The cultured food I am talking about here does not contain salt …. cultured butter, creme fraiche, coconut kefir, cultured vegetables; all living foods made with probiotic starter*. NO salt. See more about that bit here.
When you eat unsalted, cultured food, the probiotics in them will go into your gut/inner ecosystem and set up shop where they make babies, grow in population, and essentially build micro-cities the size of New York City in a matter of hours. No joke. Once they settle into your gut lining they are in a position to support you in various beneficial ways.
