What's Junk Food?
Junk food isn't actually made of garbage. People use the term junk food to describe a food that has few of the nutrients your body needs, and a lot of fat, sugar, and salt, which your body can easily get too much of.
Potato chips, candy, and soft drinks are often considered junk food. If you like these snack foods, the trick is to eat them in small portions so that you still get the nutrients you need each day.
