The main components of carbonated drinks include carbonated water, citric acid and other acidic substances, as well as sugar, spices, and some also contain caffeine and artificial colors. Except that sugar can replenish energy for human body, aerated "carbonated drinks" contain almost no nutrients. Generally does not contain vitamins and minerals.

(1), the benefits of carbonic acid

For example, salt soda, which is popular now, used to be a drink we often drank when we were children to supplement the salt and water lost by sweating in summer. From a scientific point of view, it is better than boiled water for people who work at high temperature and sweat too much. How easily calcium is lost when sweating. When the loss of calcium in sweat is greater than 100 mg per hour, hand-foot muscle spasm is easy to occur. At this time, drinking boiled water has no effect, while drinking salt and soda can quickly replenish a lot of salt and calcium lost by sweating and relieve cramps. Moreover, when we exercise or it is very hot in summer, drinking carbonated drinks will release the heat in the body by burping, which will make people feel cool and comfortable!

(2), the shortcomings of carbonic acid (gray)

① It is easy to cause obesity: Generally, the sugar content of carbonated drinks is about 10%, and a small bottle of calories will reach one or two hundred kilocalories, which is easy to make people fat if they drink it frequently.

② Damage to teeth: Acidic substances and acidic sugar by-products in soft drinks will soften enamel and promote the formation of cavities. If the enamel softens, coupled with bad habits such as incorrect brushing and grinding, it will lead to tooth damage.

3 Affect digestion: Drinking too much carbonated drinks is not good for the stomach, and it also affects 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.

④ Causes osteoporosis: Carbonated drinks, especially cola, mostly 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.

⑤ It is easy to cause kidney calculi: After drinking too much carbonated drinks containing caffeine, the calcium content in urine will greatly increase, making it easier to get stones. If you consume more caffeine, the risk is even greater. Magnesium and citrate in human body can help prevent the formation of kidney calculi, but after drinking caffeinated drinks, they are excreted, which greatly increases the risk of lithiasis.

In a word, carbonated drinks have both advantages and disadvantages. We can drink, but not often!

2. The main components of human bones and teeth:

They are all compounds with cations mainly Ca2+.

The main component of enamel and dentin is hydroxyapatite. Osteogenesis is mainly calcium carbonate. Of course, there are other substances, such as organic matter.

Attachment: Egg shells can replace teeth, so can fish bones, and the ingredients are the same.
