People often believe that failing eyesight is an inevitable result of aging or eye strain. In truth, a healthy lifestyle can significantly reduce the risk of eye health problems.
Sunflower Seeds and Nuts
An ounce of these seeds or almonds has half the amount of vitamin E the USDA recommends for adults each day. A large study found that vitamin E, together with other nutrients, can help slow age-related macular degeneration (AMD) from getting worse. It may also help prevent cataracts. Hazelnuts, peanuts (technically legumes), and peanut butter are also good sources of vitamin E.
The yolk is a prime source of lutein and zeaxanthin—plus zinc, which also helps reduce your macular degeneration risk.
Your retinas need two types of omega-3 fatty acids to work right: DHA and EPA. You can find both in fatty fish, such as salmon, tuna, and trout, as well as other seafood. Omega-3s also seem to protect your eyes from AMD and glaucoma. Low levels of these fatty acids have been linked to dry eyes.
Dark, Leafy Greens
Kale, spinach, and collard greens, for example, are rich in both vitamins C and E. They also have the carotenoids lutein and zeaxanthin. These plant-based forms of vitamin A lower your risk of long-term eye diseases, including AMD and cataracts. Most people who eat Western diets don’t get enough of them.
Broccoli and Brussels Sprouts
These related veggies come with another winning combination of nutrients: vitamin A (as lutein, zeaxanthin, and beta-carotene), vitamin C, and vitamin E. They’re all antioxidants that protect the cells in your eyes from free radicals, a type of unstable molecule that breaks down healthy tissue. Your retinas are especially vulnerable.
