A two-year study on moderate intake of wine in diabetic patients showed that red wine helped in controlling blood sugar and reduction of cholesterol.
The study conducted by Ben Gurlon University of Negev-Soroka Medical Centre and Nuclear Research Centre in Israel analyzed the results from 224 diabetic patients who all abstained from alcohol. In the controlled study, patients were given 150 ml of white wine, red wine or mineral water during dinner time. All followed a Mediterranean diet, however, there were no restrictions on caloric intake.
The results showed that red wine decreased total cholesterol, while both wines helped in controlling fasting blood sugar, insulin resistance and hemoglobin A1c. Further, the scientists noted that sleep quality was better in wine groups compared to water group. There was no much difference in blood pressure, liver function or quality of life in the three groups.
The study funded by the European Foundation for the Study of Diabetes concluded that ethanol has a key role in glucose metabolism, and red wine intake has impacts from its non-alcoholic constituents.
Red wine contains more tannin than white wine and it is usually produced from black grapes. Grape skins along with pulp are used for red wine preparation and the red color comes from the skins.
