"Junk food" is a term used to describe food that is high in calories from sugar and/or fat, and possibly sodium, making it hyperpalatable, but with little dietary fiber, protein, vitamins, minerals, or other important forms of nutritional value. It is also known as HFSS food (high in fat, salt and sugar). The term junk food is a pejorative dating back to the 1950s. Many different kinds of junk food can be easily found in most supermarkets and fast food restaurants. Because of such easy access to it, people are most likely to consume it. 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. Most junk food is ultra-processed food.
Concerns about the negative health effects resulting from a junk food-heavy diet, especially obesity, have resulted in public health awareness campaigns, and restrictions on advertising and sale in several countries. Current studies indicate that a diet high in junk food can increase the risk of depression, digestive issues, heart disease and stroke, type 2 diabetes, cancer, and early death.
