When some environmental pollutants are ingested into the human body, they can produce toxic substances in the intestine, such as dibutyl hydroquinone, amaranth, certain carcinogens (such as nitrite) and certain heavy metals (such as Pb, Cd) , Hg, high concentrations of Cu, Zn, etc., dietary fiber has the function of accelerating its excretion and detoxification. Dietary fiber can speed up intestinal peristalsis, accelerate the excretion of toxic substances, and thus produce detoxification. Therefore, dietary fiber can be used as the last barrier of certain environmental pollutants to prevent them from harming the human body, so it is also called "natural detoxifier".
