Protein Quality - The Arnold

Iron Radio: Protein Labeling, Plant Proteins, and Arnold Classic Highlights

On Iron Radio, hosts Coach Phil Stevens, Dr. Mike T. Nelson, and Dr. Lonnie Lowery discuss a recent Food and Nutrition Policy (Feb 2026) proposal to eliminate in vivo protein digestibility requirements (PDCAAS) for protein content claims in North America, arguing it would favor plant proteins and could mislead consumers by focusing on grams per serving rather than usable amino acids. They debate implications for athletes, older adults, and the general public, raise concerns about industry-driven label changes, and note how protein blends and undisclosed ratios could be used for profit. The episode also includes show updates (new distribution via the Iron Radio Nutrition Radio Network, newsletter and book mentions) and a brief recap of Arnold event results, prize money disparities, expo changes over time, and how strongman deadlift numbers have escalated.
