The AAP states that there is no ideal age for a child to begin consuming coffee—or energy drinks, soda, or other caffeinated beverages—because they "have no place in the diet of children or adolescents." According to Abrams, they should keep to water, milk, and, to a lesser extent, juice. She also notes that caffeine can irritate the stomach acid of young people, so moderation is recommended. In conclusion, the AAP says it's not necessary to avoid drinking coffee if you're over 18 because it isn't harmful. However, youth should be taught about the dangers of caffeine since its effects can be toxic if consumed in large amounts over time.
