The eye is the only part of the human body that can function at 100 per cent ability at any moment, day or night, without rest. The eyelids need rest, but the eyes don’t!
- Everybody’s heard of the old belief that eating carrots can help you see in the dark. That may or may not be true, but a rapidly growing body of evidence indicates that eating certain foods can indeed help to safeguard your vision and conversely certain foods can increase the risk of vision deterioration.
- The most important nutrients essential to eye health are vitamins A, C and E, the anti¬oxidants lutein and zeaxantin, some essential fatty acids and microelement zinc. An adequate intake of these nutrients lowers the risk of eye disease, maintain acuity of vision, protect the eye-tissue cells from damage by freeradicals and ensure the proper function of the eye.
- Vitamin A is found in egg yolk, wholemilk, turnip greens, drumsticks, beets, carrots, spinach, mangoes, apricots, raspberries; vitamin C in Indian gooseberries (amla) guava, limes, oranges, papayas, potatoes; vitamin E in vegetable oils, eggs, butter; zinc in cereals, nuts and oilseeds and copper in barley, walnuts, cashewnuts, whole lentils; all these are important for the eyes.
- Generally speaking there are no foods bad for eyesight. A 2006 study by the Jean Meyer US Department of Agriculture (USDA) Human Nutrition Research Centre on Ageing found that certain high glycemic food like quickly digestable carbohydrates, candies etc. over a long period of time can damage the eye.
