Are We Getting Nutrition Wrong? Insulin Resistance, Supplements & Cholesterol | Dr. Lori Rose

What if everything you've been taught about insulin resistance, antioxidant supplements, and cholesterol isn't the whole story? Is cutting carbs really the best way to improve insulin sensitivity? Can taking too many antioxidants backfire? And are we overlooking the role of gut health, nutrient deficiencies, and chronic stress when making nutrition recommendations? In this episode of the Health Detective Podcast, host Michele Scarlet sits down with Dr. Lori Rose, PhD biologist, Functional Diagnostic Nutrition Practitioner (FDN-P), registered herbalist, and college professor, to challenge some of the most persistent nutrition myths in conventional and functional health. From mitochondrial health and insulin resistance to the debate surrounding cholesterol, statins, and dietary fat, Dr. Lori shares her perspective on why nutrition is far more complicated than simply cutting carbs, counting calories, or adding another supplement. If you're a functional health practitioner, nutrition coach, health professional, or someone who wants to understand the science behind food and supplements, this conversation will give you plenty to think about. 🔬 5 LABS IN 5 DAYS STARTS MONDAY, OCTOBER 19!
