It is a well-known fact that antioxidants play a key role in enhancing the overall body metabolism leading to weight loss. Antioxidants help prevent the oxidation of other food molecules inhibiting the formation of free radicals in the system. It has been discovered that untreated or raw green coffee beans contain very high levels of chlorogenic acid, which is rich in antioxidants. This acid is excellent for enhancing overall health of the body. It has also been observed that antioxidants help in the prevention of life threatening diseases such as cancer, coronary heart disease, and even altitude sicknesses and many more.
