单选题 Eating is important to everyone. But not many people have time to think about what to eat.
"Fast food is easy," says Sarah Hudson, a 14-year-old high school student from America. She is enjoying her lunch at McDonald's. "It's quick and it is delicious. If they made healthy food, I wouldn't buy it." She eats fast food about twice a Week.
Now each American eats about three hamburgers and four bags of French fries (or: potato chips) every week. That is 2,520 calories (卡路里). A person needs about 2,000 calories for a whole day.
Most Americans know that fast food isn't good for them. But it seems that they can't give it up. In fact, more and more people are eating fast food, and fast food restaurants are part of American life. 96% of American school children know McDonald's.
Because they love the French fry, it's no surprise that children are getting bigger. In America, 33% of them are overweight (or: too heavy). That makes it hard for them to move around, go upstairs and even breathe. They will probably have health problems later in life. Of course it's not just young people who are getting heavier. It's all Americans.
