  • Science-based nutrition to prevent a heart attack | Michelle Routhenstein, MS, RD

    Science-based nutrition to prevent a heart attack | Michelle Routhenstein, MS, RD
    Dec 22 2025
    In this episode, I’m joined by cardiac dietitian Michelle Routhenstein to unpack why heart disease prevention is still so misunderstood. We explore cholesterol confusion, blood pressure, saturated fat, carbs, supplements, and why personalised nutrition matters far more than rigid dietary rules. Michelle explains how food choices influence plaque progression, inflammation, gut health, and heart rhythm, and why sustainable habits, not extremes, are key for long-term cardiovascular health. What We Cover Why heart disease is still largely preventable yet so common Cholesterol, ApoB, and the biggest nutrition myths patients face Blood pressure as the most powerful but ignored risk factor Soluble fibre, unsaturated fats, and gut health for heart protection Menopause, metabolic changes, and shifting cardiovascular risk Supplements vs food, and when medication still matters A practical, evidence-based conversation on how to protect your heart for the long term.

  • How to build a healthy gut using the latest microbiome science | Dr Suzanne Devkota

    How to build a healthy gut using the latest microbiome science | Dr Suzanne Devkota
    Dec 15 2025
    In this episode I sit down again with microbiome researcher Dr Suzanne Devkota to explore what a healthy microbiome really is and how we can support it. We unpack diversity, early life programming, fibre and microbiota accessible carbohydrates (MACs), plus the genuine role of probiotics, prebiotics and postbiotics. Suzanne also shares cutting edge research on short chain fatty acids, Akkermansia, inflammatory bowel disease, visceral fat and colon cancer, and helps separate solid science from the noise you see online. What We Cover What the microbiome is and how it differs along the digestive tract Why diversity is a key marker of gut health and how chronic disease and diet affect it Early life influences on the microbiome, from birth mode to first foods The realities of stool testing, different methods, and how to interpret results with care Probiotics versus prebiotics versus postbiotics, when each may or may not be useful MAC rich foods, short chain fatty acids and why butyrate is so important for gut barrier integrity The Akkermansia story, mucus, leaky gut and why focusing on one bug is misleading New data on IBD, gut leakiness, bacteria in fat tissue and links to fibrosis and metabolism I hope this conversation gives you a clearer, more grounded view of gut health and helps you focus on practical, sustainable steps that genuinely support your microbiome. You can learn more from Dr Suzanne Devkota by following her on Instagram, or by visiting the Cedars-Sinai Human Microbiome Research Institute and the Devkota Lab. Intro (00:00:00) The Microbiome Conversation (00:01:16) How Diversity Shapes Your Gut’s Health and Resilience (00:04:40) The First Three Years That Shape a Lifetime (00:08:09) What Microbiome Tests Can and Can’t Tell You (00:11:05) Probiotics, Prebiotics, Postbiotics (00:18:05) The Quiet Power of Short-Chain Fatty Acids (00:34:47) The Fiber Controversy and What People Get Wrong (00:47:58) How Daily Habits Quietly Reshape Your Microbiome (00:49:28) Antibiotics, Resetting, and Rebuilding Your Gut (00:52:07) How Early-Life Factors Imprint Your Gut for Decades (00:56:57) Why Chronic Inflammation and IBD Connect Back to the Microbiome (01:03:14) What We’re Learning About Colon Cancer and the Gut (01:16:13) The Future of Microbiome Science and Personalized Gut Care (01:27:45) This episode is brought to you by: 38TERA Consider 38TERA's DMN prebiotic supplement a daily multivitamin for your gut.
