It has been documented over and over again that coffee has many amazing benefits for the human body especially the brain. Here are five interesting facts about how coffee can be great for your body.

Chlorogenic Acid — Chlorogenic acid is a natural compound found in coffee beans that helps to reduce the risk of diseases such as diabetes and cancer. Another way chlorogenic acid affects the body is that it helps to reduce blood pressure and weight loss and in some studies, it has shown to reduce blood sugar levels.

Magnesium — each cup of coffee contains about 7 mg of magnesium. Because Americans do not eat enough fruits and vegetables we do not take in enough magnesium for our bodies. This is where coffee comes to help us with our magnesium intake.

Potassium — now each cup of coffee does contain about 116 mg of potassium. Our body needs about 4700 mg of potassium every day. So coffee does not give us enough potassium but it does help to fill in the need and get us closer to our mark of what we need.

Caffeine — caffeine itself is an antioxidant. Caffeine can help cure headaches help with losing weight and help with preventing diabetes.

Overall coffee has more antioxidants then both green and black teas and red wine, Coffee is the world's largest source of antioxidants.
