The effect of caffeine on health has been widely studied.

• Large amounts of caffeine may decrease bone mass density, most likely by interfering with the body's ability to absorb calcium. This may lead to osteoporosis.

Caffeine may have a negative effect on a child's nutrition if caffeinated drinks replace healthy drinks, such as milk. A child who consumes caffeine may also eat less, because caffeine reduces the appetite.
