Recent scientific evidence has consistently linked regular, moderate coffee consumption with a possible reduced risk of developing type 2 diabetes.
The study outlines the epidemiological evidence linking coffee consumption to diabetes prevention, highlighting that three to four cups of coffee per day is associated with an approximate 25 per cent lower risk of developing type 2 diabetes, compared to none or less than two cups per day.
Another study also found an inverse dose dependent response effect with each additional cup of coffee reducing the relative risk by 7-8 per cent.
The studies suggest an association between moderate coffee consumption and reduced risk of developing diabetes, however, they are unable to infer a causal effect.
A prospective randomised controlled trial, tested glucose and insulin after an oral glucose tolerance test with 12g decaffeinated coffee, 1g chlorogenic acid, 500 mg trigonelline, or placebo.
This study demonstrated that chlorogenic acid, and trigonelline reduced early glucose and insulin responses, and contribute to the putative beneficial effect of coffee.

The study notes that the association between coffee consumption a reduced risk of type 2 diabetes could be seen as counter intuitive, as drinking coffee is often linked to unhealthier habits.
"A dose-dependent inverse association between coffee drinking and total mortality has been demonstrated in general population and it persists among diabetics.
Although more research on the effect of coffee in health is yet needed, current information suggests that coffee is not as bad as previously considered!" Pilar Riobo Servan from Jimenez Diaz-Capio Hospital of Madrid said.
