Coffee and cola can do harm to children's health.

Coffee contains caffeine, which is an obvious excitatory nerve stimulant, which makes people feel sleepy and can improve work efficiency, but it can also cause euphoria and addiction.

Through a large number of scientific studies, it has been found that drinking coffee regularly can cause the following harm to children due to the effect of caffeine:

(1) Children who drink coffee often can cause restlessness, loss of appetite, insomnia, memory loss, inability to concentrate on study, and even some people think that children who drink coffee frequently are prone to ADHD. Caffeine can also damage vitamin B1 in children, causing vitamin B1 deficiency.

(2) caffeine may cause intestinal spasm, and children who often drink coffee are prone to abdominal pain, affecting food intake and causing malnutrition.

(3) American scientists found that coffee drinkers' urine calcium was twice as high as that of non-drinkers, that is, the excretion of calcium increased. Therefore, drinking coffee for a long time can affect the bone development of children.

Coca-Cola is another popular drink in the world, which is sold in more than 150 countries. In addition to sugar, carbonated water, phosphoric acid and caffeine, the drink has some ingredients that have been unknown for decades. Coca-Cola and other brands of Coke are caffeinated drinks. Children often drink Coke, which may have the same adverse consequences as regular coffee consumption.
