Summary

This research is aimed at determining whether the presence of oleuropein in olives (Olea europaea L.) has any lowering effect on post-prandial blood glucose levels. Volunteers will be required to consume commercially available olives together with white bread, and their glycaemic response will be measured. The blood glucose response of bread will be determined initially as a control/reference. Food samples and control will be consumed in random order.

The recent rise in the cases of Diabetes mellitus in both children and adults has raised a concern for the need to proffer immediate solutions amongst scientists in the fields of medicine food science and nutrition. One of the approaches of reducing postprandial hyperglycaemia and high glucose spikes is to impede digestion and absorption of starch. This is potentially achieved through the inhibition of the activities of starch digesting enzymes namely alpha amylase and alpha glycosidase. There are currently some antidiabetic drugs such as acarbose and miglitol which have been quite efficient in these inhibitory functions but not without associated side effects and complications such as liver toxicity, etc, arising from to long term usage of such drugs. It therefore becomes imperative for natural substitutes from food sources to be explored as better alternatives. At the moment several plant foods are under investigation as suitable alternatives, and olives appear to be quite promising in this regard. There are quite a few studies that have reported the inhibitory activities of olives oleuropein on alpha amylase in vitro but information on in vivo testing is very scarce.

It is expected that the research outcome will be a gateway to the reduction and control of the incidence of diabetes mellitus.
