Dark chocolate containing 80 percent cacao or higher is packed with nutrients that can strengthen your body’s defense systems and positively affect your overall health.

With the help of over 750,000 stem cells, your body regenerates itself each and every day, states Dr. William Li.

Dark chocolate can mobilize your stem cells to carry out their job to the fullest. At the University of California, San Francisco, researchers found that participants who received a chocolate drink made with cocoa twice a day for thirty days had twice as many stem cells in their circulation as their control group.
