Dietary Fiber and Colon Function in a Population Aged 18–80 Years

It has been suggested that a range of diseases may be linked to the intake of dietary fiber (Burkitt and Trowell, 1975). This hypothesis has been examined in a number of ways, but rarely in a normal population. In this study fecal constituents have been measured in a defined population aged 18–80 and the association of fecal constituents with age, diet, and serum lipids investigated.
