Abstract: medical scientists have observed and contrasted a lot of people. The elderly who drank 5 cups of tea a day had no chance of developing cataracts. Tea or tea drinking habits were much lower in the elderly. Incidence rate of cataract was lower in those aged than those who drank some tea and never drank tea. Scholars believe that this is related to tea, which contains a lot of tannic acid and., What should be paid attention to in the diet of cataract are:
what should be paid attention to in the diet of cataract are:
. First, supplement trace elements: cataract patients should pay special attention to selenium, which is directly related to the visual acuity. Selenium deficiency can cause cataract lens opacity, which proves that scientists. Selenium rich foods include animal liver, kidney, heart, fish, milk, eggs, meat, mushrooms, fungus, sesame, etc. The study found that serum zinc level and incidence rate of cataract were lower, serum zinc level was lower, incidence rate of cataract was higher. Animal foods, oysters, fish, lean meat, animal liver, kidney, eggs and dairy products have high zinc content, including the highest zinc content in oysters, with zinc content of up to 14 mg per 100 grams of oysters. Second, take enough vitamins: how do cataract patients pay attention to health care? Scientists have found that vitamin C has the effect of preventing cataract. It can reduce the damage of light and oxygen to the lens. If you take insufficient vitamins, it is easy to cause lens degeneration. Therefore, the elderly should eat more vitamins, tomatoes, spinach, onions, cabbage, beans and other fresh vegetables and strawberries, oranges, grapefruit, oranges and other fruits. In addition, scientists say that low blood ve levels can induce cataracts. Because the decrease of vitamins can increase the oxidation reaction, it is easy to make protein crystals aggregate into muddy. Three, drink more tea: medical scientists have observed and contrasted in large quantities that the incidence rate of cataracts is not that much tea or tea drinking habits are much lower in elderly people than those who drink 5 cups of tea a day. Scholars believe that this is related to tea, which contains a lot of tannic acid and.
