Snacks are small portions of food consumed between main meals, serving as a way to curb hunger, boost energy, and provide essential nutrients throughout the day. They can vary widely in type and composition, ranging from healthy options like fruits, nuts, and yogurt to more indulgent choices like chips, cookies, or candy. Snacks are often chosen for convenience and portability, making them popular for on-the-go lifestyles. Incorporating nutritious snacks can help maintain energy levels, support metabolic health, and prevent overeating during main meals. The key to effective snacking is to choose nutrient-dense options that contribute to overall dietary goals while satisfying cravings.
