NEW YORK (Reuters Health) - A new study suggests that older adults who eat diets rich in citrus fruits, leafy greens and fish oil, but low in "glycemic index," may have a lower risk of age-related macular degeneration -- the leading cause of vision loss among older U.S. adults.
AMD, also known as "age-related macular degeneration" refers to gradual damage to the macula, a structure in the retina that allows for seeing fine detail. The condition affects more than 1 million Americans, usually after the age of 65.
A number of studies have suggested that individual nutrients, including the antioxidants lutein, vitamin C and vitamin E, can help protect against AMD. This latest study, published in the journal Ophthalmology, looked at the overall diet patterns of 4,000 older adults and the links to AMD risk.
