The rigorous caffeine systematic Review of ILSI North America, published in the Journal of Food and Chemical Toxicology (Food and Chemical Toxicolog) in April 2017, reaffirmed the benchmark conclusion established by Nawrot et al in 2003 that there was no adverse effect or no change in acceptable caffeine intake, 400mg / day for adults (lethal dose of 10g) It is 300mg / day for pregnant women (including those preparing for pregnancy) and 2.5mg / kg / day for 12-year-old 19-year-old and 3-year-old 12-year-old children. These data are simplified to 400mg / kg / day for adults)-300mg / day for pregnant women (pregnant women)-2.5mg / day for teenagers and children (BW is the abbreviation for Body Weight) because they are not yet fully developed and their weight varies greatly. This 400-300-2.5 BW is the security password for caffeine. However, when interpreting this data, people should note that this series of figures is only used as a reference value for ordinary people. Because there are too many variables among individuals, no data can be fully applied to the safe dose of the whole population. Practical application should be considered according to their own conditions, and this data should not be regarded as the upper limit of caffeine intake or iron law.

The report's conclusions on the recommended daily intake of 400mg caffeine for healthy adults are consistent with the US dietary guidelines for 2015-2020 to drink 3-5 cups of coffee per day (240ml per cup), the caffeine intake limit of 400mg per day, and the EU Food Safety Agency (EFSA) recommendation of 400mg per day in 2015. Taiwan's current recommendation for caffeine intake is that it is best not to exceed 300 mg a day.
