Prune Juice
With sugar and cream stirred in, coffee is one enticing morning treat. But next time you reach for your thermos, fill it with prune juice! The thick, crisp juice helps regulate the proper level of electrolytes in your body, which in turn leads to increased stamina, according to Staci Nix, author of Williams’ Basic Nutrition and Diet Therapy. If the flavor of prune juice is overpowering, try diluting it with water or apple juice for a thinner blend.
