If you're looking for an easy way to cut your risk of diabetes and Parkinson's, there's new evidence that coffee may be the answer.

According to a new study at Harvard University, people who drink two to three cups of coffee a day have a lower risk of developing those diseases.

Doctors say coffee is loaded with antioxidants, which can prevent damage to your cells.

But the study also warns that drinking too much coffee can lead to rapid heart beat and high blood pressure.

That's why moderation is key.
