1, don't eat too much cold drinks for a long time, which is harmful to your health: in summer, many children love to eat ice cream. If children eat too much at a time, it is very harmful to their health. In summer, the secretion of gastric acid in human body decreases, and the immune function of digestive system declines, while the climatic conditions at this time are just suitable for the growth and reproduction of bacteria. Therefore, summer is the season of digestive tract diseases. Eating too much cold drinks will cause sudden drop in the temperature in the gastrointestinal tract of children, slow down local blood circulation and other symptoms, affect the absorption and digestion of nutrients in food, and may even lead to digestive dysfunction, nutritional deficiency and frequent abdominal pain in children.
2. Drink more boiled water: Drinking boiled water can not only meet children's physiological needs for water, but also provide them with some minerals and trace elements. Whether it is carbonated drinks, nutritious health drinks, or pure water and mineral water that many families are keen on at present, it is not suitable to replace tap water as the main drinking water for people. When the boiled tap water is cooled to 25~35 degrees Celsius, the biological activity of water increases, which is most suitable for human physiological needs.
3. Eat puffed food as little as possible, or don't eat it: fried potato chips, snow cakes, potato chips, shrimp strips, shrimp slices, chicken wai, chicken strips, corn cob ... are children's favorite puffed food. Long-term consumption of puffed food will lead to high intake of oil and heat and insufficient intake of crude fiber. If you don't exercise enough, it will cause fat accumulation and obesity. Children often eat puffed food, which will affect the normal diet, lead to a variety of nutrients can not be guaranteed and supplied, prone to malnutrition. Puffed food is generally high in salt and monosodium glutamate, which will easily lead to hypertension and cardiovascular disease in children's adulthood.
4. Eating too much jelly will hinder the absorption of nutrients: most of the jellies sold in the market are not made of fruits, but are made of thickeners such as sodium alginate, agar, gelatin and carrageenan, and a small amount of synthetic flavors, artificial colorants, sweeteners and sour agents. Although sodium alginate and agar are dietary fibers, excessive absorption will affect the absorption of fat and protein, especially inorganic salts such as iron and zinc will be combined into soluble or insoluble mixtures, thus affecting the absorption and utilization of these trace elements by the body.
5. Children should not drink more cola and coffee: A large number of studies have found that drinking coffee and caffeinated drinks often is not good for children's health. Caffeine is actually a stimulant, which mainly acts on the central nervous system, stimulating heart muscle contraction, accelerating heartbeat and breathing. Caffeine is irritating, which can stimulate gastric peristalsis and gastric acid secretion, causing intestinal spasm. Children who often drink coffee are prone to unexplained abdominal pain, and long-term excessive intake of caffeine will lead to chronic gastritis. Caffeine can dilate the capillaries on the gastrointestinal wall, and children's bone development will also be affected. At the same time, caffeine can also destroy vitamin B 1 in children, causing vitamin B 1 deficiency.
