Twin sisters Mary Corpening Barber and Sara Corpening Whiteford love to blend smoothies for their families. "Smoothies can be sweet-tooth satisfiers, energy enhancers, cleansing on-the-go meal replacements, pick-me-up snacks, terrific kid-pleasing shakes, and even toddies for adults," they say. Here, they share three concoctions from their new book Super-Charged Smoothies (Chronicle). They're designed to make you smarter, leaner, and healthier—and taste delicious, as well!
