#368 ‒ The protein debate: optimal intake, limitations of the RDA, whether high-protein intake is harmful, and how to think about processed foods | David Allison, Ph.D. | The Peter Attia Drive

In this episode of The Drive, Peter Attia interviews Dr. David Allison about the contentious topic of protein intake. They discuss the history and limitations of the Recommended Dietary Allowance (RDA) for protein, optimal intake levels for health and performance, and the challenges of conducting high-quality nutrition studies. They address conflicts of interest in nutrition science, the role of data transparency, and the demonization of macronutrients. The conversation explores the complexities of nutrition research, including the use of crossover designs and the limitations of epidemiology. They also delve into the debate around processed and ultra-processed foods, questioning whether they are inherently harmful or simply a convenient villain. Finally, they touch on public health strategies for tackling obesity and the potential role of drugs like GLP-1 agonists.
