Winter vacation is coming, primary and secondary school students from the intense and heavy learning to liberate, inevitably sleep a lazy; New Year’s Day, followed by adults visiting friends and relatives, it is inevitable that big fish and meat, Sprite Coke to eat and drink. In this way, the winter holidays, the child may not be able to grow several pounds of meat, the school will increase a few small pudendum, small fat girl. Due to the children’s activities less, life is not regular, the body becomes fat at the same time, but not see the growth of the size. In case you eat something to promote sexual development, will also accelerate epiphyseal closure, which is even more so that the child can not grow tall! How can the children in the winter vacation can eat well, play well, rest well, but also not to gain weight, not early maturity, more tall? Parents and children in the winter vacation to put a number of passes: First, a good diet pass. Children in the stage of growth and development, but also the New Year’s holidays, 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 will be 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 to strictly control sweets (beverages, etc.), fried foods, fatty meats, cream, peanuts and walnuts and other high oily nuts, and to eat more low-fat, high-protein foods such as lean beef, green vegetables, bamboo shoots and other high-fiber foods. In particular, we should remind you that some artificial aquaculture aquatic products and animals supplied on the market nowadays contain food additives that will promote sexual development in their feeds, which should be used in limited quantities. Secondly, keep a good activity level. In addition to controlling diet, strengthening exercise is also important for controlling weight and promoting height gain. Winter vacation children are relatively free, must not every day either sleep or 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 movement, not only will consume excess energy, will also stimulate the development of bones, thus playing a role in weight loss, height. Third, good sleep. If the child is inactive all day and night, eat and sleep, sleep and eat, will certainly bring about an increase in body weight and body fat, it may not become a month a little fat pier or a little fat girl. 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 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, 10:00 p.m. every day before going to bed, 8:00 a.m. before getting up. Before going to bed and get up to do some of the above mentioned “vertical movement”, will be able to promote the growth of the body, maybe after the winter holidays can grow 1 to 2 centimeters it! Fourth, the good doctor. In the obesity and short children about 10% to 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 will also occur hypertension, hyperglycemia, hyperinsulinemia, lipid metabolism abnormalities. Therefore, parents are advised to take advantage of the relatively free time of their children during the winter vacation to take them to the hospital for some necessary examinations.
