After you change your eating habits from poor diet to nutritionally beneficial, toxins must come out. If you have lived on sugar, caffeine, alcohol, processed foods, animal products and low intake of plant fresh foods, your body will have toxins. That is the absolute bottom line. If toxins are not released from your cells, nutrients will not enter the cells (because like anything, cells can only hold so much) and therefore the body never fully benefits even if your diet has been improved and the foods you take in are highly nutrious.
During colonic irrigation, you will release poisons and toxins from your colon, from your liver and from you blood. Nutrition is only half the therapy. Detox is the other half. We have to get the toxins out to allow the nutrients to get into the tissues.
