All these years we have only heard experts asking us to limit those countless cups of coffee that keeps us alert during long working hours. But researchers from China and The University of California, Los Angeles (UCLA), suggest that people who consume more than four cups of coffee a day are at lower risk of getting diabetes. There are two different explanations for the same.
Caffeine, caffeic acid, and chlorogenic acid are components present in coffee beans that are known to inhibit the formation of a toxic protein called HIAPP that can cause Type II Diabetes. Caffeic acid and chlorogenic acid are especially effective in this function as compared to caffeine, and therefore, decaffeinated coffee may be a good option!
SHBG (sex hormone-binding globulin), a protein also present in coffee beans is known to offer protection against developing diabetes. Thus coffee consumption can help reduce the risk of diabetes. Scientists also believe that polyphenols present in coffee beans can act as antioxidants which are otherwise known to reduce the risk of diabetes.
To simplify, coffee isn't as bad as it is projected to be. But, here is the "conditions apply" tag: Excessive consumption of any good food can have contraindications, and so is it with coffee!
In the long run, exercising regularly, reducing your body weight if you are overweight, eating right, and limiting the cups of coffee you drink will help you stay longer, healthier, and happier.
