Junk food—it’s a term people use loosely, and it can mean different things depending on the person. Pizza may be junk food to some and a staple to others. So for the sake of clarity, let’s define junk food as items that are high in calories but provide little to no nutritional value.
Based on this definition, pizza provides the high calories and may or may not score in the nutritional category, depending on the ingredients and preparation. Foods and beverages that easily fit the junk food definition include foods high in sugar, such as cookies, cakes, pies, candy, and sugary soda; and high-fat snacks, such as potato chips, French fries, cheese crackers, and just about anything deep-fried.
