually increase your risk of developing AMD. These foods have a high glycemic index, which means they are broken down rapidly into blood glucose or sugar. Choose breads and pasta made from whole grains and brown rice for your complex carbohydrates.

On a personal note, I have realized how important proper nutrition and the right combination of vitamins and minerals are. Most of my life I have needed to wear some sort of eye correction. I could not even watch TV without my contacts in. The whole world was basically a blur. As I have improved my nutrition, adding the all important Vitamin B6, B12,Folic Acid and Antioxidants. Things started to change, things were not so blurry! Well, now after 2+ years, I no longer need contacts.
