The relationship between bowel cancer and fiber content in the diet.Am J Clin Nutr. 1978 10; 31(10 Suppl):S248-S251.AJ
Colon cancer, very rare in rural South African blacks, is also rare in urban dwellers despite considerable rise in prosperity. The disease has scarcely increased during the last quarter of a century. The same situation applies to appendicitis. Endeavors to characterize different black populations in transition (including subjects who have had appendicitis) are being made respecting 1) diet, especially dietary fiber intake; 2) bowel physiology (e.g., transit time); 3) concentrations of fecal bile acids and other metabolites; and 4) the activity of certain fecal enzymes.
