Experts pointed out that phosphoric acid in cola may be the cause of easy fracture. Phosphoric acid is harmful to bones because it has adverse effects on calcium metabolism and bones. On the other hand, young girls who drink cola may have insufficient milk intake, which leads to calcium deficiency, so they are prone to fracture.

Newlyweds should also be careful when drinking coke. Because most cola drinks contain high content of caffeine, caffeine can easily enter the fetus through the absorption of placenta in the body, which will harm the brain, heart and other organs of the fetus, and also cause fetal malformation or congenital diseases. Therefore, experts suggest that newlyweds and couples who want to have children should not drink cola drinks except smoking. Even after the baby is born, lactating mothers can't drink cola drinks. Because caffeine will also enter the baby indirectly with milk, which is harmful to the baby's health.

Old people shouldn't drink coke. Cola has diuretic effect, which can reduce the absorption of calcium by half. Old people often drink caffeinated drinks, which will aggravate the lack of calcium in the body and easily lead to osteoporosis and fractures.

In addition, drinking too many caffeinated drinks will increase blood lipids and easily aggravate arteriosclerosis. Patients with hyperlipidemia and hypertension drink more alcohol, which will accelerate the deterioration of their condition. For smokers, under the action of nicotine mutagen, caffeine can easily mutate some tissues of the body and even lead to the production of cancer cells. In order to avoid the above hazards, we should change the habit of smoking and drinking coke.
