Foods for Eye Health
Approximately 10 million people in the U.S. suffer from macular degeneration, and over half of all Americans over 80 have cataracts. According to the CDC, around 21 million Americans have some sort of functional vision problem or eye condition, and vision loss is among the top 10 reported disabilities in adults in the US.
So what can we do to protects our eyes? Head to the supermarket of course! Research conducted by the National Eye Institute demonstrated that there are several nutrients that can help protect our eyes. The most important foods for eye health are those that are rich in the antioxidants beta-carotene, vitamin C, vitamin E, lutein and zeaxanthin, as well as zinc and omega-3s.
Here are some foods to add to your shopping list today!
Carrots, sweet potatoes, and apricots are loaded with beta-carotene, an antioxidant that helps reduce the risk of macular degeneration and cataracts.
Brussels sprouts, and bell peppers pack vitamin C another antioxidant that protects the entire body including our eyes.
Turkey, oysters, and pumpkin seeds, are all rich in zinc. Low levels of have been linked to impaired vision and poor night vision, as well as cloudy cataracts. In addition to zinc, turkey also contains niacin, the B-vitamin that specifically protects against cataracts.
Spinach provides four eye-protecting nutrients: vitamin C, beta-carotene, lutein and zeaxanthin. Studies have shown that eating foods rich in lutein and zeaxanthin can increase the pigment density in the macula; and greater pigment density means better retina protection, and a lower risk of macular degeneration. Because they absorb 40 to 90 percent of blue light intensity, these nutrients act like sunscreen for your eyes. Other great sources of lutein and zeaxanthin include, dark green leafy veggies, squash, peas, corn, pumpkin, peppers, kiwi, Brussels sprouts and broccoli. Eggs and oranges also contain small amounts.
Salmon, sardines and other omega 3 rich foods including hemp, and chia seeds are also beneficial for eye health. Studies have shown that regularly eating foods rich in omega-3s can help protect tiny blood vessels within the eyes. Sprinkle chia and hemp seeds on salads, soups and breakfast oatmeal, and aim for two to three four ounce portions of oily fish per week.
Vitamin E rich foods may also boost eye health and include wheat germ, almonds, sunflower seeds, pine nuts, cooked spinach, apricots, olives and more.
