type 2 diabetes

Summary

• Scientific evidence published over the last five years consistently links regular, moderate coffee consumption with a reduced risk of developing type 2 diabetes.
• The association is documented in several different populations and shows a consistent dose response, i.e. lower risk at higher consumption levels:

Drinking 3 to 4 cups of coffee per day is associated with an approximate 25% lower risk of developing type 2 diabetes compared to consuming none or less than 2 cups per day.

Every additional cup of coffee up to 6-8 cups /day (regular or decaffeinated) is associated with a 5-10% lower risk of developing type 2 diabetes.

• The mechanisms underlying this association between moderate coffee consumption and reduced risk of developing type 2 diabetes need further investigation, to confirm the role of individual constituents in particular, such as caffeine and chlorogenic acids.
