What are fibres?
Carbohydrate polymers with a Degree of Polymerisation (DP) of 3 or more
Resistant to absorption and human enzymes in the small intestine
Have a beneficial physiological effects
5
“Fibre” means carbohydrate polymers with three or more monomeric units, which are neither digested nor absorbed in the human small intestine
Fibre ingredients should also have a beneficial physiological effect(2) demonstrated by generally accepted scientific evidence
(1) Directive 2008/100/EC, Annex II published 29th October 2008;; (2) such as: decrease intestinal transit time, increase stool bulk, is fermentable by colonic microflora, reduce blood total cholesterol, reduce blood LDL cholesterol levels, reduce post-prandial blood glucose, or reduce blood insulin levels,....; Also repeated in Commission Guidance methods of analysis December 2012

Decreased energy intake after consumption of polydextrose
Systematic review and meta-analysis to examine the effects of polydextrose on energy intake at an ad libitum lunch
6 studies were identified with data for a total of 120 subjects
Energy intake at a subsequent ad libitum lunch indicates a significant effect of polydextrose in a dose-dependent manner over the placebo (p < 0.01)
Energy intake for the rest of the day or dinner and the total daily energy intake were not statistically significant
