Abstract
Although potent antimicrobial agents may effect rapid and significant changes in fecal microflora, changes in diet or dietary supplements usually produce modest changes by comparison. It may be, however, that even such minor changes may result in significant changes in metabolic activity, particularly in terms of production of possible carcinogens or cocarcinogens. It is clear that significant changes may occur in metabolic activity without major qualitative or quantitative changes in the fecal microflora. Other research that might help explain the epidemiological observations of the association between diet and colon cancer would be studies of the flora at different levels of the gastrointestinal tract (particularly the cecum and small bowel), studies of the mucosa-associated flora at different levels, and long-term dietary studies.
