Not farting at all in a day is not good news: gas is the best sign for assessing the microbiota

Recent studies suggest that having 1 to 3 bowel movements a day is the usual pattern for healthy digestion.

Constipation appears linked to protein fermentation and higher blood levels of toxins such as p-cresol sulfate and indoxyl sulfate.

Intestinal gas is often a sign of an active microbiota fermenting fiber, not necessarily a problem.

Bacteroides, Ruminococcus, and Roseburia are among the microbes associated with this fiber-fermenting activity.
