Summary

Postprandial glycaemia refers to the transient rise in blood glucose levels that occurs after consuming a meal. Large fluctuations in blood glucose levels, experienced on a frequent basis, may impair the functioning of pancreatic beta cells, and thus elevate the risk of developing type 2 diabetes mellitus (T2DM) and cardiovascular disease. Our group has previously shown that consuming a drink containing fruit polyphenols immediately before a meal, may reduce postprandial glycaemia. Importantly, other fruit components, namely soluble fibres, also impact on carbohydrate digestion by slowing gastric emptying rates. Combining fruit polyphenols and fibre in a drink may, potentially, have additive or synergistic effects on reducing postprandial glycaemia.

This study will investigate the effects of drinks containing blackcurrant polyphenol extract combined with pulp (source of fibre), and pulp alone, on postprandial outcomes and cognitive function following a mixed carbohydrate (starch and sucrose) test meal.
