It has been revealed how many cups of coffee a day can extend your life.

According to Rodrigo Cunha, PhD, co-author of the new review and professor of neurobiology at the University of Coimbra, the antioxidants found in coffee can reduce the chemical damage to cells. They also enable cells to recover more effectively after inflammation.

The benefits of coffee may also be linked to its composition, which includes a mix of over 2000 potentially bioactive compounds. Among these are polyphenols, which help reduce inflammation and regulate insulin production.
