(OrganicJar) A new study suggests that older adults who eat diets rich in citrus fruits, leafy greens and fish oil, but low in glycemic index 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.
Foods To Eat:
Researchers found that participants who tended to eat fish like salmon and mackerel that are rich in omega-3 fatty acids, or foods high in vitamin C, vitamin E, zinc, lutein and zeaxanthin, had a relatively lower risk of AMD. Lutein and zeaxanthin are plant pigments that act as antioxidants; the nutrients are found in broccoli, spinach and other leafy green vegetables, as well as egg yolks.
