Although dietary fibre is generally thought to protect against the development of colorectal cancer, some of the results of animal and epidemiological studies are equivocal. We believe that this may be because the term dietary fibre covers a range of complex materials and some may protect but others

Dietary fibre has a complex and highly variable composition. Although some dietary fibres may protect against colorectal cancer, it is unlikely that all are equally protective. Dietary fibre is principally composed of plant cell walls, but it also includes components obtained from cell walls (e.g.

Epidemiology and animal experiments indicate that dietary fibres protect against the development of colorectal cancer. However, insoluble dietary fibres appear to be more effective than soluble dietary fibres and one mechanism by which they may protect is by adsorbing dietary carcinogens. We found

It is often recommended that consumption of dietary fibre should in increased to protect against colorectal cancer. However, although more than 95% of dietary fibre is contributed by whole plant cell walls, very little experimental work has been done using whole plant cell walls. These may protect

The dietary fiber (DF) hypothesis suggested that DF, as plant cell walls, protected against colorectal cancer. The implicit assumption in much historic literature was that the readily analyzed and quantified nonstarch polysaccharide (NSP) component was critical in cancer protection. However, the

Dietary fibre (DF) is widely considered to protect against cancer, especially colorectal cancer. However, a large prospective epidemiological study has shown no apparent effect of DF intake on the development of colorectal cancer. We suggest that this may be because the term DF represents a wide
