Carbonated drinks (coke, sprite, Fanta, etc. ) Coke contains more phosphorus and a certain amount of caffeine, which is harmful to human body. As for Sprite and Fanta, some artificial pigments are usually put in, which is not good for human body. The three ingredients of carbonated drinks affect health and digestion. Although carbonated drinks have diverse tastes, the main ingredient is carbon dioxide, so it will feel refreshing and exciting to drink. Some people say that carbonated drinks contain carbon dioxide, which may be bad for people. Professor Wang Lixin said that enough carbon dioxide can actually play the role of sterilization and bacteriostasis in drinks, and it can also take away the heat in the body through evaporation and play a role in cooling down. But drinking too much carbonated drinks is not good for the stomach, and it will also affect digestion. Because a large amount of carbon dioxide can inhibit bacteria in drinks and beneficial bacteria in the human body, the digestive system will be destroyed. Young people especially like the stimulation brought by drinking soda and steam, but if they drink too much at once, the released carbon dioxide can easily cause abdominal distension, affect appetite and even cause gastrointestinal dysfunction. A lot of sugar is harmful to the health of teeth. Besides containing refreshing and stimulating carbon dioxide vapor, the sweetness of carbonated drinks is also an important reason to attract people to drink. This thick sweetness comes from sweeteners, that is, drinks contain too much sugar. Too much sugar in the beverage is absorbed by the human body, which will produce a lot of calories, which will easily lead to obesity if it is drunk for a long time. Most importantly, it will bring a great burden to the kidneys, which is also one of the hidden dangers of diabetes. Therefore, people who have diabetes themselves should try not to drink it. In addition, many teenagers, especially children, especially like this sweet taste. Professor Zhang Jiazhi said that this kind of sugar is very harmful to children's tooth development, and it is particularly easy to be corroded. According to a survey, the probability of tooth decay will increase by 59% for children aged 12, and by 220% for children aged 14. Some people may choose sugar-free carbonated drinks because of this, but Professor Zhang believes that although drinking carbonated drinks reduces sugar intake, these drinks are still very acidic and may also lead to tooth decay. Phosphoric acid causes osteoporosis. If you carefully observe the ingredients of carbonated drinks, especially cola, it is not difficult to find that most of them contain phosphoric acid. Usually people don't care, but this kind of phosphoric acid will affect your bones subtly, and drinking carbonated drinks often will threaten your bone health. Professor Wang Lixin said that the human body has requirements for various elements, so a large intake of phosphoric acid will affect the absorption of calcium, resulting in an imbalance between calcium and phosphorus. Once calcium is lacking, it will do great harm to the physical development of teenagers during their growth. Lack of calcium undoubtedly means slow bone development and osteoporosis, so some data show that the risk of fracture of teenagers who often drink a lot of carbonated drinks is three times that of other teenagers. According to the expert's advice, be careful when drinking and buying carbonated drinks, and don't drink a lot for a long time. Relatively speaking, carbonated drinks with pure fruit juice are rich in nutrition, and some drinks have a small amount of pulp precipitation, which can be supplemented with vitamins appropriately, but they are more suitable for young people and children, but they cannot be drunk every day or in large quantities at one time. And some carbonated drinks containing caffeine, cola is the most representative, although it has a refreshing effect, but it is generally suitable for adults to drink when they occasionally feel tired and depressed, not suitable for children. For low-calorie carbonated drinks, because of their low calories and low sugar content, they are more suitable for diabetics or people with special restrictions on sugar and calorie intake. In addition, when choosing carbonated drinks, especially in summer and autumn, you should buy products produced recently, and try to choose products from soft and hard cans when buying, because carbon dioxide will overflow during storage, affecting the taste, and it is easy to breed bacteria when drinking again. I would like to remind you that you must go to a regular sales place to buy products of well-known brands when buying carbonated drinks.
