Dr Oz: How Much Can Probiotics Help Your Gut?
Probiotics are part of a $24 billion industry but just how effective are they? Can probiotic foods really improve your digestion in just two weeks? Dr Oz conducted an experiment where he asked volunteers to eat one cup of probiotic food like yogurt and four cups of prebiotic foods like leafy greens. Then, they sent in stool samples to a lab where they were tested and analyzed. The volunteers kept a food diary and a symptom diary to keep track of what they ate and how they felt.
