The Food Matrix: Rethinking Protein Nutrition | Prof. Nick Burd

Is more protein always better? In this episode of We Do Science, I’m joined by Professor Nick Burd to explore protein nutrition, muscle adaptation and why the amount of protein we eat is only part of the story.

Returning to the podcast after six years, Nick shares insights from his research at the University of Illinois into protein metabolism and the food matrix: how a food’s structure and surrounding nutrients influence the way our bodies respond to it. From eggs and salmon to whey and casein, we examine what we can learn from studying whole foods alongside isolated proteins and supplements.

We discuss the difference between maximal and optimal protein intake, why muscle protein synthesis shouldn’t automatically be equated with muscle growth, and how protein strategies may differ between strength and endurance athletes. We also explore anabolic resistance, muscle quality and the questions researchers are still working to answer.

Whether you’re a sports nutrition practitioner, coach, athlete or student, this conversation offers a closer look at how to interpret protein research and apply it in practice, with a reminder of the central role of consistent exercise in supporting muscle adaptation.
