With the arrival of winter vacation, many parents' "sweet troubles" also come along. Children don't have to wake up early, their three meals and daily routines are disrupted, outdoor activity time is sharply reduced, they keep watching TV dramas and games, and unknowingly, their "little belly" quietly emerges. How to avoid becoming a "chubby kid" during holidays? The Beijing Center for Disease Control and Prevention reminds that during the winter vacation, the "energy intake" and "energy expenditure" of some primary and secondary school students are seriously imbalanced. Parents must help their children develop healthy eating and exercise habits. Li Ting, the chief physician of the School of Health at the Beijing Center for Disease Control and Prevention, said that it is easy to gain weight during winter vacation because the body has activated a "heat storage mode" under the dual influence of "environment+habits". On the one hand, as the Spring Festival approaches, family gatherings and snacks are becoming more common, and high oil and high sugar foods are readily available, making it easy for children to unknowingly overeat; On the other hand, the cold winter weather reduces outdoor activities, and with the attraction of electronic devices, children may sit for up to 6 to 8 hours a day, consuming half of their calories less than when they were in school. The excess calories will be converted into fat and accumulated in the body. Children and adolescents are in a critical period of growth and development, and 'dieting' is definitely a big taboo. For primary and secondary school students who are growing their bodies, the key is to 'eat right' rather than 'eat less'. ”Li Ting said that the dining table can be turned into a "color palette" to encourage children to actively fall in love with healthy food. Different colored foods are rich in vitamins and dietary fiber, which can increase satiety and reduce the intake of high-fat and high sugar foods. The visual richness can also enhance the happiness of eating. Parents can divide snacks with their children into "daily", "occasional", and "try not to eat". Fresh fruits, original nuts, sugar free yogurt, cucumbers, tomatoes and other foods are rich in nutrients and have a strong sense of satiety. They can be placed in a prominent place in the living room, and children can take them whenever they are hungry; Potato chips, cookies, and chocolate should be eaten at most 1 to 2 times a week, with a small portion each time, and should be eaten after meals to avoid eating too much on an empty stomach; Sugary drinks, fried foods, and candies are high in calories and poor in nutrition. Parents should control their purchases and try not to eat them. Experts say that many children do not like sports because they find "running and skipping rope too boring". During winter vacation, parents can turn exercise into a 'parent-child game', allowing their children to burn calories while playing, which not only enhances relationships but also prevents obesity. Daily household chores and travel can also burn calories, encourage children to walk more and do more housework. Irregular sleep patterns can also lead to weight gain. ”Li Ting said that preventing obesity during winter vacation is not about "limiting" children's happiness, but about using innovative and interesting ways to help children develop healthy eating and exercise habits. It is recommended that parents and children develop a "winter vacation schedule" together to avoid staying up late and sleeping in. The companionship and guidance of parents are the most important. Regular sleep can keep the body's metabolism stable and reduce the risk of fat accumulation. (New Society)
