How to get health benefits from coffee
Pick dark or medium roast coffee.
Dark roast coffees have higher levels of healthy antioxidants than lighter roast coffees. These antioxidants have been shown to help prevent weight gain and reduce the risk of type 2 diabetes and alzheimer's disease.
Medium roast coffees also have some similar antioxidant qualities and health benefits. There is some evidence that extremely dark roast coffees lose some of their antioxidant health benefits.
