Fast snacks are quick and convenient food options that can be eaten on the go. They are often pre-packaged or easy to prepare, making them ideal for busy lifestyles. Common examples include granola bars, trail mix, and fruit cups. These snacks are designed to provide a quick energy boost without requiring extensive preparation. Many fast snacks are also marketed as healthier alternatives to traditional junk food. They may contain whole grains, nuts, or dried fruits, offering nutritional benefits. However, it's important to check labels for added sugars and preservatives, as some fast snacks can still be high in calories and low in essential nutrients.
