Research shows that cataracts are related to the lack of certain trace elements, vitamin B, vitamin C, and amino acids. Therefore, we should eat more vegetables, fruits, fish, meat, and animal organs that contain the above substances in our diet. The diet should be light, avoiding greasy, heavily salted foods and strong spices. At the same time, smoking and alcohol should be avoided to cultivate good eating habits and maintain balanced nutrition. Additionally, it is important to rest and boost one's immunity, which are beneficial for preventing cataracts and inhibiting their progression.
