Podcast Highlights

In this episode of the Rational Wellness Podcast, host Dr. Ben Weitz interviews Dr. Tom Fabian, an expert in microbiome science and a clinical education specialist at Diagnostic Solutions Lab. They discuss the new Stool Omics test—an advanced quantitative analysis of bile acids and short-chain fatty acids used in conjunction with the GI Map stool test. The discussion covers the clinical need for this test, the differences between commensals, opportunists, and pathogens, and how bile acids and fiber can impact gut health, motility, and inflammation. The episode also touches on dietary interventions, including fiber and polyphenols, and highlights the complexities of treating conditions like IBS and inflammatory bowel disease.
