Psyllium fecal bulk effects

Fiber derived from psyllium seed has a long history of use as a pharmaceutical to produce laxatlon. It s high bulking properties are due to its high content of hemlcellulose. When incorporated into food products and fed to humans, it produces the desirable effects of increased stool bulk, decreased fecal transit time, and decreased blood serum cholesterol and triglyceride levels. However, concurrently psyllium fiber supplementation results in some depression in aljsorption of selected minerals, fat and protein. This was also true of some but not all of the other fiber sources tested.
