Mounting evidence suggests that coffee drinkers have a lower risk of developing Type 2 diabetes, gallstones, Parkinson's disease, cirrhosis and certain types of cancers.

Hundreds of compounds, including antioxidants, seem to be responsible for coffee's many protective benefits. A Harvard study revealed coffee drinkers had a lower risk of dying of cardiovascular causes than nondrinkers.  A Norwegian study found that a typical serving of brewed coffee is richer in antioxidants than a serving of blueberries, raspberries, or many fruit juices.

Brain bonus: Coffee might help the mind as much as the body. One study found that sleep-deprived rats were much calmer simply after inhaling the scent of roasted coffee beans.

Sipping tips: Still, many dietitians recommend drinking in moderation – only one or two cups of coffee a day and without the added whole milk and sugar (which jolt only the waistline). If you drink much more than that, the caffeine can dehydrate you or raise your blood pressure. Pregnant women should limit their intake as well, since coffee can boost the risk of miscarriage.
