The use of fermented foods is applicable to most people. Not all, but most. If you are not ready, they aggravate. Thus gas, bloating, etc. You won't be able to monitor the small intestinal pH. Candida can linger, but Phase 3 is also addressing that. Candida can employ biofilms and has many permutations of mutations and innate survival skills. Changing the terrain with this program sets the foundation for having immunological control of candida. That control was one of the immune system’s very first lessons after birth. So try 1 Tbsp. of a fermented food, (i.e. - raw organic sauerkraut, some fermented celery, or a bit of raw organic fermented pickle). If that works, then increase gradually to where you are using a 1 Tbsp. size amount. This will be providing trillions of lactobacilli species to serve as transient, lactic acid-producing, pathogen-herding, probiotic species-colonizing benefits.
