1) Eat more foods rich in protein. Children are in a stage of rapid physical development. Both the proliferation of bone cells and the development of muscle organs are inseparable from protein. Therefore, children are malnourished. They should supplement protein, eat more milk, lean fish and shrimp bean products and other foods rich in protein, lecithin and lysine, which is beneficial to the development of the brain and the growth of the body.

(2) Eat more foods rich in vitamins. Vitamins are essential for maintaining life, and the most important one is vitamin abcd, which is essential for children's growth and development.

The best source of vitamins is fresh fruits and vegetables. Although animals' liver and eggs contain vitamins, they are only a small amount, so children with malnutrition should eat more fresh fruits and vegetables.

(3) Eat more foods rich in calcium and phosphorus. Calcium and phosphorus trace elements are the main components of bones and have an important impact on physical development. Therefore, children with malnutrition should eat more milk, bean products, ribs and bone soup, kelp, seaweed, sesame and other foods.

In addition, we should bask in the sun more and increase the chances of ultraviolet radiation, so as to ensure the healthy growth of bones.
