Diet: Many parents of short children often think that their children are short because they usually eat too little or are too picky about their food. Instead, over-nutrition is common. Over-nutrition is one of the main reasons why the incidence of precocious puberty is increasing year by year. Children who are short in stature need less than other children because of their slow growth, and most do not eat much. From time to time, we also find that children who were eating smaller amounts of food grow significantly if they develop puberty, for this reason. Whether it is short or precocious children, in terms of diet, it is better to have a balanced diet, that is, a reasonable mix of meat and vegetarian dishes, and a balanced intake of coarse and fine grains. Many parents, the first thing they think of when it comes to short children is that they are undernourished and eat less (most of the appetite of short people is really bad due to their slow growth and relatively low nutritional needs), or they think they are “late growing” (even if they have already developed early, they still blindly think they are late growing, in fact, children now generally develop earlier than the previous generation). For thousands of years, the vast majority of the country’s people have long been underfed, and the most common greeting when they meet is “Have you eaten?” The concept of supplementation is deeply rooted. In recent decades, the domestic economy has grown too fast, and now you can eat anything you want, so excess nutrition is becoming more and more common. Over-enhance nutrition, there will certainly be some will pay a heavy price for some! Many adult diseases, such as obesity, hypertension, diabetes, heart and cerebrovascular diseases, etc., may be related to over-nutrition in childhood. Overall, overnutrition is more common among children in China today. Many parents, especially the elderly, because they did not eat well in the past, now do everything possible to make their children eat more and better, always worried about the lack of nutrition in the formative years, and even find ways to supplement various health products, trace elements or vitamins, this idea is obviously wrong. Those who have been to Japan may know that Japanese adults often have only six or seven sushi for Chinese food, and Chinese students often do not have enough to eat when they first go there. However, the Japanese do not suffer from malnutrition, but rather their average height is already higher than that of the Chinese, and the proportion of obesity is significantly lower than in other developed countries. Thus, the total amount of food, the amount of non-vegetarian dishes and unhealthy foods need to be appropriately limited. However, it is also not good for some parents to restrict their children’s diet excessively after discovering precocious puberty. Since they are growing children, basic nutrients still need to be ensured. It is recommended to be able to stick to 1~2 bags of milk and 1 egg per day (regardless of the cooking method and whether it is consumed alone or by adding it to dishes or soup, as long as it is cooked), while other meat dishes need to be appropriately limited. Although milk and eggs are not guaranteed to be safe, too much restriction is certainly not beneficial. For some of the fatter children, it is best to eat some fruit or soup before eating and to slow down the pace of eating. Although this is not a very reasonable way to eat. Because, our feeling of stomach fullness and hunger is not felt by the empty or full stomach, but by the high or low blood sugar. When the blood sugar is low, the stomach feels empty. If you eat too fast, although you have reached the normal serving size, but because blood sugar has not yet come to rise sharply to the normal level, you will also feel that you have not eaten enough, you will eat more. Due to various advertising campaigns and other reasons, there are also often parents who believe that their children will be deficient in zinc, calcium and so on. In fact, except for the need for proper vitamin D supplementation during infancy to prevent calcium deficiency, a normal diet will not cause micronutrient deficiency. Moreover, since it is a micronutrient, more is not better! Too much can cause other harmful effects. I often give parents the analogy: “An egg, without any external factors, can hatch chicks, but if the nutrients needed for life are missing, the chicks will not hatch”. Other foods are also composed of cells and have various nutrients, but the content and ratio of various nutrients vary from food to food. Please remember: medicine is better than food! Humans cannot synthesize their own proteins, and no health food is comparable to natural food! For the prevention of precocious puberty, some foods should be eaten as little as possible, such as too much animal foods, fresh borrows (14), frightened (13) and frightened. The first thing you need to do is to take a look at the pills and let your child eat them. Excessive application of cosmetics is also not good, and it is not good for the mother to kiss her child with too much cosmetics. Sleep: As growth hormone is the most important hormone for human growth, the secretion of growth hormone is mainly secreted during deep sleep. Therefore, it is also important to ensure a more adequate sleep. School-age children generally need 8 to 9 hours of sleep a day. It is better to go to sleep earlier, but it is not necessary to emphasize the early or late sleep, as some people understand that growth hormone is only secreted at what time of the day, but only in relation to the depth and total time of sleep. Modern people go to sleep later than in the past, but not for shorter, but because of improved nutrition, timely and effective control of diseases, etc. Exercise: Since exercise is also a way to promote the secretion of growth hormone, proper exercise is good for growth, regardless of treatment. Exercise that is beneficial to growth is aerobic exercise. The definition of aerobic exercise is: ① medium intensity (too much exercise intensity, too little is not good, just stop when the heartbeat in 120 ~ 150 times / min more appropriate), ② regular, continuous exercise, ③ at least 20 minutes each time (for those who need to lose weight, it is best to reach half an hour each time), ④ as much as possible in the outdoors (everything grows by the sun, human growth is the same. The reason why people in the north are taller than the south, there are climatic factors, but also the sunshine time factor. (The more northern, the less rain in a long year, the longer the total time of sunshine). The way to exercise to jogging, slow jump rope, etc. is good. Ball sports, swimming, etc. can also be, only need to pay attention to maintain the continuity of the movement, the ball is not in the hand also need to pay attention to run. Too strenuous exercise will cause hypoxia, is anaerobic exercise, but not conducive to growth. There is also a disadvantage to exercising for too long a continuous period of time. Other aspects: Children aged 2 to 14 years generally need to be dewormed twice a year for intestinal parasites, it is not necessary to find out that there are eggs before deworming is needed, as long as it is done when they are not sick. Usually, if you are sick, try to go to a regular hospital in time. Some drugs such as adrenocorticotropic hormones and quinolone antibacterial drugs have a height-suppressing effect. Conclusion: Although proper diet, sleep and exercise are good for growth, do not be too superstitious about these aspects without treating related diseases. If you are found to have a disease related to short stature or precocious growth, treatment is a must. Our adult height prediction includes having a normal diet, sleep, and exercise, and is predicated on having a serious disease, so you can’t enhance exercise, etc. without treating the related disease!
