Dr. James McDonnell, a specialist from the Loyola University Chicago, has set up a list of aliments which can maintain a healthy eye function.
He recommends people to increase the level of broccoli, blueberries and sardines in their diet.
According to Dr. McDonnell, several nutrients are crucial to eye health, and some of them could help to improve eyesight and prevent health problems, such as macular degeneration or cataracts. The pediatric ophthalmologist at the Loyola University Health System has composed a list of these nutrients, but also with the foods that are rich in them.
The lists starts with Omega-3. The extraordinary fatty acid offers protection from macular degeneration. It is found in oliy fish, like mackerel or sardines, but also in canola oil.
Dr. McDonnell recommends astaxanthin, a pigment which also acts as powerful antioxidant. It can prevent the development of cataracts. In order to get it into your system, you must eat seaweed and wild salmon. The experts says you must eat more blueberries and blackcurrants in order to raise your level of anthocyanins, a series of pigments, that range in color from red to blue and help to keep the cornea healthy. They also take care of the blood vessels in the eye.
Vitamind D, which can be acquired just by standing in the sun for a few minutes or eating fish, egg yolks or liver, is also on the list, as is beta-carotene, a compound usually found in carrots, butternut squash and sweet potatoes. This substances keep the eye safe, reducing retinal inflammation and even improving vision. Eating more carrots and gaining its important provitamin will help you to prevent dry eyes, but also to improve night vision.
The expert from Loyola University Chicago also has lutein on his list, a substance which can be easily found in organic eggs. It also prevents macular degeneration.
Zeaxanthin, which is found in dark leafy green vegetables, will reduce age-related problems to your eyes. In order to get it, you must eat vegetables such as broccoli, spinach kale and collard greens. This nutrient may also help reduce the risk of macular degeneration.
Antioxidants like bioflavonoids, which belong to the polyphenols family, can cut the risk of cataracts and macular degeneration. All you need to do in order to increse their levels in your body is to eat cherries, citrus fruits, drink tea and even red wine.
