I am interested on the effect of dietary constituents such as fibre and antioxidants (polyphenols), on metabolic responses including glucose, lipid metabolism, and gastrointestinal and adipokine secretion in healthy individuals and in individuals with the metabolic syndrome or with metabolic-related increased oxidative stress. The methodological approach is by conducting human dietary interventions on free-living subjects. We have shown that insoluble dietary fibre rich in polyphenols modulates postprandial responses to ghrelin, an orexigenic gut peptide, and modifies substrate utilisation by increasing lipid oxidation, indicating potential beneficial effects of fibre and polyphenols in the management of metabolic syndrome, however further investigation is needed before recommendations are provided.
