First of all, you must eat three meals. In the morning, protein is the main food, so you don't have to be full. It is best to eat milk with eggs or bread in the morning, but milk can't be cooked with eggs, otherwise it will produce calcium oxalate. Milk should not be drunk on an empty stomach, otherwise it will react with stomach acid. If you can't drink milk, you should drink soybean milk, but you can't drink soybean milk on an empty stomach because protein will be converted into heat by the human body on an empty stomach, which can't achieve the purpose of supplementation. Soymilk without brown sugar will destroy nutrients, and it can't be put in a thermos, which will speed up the shelf life of soybean milk and easily lose nutrients. There are still many matters needing attention here. Half an hour to an hour before lunch, it is recommended to eat a small amount of fruit to enhance immunity, eat eight full lunches, and eat a variety of foods, including red, yellow, black, green and white. It is recommended to eat carrots and potatoes frequently. Carrots have a lot of carotene that can be converted into vitamin A, while potatoes are very rich in nutrition, which almost meets all the nutrients needed by the human body. They also contain eight essential amino acids, especially vitamin C. Milk and potatoes can maintain a person's life. However, it should be noted that carotene will interfere with the absorption of vitamin C, so don't eat it together. Foods with high vitamin C content include cucumbers, tomatoes, white radishes, peppers and so on. Eat less for dinner. Traditional Chinese medicine holds that people should not eat at night and it is normal to be hungry at night. In fact, eating two apples at night is enough. The second is to pay attention to taste. Generally speaking, it is light, and the daily salt intake should not exceed 5 g, about two beer lids, and it should not exceed 3 g for special patients. In addition, we should eat less meat. Although protein in meat is high, it is also high in fat, while people need a lot of protein but a little fat, so we should eat more fish with high protein and low fat. In a word, the more legs, the less nutrition. Four-legged animals are not as good as two-legged birds, two-legged birds are not as good as one-legged fungi, and one-legged fungi are not as good as fish without legs.
