Juices are the perfect fast food for today's eat-on-the-run lifestyle. They contain all the goodness of the whole product in a condensed form. For example, a pound of carrots can be a significant source of calcium and protein, but those ten carrots may be more than your willing to eat at a single meal. Juicing concentrates that one pound into a single glass of easy to drink juice. These nutrients are quickly assimilated since the body does not have to separate out of the fiber.
