Eye Health and NutritionJanet Noe
In regards to eye health, you have probably heard “Eat your carrots, they’re good for your eyes!” from mom several times throughout childhood. There are several foods that contain vitamins and nutrients essential for eye health. Protect your peepers by consuming more of the following. . .
Brightly colored Fruits and Vegetables – Yes, carrots are on the list of top foods for eye health. So are bell peppers, strawberries, pumpkin, corn and canteloupe and other yellow, orange and red fruit and veggies. Carotenoids are the compounds responsible for this bright coloring and help decrease the risk of many eye diseases. The Vitamin C found in many of these fruits and vegetables also lowers your risk of developing cataracts. Mom was right! Carrots and other foods which contain Vitamin A or retinol help your body to synthesize a pigment in your eyes that operates in low light conditions called rhodopsin. Vitamin A deficiency can lead to night blindness.
Fish – Cold-water fish such as salmon, tuna, sardines and mackerel are rich in omega-3 fatty acids, which offer protection against dry eyes, macular degeneration and cataracts. Tuna, Salmon, anchovies and trout have high levels of a type of omega 3 called DHA, a fatty acid esential for the health of the retinas but one that our bodies don’t make efficiently. We need to replenish DHA with food rich in this nutrient. Low levels of DHA are linked to dry eye syndrome.
Nuts – Pistachios, walnuts, almonds are also rich in omega-3 fatty acids and also offer healthy doses of vitamin E for eye health. Vitamin E helps protect membranes of cells throughout the body against free radicals, including parts of the eye. Cataracts may be formed due to oxidation in the lens of the eye and Vitamin E offers preventative help.
Leafy Greens – Spinach, kale, collard greens and seaweed are rich in luteins, nicknamed the “eye vitamin” as it is incredibly important for eye health. When we consume foods rich in lutein it is deposited in high quantities in the retina. It helps to fight free radical damage caused by exposure to sunlight, reduces eye fatigue and light sensitivity, protects against the development of cataracts. and halts the growth of cancerous cells. Lutein can also be found in those brightly colored fruits and veggies mentioned above!
Eggs – Another great source of both lutein and Vitamin A to protect against night blindness, dry eyes and general eye health and function.
Legumes – Kidney beans, black-eyed peas and lentils are good sources of zinc which assists the body in absorption of Vitamin A and reduce one’s risk of macular degeneration.
