Back to blackcurrants

In Blackcurrent by James Anstee

A blackcurrant extract improves glycaemic control and insulin sensitivity, according to a new study first from Liverpool John Moores University. It showed that taking the New Zealand blackcurrant extract, CurraNZ, could be the answer to effective, simple health management to help dramatically reduce the risk of developing Type 2 diabetes, by improving insulin resistance by 22%. It, therefore, has the potential to tackle obesity.

The new research suggests that a potent polyphenol group of compounds, anthocyanins, found in New Zealand blackcurrants and dietetically wrapped into a proprietary complex called Enzans and which are in CurraNZ capsules, offers the chance to ward off developing T2D and the health risks of pre-diabetes.

In the new study, short-term, but not acute, intake of New Zealand blackcurrant extract CurraNZ improved insulin sensitivity and free-living postprandial glucose excursions (sugar spikes post a meal) in overweight/obese individuals. The study published in European Journal of Nutrition investigated the effect of repeated daily intake of New Zealand blackcurrant anthocyanins on metabolic responses in sedentary obese and overweight individuals under ‘free living’ conditions.

Dr Sam Shepherd, Senior Lecturer in Sport and Exercise Nutrition, who led the study, said, “These latest research findings are really exciting, with the potential of New Zealand blackcurrant extract to have an even greater effect in unhealthy people and those with Type 2 diabetes. We know that exercise and specific diets can improve insulin sensitivity and reduce the risk of Type 2 diabetes, and CurraNZ provides another approach. The big difference is its implementation, as unlike exercise and diet, taking two blackcurrant capsules a day doesn’t require a lot of effort from the user.”

CurraNZ is a high-potency natural New Zealand blackcurrant extract in a capsule, each containing the equivalent of a generous handful of fresh blackcurrants. Each pack of CurraNZ contains 30 capsules and is available at curranz.com for £21.75 (£1.45p per day if taking two capsules as recommended).
