What is Green Coffee Bean?
Green coffee beans are no different from a typical coffee bean except for the fact that they are left unroasted, thus keeping them green.  This is because the roasting of coffee beans results in the loss of chlorogenic acid.  Because the unroasted green coffee beans are filled with chlorogenic acid, antioxidants and other anti-inflammatory substances are abundant within the green coffee bean. Of course, green coffee beans also contain caffeine which can improve brain function and alertness.
What are the Health Benefits of Green Coffee Bean?
The major health benefits of green coffee beans primarily come from chlorogenic acid. The antioxidants that are present in chlorogenic acid all boost your overall health and immune system.  In addition, the daily consumption of green coffee bean extract over even a couple weeks can lower blood pressure and even regulate sugars in the blood which can be used to treat and even help prevent type 2 diabetes.  In 2012, green coffee bean extract was endorsed by celebrity physician, Dr. Oz, who said that it can be used as a miracle weight loss supplement.  Researchers argue that the polyphenol antioxidants combined with the caffeine which exists within green coffee beans promote weight loss by reducing the absorption of fat and glucose in the stomach.
