Core Tip: Experts believe that vitamins and some trace elements play a significant role in preventing and treating the formation and development of cataracts. Therefore, the elderly should regularly consume foods rich in Vitamin C, Vitamin E, beta-carotene, glutathione, Vitamin B1, Vitamin B2, and other vitamins.
Cataracts, one of the common diseases in the elderly, increasingly pose a threat to their health. Cataracts refer to a condition where the lens of the eye becomes cloudy, leading to blurred vision.
In recent years, many researchers, through extensive laboratory studies, have suggested that cataracts may be the result of multiple factors, with oxidative damage to the lens being the primary cause. Studies have found that the lens itself has certain functions to defend against oxidative damage. For instance, the presence of some scavengers and other organic substances in the lens can clear certain intermediate products of specific reactions, protecting the lens from damage. The main ones include Vitamin C, Vitamin E, beta-carotene, glutathione, Vitamin B1, and Vitamin B2.
Furthermore, various trace elements and minerals are also involved in the metabolism of lens proteins. Once these vitamins and related components are deficient, metabolic disorders occur, oxidized protein components increase, and the lens gradually becomes cloudy, forming a cataract.
Experts believe that vitamins and some trace elements play a crucial role in preventing and treating the formation and development of cataracts. Therefore, the elderly should regularly consume foods rich in Vitamin C, Vitamin E, beta-carotene, glutathione, Vitamin B1, Vitamin B2, and other vitamins.
Therefore, to prevent cataracts, the elderly should also supplement their diet with additional vitamin nutritional supplements to meet their daily nutritional needs and prevent disease.
