Sauerkraut aids digestion
Probiotic bacteria, used as a natural preservative during Sauerkraut fermentation, create lactic acid. Lactic acid, in turn, helps aid in digestion by restoring a healthy balance of good bacteria in the digestive system.  Cleansing the digestive tract of harmful bacteria can also provide relief from the symptoms of Irritable Bowel Syndrome (IBS).

A diet that regularly includes fermented foods can also help prevent colon cancer and enhance immune function.
