Energy drinks are now available (可购得的) in nearly every store and they promise to make people feel more energetic and think more clearly. these products have names like Red Bull , Monster, 5-Hour Energy and so on, which appeal mainly to young adults and teenagers.

Chad is a medical researcher who got interested in studying energy drinks because of the explosion (猛增) in their popularing in the last few years.He says he and his research team have found three major things about energy drinks. One: there are huandreds of brands of energy drinks in most major countries. Two: the drinks are not clearly labeled (用标签标明) with enough information such as what are contained in the drink, the date and even t names of their makers. And three: the amount of caffeine ( 加啡因) varies greatly. Some contain as little as fifty milligrams, others as much as five hundred.

Some energy drinks contain a mixture of ingredients (配料) listed as an “energy blend”. But scientists do not know a lot about them and how they interact with each other. These ingredients may be dangerous for people who drink them. What is worse , he says, there is no listing of the amount of each ingredient. Some makers of energy drinks do provide warnings. For example, a popular energy drink warns against use by people who are nursing a baby or under the age of twelve.

Chad and his team suggest labeling energy drinks with the amount of caffeine and other ingredients clearly in order to protect the health of the public. And the government officials are considering their suggestions now.
