Drink green tea or coffee may protect overweight men and women at high risk of type 2 diabetes called “bold”. This was demonstrated by a team of Japanese researchers in a study that has been published in the Annals of Internal Medicine.
Researchers at Osaka University were followed over a period of five years, 17,413 men and women aged 40-65 years without diabetes at baseline. After 5 years, 231 men and 213 women developed diabetes.
The results show that people who regularly drink at least six cups of green tea a day were 33% less risk of developing type 2 diabetes compared to those who do not. Proponents of coffee, with at least 3 cups a day, have them 42% less risk of developing diabetes compared to those who do not. The effect is more pronounced among overweight men and women.
It seems that black tea or oolong tea, which, unlike the green tea leaves from fermented before being dried, do not protect from diabetes.
The results of this study echo those that have been obtained in Europe and the United States. Studies have now shown that people drinking at least seven cups of coffee a day were 29-52% less risk of developing type 2 diabetes than those who drank less or not at all.
The authors suggest that the protective effect of green tea and coffee is due to the caffeine, which are actually a single molecule. Further studies are still needed to confirm this.
