Young children may face serious health risks from popular energy drinks, such as Monster, Red Bull and Rock Star, 【1】 causing heart problems and other life-threatening conditions, according to the findings of new researches.
During a presentation at the annual Cardiac Scientific Sessions 2014 meeting of the American Heart Association (AHA), researchers warned about the risk of allowing young children 【2】 to the energy drinks, which contain high amounts of caffeine(咖啡因) and other stimulants.
Researches 【3】 that the energy drinks are not intended for young children and are not safe for them to consume. Steven Lipshultz, M.D., lead author of the study, is calling for a warning on all energy drink cans and bottles, warning parents of the risk of allowing children to drink them.
Researchers say it is difficult to know exactly how much caffeine is contained in each can or bottle of energy drinks, since they are often 【4】 as dietary supplements (补充物), which allow the manufacturers to avoid FDA regulations.
Energy drink manufacturers have compared the amount of caffeine in their products to that in hot drinks sold in coffee houses, but their products are often packaged in very large sizes and they are not sold in 【5】 environments like coffee houses, which typically would not serve young children. Energy drinks are widely available in 【6】 stores next to traditional soft drinks, typically packaged in very similar cans and using similar marketing techniques.
Some energy drinks in many of the popular lines can contain up to 400 mg of caffeine per can. In comparison, a cup of coffee typically has around 100 mg of caffeine. Caffeine poisoning can occur in adults at levels higher than 400 mg a day; however, children under 12 can 【7】 caffeine poisoning at only 2.5 mg per 2.2 pounds of body weight.
A study published in September 【8】 up the new findings, revealing energy drinks may cause serious heart problems. French researchers revealed the popular energy drinks may be linked to 【9】 risk of irregular heartbeats and even sudden death.
