Because you still have at least seven or eight years to grow and develop. (2) The influence of heredity on height is about seven or eight centimeters, and your nutrition and exercise conditions are much better than your parents at that time. (3) Exercise can increase the intake of nutrients (generally speaking, it can increase food intake), which is conducive to the increase of height. Therefore, proper exercise is still necessary, regardless of form and time. The key to the problem is how to supplement adequate nutrition! Height is basically determined by the growth and development of bone tissue. Therefore, how to supplement the nutrition of bone tissue may be more important. In human skeletal tissue, except for 30% calcium and 16% phosphorus (both of which account for almost 50%), the rest are almost all collagen and water. Therefore, supplementing calcium, phosphorus and collagen can effectively promote the growth and development of bone tissue! It is meaningless to simply supplement calcium. It's like building a house. If only cement is used, can this house be built? In addition, although some people say that the current diet is not low in phosphorus, it seems that there will be no shortage of phosphorus. But I think that almost all the phosphorus in plants exists in the form of phytate phosphorus, and phytase is also lacking in human body for decomposition, so the absorption and utilization rate of these phosphorus by human body is not high. It is good to drink bone soup, and you can boil out some collagen, but there is not much dissolved calcium and phosphorus. If you can grind the bone into fine powder and take it best, you can "achieve" the nutrients needed for bone growth and development at the same time and effectively synthesize human bone tissue. If you like fish, you'd better eat it fried or grilled, and eat it with fish and bones. This is not only economical and practical, but also has no toxic and side effects, which conforms to the basic principle of health preservation that medicine tonic is not as good as food tonic.
