    Why Protein Matters: Science, Nutrition, and the Latest Wellness Craze

    In this episode, we sit down with Dr. Eric Trexler to unpack why protein has exploded from a niche fitness topic into a full-blown wellness trend, and what the science actually says behind the hype. From the rise of resistance training to misconceptions about protein needs, Dr. Trexler explains how protein works in the body, why lifters need it differently than sedentary consumers, and how muscle growth really happens. We explore plant versus animal protein sources, concerns around saturated fat, and why high protein products are not always as helpful as they seem. The conversation also dives into how protein is being marketed, especially to women, the pitfalls of trendy supplements like collagen, and why resistance training matters far more than chasing protein numbers alone. Plus, Dr. Trexler shares practical, realistic advice for balancing protein for performance, long-term health, and the simple enjoyment of food, along with encouragement for anyone curious about getting started with resistance training.  Learn more about Dr. Trexler’s work below: Duke University Bio Page: https://scholars.duke.edu/person/eric.trexler  Iron Culture Podcast: https://ironculture.libsyn.com/  Mass Research Review: https://massresearchreview.com/  Check out the following resources to learn more about today’s topic: Article: Systematic review and meta-analysis of protein intake to support muscle mass and function in healthy adults: https://pmc.ncbi.nlm.nih.gov/articles/PMC8978023/  Article: The skeletal muscle anabolic response to plant- versus animal-based protein consumption: https://pubmed.ncbi.nlm.nih.gov/26224750/  Article: High-protein plant-based diet versus a protein-matched omnivorous diet to support resistance training adaptations: A comparison between habitual vegans and omnivores: https://pubmed.ncbi.nlm.nih.gov/33599941/  Article: Whey protein supplementation is superior to leucine-matched collagen peptides to increase muscle thickness during a 10-week resistance training program in untrained young adults: https://pubmed.ncbi.nlm.nih.gov/35042187/  Article: The effects of creatine supplementation combined with resistance training on regional measures of muscle hypertrophy: A systematic review with meta-analysis: https://pmc.ncbi.nlm.nih.gov/articles/PMC10180745/  The Science That Feeds Us podcast brings together extension agents, faculty specialists, and scientists for interdisciplinary conversations on emerging trends in agriculture and the food system.
