OBC Food Rules-Day33: Eat Some Foods that have been Predigested by Bacteria or Fungi

Many traditional cultures swear by the health benefits of fermented foods-foods that have been transformed by live microorganisms, such as yogurt or sauerkraut, soy sauce, kimchi, and sourdough bread.  These foods can be a good source of vitamin B12, an essential nutrient you can't get from plants.  (B12 is produced by animals and bacteria.)  Many fermented foods also contain probiotics-beneficial bacteria that research suggests improve the function of the digestive and immune systems and, according to some studies, help reduce allergic reactions and inflammation.
