Caffeinated Coffee Protects Against Type 2 Diabetes and Researchers Say They Think They Know Why

Researchers at UCLA say that there is an inverse relationship between the amount of caffeinated coffee a person drinks and his or her risk of developing type 2 diabetes. (The more coffee the less risk.) They say they think this is because caffeinated coffee increases the level of a protein called SHBG in the blood. SHBG regulates the biological activity of the sex hormones testosterone and estrogen and these have long been suspected of playing a role in the development of type 2 diabetes. Tests on women showed that those who drank 4 cups of caffeinated coffee a day had a 56% less chance of developing type 2 diabetes than those who drank none. Decaffeinated coffee does not increase SHBG and does not demonstrate the same protective effect.

Per the article:


The findings have been published in the current edition of the journal, Diabetes.
