1: Coffee helps fight disease.
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.
2: 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.
If it makes you too jittery, mix regular with decaf, or drink it with breakfast. Just avoid caffeine for at least four hours before bedtime.
3: 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.
