For people who want to be healthy, eating  fermented foods is a great option because they provide our digestive  system with healthy gut bacteria. Fermented foods go through the process  of fermentation where the natural bacteria feed on the starch and sugar  in the food hence creating lactic acid. This process preserves the food  and creates beneficial, Omega-3-fatty acids and various strains of  probiotics.
With probiotic supplements, it has been a concern  that there are not enough live bacteria in the capsules to make it  through the stomach and into the rest of the digestive system The fact  is that fermented foods contain a significant amount more good bacteria  and are more likely to make it into our guts. 
When you regularly  eat fermented foods, you really don’t need to take any supplements or  vitamins. Fermented foods contain most of the required maximum nutrients  and probiotic boost the body needs. Because these foods are more  bioavailable, they are more easily assimilated into every cell of your  body. So, start saving money, time and your guts by adding these foods  to your daily diet.
