Positive effects of bread enriched with a-cyclodextrin or a compound of hydroxytyrosol encapsulated in a-cyclodextrin on postprandial glucose, insulin and appetite responses of healthy subjects.

Abstract

Rationale: Attenuation of postprandial blood glucose and insulin levels is a beneficial health effect. Alpha-cyclodextrin (a-CD) is a dietary fiber known for its beneficial effects on the reduction of postprandial glycaemic responses. Hydroxytyrosol (HT) is a phenolic compound with antioxidant and antidiabetic effects. Enrichment of bread with a-CD or a compound of HT encapsulated in a-CD was performed to examine potential postprandial benefits.
