Snack foods are convenient, ready-to-eat items that are often enjoyed between meals. They come in various forms, including sweet and savory options, and are designed to satisfy cravings or provide a quick energy boost. Popular examples include potato chips, cookies, and nuts. These foods are typically packaged for portability, making them ideal for on-the-go consumption. While they can be delicious and satisfying, it's important to enjoy them in moderation, as many snack foods can be high in calories, sugar, or salt, which may impact overall health if consumed excessively.
