We’ve all heard this concept at some point or another, but now, someone is ready to back it up — with science! A study completed by Ben-Gurion University shows that a glass of wine each night has long-term benefits to your health. A two-year, randomized controlled trial led by researchers found ​a glass of red wine every night helped people with type 2 diabetes manage their cholesterol and cardiac health. The study also shows that both red and white glass of wine can improve sugar control, depending on alcohol metabolism-genetic profiling.

In the study titled, “Effects of Initiating Moderate Alcohol Intake on Cardiometabolic Risk in Adults With Type 2 Diabetes,” the researchers aimed to assess the effects of initiating moderate alcohol consumption in diabetics and sought to determine whether the type of wine matters. The findings showed that red wine was found to be superior in improving overall metabolic profiles, and it improved health mainly by modestly improving the lipid profile, by increasing good (HDL) cholesterol and apolipoprotein A1, while decreasing the ratio between total cholesterol and HDL cholesterol. The  researchers also found that only the slow alcohol-metabolizers who drank wine achieved an improvement in blood sugar control, while fast alcohol-metabolizer did not benefit from the ethanol’s glucose control effect. Both red and white wine had no effect in the participants’ blood pressure, liver function tests, adiposity or adverse symptoms, though it did significantly improve participants’ sleep quality.

The overall conclusion from the research conducted implies that “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.”
