In this episode of the Mikkipedia podcast with Mikki Williden, PhD, we tackle one of the most debated topics in nutrition right now: protein. I help to unpack why protein has become such a focal point, how to interpret the current evidence, and what outcomes actually matter when we’re talking about intake and health. Further, we discuss the long-standing protein RDA and what it was designed to represent.
The discussion then moves into protein quality, addressing common claims around plant versus animal protein, and why mechanistic research doesn’t always align with long-term health outcomes. I also provide some important context around dietary patterns and chronic disease risk, helping to separate the role of protein itself from the broader way people eat.
We finish with a dive into choline, covering its role in the body, how it interacts with other nutrients like folate and betaine, and what this means for people following predominantly plant-based diets.
It’s a thoughtful, nuanced conversation that cuts through the noise and brings clarity to some of the biggest questions in modern nutrition.
