According to researchers at UCLA coffee increases plasma levels of a protein called SHBG which regulates the levels of the sex hormones testosterone and estrogen which in turn have a role in development of type 2 diabetes.
Moderate consumption of coffee can help stave the diabetes risk although earlier there were some researches which were ambiguous about its effect on other diseases like cancer.
According to a study conducted by the European Prospective Investigation into Cancer and Nutrition (EPIC),Germany on 42,659 people for almost a decade showed coffee helps prevent diabetes. Ten countries contribute to the EPIC study, including two centres in Germany which carried out the latest analysis. Drinking more than four cups of coffee a day — caffeinated and decaffeinated — compared with less than one cup was not linked to a higher risk of developing a chronic disease, the findings revealed.
Euan Paul of British Coffee Association said: “This study adds to the growing scientific data that suggests moderate coffee consumption, four to five cups of coffee per day, is safe and does not increase risk of chronic diseases.”
