In this episode, we sit down with Dr. Carrie Pickworth to break down one of the most talked-about and often misunderstood topics in food and agriculture: beef production. From grass-fed to grain-fed systems, Dr. Pickworth explains what these production terms actually mean and how beef cattle are raised across different stages of their lives. We explore how cattle diets influence growth, efficiency, and meat quality, what science says about the nutritional differences between grass-finished and grain-finished beef, and why those differences matter far less for human health than many headlines suggest. The conversation also addresses common concerns around hormones and antibiotics, including how they are used, what safeguards are in place, and why context is critical when interpreting risk. Finally, Dr. Pickworth discusses the role of cattle as upcyclers in a sustainable food system, the use of byproducts that would otherwise go to waste, and what excites her most about the future of beef research and production.
