美国得克萨斯大学研究人员报告说,不少能量饮料不标注咖啡因含量,可能导致饮用者过度摄取;而咖啡因可能与能量饮料中的其他成分,如牛磺酸、维生素或矿物质发生反应。有时,人们把能量饮料与酒混在一起喝,这对心率、血压甚至人的精神状态可能都有影响。 Researchers at the University of Texas in the United States report that many energy drinks that do not label caffeine levels may lead to overdoses by drinkers, and that caffeine may react with other ingredients in energy drinks, such as taurine, vitamins or minerals. Sometimes people drink energy drinks mixed with alcohol, which may have an impact on heart rate, blood pressure and even mental state.
