Healthy Eating - Disease Prevention
No matter who is the father of your illness, the mother of it is unhealthy food.(Chinese saying)
Prevention of Macular Degeneration
With age, the macula, the central part of the retina, is exposed to changes under the influence of oxygen free radicals, generated by sunlight and other environmental factors. This can result in macilar degeneration, which leads to vision loss and even complete loss of sight - blindness.
Researchers from the University of Illinois in Chicago analyzed the diets of about 3,000 older Americans and found that only one carrot a day, or any other vegetable or fruit rich in beta-Carotene,
reduced the risk of macular degeneration (retinal) by 40%. This was compared with those who ate such vegetables or fruits less than once a week. Thus, one carrot a day can save you from loss of vision in old age. Vitamin C is another antioxidant that takes an active part in the prevention of vision loss in old age.
There is evidence that zinc deficiency is a cause of macular degeneration. Zinc is necessary for normal functioning of the retina. It activates an enzyme required for retinal rods. When this enzyme is reduced with age, probably due to zinc deficiency, retinal rods are degenerated, resulting in damage to the macula. In laboratory experiments, zink increased the activity of the enzyme by almost two times! In some cases, doctors prescribed doses of zinc that limited macular degeneration.
Oysters are champions in the content of zinc! A jar of smoked oysters contains a sufficient amount of zinc (90gr), to restrain macular degeneration. Besides oysters, other foods rich in zinc are pumpkin seeds, black rice, liver, sesame seeds and sunflower seeds.
For the prevention of macular degeneration and eye protection, eat fruits and vegetables containing beta-Carotene. It is included in vegetables and fruits such as carrots, pumpkin seeds, sweet potatoes, spinach, grapefruit, plums, peaches, melons, apricots and persimmons.
Also, remember about zinc!
