Summary
Plant-based nutrition has rarely been more contested. Seed oils are vilified, butter is celebrated, protein is treated as a pure quantity question, and nutrition epidemiology is routinely dismissed by people who have never read one of its papers. In this episode, I sit down with Dr Andrea Glenn, an Assistant Professor at NYU and Visiting Scientist at the Harvard T.H. Chan School of Public Health, to look at what the strongest evidence actually shows. We cover the recent plant-versus-animal protein data from the Nurses' Health Studies and Health Professionals Follow-up Study, the Portfolio Diet, the new CHEAP trial, the JAMA Internal Medicine butter and plant oil paper, and the new 2026 AHA dietary guidance. What we cover: The plant-to-animal protein ratio and its association with cardiovascular and coronary heart disease risk The Portfolio Diet, what it contains, and how its LDL-lowering effects compare to a low-dose statin Butter, beef tallow, tropical oils, and what the latest mortality data show Why "low-carb" is not one diet, and why food sources matter as much as the macronutrient breakdown A grounded defence of nutrition epidemiology and the role of food frequency questionnaires Practical takeaways for how to eat in line with the new AHA guidance This is the conversation I wanted to have for anyone tired of nutrition by hashtag. If it lands, a quick rating or review on Apple Podcasts or Spotify makes a real difference.
