You've been talking a lot about messed-up colons, and I can certainly relate to some of the signs of toxicity you mentioned. What I would like to know is, what are the characteristics of a healthy, well -functioning colon?
Healthy babies, animals and adults not subjected to the "refinements" of civilization (i.e. aboriginal peoples) have bowel movements shortly after each meal is eaten. So, assuming there is sufficient fiber and water available to the colon, one characteristic is a bowel movement shortly after a meal is eaten. Once the urge to eliminate is honored by a trip to the toilet, the elimination should be easy and take no more than a few seconds. The stool will be long, large in diameter, light brown in color, without offensive odor and should float or sink very slowly. When the toilet is flushed, the stool immediately begins breaking apart by the action of water movement. As incredible as this may sound, it is true and commonly experienced in cultures where people live more naturally.
