The doctor told us that apart from genetic factors, a person's height and weight seem to be twin sisters. If a person blindly pursues a slim figure, the result is often weight loss, which will also affect the growth of height. Therefore, the short nutrition of teenagers is mainly caused by human factors.
Due to the rapid growth of teenagers, the body's demand for energy and various nutrients has increased significantly. Teenagers should get heat energy from the food they eat every day, the amount is 10048 kj for boys and 9630 kj for girls. Among them, fat accounts for 30% of heat production, which is equivalent to eating 80 grams and 76 grams of fat every morning; Protein takes 80-90 grams a day; The intake of carbohydrates should be 500 ~ 600g per day, and of course a certain amount of vitamins and minerals should be taken. Students who exercise a lot should also increase the above nutrients. If you deliberately eat less or no foods with high fat and cholesterol in your daily basic diet, and at the same time you are unwilling to increase the intake of carbohydrates and protein, such as rice, noodles, cereals and eggs, meat, fish, etc. In the long run, not only the supply of heat energy is insufficient, but also the intake of protein and minerals will be reduced, which will be difficult to meet the needs of normal growth of the body and ultimately affect growth and development.
Of course, obesity caused by excessive intake is a malnutrition disease. Therefore, obese students need to do weight loss treatment. But weight loss treatment must be carried out under the guidance of a doctor. Because obese students are still in the growth stage, they can't ignore the relationship between height and weight gain like obese adults. If obese students only pursue weight loss, it means that heat energy can't make ends meet, which is called negative nitrogen balance in medicine. In this state for a long time, children may have growth stagnation. So simply losing weight is not the best policy. The ideal weight loss effect is: the weight does not increase, but the height increases, that is, in the process of weight loss, the height increases obviously, while the weight remains within the normal range. If the child's height grows too slowly in the process of losing weight, we should be alert to the possibility of nutritional dwarfism.
In order to avoid the nutritional dwarfism of teenagers, some suggestions are put forward:
First, establish a correct aesthetic view: modern human beauty is a tall figure based on strong and elastic muscles, rather than a "skinny" characterized by emaciation.
Second, popularize nutrition knowledge: Teenagers are in a period of growth and development, and proper nutrition is particularly important. In order to ensure the comprehensive nutrition of teenagers, parents should set an example, correct their bad habits of partial eclipse, picky eaters and anorexia, and make regular dietary adjustments under the guidance of doctors.
Third, change the way of life: Teenagers should appropriately reduce the sitting time and increase some more effective exercise.
