Stools that sink like lead are a warning sign. If your stool floats score a point for the presence of fiber and adequate fluids. Shape is part of the language of the bowel too. Pencil shaped, string bean and rabbit food pellets are red flags signaling warning. These shapes indicate constrictions and impaction in the colon.
Noxious fumes indicate putrefying matter is homesteading in the bowels.
The worst smelling stools belong to meat eaters, consumers of grease and fats and highly refined foods and sugars. These foods tend to stay longer, and sometimes permanently in the intestinal track where they decay, putrefy and poison the body. Get over the idea that your bowels are dirty, or that the anus and rectum are the only parts of your body that are nasty and disgusting. Every part of you is perfect, every part of you is part of an extraordinary design. Give your body what it needs, and it will serve you well as the energy amplifying, fully integrated, self-regenerating, divinely planned organism it truly is.
