What to eat for cataract 1.Food science has found that vitamin C can prevent cataract formation.Because the formation of cataract is due to the long-term effect of light and oxygen on the lens, and vitamin C can reduce the damage of light and oxygen to the lens, thus preventing the occurrence and development of cataract.For this reason, we should eat more food rich in vitamin C, such as tomatoes, dates, Rosa roxburghii, fresh green vegetables and so on. 2.Eating more zinc-rich foods, according to research, has a higher zinc content in the lens, while the zinc content in the lens of cataract patients is significantly reduced.Therefore, zinc deficiency can promote the formation of cataract, so people with cataract should eat more zinc rich foods, such as black carp, sardines, lean meat, peanuts, walnuts, oysters and so on. 3.Eating more selenium-rich food sciences have found that when the 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 increased.Therefore, we should eat more selenium-rich foods, such as asparagus, mushrooms, grains, fish, shrimp and so on. 4.Tea often drinks contains a tannic acid substance, which has antioxidant effect.The occurrence of cataract is caused by the free radicals produced by the oxidation reaction in the body acting on the lens, so drinking tea regularly can prevent the occurrence of cataract.Some people have studied that drinking five cups of tea a day has a good effect on preventing the occurrence and development of cataracts.
