Precise definitions vary by purpose and over time. Some high-protein foods, like meat prepared with saturated fat, may be considered junk food. Fast food and fast-food restaurants are often equated with junk food, although fast foods cannot be categorically described as junk food. Candy, soft drinks, and highly processed foods such as certain breakfast cereals, are generally included in the junk food category; much of it is ultra-processed food.
