Carbonated beverages contain more additives, such as acids, preservatives, etc. Some of them also contain caffeine, artificial colors and other ingredients, and sugary carbonated beverages also contain a lot of sugar. Therefore, carbonated beverages can cause a series of effects on the human body, such as affecting bone quality, leading to obesity, affecting oral health, gastrointestinal disorders, increasing the burden on the kidneys, etc. 1, affecting bone quality: carbonated beverages contain more high phosphate, long-term excessive drinking will affect the absorption of calcium because of excessive phosphorus intake, causing calcium deficiency. Especially in childhood, which is an important period for bone development, calcium deficiency not only affects bone development but also growth and development, and adults are prone to osteoporosis; 2, leading to obesity: the sugar content of sugary carbonated beverages is about 10%, and long-term consumption of carbonated beverages, especially for people who exercise less, can easily cause obesity because of excessive sugar intake, and also increase the risk of developing diabetes and hyperlipidemia. It also increases the risk of diabetes and hyperlipidemia. And diabetic patients drinking sugary drinks may also be aggravated by increased blood sugar; 3, affect oral health: carbonated beverages in phosphoric acid, carbonic acid components and tooth enamel reaction, resulting in the dissolution of tooth mineral crystals. In the long run, it will lead to the loss of tooth enamel, make the tooth surface become fragile and thin, and also make the dentin lose the protective layer and occur caries; in addition, carbonated drinks are easy to make the oral pathogenic bacteria multiply, and also cause periodontitis, calculus and other oral problems; 4, gastrointestinal disorders: carbonated drinks contain a lot of carbon dioxide gas, after drinking it, it will lead to early satiety, gastric distension, and affect people’s appetite; also It may inhibit the beneficial bacteria in the human body, and people with bad stomach and intestines will drink too much to produce acid reflux and indigestion; 5, increase the burden on the kidneys: the kidneys play a function to help the body’s water metabolism, if the intake of carbonated drinks is too much, the metabolism of sugar in carbonated drinks results in sugar, which in turn produces a large number of purine substrates, stimulating uric acid secretion and increasing the burden on the kidneys. At the same time, the calcium content in the urine increases, which may lead to kidney stones. It is recommended to drink carbonated beverages in moderation, pay attention to a healthy diet, balance food and maintain good eating habits.
