Why is human excrement smelly? Of course, we are not saying that only human excrement is foul, and animal excrement is no exception. However, why is this?

Furthermore, is the conventional belief that feces are useless or harmful? Don't worry, this article will answer these questions one by one, hoping that everyone has a new understanding of excreta.

Because there are many people in Public toilet, you can obviously smell a bad smell when you go in, especially some Public toilet that are not cleaned in time. Why on earth? Why must the secretions discharged from the human body have a foul odor? Regarding this issue, we need to start with the composition of feces.

Normally, the components in feces can be classified into 6 categories:

everythingFood residue that has not been fully digestedSuch as starch granules, meat fibers, plant fibers, etc; Secondly, although completely digestedChyme that has not been fully absorbed; The third is bile pigments, enzymes, mucus, etcGastrointestinal secretions;

The fourth is indigo matrixSkatoleFatty acids, etcDecomposition product;Cells detached from the intestinal wall;,Escherichia coli, Enterococcus, etcEtc.

In addition, if too much protein rich food is consumed, undigested protein remains in the intestine, which undergoes anaerobic decomposition under the action of intestinal bacteria, producing many harmful substances such as aminesIndole, hydrogen sulfideEtc.

Indole, hydrogen sulfide,,

It is precisely because of this odor that many people avoid discussing it,But some people's concerns are quite peculiar. Human excrement is foul smelling. Why did some ancient people still eat it without being harmful to their bodies?

Some ancient people attempted to eat excrement with a purpose, such as Yu Qianlou's attempt to help determine what kind of disease his father was suffering from.

In fact, it is not just the ancients. Recently, the Food and Drug Administration (FDA) approved a kind ofOral medication VowstHas refreshed our understanding,Fecal matter may normally be referred to as a 'life-saving drug'.
