The meta-analyses have suggested that drinking 3-4 cups of coffee per day is associated with an approximate 25% lower risk of developing type 2 diabetes.
Thirty prospective studies, with a total of 1,185,210 participants were analysed by Professor Kjeld Hermansen, who explored the potential mechanistic perspectives behind the inverse association between coffee consumption and type 2 diabetes.
These findings were announced at the European Association for the Study of Diabetes (EASD) 2018 Annual Meeting in Berlin, Germany by the Institute for Scientific Information on Coffee (ISIC)
The researchers considered the different variations and types of coffee drinks consumed around the world. Coffee habits widely, with short espresso style coffees popular in some countries like Italy, whilst longer, more complicated coffee drinks with additions such as milk, syrups and powders are more popular elsewhere.
In-depth research on the many varieties of coffee was not completed, however the association between coffee intake and a reduced risk of type 2 diabetes is most likely to be linked with the coffee itself.
Professor Hermansen mentioned that the Caffeine, Hydroxycinnamic acids, Trigonelline, Diterpenes (e.g. cafestoland and kahweol) and Caffeic acid present in coffee could be potentially clinically relevant.
In addition, they described that “Meta-analyses have suggestedthat both caffeinated and decaffeinated coffee are associated with a reduced risk of type 2 diabetes, a finding also observed by Professor Carlström, suggesting that caffeine itself does not explain the effect.
