Alcohol consumption and the risk of Type 2 Diabetes
22nd January 2006
Moderate alcohol consumption has been proven to be beneficial in cutting down the risk for many conditions and most importantly heart disease. So, what is the relationship between alcohol consumption and the risk of type 2 diabetes? A number of prospective epidemiological studies have shown that moderate alcohol consumption has an inverse association with the risk of developing type 2 diabetes. To be more precise moderate alcohol consumption appears to reduce the risk of developing type 2 diabetes by about 30%(Diabetes Care. 2005 Mar;28(3):719-25). The most recent published study, was conducted in the Netherlands (Diabetes Care. 2005 Dec;28(12):2933-8) in a sample of 16,330 women aged 49-70 years old. The researchers concluded that moderate alcohol consumption, significantly decreases the risk of type 2 diabetes. The type of alcohol doesn’t however appear to play a significant role.
Diabetics, should be careful with alcohol consumption because it may increase the risk of hypoglycemia. Also, it has been shown to lead to suboptimal preventive practices like not performing daily glucose tests (Fam Med. 2005 Sep;37(8):589-94.). Nonetheless, moderate alcohol consumption can decrease the risk of cardiovascular disease. So as always moderation is the key.
