A new research done by Dr. Mark Willems, from the University of Chichester, and collaborators has led to the conclusion that regular intake of New Zealand blackcurrant extract can help blood sugar levels to return to normal levels more quickly in type-2 diabetes sufferers.Their conclusion is based on a 7-day trial during which healthy participants from both sexes had to ingest 6 grams of NZ blackcurrant extract per day (Every 6 g of the serving contained 138.6 mg anthocyanins, 49 mg vitamin C, and 5.2 g of carbohydrates with total phenolic content 271.6 mg). The participants did an oral glucose tolerance test (OGTT) before (day 0) and seven days later (day 7) to assess their levels of fasting blood glucose and insulin response. For the OGTT, the participants had to drink 75 g of glucose dissolved in 250 ml of water. Blood samples were then taken from all participants at every 30 minutes up to 120 minutes after they had drunk the glucose drink.Dr. Williems and collaborators detected that those participants who had taken NZ blackcurrant extract during the 7-day trial had faster insulin response; hence, lower fasting blood glucose levels. This is the first study that demonstrates the effects of a high-anthocyanin berry fruit on increasing insulin response. The results are strong support of the marvelous potential of New Zealand blackcurrant to control blood sugar levels in Type-2 Diabetes sufferers.
