text: is it possible to consume a diet so that you never have to defecate? when we defecate, we are getting rid of waste.  stuff your body does not need.  is it possible to eat a diet of perfectly nutritious foods, that is, food that can be 100% used by your body, so you never have to poop again?  ...not planning to do it, just curious. maybe you don't think of it as important, but defecating is as important as breathing, or your heart beating.  our bodies are amazing biological systems and elimination of wastes is very important.  asimilation of nutrients from food is important to sustain life.  with the proper diet, beneficial bacteria thrive in our bowels.  this flora is important for our health.  this flora help and support with : digestive process by helping digest lactose (milk sugar) and protein, clean the intestinal tract, purify the colon, and promote regular bowel movements, create lactic acid, which balances intestinal ph, produce antibiotics and antifungals that prevent the growth of harmful bacteria and fungi, provide a passive mechanism to prevent infection, contribute to the destruction of molds, viruses, and parasites, protect us from environmental toxins such as pesticides and pollutants, reduce toxic waste at the cellular level, and stimulate the repair mechanism of cell, manufacture vitamins b6, b12, k, folic acid, and assorted amino acids, help maintain healthy cholesterol and triglyceride levels, break down and rebuild hormones.  the best diet would be the one that incorporate enough fiber for the intestinal floral to do its thing and increased transit time, so you actually poop more frecuently... which in fact would be more 'healthy' for you.
