A new study suggests that older adults who eat diets rich in citrus fruits, leafy greens and fish oil may have a lower risk of age-related macular degeneration (AMD), the leading cause of vision loss among older U.S. adults.
AMD 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.
Researchers looked at the overall diet patterns of 4,000 older adults, and found that participants with diets high in omega-3 fats, 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.
