I'm hearing a lot about junk food lately. No one has given a definition of what foods are junk.
Junk food is a slang word for foods with limited nutritional value.
Every person has their own list of foods that they call junk foods. I would include foods that are high in salt, sugar, fat or calories and low nutrient content. Salted snack foods, candy, gum, most sweet desserts, fried fast food and carbonated beverages are some of the major junk foods. Generally, they offer little in terms of protein, vitamins or minerals and lots of calories from sugar or fat. Rather than taking a radical approach and banning all but the simplest foods, judge each food based on the list of ingredients and Nutrition Facts label found on packages.
