Cataract patients do not have absolute dietary taboos, can drink milk and milk powder, but not excessive consumption. Cataract is a common eye disease caused by clouding of the lens, there is no absolute food that can not be consumed, so patients can drink milk and milk powder, but it is not recommended to drink a lot of milk and milk powder. Because milk, milk powder contains lactose, can be broken down into galactose through the action of lactase, galactose can be deposited in the lens of the eye, thus triggering protein denaturation, reducing the transparency of the lens, aggravating the cataract condition. Cataract patients can consume more fruits and vegetables, drink more water, avoid eating fried food and spicy food, pay attention to the protection of the eyes in daily life, avoid the use of electronic devices for a long time, and at the same time pay attention to not strenuous exercise, work and rest, and pay attention to wear sunglasses and so on when you go out. It is recommended that cataract patients with obvious symptoms should consult the hospital in time to assess their condition and follow the doctor’s instructions for treatment.
