Effect of Three Fibres on Glycaemic and Insulinaemic Responses in Healthy Adult Volunteers

Randomised, Single-blinded, Controlled, Crossover and Acute Clinical Intervention to Assess the Effect of Three Fibres on Glycaemic and Insulinaemic Responses in Healthy Adult Volunteers

The purpose of this study is to determine whether DuPont Experimental Dietary Fibre products 1 and 2 are digested using glycaemic and insulinaemic response as markers.

DuPont Experimental Dietary Fibre products 1 and 2 glycaemic and insulinaemic response will be compared against that of polydextrose and dextrose when given to adult healthy volunteers.
