Kids love fast food. And the fast food industry definitely loves kids. It couldn't survive without them. Did you know that the biggest toy company in the world is McDonald's? It's true. In fact, one out of every three toys given to a child in the United States each year is from a fast food restaurant. Not only has fast food reached into the toy industry, it's moving into our schools. One out of every five public schools in the United States now serves brand name fast food. But do kids know what they're eating? Where do fast food hamburgers come from? And what makes those fries taste so good?
