It may be the organ you thought you didn't need, but Dr. Oz reveals why the spleen is vital to your immunity.

Tips to keep your spleen healthy:

  1. If you have pain in your upper left quadrant (where the spleen is located) have it checked out.
  2. Wear a seat belt to prevent splenic injuries during car accidents.
  3. Eat dark chocolate. The flavonoids boost the immune system and help the spleen respond to infections in your body.
  4. Include foods rich in vitamin B6, like potatoes to keep your spleen and immune system healthy.
