Red wine polyphenols show blood sugar benefits
Polyphenols from wine may improve glucose metabolism in men at high risk of heart disease, suggests a new study from Spain.
A daily glass of red wine or dealcoholized red wine for four weeks was associated with a significant improvement in glucose metabolism, as measured by insulin resistance, according to findings published in Clinical Nutrition .
“In our study both red wine and dealcoholized red wine improved insulin sensitivity which, together with prior findings, suggests that both ethanol and polyphenols are responsible for this beneficial effect,” wrote researchers from the University of Barcelona and the University of Valencia in Spain.
