Dr. Burkitt\ufffds conclusions were based upon the stool transit time of the two populations. Stool transit time is the amount of time it takes for food to enter the mouth and then exit the body; He observed that native Africans had an 18-24 hour stool transit time. On the other hand, the British naval officers\ufffd wives\ufffd stool transit time was 48 hours to one week. Dr. Burkitt also observed that the average weight of the natives\ufffd stool was approximately 16 ounces. At the same time the British naval officers\ufffd wives\ufffd stools averaged only 5 ounces. Burkitt eventually concluded that the naval officers\ufffd wives suffered from a long list of degenerative diseases because of a toxic bowel that resulted from a lack of fiber in their diet. The native Africans managed to avoid these diseases because they had healthy digestive systems as a result of their high fiber diet.thanx,
