A 2-year study published in the Annals of Internal Medicine has concluded that a glass of red wine a day can manage cholesterol and improve cardiac health for those patients with Type 2 Diabetes.
Of course, this is not new since moderate consumption of red wine has been linked to an improvement in mortality and cardiovascular rates.
While there is evidence between the absence of Type 2 Diabetes among moderate drinkers, this was controversial due to the lack of long-term randomized studies.
This led to researchers from Ben-Gurion University to research whether red or white wine could improve glucose control which depended on genetic profiling as well as alcohol metabolism. Until now, ethanol has been considered to be key to these benefits which meant that all drinks including wine were equally beneficial.

What they wanted to find the cardiometabolic effects involved with Type 2 Diabetes patients when they drank moderate amounts of alcohol. Also, they wanted to check as to which type of alcohol could offer the best results.
Before the study began with 224 Type 2 Diabetes patients who abstained from alcohol, they hypothesized that moderate wine consumption would lower cardiometabolic risk.
People who were excluded were those having more than one alcoholic drink a week, a history of addiction or even those taking two or more insulin injections a day.
Between June 2010 to May 2012, these patients were given either mineral water, red or white wine with dinner. The Mediterranean Diet was stricly followed throughout this time period.
Apart from this, blood sample, group sessions and questionnaires were attended and completed.
While there were no material differences between the groups, the ones which consumed wine slept better as well as a decrease in cardiometabolic risk. In fact, it was the group of red wine drinkers that saw a significant change in lipid variables.
Also, while alcohol tends to assist in glycemic control, red wine has a much stronger effect on lipid levels as well as overall variables of the metabolic syndrome.
Still, despite the findings, the authors mention that the benefits involved with drinking red wine must be weighed against the risks if this translates into clinical practice.
