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!
