Episode 50: Debunking Wellness Myths and Supplement Hype With Registered Dietitian Kevin Klatt, PhD
Episode 50
Friday, 30 October, 2026
Do you need to balance your hormones? Is collagen worth buying? And can years of dieting really damage your metabolism? In this episode of Discovering Nutrition, Eliisa sits down with registered dietitian and nutrition researcher Kevin Klatt, PhD, RD, an assistant professor at the University of Toronto, to unpack the nutrition and wellness claims filling our social feeds. Kevin explains how he evaluates evidence, why a convincing biological explanation doesn’t establish that a treatment works, and why uncertainty belongs in honest health advice. He also shares his perspective as a researcher and someone navigating an autoimmune condition. Together, they discuss hormone balancing, perimenopause, protein and fibermaxxing, diet soda, collagen supplements, gut-healing claims, food-sensitivity tests, metabolic adaptation, and anti-inflammatory diets. They also explore MTHFR and prenatal vitamin claims, pregnancy nutrition anxiety, food guilt, and the role of nutrition tracking. Whether you’re choosing supplements, making sense of conflicting advice, or trying to feel more at ease with your food choices, this episode offers a candid and funny conversation about what we know, what we’re still learning, and how to keep wellness promises in perspective.
