Foreign media say Starbucks caffeine expert: children should not drink
Recently, a study found that a large cup of Starbucks coffee contains more than 3/4 of the daily safe intake, according to the Daily Mail.
A large 16-ounce cup of coffee contains twice as much caffeine as the recommended limit for pregnant women, while the 8 ounces of coffee brewed by yourself is usually more than the average daily allowance for 10-year-olds.
However, scientists stressed that these statistical averages do not reflect the actual per capita differences, gender, genes and other factors may have a great impact on the level of caffeine tolerance.
An individual's tolerance level may also be affected by other drugs. When women take contraceptive, caffeine metabolism slows down; smokers deal with the stimulant faster.
A study organized by government regulator Health Canada found that daily consumption of caffeine up to 400mg per person had no negative effects such as anxiety and heart reaction.
According to the Food Standards Agency's guidelines, the daily allowable intake for pregnant women is 200mg and 75mg for 10-year-olds. According to the food composition table edited by Chemical and Chemical News, a 16-ounce cup of Starbucks coffee contains 330mg caffeine. But Starbucks denied this, saying that their large cups of coffee contained only 140mg caffeine.
BruceA.Goldberger, director of forensic toxicology at the University of Florida, commented in Chemical and Chemical News: people usually do not understand the potential risks of these drinks. Caffeine is a stimulant and can have negative effects when ingested at high enough levels.
It is widely believed that the lethal dose of caffeine is about 10g, which is equivalent to drinking 75 cups of 8-ounce coffee or 120 cans of Red Bull in just a few hours.
