Eating is important to everyone. But not many people have time to think about what to eat."Fast food is easy," says Sarah Hudson, fourteen-year-old high school student from America. She is enjoying her lunch at McDonald's. "It is quick and delicious."She eats fast food twice a week. Most Americans know that fast food isn't good them.But it seems that they just can't give it up. In fact, more and more people are eating fast food, and 96% of American school children know McDonald's and KFC. It's no surprise that children getting heavier because they love eating French fries. In America, 33% of them are too heavy. That makes it hard for them to move around, go upstairs and even breathe. If they go on eating like this, maybe they will have health problems later in life.
