It also found that children could consume up to 2.5 mg of caffeine a day without negative health effects.

The study, published in the Food and Chemical Toxicology journal, looked at nearly 740 caffeine-related studies that took place between 2001 and 2015. It found that the average coffee consumption across all age groups was about one cup a day.
“This Systematic Review provides evidence that furthers our understanding of caffeine on human health,” said Dr. Eric Hentges, the executive director of ILSI North America. “Also, this review provides the research community with data and valuable evidence to support the development and execution of future research on caffeine safety that will impact public health."
