Hello friends. In addition to being delicious, drinking Coca-Cola not only has no benefits to the human body, but also has many harmful effects! The main ingredients of cola are syrup and carbon dioxide gas, which are not nutritious for the body. In addition to causing obesity, regular drinking of cola may also lead to dental caries, osteoporosis, heart disease, etc. It is also a potential risk factor for modern diseases such as diabetes. Not to mention the pigments, spices, caramels and other additives contained in cola that are harmful to the human body. Caffeine alone is a substance that is harmful to health. Coke, grapefruit, etc. are all favorite drinks of Hong Kong people. However, a survey by the School of Dentistry of the University of Hong Kong shows that drinking three cans a day over many years may cause tooth decay and tooth acidity. If you drink 1 liter of acidic and sugary drinks a day for 1 to 2 years, the enamel on the tooth surface will be eroded away by acid. Philip Dental Hospital receives nearly 20 complex cases of teeth being eroded by acidic beverages every year. Some patients drink several cans or bottles of cola every day, causing almost all the enamel that protects their teeth to be eroded away by acid. The pH value ranges from 1 to 14 degrees, with 7 degrees being neutral. If the acidity of the drink is lower than 5.5 pH, the enamel can be dissolved. Caffeine is a drug that has an exciting effect on the central nervous system, heart, and blood vessels, and it impairs memory. In addition, for children, caffeine is irritating and can stimulate gastric peristalsis and gastric acid secretion, causing intestinal spasm. Children who often drink coffee are prone to unexplained abdominal pain. Long-term excessive caffeine intake can lead to chronic gastritis. Caffeine can dilate the capillaries on the gastrointestinal wall, stimulate kidney function, increase renal water flow, cause polyuria in children, increase calcium excretion, and affect children's bone development. At the same time, caffeine can also destroy vitamin B1 in children and cause vitamin B1 deficiency. A 355 ml can of cola contains 65 mg of caffeine, a 350 ml can of oolong tea contains 80-120 mg of caffeine, and a cup of instant coffee contains 85-200 mg of caffeine. Normal people should not consume more than 200 mg of caffeine per day, otherwise chronic poisoning may occur. Children should stay away from coffee and drink as little caffeinated beverages as possible. And some chemicals in cola, such as sodium, can increase blood pressure. Experts remind that high blood pressure will increase people's risk of heart disease, stroke and kidney disease and must not be ignored. 1. Coke contains caffeine, which makes it addictive if you drink it for a long time. 2. Coke contains carbonic acid, drinking too much is bad for your health. Because the human body is in the best condition when it is weakly alkaline. 3. There is no protein, etc. and lack of nutrients. 4. Drinking it for a long time will make you fat because it contains sugar. 5. In addition, when carbonated drinks represented by Coca-Cola first came out, because of their good taste, the gas they produced could bring out the heat in the stomach, giving people a feeling of comfort and excitement. After getting used to drinking, people will develop a certain dependence on carbonated drinks. In fact, carbonated drinks have no nutritional value. According to reports, various types of carbonated drinks contain high sugar content, and drinking them for a long time can easily lead to obesity. Coke contains sodium chloride, which is similar to caffeine and also contains preservatives. These ingredients are not good for the body and have no nutritional value. Drinking these drinks for a long time will definitely cause problems. Drinking Coke is harmful to children. Coke contains caffeine, and a 340-gram bottle of cola-type drink contains 50 to 80 mg of caffeine. Some people have done experiments and found that adults taking more than 1 gram of caffeine at a time can cause excitement in the central nervous system, accelerated breathing, tachycardia, insomnia, vertigo, and tinnitus. Even if less than 1 gram is taken at a time, poisoning symptoms such as nausea, vomiting, dizziness, palpitations, and precordial pain may occur due to stimulation of the gastric mucosa. Children are more sensitive to caffeine than adults, so do not give them cola-type drinks. Girls should drink Coke to prevent osteoporosis. Studies have shown that soda will accelerate bone loss, especially girls who like to drink cola. The chance of fracture is five times higher than that of those who do not drink soda! Experts pointed out that the phosphoric acid in cola may be the cause of easy fractures. Phosphoric acid is harmful to bone quality because phosphoric acid has an adverse effect on calcium metabolism and bone quality. On the other hand, young girls who drink cola may have insufficient milk intake, which makes their bodies lack calcium and are prone to fractures. Newlyweds should also be careful about drinking cola.

Because most cola-type drinks contain a high content of caffeine, caffeine can easily enter the fetus through the absorption of the placenta, which can endanger the fetus's brain, heart and other organs. It can also cause malformations or congenital diseases in the fetus. Therefore, experts suggest that in addition to abstaining from smoking and alcohol, newlyweds and couples who want to have children should not drink cola-type drinks. Even after the baby is born, nursing mothers should not drink cola-type drinks. Because caffeine can also enter the baby's body indirectly with milk and harm the baby's health. Elderly people should not drink cola. Coke has a diuretic effect and can reduce calcium absorption by half. Frequent consumption of caffeinated beverages by the elderly can aggravate the lack of calcium in the body, cause osteoporosis, and easily lead to fractures. In addition, drinking too many caffeinated drinks can increase blood lipids and easily aggravate arteriosclerosis. Patients with hyperlipidemia and hypertension drink more, which will accelerate the deterioration of the condition. For smokers, caffeine, under the action of nicotine's mutagenic substances, can easily cause mutations in certain tissues of the body and even lead to the production of cancer cells. In order to avoid the above hazards, you should change your habit of smoking and drinking cola
