“…The viscosity of fibers has also independently been shown to affect food intake and this effect may be mediated by alterations in satiety hormone release. In a double-blind randomized, controlled and crossover trial, PGX preload significantly reduced ad libitum pizza intake in adolescents compared with two lower viscosity fibers (glucomannan and cellulose) (Vuksan et al, 2009). …”

Background/Objectives: A variety of dietary fibers have been shown to alter satiety hormone gene expression and secretion. The objective of this study was to examine plasma satiety hormone concentrations in healthy subjects consuming either PolyGlycopleX (PGX) or control (skim milk powder) for 21 days. Subjects/Methods: A randomized, double-blind, placebo-controlled clinical study was conducted in 54 healthy male and female adults. Participants consumed 5 g per day of PGX or control for 1 week followed by 2 additional weeks of 10 g per day of assigned product (n ¼ 27 per group). Primary outcomes measured at three visits (V1, V2 and V3) were plasma active glucagon-like peptide-1 (GLP-1) total ghrelin, peptide YY (PYY) and insulin.Results: There was a significant effect of visit for fasting PYY with control participants experiencing decreased PYY levels over time while PGX prevented this decline. When stratified by body mass index (BMI), PGX increased fasting PYY levels from week 1 to week 3 compared with control in participants with BMI o23 kg/m 2 . There was a significant effect of visit for fasting ghrelin with levels decreasing in both PGX and control groups over time. No differences were detected in fasting GLP-1 levels. Although there was a 14% reduction in fasting insulin between V1 and V3 with PGX this was not significantly different from control. Conclusions: PGX is a highly viscous, functional fiber that modifies satiety hormone secretion in healthy adults. Its' potential to act similarly in overweight adults warrants investigation.

“…Recently, the contribution of fibre viscosity to satiety has received attention. Vuksan et al (2009) tested the effects of three fibres (consumed in 5g portions dissolved in a beverage) that differed only in terms of their ability to thicken liquid and found that only the most viscous fibre reduced intake at the next meal. Similarly, Juvonen et al (2009) examined the effects of an oat-fibre beverage with or without its natural viscosity (achieved by b-glucanase treatment) and found that the higher viscosity beverage slowed gastric emptying and reduced satiety hormone responses compared to the lower viscosity beverage, leading to lower total energy intake over the course of the day.…”

“…Moreover, evidence is mixed for gastric emptying times varying according to fibre viscosity (Marciani et al, 2000;Wanders et al, 2011) and dilution in the stomach means that differences in oral viscosity may not be reflected in gastrointestinal viscosity. Besides, the perceived viscosity of fibrous foods could be critical to their appetite suppressing effect (Juvonen et al, 2009;Vuksan et al, 2009).…”

Foods that generate strong satiety sensations have obvious benefits for weight management. This review builds on the understanding that a food's satiating power is dependent on the amount of protein, carbohydrate, fat and fibre it contains by examining evidence that the consumer's sensory and cognitive appraisal of the food is also important. It is concluded that numerous features of a food product can be manipulated to enhance the consumer's experience of satiety but the combination of these features will ultimately determine its effect on appetite control. Taking this integrated approach to satiety will optimise the development of high satiety foods.

“…Our recent study demonstrated signifi cantly lower food intake after the high-viscosity fi ber blend preload compared with the medium viscosity glucomannan and low viscosity cellulose fi ber preloads in healthy-weight adolescents [54]. Changes in appetite corresponding to viscosity levels also were observed in a study by Mattes and Rothacker [50], in which hunger ratings were signifi cantly lower after ingestion of the more viscous beverage and remained lower than baseline for a longer period of time.…”

In randomized controlled trials, viscous soluble fibers have demonstrated acute and long-term metabolic improvements in type 2 diabetes, such as reductions in hemoglobin A1c, fasting and post-prandial glycemia, insulinemia, and cardiovascular risk factors. In addition, they may be helpful in weight control through promoting feelings of fullness. Increasing consumption of foods containing fiber or use of fiber supplements could play an important role in managing diabetes with positive outcomes on vascular complications and reduced cardio-vascular disease risk.
