Besides being dehydrating, the SAD (standard American diet) leaves behind mucus in our system. At first, when we are very young, the bowels are able to keep up and expel this sticky residue through our stools, but eventually it gets backed up. Trust me when I say that one good movement a day is no where near enough to keep up with the massive quantities of shit that we stuff into our faces daily.
So as the bowels back up there is no where for this sticky snot to go but into our bloodstream, where it is deposited in the nearest place possible. It builds up in the joints (arthritis). It comes out of the skin as acne or rashes. It comes through the scalp as dandruff. It comes out the nose as snot and buggers. It comes out the chest as a cough, the glands as sore throat, etc, etc.
This is why during a cleansing diet it is so important to cleanse the bowels at least every other day with enemas or at least once a week with colonics.
Our body is continually attempting to rid itself of this disease matter and when we help it along with a cleansing, detox diet, masses head for the exit. So if we don't assist the bowels in releasing these masses, we run the risk of allowing these poisons to back up in the bowels even more and showing detox sympoms, runny nose, coughing up phlem, rashes, headaches, swollen joints, all the symptoms associated with a normal modern day lifestyle. This is why so many people fail when they first attempt to eat right. The new cleansing alkaline food supply begins to clean the blood which begins to clean all of this foreign matter from the tissues and the body in its infinite wisdom sends it back to the bowels for release. But the bowels are still so caked with old crap that they need a lot of help.
When Natalia says "awaken and release" she is being literal. This fresh hydrating alkaline food that we are now consuming awakens the acidic masses of waste we are retaining and releases it through the urine and the bowels.
If you are not expelling mass quantities through these two exit points you are not detoxing.
People think I am crazy when I say that following this lifestyle properly makes you immune to communicable diseases, but it is true.
