Eat less and eat more, but don't increase the amount of food per meal. Because most thin people have weak gastrointestinal function, eating too much at a meal often cannot be effectively absorbed, but it will increase the burden on the stomach and cause indigestion. You can change the number of meals per day to 4~5 times. Food is based on the principle of high digestibility, high protein and high calorie, and gradually increases the intake of various nutrients, such as chicken, fish fillets, vegetables, sea cucumbers, butter and cream.

1, eat more foods rich in protein.

Children are in the stage of rapid physical development. Whether it is the proliferation of bone cells or the development of muscles and organs, protein is indispensable. Therefore, children with malnutrition should be supplemented with protein. Eating more foods rich in protein, lecithin and lysine, such as milk, peanuts, lean meat, fish and shrimp, eggs and bean products, is beneficial to the development of brain and body.

2. Eat more foods rich in vitamins.

Vitamins are vital elements, among which vitamins A, B, C and D are the most important, which are very important for children's growth and development. The best sources of vitamins are fresh fruits and vegetables. Although animals' livers, kidneys and eggs contain vitamins, the quantity is very small. Therefore, malnourished children should eat more fresh fruits and vegetables.

3. Eat more foods rich in calcium and phosphorus.

Trace elements calcium and phosphorus are the main components of bones and have an important influence on physical development. Therefore, malnourished children should eat more milk, shrimp skin, bean products, ribs, bone soup, kelp, laver, sesame and other foods. In addition, bask in the sun more and increase the chances of ultraviolet radiation, thus ensuring the healthy growth of bones.
