Caffeine may help protect brain cells from the damage that causes Parkinson�s, dementia, and Alzheimer�s. And the antioxidants in coffee could help prevent liver disease.
It boosts your brainpower.
Java keeps you juiced when you�re sleep-deprived, but a cup before a test can also sharpen memory and keep you alert.

It keeps you slim.
The caffeine in coffee can speed up metabolism and fat-burning, which helps lower your risk of type 2 diabetes and obesity. And black coffee is one of the lowest-calorie drink choices around.
