Researcher Mark A. Pereira and his team discovered that women who drink more than six cups of coffee each day are more likely to develop a type two diabetes. Type Two diabetes, as we all know, occurs in middle age. But in the researches made by Pereira and company, it is found out that antioxidant is the anti-reducing element in coffee that prevents type two diabetes and not caffeine. Accordingly, it's better to drink decaf as it reduces the chances of getting type two diabetes. In the statistics, twenty-percent diabetes reduction can only be reduced when you drink coffee. On the other hand, thirty-three percent can be reduced if it's decaf. Incidentally., antioxidants protect the beta cells of pancreas from damages.
