Why do some people say that men can't drink carbonated drinks?

Carbonated drinks-affect your calcium and iron.

Carbonated drinks include all kinds of soda, flavored soda, cola, flavored cola, and all kinds of carbonated drinks.

There are four reasons why carbonated drinks should not be drunk often:

Carbonated drinks contain gas, namely carbon dioxide.

Carbon dioxide can stimulate the secretion of gastric juice, and hyperacidity can easily lead to bloating, loss of appetite and reduction of daily food intake. Insufficient intake of nutrients in diet will affect normal growth and development, learning effect, sports performance, work performance and health.

Carbonated drinks contain sugar.

A can of 355 c.c cola contains about 35 grams of sugar, equivalent to 140 calories, equivalent to half a bowl of rice. However, only the calories are equal, but the nutrients are quite different, because sugar has only calories and no other nutrients at all. It is empty card food or junk food with calories. If you drink regularly, every little makes a mickle, you will gain weight and easily develop a bad eating habit of being sweet. You only like sweet water, not boiled water. In addition, sugar has a bad effect on dental health.

Phosphoric acid, another component of carbonated drinks

Phosphoric acid can reduce the absorption of calcium in the body and affect the normal development of bone growth and height. Children and adolescents in growth and development need enough calcium to make bones grow and develop normally, maintain good bone metabolism and achieve the best bone density, so it is even more inappropriate to drink carbonated drinks. In addition, phosphoric acid will hinder the absorption of iron, which is one of the main substances for making blood. Once iron is not enough, it will cause iron deficiency anemia. Children who are growing fast need enough iron to make blood quickly. Especially adolescent girls, the demand for iron is higher, because a lot of iron is lost every month during menstruation. Therefore, girls who love carbonated drinks are more prone to iron deficiency anemia.

Caffeine contained in various colas.

Caffeine can stimulate myocardial contraction and accelerate heartbeat and breathing; It will stimulate gastric acid secretion and harm the stomach; It has diuretic effect, and the elderly are prone to dehydration; Long-term drinking will be addictive. Once you don't drink it, you will feel uncomfortable, listless or have a headache. If you drink too much for a long time, that is, caffeine exceeds 200 mg every day, there will be chronic poisoning phenomena such as indigestion, headache, insomnia, nervousness, trembling, irritability and rapid heartbeat. Caffeine is found in cola, tea and coffee. A can of 355 c.c cola contains 65 mg of caffeine, a can of 350 c.c oolong tea contains 80 ~ 120 mg, and a cup of instant coffee contains 85 ~ 200 mg. Therefore, if you drink more than three cans of coke a day, or drink a can of coke, plus a can of oolong tea and a cup of coffee, you will consume more than 200 mg of caffeine, which will easily lead to chronic poisoning if you drink it for a long time.

Tooth corrosion (the protective layer becomes thinner and the teeth become brittle) is caused by acidic substances, while dental caries is caused by eating polysaccharides. Dr. Locke observed that the teeth of 12-year-old teenagers who drank 28 grams of sparkling drinks every day were obviously eroded; Drinking 4 glasses of sparkling drinks every day, the tooth damage of adolescents aged 12 is as high as 25.2%, and that of adolescents aged 14 is as high as 5 1.3%.
