How often do you eat the rainbow? How many cups of vegetables do you eat a day? I am talking about raw vegetables loaded with live enzymes, nutrients, and vitamins. Think. Is it 2 cups or 5 cups or 20 cups? It is hard to eat 20 cups of raw vegetables, but you can juice the rainbow and consume tons of vegetables, giving your body exactly what it needs, with the Juice Yourself Alive in 24 Hours plan.
