If a teenager drinks a moderate amount of coffee during the growth and development period, it will not cause too many ingredients to enter the body or increase the metabolic burden of the body. It will not have a particularly noticeable adverse effect on the growth and development, as well as the physical and mental health of the teenager.

A moderate amount of coffee for teenagers also helps to increase the excitability of the sympathetic nerves, relieving teenagers of fatigue and bad moods during the learning process. If teens drink too much coffee, the caffeine and other substances contained in coffee will stimulate the nerves, which is not conducive to the stability of the teenager's mood, and may even lead to an increase in insomnia in teens.

It is recommended that teens do not add too much sugar or lipids when drinking coffee to avoid increasing the risk of obesity.
