[Intestinal transit time in Togo (Western Africa) and Germany].

In five groups of Africans and Europeans in Togo (West-Africa) and Germany intestinal transit time and stool-weights have been studied. Native Africans on traditional food passed three times more stool (307 g/d) in half of the time (33 hours) as Europeans and Africans on Western diet did. The effect of dietary fibre on intestinal transit time and intestinal pathology is stressed.
