New research has suggested that drinking three to four cups of coffee each day could lower the risk of type 2 diabetes by 25 per cent.
The Institute for Scientific Information on Coffee in Switzerland revealed these findings in their annual diabetes report just in time to mark World Diabetes Day, on November 14.
For every additional cup of coffee, you could earn another seven to eight per cent reduced risk, with the benefits also dependent on how the coffee was made.
Effects on diabetes
Filtered coffee possesses a greater proactive effect than boiled coffee, but researchers are still uncertain as to which mechanisms work inside the coffee that lowers the risk of type 2 diabetes.
Research has shown the effect of caffeine is minimal, with decaffeinated coffee exhibiting an enhanced proactive effect than caffeinated coffee.
It has been suggested the possibilities for this reduced risk could be that coffee improves glucose tolerance, energy metabolism and burns more calories.
The report added: “Coffee could affect insulin sensitivity in the body. A 2014 study of Japanese men suggested higher coffee consumption may be protected against insulin resistance in normal weight individuals.
“Another possibility is it could simply be an effect of calorie displacement, where choosing coffee over a sugary drink leads to a reduction in calorie consumption”.
