David, a 12-year-old English boy, loves hamburgers very much. He has one hamburger in the morning, and three hamburgers and two ice creams in the afternoon. For dinner, what does he have? Three hamburgers and some cola!
Some scientists say, "Hamburgers, ice cream and cola are nice but eating them too much is not good." If we have food like hamburgers too much, what can we get?
Scientists have an experiment(实验) on rats(老鼠) to find the answer.
Here are three groups of rats. Group One eat fruit and vegetables. Group Two eat some vegetables and hamburgers. But they can eat hamburgers for only one hour every day. Group Three have hamburgers and vegetables, too. But rats in this group can eat hamburgers all day. The rats in Group Three like hamburgers very much and always want them. After the experiment, they are the fattest.
Can it be the same with people? Some scientists say "Yes". It is OK to love food like hamburgers, but having so many hamburgers a day like David makes you fat. You don't want to be too fat, right? An ice cream is nice and cool. It's OK to have one ice cream after dinner. But it's not OK to have five ice creams after dinner. We don't want to be the fattest "rats".
