Red wine consumption improves insulin resistance but not endothelial function in type 2 diabetic patients
I just recently ran blood-work on a patient that drinks red wine on a consistent basis and she has a beautiful triglyceride/HDL ratio. My gut feeling is that the red wine she drinks is a factor in her lowered insulin resistance.
The amount consumed daily in this study was 360 ml, which is about a half bottle of wine per day.
