Keeping the intestinal flora balanced is the best way as the many organisms work in concert to protect the intestinal lining. Soluble fibers found in vegetables feed bacteria in the colon to produce fatty acids that help to prevent leaky gut in the samll intestine. Taking a daily dose of probiotics helps to refortify bacteria that have been found to promote health and overall balance within the intestinal tract.
I recommend that people take a maintenance dosage of the McCombs Plan supplements after they've finished the Plan:
Candida Force - 5 once a day
Detox Essentials - 2 to 4 a day
Flora Prime - 5 once a day
The Candida Force will help to assure that the candida remains in its normal yeast form.
