Introduction

It has been described that dietary fibers (DF) could have favorable effects in the control of subjective feelings related to appetite/satiety, property that in the current epidemiological context could be beneficial. Objective: to evaluate the acute effect of 3 types of DF on the subjective perception of feelings related to appetite/satiety.

Material and Methods

Randomized, double-blinded, controlled, crossover study. 21 healthy subjects with body mass index between 18.5-24.9kg/m2 were randozomized to consume 4 separate breakfasts for at least 2 days. The breakfasts were fortified with 3 g of: oat β-glucan (BETA), apple pectins (PECT), microcrystalline cellulose (CELL) and maltodextrin as control (MALT). The subjective feelings of appetite/satiety were determined with a Visual Analog Scale (VAS) before breakfast and at 15, 30, 60, 90 and 120 minutes.

Results

In analysis of variances (ANOVA) showed a significant difference at 15 minutes (p<0.05) in the perception of satiety of breakfast fortified with apple pectin versus oat β-glucan. Oat β-glucan produced the least effect on subjective satiety (p <0.05). An ANOVA of repeated measures did not show effects of the types of fibers added to breakfast on the subjective feeling of appetite.

Conclusions

Apple pectins appear to be more effective than other types of DF to increase the subjective perception of satiety and decrease appetite, especially in the early postprandial period.
