What can a glass of red wine a day do in Type-2 Diabetes?

Red wine has been a major subject of various health debates for years now. What are the benefits? What are the health risks? Is a glass of red wine a day really healthy? So many studies and so many opinions. Apparently, it all depends!

As stated by many studies, a glass of red wine a day can have various effects on the human organism. Usually, it depends on the sex, age and the health condition of the drinker. The evidence is mixed and still confusing.

However, according to a new study, which used a randomized controlled trial to examine the effects of drinking red wine, having a glass a day at dinner can improve the heart’s health in patients with diabetes.

The researchers at the Ben-Gurion University of the Negev in Israel have chosen a very specific group of participants: they had to be 40 to 75 years of age, had to have stable diabetes (but not more than 2 insulin injections per day), non-smokers, with no history of any heart-related problems. The participants were randomly assigned to either a glass or red wine, white wine or water at dinner.

Researchers have followed the patients for as long as 2 years (which is probably the longest study when it comes to wine). The results of the study were indeed quite surprising – participants who drank red wine showed 2 mg/dL rise of the HDL (good) cholesterol, compared to whine wine and water drinkers.

Both white wine and red wine drinkers reported to sleep better, compared to participants who drank water. Moreover, participants with slower metabolism (in particular those whose bodies take more time to break down alcohol) had decreased their morning insulin levels. Meanwhile fast metabolizers have shown significant improvements in blood pressure.

In the end, the authors of the study believe that if your diabetes is well under control, a glass of red wine at dinner will cause no harm and might even lower the risks of heart problems.
