A smoothie is a thick and creamy beverage made from pureed raw fruit, vegetables, and sometimes dairy products like milk, yogurt, ice-cream or cottage cheese, typically using a blender. A smoothie containing dairy products is similar to a milkshake, though the latter typically contains less fruit and often uses ice cream or frozen yogurt. Blending up a kiwi or two in a green smoothie helps brighten up the flavor without adding a bunch of extra calories, especially when there’s a lot of greens.
