Pay attention to the following points in diet: 1. There must be meat and vegetables every day, preferably fungi and bean products. Eat marine fish every other day and seaweed (such as laver and kelp) at least once a week. 2, add a small amount of fruit between meals, about 200 grams each time. It is best to use raw vegetables such as strawberries, cucumbers, tomatoes and radishes instead of fruits. 3. The amount of vegetables and fruits eaten every day should not be less than 750g, and the edible oil should be controlled at about 20g.
