1. Coke contains caffeine, which will be addictive if you drink it for a long time. Coke contains carbonic acid, and drinking too much is bad for your health. Because the human body is at its best when it is weakly alkaline. 3. Coke contains a lot of sugar, which is absorbed quickly, and it is easy to cause excessive calorie intake, which will make you fat if you drink it for a long time. Drinking too much coke will hurt your teeth. Because phosphoric acid and carbon dioxide in cola dissolve to form carbonic acid, it has a certain corrosive effect on enamel. Phosphoric acid in cola is a strong acid, which will bring a certain burden to the stomach. Patients with gastric ulcer had better not drink it. 6. Coke can lead to osteoporosis. People who like coke are five times more likely to have a fracture than those who don't drink soft drinks. Phosphoric acid in cola may be the reason for the increase of fracture rate, because a large amount of phosphorus will affect the body's absorption of calcium. Caffeine contained in cola also has the effect of decalcification. 7. Drinking too much cola is easy to get esophageal cancer. Researchers speculate that it may be the pressure of carbon dioxide that causes gastric acid to flow back to the esophagus, thus stimulating the esophagus and inducing esophageal cancer. Patients with digestive tract diseases and people with poor gastrointestinal function should strictly control the consumption of carbonated drinks. 8. Coke contains a high content of caffeine, which will harm the brain, heart and other organs of the fetus when it enters pregnant women.
