Advocates of juice detoxing claim it's an age-old cure that continues to work in modern times to alleviate the body of excesses. Juice detox diets revolve around juices as well as solid foods like whole fruits and vegetables, while juice fasts are liquid diets that exclude all solid foods. Proponents of juice detox diets claim they promote self-healing and rejuvenation by giving the body a rest from its job of digesting food and supplying the body with the vitamins, nutrients, and antioxidants it needs to draw out and eliminate toxins via increased urination and bowel movements.
