Blackcurrants have a beneficial effect on post-meal glucose response, and the required portion size is much smaller than previously thought, a new study from the University of Eastern Finland shows.
Blackcurrants have a beneficial effect on the blood glucose response after a meal. They balance the glucose response of ingested sugar by attenuating its rise and delaying its fall. The effect is likely associated with berry-derived polyphenolic compounds, anthocyanins, which are rich in blackcurrants.
The beneficial health effect of blackcurrants was supported by a recent study conducted at the University of Eastern Finland. In the clinical meal study (Maqua) the beneficial effect on postprandial glucose response was achieved by 75 g (1.5 dL) of blackcurrants, a remarkably smaller portion size than in earlier studies. Blackcurrants are often consumed with added sugar because of their natural sourness, which may be a cause of concern for health-conscious consumers. However, it seems that
