Type 2 diabetes


A number of studies investigating the possible associations between coffee consumption and reduced risk of developing type 2 diabetes show favourable results with a moderate intake of both caffeinated and decaffeinated coffee

Effects of coffee consumption
  • Scientific research indicates that moderate coffee consumption* is associated with a statistically significant reduced risk of developing type 2 diabetes2-4
  • The association has been studied in a number of different populations and the wealth of evidence suggests that a moderate intake of caffeinated and decaffeinated coffee is associated with a lower risk of developing type 2 diabetes3,4,6-9
  • Currently, a plausible explanation for this association is still lacking. There is no clear consensus on a potential mechanism, although some research suggests coffee components including chlorogenic acids and trigonelline may be key10-12
  • Observations of beneficial effects of coffee consumption on some markers of subclinical inflammation are also interesting13,14
  • The association between coffee/caffeine consumption and diabetes appears to be specific to type 2 diabetes only
*A moderate coffee consumption is typically defined as 3-5 cups per day, based on the European Food Safety Authority’s Scientific opinion on the safety of caffeine5.
