Lean Meat and Poultry
Zinc brings vitamin A from your liver to your retina, where it’s used to make the protective pigment melanin. Oysters have more zinc per serving than any other food, but you don’t have to be a shellfish lover to get enough: Beef, pork, and chicken (both dark and breast meat) are all good sources.
Beans and Legumes
Prefer a vegetarian, low-fat, high-fiber option to help keep your vision sharp at night and slow AMD? Chickpeas are also high in zinc, as are black-eyed peas, kidney beans, and lentils. A can of baked beans will do the job, too.
It’s a great package deal: The zinc in an egg will help your body use the lutein and zeaxanthin from its yolk. The yellow-orange color of these compounds blocks harmful blue light from damaging your retina. They help boost the amount of protective pigment in the macula, the part of your eye that controls central vision.
Your body can’t make lutein and zeaxanthin, but you can get them from squash all year long. Summer squash also has vitamin C and zinc. The winter kind will give you vitamins A and C as well as omega-3 fatty acids, too.
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.
