Light drinking may be beneficial in type 2 diabetes: Further research needed -- ScienceDaily
The authors found ten relevant RCTs involving 575 participants that were included in this review. Meta-analysis showed that alcohol consumption was associated with reduced triglyceride levels and insulin levels, but had no statistically significant effect on fasting blood glucose levels, glycated haemoglobin (HbA1c, a measure of blood glucose control), or total cholesterol, low density lipoprotein (bad) cholesterol, and high density lipoprotein (good) cholesterol.
Subgroup analysis indicated that drinking light to moderate amounts of alcohol decreased the levels of triglycerides (blood fats) and insulin in people with T2DM. Light to moderate drinking was defined by the authors as 20g or less of alcohol per day. This translates to approximately 1.5 cans of beer (330ml, 5% alcohol), a large (200ml) glass of wine (12% alcohol) or a 50ml serving of 40% alcohol spirit (for example vodka/gin).
