Cataract patients should pay attention to what? Wang Yi, director of ophthalmology at Shanghai Renai Hospital, said that cataract patients can drink more tea and tea can prevent cataracts. In addition, eating more foods rich in vitamin C also has an inhibitory effect on the formation of cataracts.
Careful attention for cataract patients is as follows:
Changyin Tea
Tea contains a tannic acid, has an antioxidant reaction. The occurrence of cataract is caused by the free radicals produced by the oxidation reaction in the body. Therefore, regular tea drinking can prevent the occurrence of cataract. Some people have studied that drinking 5 cups of tea a day has a good effect on preventing the occurrence and development of cataracts.
Eat more foods rich in vitamin C
Scientific research has found that vitamin C has the effect of preventing cataract formation. Because the formation of cataracts is the result of long-term effects of light and oxygen on the lens, and vitamin C can weaken the damage of the lens and oxygen to the lens, which can prevent the occurrence and development of cataracts. To this end, middle-aged and elderly people suffering from cataracts should appropriately eat more foods rich in vitamin C, such as tomatoes, jujube, prickly pear, and fresh green vegetables and so on.
Eat more zinc-rich foods
According to studies, the content of zinc in the lens is high, and the amount of zinc in the lens of people suffering from cataract is significantly reduced. Therefore, zinc deficiency will promote the formation of cataracts, so people with cataracts should eat more zinc-rich foods such as herring, sardines, lean meat, peanuts, walnuts, oysters and so on.
Eat more foods rich in selenium
Scientific research has found that when selenium content in the body is insufficient, the activity of glutathione hydrogenase in the lens can be significantly reduced, and the incidence of cataract can be significantly improved. Therefore, the prevention of cataracts should be appropriate to eat more foods rich in selenium, such as asparagus, mushrooms, grains, fish, shrimp and so on.
Eat less cholesterol-rich foods
According to scholars' research, patients with cataract have higher levels of cholesterol in their lenses. They believe that the occurrence of cataracts has a certain relationship with cholesterol. Therefore, foods with high cholesterol, such as egg yolk, squid, and viscera should be properly controlled. .
