Why does poop smell so horrible when all it's only digested food?
Human feces is digested and undigested food. It is also human waste
from the body such as dead blood cells and other toxins. It
normally consists of about 66% digested and undigested food and
about 33% live bacteria. This gives it its foul odor and it is
crucial that you wash your hands afterward because this bacteria
can make you very ill if ingested.
