Affects of coffee consumption

As with caffeinated coffee, the majority of published studies that have evaluated the relationship between decaffeinated coffee and risk of type 2 diabetes have reported similar inverse associations3,6-8.

  • A 2014 meta-analysis of prospective studies concluded,in addition to an effect with caffeinated coffee, decaffeinated coffee also showed an 11% reduction for every 2 additional cups per day6
  • Two specific studies both published in 2010 - a French study19 and a large US study with African-American women20 – also looked at the association between type 2 diabetes and decaffeinated coffee. While the French study confirmed an association19, the US one did not report a correlation20
  • A multi-ethnic cohort study in 2014, also considered the effects of gender on the caffeine/type 2 diabetes association, suggesting that caffeinated coffee consumption was much more protective against diabetes in women of all ethnic groups than in men (where the effect was present but smaller); but also that this finding did not apply to decaffeinated coffee21
