Caffeine in coffee is a central nervous system stimulant, and children's brain function and liver and kidney metabolism function are not fully developed. Drinking coffee is easy to increase the burden on the heart, brain, liver and kidney, and it is easy to have adverse consequences. The substances in coffee inhibit the absorption of calcium, thus affecting the child's bone development. Therefore, it is not recommended for children to drink coffee, and they can eat more fresh fruits or vegetables.
