Nutrients Cut Macular Degeneration Risk?

Getting more vitamin D, methionine, and betaine in your diet is linked to lower incidence of the old age eye disease macular degeneration.

BOSTON (July 1) -- Eating a diet high in vitamin D, as well as the nutrients betaine and methionine, might help reduce the risk of macular degeneration, according to new research conducted by Tufts Medical Center scientists. Their study of identical twins from the US World War II Twin Registry also found that the more a person smoked, the higher their risk of developing macular degeneration. The study, "Smoking, Dietary Betaine, Methionine, and Vitamin D in Monozygotic Twins with Discordant Macular Degeneration: Epigenetic Implications” published in the journal Ophthalmology on July 1, is the first to look at identical twin pairs in which one twin had early age-related macular degeneration (AMD), and the other had late stage AMD.

Eat your spinach with fish or poultry.

Similarly, Dr. Seddon’s research team also found that higher intakes of betaine and methionine were linked to a slower progression of the disease. These nutrients have also been linked to epigenetic mechanisms, which is a change in DNA, not attributable to a change in the actual DNA sequence. Betaine is found in fish, grains and spinach, while methionine is found in poultry, fish and dairy foods.

Quinoa, beets and shellfish are very good betaine sources.

Omega-3 and -6 fats also appear to play a role. One study I found used the phrase "prevent".

I posted the details http://yelling-stop.blogspot.com/2011/02/linoleic-acid-and-blindness.html.
