Dietary fiber is a term that includes the edible parts of plants or analogous carbohydrates resistant to digestion and absorption in the human small intestine with complete or partial fermentation in the large intestine. Functional fibers are isolated, non-digestible carbohydrates which have beneficial physiological effects in humans. Total fiber is the sum of dietary and functional fiber. Dietary fiber is important for human beings because it is associated with a normal gut microbiota. Gut microbes act upon dietary fiber to produce metabolites like short-chain fatty acids, which may be absorbed into the circulation and are thought to affect metabolic regulation processes. These fatty acids may also be a substrate for other gut microbes.
Although increasing dietary fiber intake is a general recommendation for overall health as well as for constipation, there is a 30-year debate and strong controversy about the scientific evidence of its clinical benefits and about the type and amount of fiber to be prescribed in each case. This document analyzes the evidence about the types and mechanism of action of dietary fiber for managing constipation. We propose an algorithm of steps clinicians must have in mind when prescribing fiber supplements for people with type 2 diabetes mellitus with constipation.
