Snack food refers to small portions of food that are typically consumed between meals. These foods are often convenient, portable, and ready-to-eat, making them popular choices for people on the go. Common examples include potato chips, granola bars, and popcorn. Snack foods can be sweet or savory and are available in various forms, including packaged items and homemade treats. Many snack foods are designed to be quick and easy to prepare, requiring little to no cooking. They can be found in grocery stores, convenience stores, and vending machines. While some snack foods are nutritious, others may be high in sugar, salt, or unhealthy fats, so it's important to choose wisely for a balanced diet.
