Snack foods refer to small, easily consumed food items that are typically eaten between meals as a quick source of energy or sustenance. These types of foods can range from sweet treats like cookies and candy, to savory options such as chips and crackers, and even healthier choices like nuts and dried fruits. Snack foods are designed to be convenient and portable so that people can enjoy them on the go or while engaged in other activities. They are popular because they provide a quick way to satisfy hunger and cravings without requiring a full meal.
