A glass of wine every day can improve cardiac health, help manage cholesterol and foster better sleep for people with type 2 diabetes, says a new study.
The study involved 224 participants with type 2 diabetes. The findings of the study were put down to the healthy antioxidants in dark grapes called phenols- the most well-known of which is resveratrol.
AdvertisementProf Iris Shai, of the Ben-Gurion University of the Negev in Israel, said, "The differences found between red and white wine were opposed to our original hypothesis that the beneficial effects of wine are mediated predominantly by the alcohol. However both red and white wine improve sugar control among those carrying genes that helped them to metabolize alcohol slowly."
The study was aimed to assess the effects and safety of initiating moderate alcohol consumption in diabetics and sought to determine whether the type of wine matters.
Diabetics are more susceptible to developing cardiovascular diseases and have lower levels of good cholesterol.
"Red wine was found to be superior in improving overall metabolic profiles. Initiating moderate wine intake, especially red wine, among well-controlled diabetics, as part of a healthy diet, is apparently safe, and modestly decreases cardio-metabolic risk. The differential genetic effects that were found may assist in identifying diabetic patients in whom moderate wine consumption may induce greater clinical benefit," said Shai.
Through genetic tests the study participants were identified whether they are fast alcohol-metabolizer or slow alcohol-metabolizer. One in five participants were found to be a fast alcohol-metabolizer.
The study found that only the slow alcohol-metabolizers who drank wine achieved an improvement in blood sugar control while fast alcohol-metabolizers did not.
Red and white wine did not have any effect on blood pressure, liver function, adiposity or adverse events or symptoms. However, the sleep quality was significantly improved in both wine groups.
"The genetic interactions suggest that ethanol plays an important role in glucose metabolism, while red wine's effects additionally involve non-alcoholic constituents. Yet, any clinical implication of the CASCADE findings should be taken with caution with careful medical follow-up," said Shai.
