The annual winter vacation is coming, primary and secondary school students ushered in another happy vacation. Vacation, from the intense and heavy learning to liberate, the children can not help but sleep a lazy; Spring Festival, followed by adults visiting friends and relatives, the children can not help but big fish and meat, Sprite Coke to eat and drink a few times. In this way, the winter holidays a child may not be able to grow several pounds of meat, the school will increase a few small pudendum, small fat girl. Moreover, due to the children’s activities less, life is not regular, in the body fat at the same time the size is not see long. In case you eat some of the things that promote sexual development, but also accelerate epiphyseal closure, which is even more so that the child can not grow tall! What to do? How to let the children in the winter vacation can be happy to eat well, play well, rest well, but also be able to not gain weight, not early maturity, more tall? Here I suggest that parents and children to put a number of passes: First, put a good dietary pass Children in the growth and development stage, but also on New Year’s Day, do not eat or drink is not doable. The key is what to eat? According to the law of metabolism of nutrients, we eat into the sugar (carbohydrates) and fat is stored in the body into fat, while protein, vitamins, food fiber, minerals will not become fat. Therefore, if you want to avoid obesity or lose weight, you must eat less rice, pasta and other starchy foods, especially strict control of sweets (beverages, etc.), fried foods, fatty meats, cream, peanuts and walnuts and other high oil nuts. To eat more beef lean meat and other low-fat high-protein foods, green vegetables, bamboo shoots and other high-fiber foods. Special attention should be paid to the fact that many artificial aquatic products and animal foods fed with feeds supplied on the market nowadays contain food additives that will promote sexual development and should be used in limited quantities. For some children who have been obese can not rely on their own dietary control to lose weight, our school hospitals and ZJNU Nutrition Intervention Center cooperation to carry out a staple food substitution meal as the main means of intervention to lose weight project, small fat pier small fat girls may wish to use the winter holidays to try. Second, the good activity off In addition to controlling diet, strengthen the movement for weight control and promote the increase in height are also very important. Winter vacation children are relatively free, do not let the children day and night is not sleep is to play video games. Indulge in playing games of children too little activity, mental stress, will not only increase the accumulation of body fat, but also inhibit bone growth and growth hormone secretion, leading to obesity and growth deficiency. Children should be allowed to use the winter holidays to participate in basketball, jump rope, jump up to touch high (that is, draw a line on the wall or hang a ball or other objects in the high places, so that children continuously jump up to touch) and other “vertical activities”. Such a movement, not only will consume excess energy in the body, will also stimulate the development of bones, thus playing a role in weight loss, height. Third, put a good sleep off in the winter vacation if the child is inactive all day and night, eat and sleep, sleep and eat, will certainly bring an increase in body weight and body fat, or one month into a small fat pier or a small fat girl. But if you stay up late every night watching TV and playing games, it will lead to insufficient secretion of growth hormone in the body, slow bone growth, not conducive to the child’s growth. Because the human body secretes growth hormone peak is about 10:00 p.m. to 7:00 a.m. in the sleep process, so it is recommended that children must maintain a regular life, every night before 10:00 p.m. to bed, before 8:00 a.m. to get up. Before going to bed and after getting up to do some of the above mentioned “vertical movement”, will certainly promote physical growth. Maybe after the winter vacation can grow 1 to 2 centimeters! Fourth, the good medical care in the obese and short children in about 10 ~ 15% of the children are some disease factors, such as growth hormone deficiency, lack of vitamin D, micronutrient deficiencies, precocious puberty and so on. Overweight children also occur hypertension, hyperglycemia, hyperinsulinemia, lipid metabolism abnormalities. Therefore, parents are advised to take advantage of the winter vacation children relatively free opportunity to take them to the hospital to make some necessary checks. In conclusion, children’s weight loss, height increase, prevent precocious puberty is a systematic project closely related to lifestyle. Only from the diet, exercise, life rules and other aspects of the start, to put a good “control mouth, legs, early to bed, early check” this few off, in order to cultivate a tall, healthy children.
