Green coffee is a seed from un roasted coffee fruit like ordinary coffee. But it is processed in a certain way so that it can release the content of chlorogenic acid (cholorgenic acid) which is believed to have many health benefits. "Chlorogenic acid in green coffee acts as an antioxidant. This substance will control blood pressure, help slimming and maintain blood sugar levels in the body," said Dr. Simran Saini from Fortis Hospital, as quoted from the site food.ndtv.com.
