Misinformation in nutrition is rampant. From demonizing red meat to hyping plant-based diets, conflicting advice has left many people confused about what’s truly evidence-based. In this episode, I am joined by Dr. Bradley Johnston, an expert in evidence-based nutrition and public health policies, to separate fact from fiction. With nearly 200 peer-reviewed publications, Dr. Johnston has challenged conventional wisdom—including recommendations from major organizations like the World Health Organization. He shares how evidence-based practices should guide our dietary choices, the importance of systematic reviews and meta-analyses, and how cognitive biases influence the research we trust.
Key Points:
If you’ve ever questioned dietary guidelines, nutrition headlines, or conflicting health advice, this episode is a must-listen. Get ready to rethink everything you thought you knew about nutrition.
