Healthy snacks can help maintain energy levels and provide essential nutrients. One great option is Greek yogurt, which is high in protein and can be paired with fruits or nuts. Another tasty choice is hummus served with carrot sticks or cucumber slices, offering fiber and healthy fats. Almonds are a convenient snack packed with vitamins and minerals, while apple slices with peanut butter provide a satisfying mix of sweetness and protein. Lastly, popcorn (air-popped) is a whole grain snack that can be enjoyed without added butter or salt, making it a light and crunchy option.
