Eating enzymes can not only improve the body’s immunity, but also stimulate the intestinal peristalsis and help the discharge of feces in the intestine. The dietary fiber in the enzyme will stimulate intestinal peristalsis when it is digested in the intestinal tract. After the intestinal peristalsis increases, a large amount of gas will be produced, especially hydrogen sulfide, so the gas discharged is smelly. Some people will be constipated and there will be a large amount of feces in their intestinal system.
