Bananas
Bananas are nature’s prepacked and portable healthy snack. They’re filled with fiber, vitamin B6, and potassium — nutrients that promote sustained energy and muscle function, Berman says. Bananas are particularly appealing as a pre- or post-workout snack. Pair a banana with a glass of low-fat milk or a cup of yogurt for an energizing combination of fiber and protein — a combo that also makes a great breakfast to start your day.
