Deeply buried pollutants and chemicals from our tissues are released into elimination channels too rapidly during a water fast. Sometimes, the physical and emotional stress of a water fast even overrides the healing benefits. Vegetable and fruit juices are alkalizing, so they neutralize uric acid and other inorganic acids, better than water, and increase the healing effects. Juices support better metabolic activity for fasting, too. Metabolic activity slows down during a water fast as the body attempts to conserve dwindling energy resources that further reduce productive cleansing.
Juices are very easy on digestion - easily assimilated into the bloodstream.
They don't disturb the detoxification process. The first step of your cleanse is elimination. You'll be cleaning out mucous and toxins from the intestinal tract and major organs. Everything functions more effectively when toxins, obstructions and wastes are removed. Try to drink 8 glasses of water each day of your fast in addition to your juices.
