17 Jul Sarah Brandow: The Microbiome Revolution—Why Your Gut Controls Your Hormones, Cravings & Long-Term Health
Podcast: Play in new window | Download Subscribe: RSS
What if the key to balancing hormones, improving digestion, reducing inflammation, and even lowering breast cancer risk isn’t another supplement—but the trillions of microbes already living inside you?
In this fascinating conversation, Darin sits down with clinical nutritionist and PhD researcher Sara Brandow to unpack the rapidly emerging science of the gut microbiome and its profound influence on women’s health. From estrogen metabolism and PCOS to the dangers of restrictive diets, social media misinformation, and the hierarchy of scientific evidence, Sara explains why diversity, not dietary perfection—is the true foundation of long-term wellness.
Together they explore why the carnivore diet may starve beneficial gut bacteria, how fear surrounding lectins and detoxes has led many people astray, the importance of feeding your microbiome with fiber-rich whole foods, and why meaningful health transformation happens gradually, not through quick fixes.
If you’ve ever felt overwhelmed by conflicting nutrition advice, this episode offers a science-backed roadmap toward building a healthier, more resilient inner ecosystem.
