Sweet potato as juice? You bet. This pumpkin-colored tuber is not only a surprising—and easily sourced—ingredient with an appealing flavor, it also helps you get your glow on. The carotenoids in orange-colored vegetables like carrot and sweet potato have such beneficial effect on skin, they have a scientifically validated "attraction factor"—meaning that warm glow you naturally acquire makes others rate you as more attractive.

Orange and carrot add depth and color to red apple juice plus another gift: a good dose of vitamin C and beta-carotene.
