(HealthDay News) — Wine is associated with a greater decrease in the risk for type 2 diabetes than beer or spirits, according to a review published in the Journal of Diabetes Investigation.

Jin Huang, PhD, from the Huazhong University of Science and Technology in Wuhan, China, and colleagues conducted a systematic review and meta-analysis to examine the relationship between intake of specific types of alcoholic beverages and incidence of type 2 diabetes. Data were included from 3 prospective cohort studies, with 397 296 study participants and 20 641 cases of type 2 diabetes.

The researchers found that wine consumption correlated with a significant reduction in the risk for type 2 diabetes compared with no or rare alcohol consumption (pooled relative risks, 0.85), while consumption of beer or spirits was associated with a slight trend toward decreasing risk for type 2 diabetes (relative risk, 0.96 and 0.95, respectively). 

There was a U-shaped correlation between all 3 alcohol types and type 2 diabetes. The peak risk reduction was seen for 20 g to 30 g per day for wine and beer and for 7 g to 15 g per day of spirits, with decreases of 20%, 9%, and 5%, respectively.

"This study indicated that wine may be more helpful for protection against type 2 diabetes than beer or spirits," the researchers wrote.
