The height problem of junior one boys.
13 years old, normal height 1.64. If you don't want to grow taller at all, you should eat more protein, especially foods containing amino acids, such as flour, wheat germ, beans, shrimp, crab, shellfish, laver, beef, chicken, liver, pork leg, eggs, milk and pork.

On the contrary, white rice, glutinous rice, desserts and other foods should be avoided as much as possible. It is better to eat less cola and fruit juice, because it contains more sugar, which will hinder the absorption of calcium, and eating too much will affect the development of bones. In addition, salt is also the enemy of increase, so we must form the habit of eating less salt. Take part in physical exercise. Regular physical exercise suitable for growing tall and strengthening the brain can promote blood circulation, ensure adequate nutrition of skeletal muscle and brain cells, promote bone thickening and bone density thickening, and strengthen the ability to resist compression and bending. Exercise can promote the secretion of growth hormone and make bones, muscles and brains develop better. Therefore, we should take part in more activities suitable for growing tall and strengthening the brain, such as skipping rope, kicking shuttlecock, bungee jumping, rhythmic gymnastics and various ball games. And we can also ensure adequate sleep and achieve the best effect of increasing height by increasing the organic combination of adjuvant therapy and exercise. Sleep is also a "nutrient" that makes the human body grow taller. As the saying goes: people grow up in sleep. Because sleep can not only eliminate fatigue, but also after the human body falls asleep, the secretion of growth hormone is stronger and lasts longer than usual, which is conducive to growth and height. Therefore, develop regular living habits and ensure adequate sleep. Increase minerals. The height of human body depends on the growth and development of bones, among which the growth of long bones of lower limbs is most closely related to height. In other words, only the epiphyseal chondrocytes in long bones keep growing can the human body grow taller. Calcium and phosphorus are the main components of bones. Therefore, milk, shrimp skin, bean products, ribs, bone soup, kelp, seaweed and other foods rich in calcium and phosphorus should be supplemented in May and June. In addition, we should go outdoors to bask in the sun and increase the chances of ultraviolet radiation, so as to facilitate the synthesis of vitamin D in the body and promote the absorption of calcium and phosphorus in the gastrointestinal tract, thus ensuring the healthy growth of bones and supplementing vitamins and cellulose. Vitamins are vital elements, among which vitamins A, B and C are the most important and necessary for human growth and development. Animals' livers, kidneys and eggs, especially vegetables, contain many vitamins, cellulose and minerals, so we should eat more fresh vegetables.
