Dietary Fiber Intake and Colon Cancer Mortality in The People’s Republic of China
Abstract
There are many unresolved questions concerning the relationship between dietary fiber and cancer of the large bowel. These include (1) inadequate knowledge of the physiological activities of the various dietary fiber constituents, (2) uncertainties about the food composition of these constituents, (3) variable constituent content for the same food grown in different geographic regions and at various stages of harvest, and (4) uncertainties about earlier intake levels of various fiber-containing foods during the time when cancers were forming. It would therefore appear to be inappropriate to put too much emphasis on the effects of individual fiber fractions not only because of these uncertainties of intake but also because the intakes of individual fiber fractions are strongly correlated with each other. Moreover, fiber intakes also correlate with many other dietary constituents that may be associated with the prevalence of large bowel cancer.
