Proper nutrition not only benefits the overall health, but also extends to eye health, especially as we age. You can also consume certain vitamins and nutrients, according to numerous investigations, nourish and protect the integrity of the eyes. Here is a summary of those findings.
The fruits may reduce the risk of progressive macular degeneration (AMD, for its acronym in English). A study by the Channing Laboratory of Harvard Medical School, indicates that people who consume a daily diet with several servings of fruits may reduce the risk of developing AMD in old age. The study compared the intake of antioxidant vitamins and carotenoids (as beta carotene) as well as fruits and vegetables among the elderly participants and found that those who ate three or more servings of fruit per day over a period of 12 to 18 years , reduced the risk of suffering from progressive macular degeneration by more than 30 percent, compared with those who consume 1.5 servings daily or less often.
Vitamin A reduces night blindness. A diet lacking in vitamin A can lead to night blindness, deterioration of light-sensitive cells (rods) essential for vision at low illumination. This deficiency can also cause extensive damage to the cornea and can cause total blindness. A study conducted by Dr. Alfred Sommer, an ophthalmologist, found a link to the inadequacy of vitamin A (retinol) with the high prevalence of night blindness in children in developing countries like India and Bangladesh. Sommer found that night blindness decreased by one third in children who were given vitamin A. Sources rich in this vitamin include: cod liver oil, liver, carrots, sweet potatoes and pumpkin. (Note: Although vitamin supplements may be beneficial, can be toxic if consumed in extremely high doses. Everything in moderation. It is not now gorging on a particular vitamin but eating a balanced and steady. )
For its part, vitamins E and C slows the progression of cataracts. Sources of vitamin E include: sunflower seeds, almonds, walnuts, hazelnuts, pistachios, avocados, peanuts and nut products such as oils and butters, eggs (one egg provides about 6 percent of the recommended daily allowance of vitamin E), vegetables, tomatoes, asparagus and sweet potatoes. Also, good sources of vitamin C are fruits such as guava, oranges, grapefruits, melons, grapes and fruit juices, and vegetables like peppers, cabbage, potatoes, broccoli, onions, tomatoes and pumpkins, and meats like liver and viscera , plus some seafood.
