Healthy alternatives to common snack foods include options like fruits, vegetables, and nuts instead of processed snacks. For example, fresh fruit, such as apples or berries, can satisfy sweet cravings while providing essential vitamins. Veggies like carrot sticks or bell pepper slices offer crunchiness alongside fiber and nutrients. Nuts and seeds provide healthy fats and protein, helping to keep you full longer. Additionally, whole grain options like air-popped popcorn or rice cakes can be flavorful and lower in calories than chips, encouraging healthier snacking habits.
