The term has become common usage amongst many different groups over the years, including opponents of fast food industries and environmentalists. Junk food typically contains high levels of fat, salt or sugar and numerous food additives such as monosodium glutamate and tartrazine; at the same time, it is lacking in proteins, vitamins and fiber, among others. It is popular with suppliers because it is relatively cheap to manufacture, has a long shelf life and may not require refrigeration. It is popular with consumers because it is easy to purchase, requires little or no preparation, is convenient to consume and has lots of flavor. Consumption of junk food is associated with obesity, heart disease, Type 2 diabetes and dental cavities. There is also concern about the targeting of marketing at children.

Once children start consuming junk foods, their intake of high-protein-vitamins-roughage diet substantially decreases and intake of milk and healthy fruit juices is replaced by soft drinks. This can cause a deficiency of calcium, milk being a rich source of calcium, resulting in weakening of bones.

Some types of chips that are said to be "junk food" may actually be partially beneficial because they may contain polyunsaturated and monounsaturated fats. However, since they are fats, the intake of these should be kept to a minimum. It should also be understood that the detrimental effects of the empty calories may outweigh the benefits of the unsaturated fats. These foods tend to be high in sodium, Ówhich may contribute in causing hypertension (high blood pressure) in some people.
