Definition: Any type of food that is prepared and sold in a quick manner.
Fast food restaurants generally serve hamburgers, sandwiches, French fries or similar side dishes, and soft drinks. They may also serve ice cream, small desserts, and coffee drinks.
Fast foods are frequently inexpensive and may be considered junk food because they are usually low in nutritional value, but high in calories from fat and sugar. Fast foods are usually high in sodium as well.
