281. The Facts on Lead in Protein Powder, 22 Hot Topics in Endurance Sports, Weird Science of MRI Findings, and Increasing Carbs!

We loved recording this episode! The main topic was the article that rocked the athletic world last week, which asserted that many protein powders had unsafe amounts of lead contamination. We broke down the numbers to reach a much more nuanced conclusion that should help you feel better about it all. And that led to a broader discussion on the perils of advocacy being presented as science. We also talked about a shocking study on 45 asymptomatic people, which found labrum defects in 69% of hips! MRIs are complicated, unveiling mysteries of the human body and the strange line between structural and inflammatory issues. We discuss what it all means! And this one was full of great topics! Other topics: recovery cake, Megan’s beastly bike workout, our attempt to program AI with 22 sexy concepts in athletics, a study on actual v. planned carb intake in races, Courtney Dauwalter doing another marathon, a hypothetical about Cole Hocker in ultras, breaking up moderate running with sub-threshold intervals, how grief impacts training, energy deficits in multi-day events, preparing for heat, period parties, and when to FAFO. We love you all! HUZZAH!
