Consuming foods rich in antioxidants can promote eye health. Antioxidants help defend the body against cell damage caused by free radicals. Free radicals are unstable oxygen molecules mutated by exposure to pollution, the sun’s rays and other environmental conditions. These free radicals seek out and attach themselves to various cells in the body and in doing so, change the cell composition.
When this happens, the cells and DNA are damaged. This leads to mutations that can lead to many different conditions such as heart disease and macular degeneration. Some scientists belive that free radicals cause the aging process in humans and macular degeneration is more common in the aging population. It has therefore been speculated that free radicals may lead to the development of age-related macular degeneration.
Foods rich in antioxidants such as broccoli, tomatoes, berries and spinach cause antioxidants to be formed and flood the bloodstream. These provide defence against free radicals. Diets rich in vitamin c, E and beta-carotene are strong defenders against heart disease, cancer and eye disease.
Studies have shown that vitamin C, E and beta-carotene are well known antioxidants and minerals such as zinc and selenium are also powerful antioxidants and that these have been shown to promote good eye health and slow the progression of macular degeneration.
Doctors recommend that most antioxidants should be taken through dietary consumption rather than through nutritional supplements. Eating five to six portions of fruits and vegetables daily will supply the body with its daily requiremetns of vitamins and antioxidants.
Eating a healthy diet rich in antioxidants will promote eye health. It is important to be aware of the foods being consumed and the benefits that antioxidants can have on reducing the risks associated with eye disease.
