Coffee consumption reduces type-2 diabetes risk: EPIC study

DBR Staff Writer Published 22 February 2012

Drinking four or more cups of coffee a day - either caffeinated or decaffeinated - reduces the risk of either type-2 diabetes, cardiovascular disease (myocardial infarction and stroke in particular), or cancer, according to the European Prospective Investigation into Cancer and Nutrition (EPIC) study.

The EPIC study is a multicenter prospective cohort study in 10 European countries, looking at the associations between diet, lifestyle and chronic disease risk.

The study, conducted on 42,659 German subjects, after nine years of follow up found that those who drank four or more cups of caffeinated coffee a day had a 23% lower risk of developing type-2 diabetes than those who drank less than one cup a day.

Decaffeinated coffee consumption was also inversely associated with type-2 diabetes risk.

Anna Floegel from the German Institute of Human Nutrition Potsdam-Rehbruecke and colleagues, analyzed data for participants recruited between 1994-1998, who completed a food frequency questionnaire to assess, among other things, their habitual consumption of caffeinated and decaffeinated coffee, reported coffeeandhealth.org.

A medical history was also taken. Every 2-3 years thereafter, follow-up questionnaires were completed to identify cases of chronic diseases.

The authors said despite a general belief that coffee may be harmful, the study does not support the hypothesis that coffee is detrimental to human health.

"We found no association between coffee consumption and the overall risk of chronic disease; in fact we observed an inverse association between coffee consumption and type-2 diabetes risk, which challenges the evidence base for current recommendations to moderate our coffee consumption," they said.
