wine-benefitsPeople with diabetes are at an increased risk for developing cardiovascular disease and can often have lower levels of  high-density lipoprotein cholesterol (HDL-C) or "good" cholesterol. 

One potential theory to increase HDL is to drink moderate amounts of wine. Researchers in Israel put this theory to the test when they tested 224 patients with type 2 who were alcohol-abstaining particpants. They also sought to determine if the type of wine consumed mattered. They randomly assigned the patients with well-controlled type 2 diabetes to drink 150 mL of mineral water, white wine, or red wine with dinner for two years and then measured lipid and glycemic control profiles, as well as other cardiovascular measures and quality of life. All participants were also encouraged to follow a Mediterranean diet without caloric restriction.

After two years, patients who drank wine had decreased cardiometabolic risks compared to patients who drank mineral water. The red wine drinkers experienced the most significant changes in lipid variables, suggesting the potential synergy of moderate alcohol intake with specific nonalcoholic wine constituents. This group increased their HDL-C level by 0.05 mmol (2.0 mg/dL).

It is important to note, there are other ways to treat cholesterol levels, and for some, drinking wine may not be appropriate or beneficial.
