#558: Rethinking Ultra-Processed Foods in the Modern Food System – Duane Mellor, PhD

Sigma Nutrition Radio

Discussions around ultra-processed foods (UPFs) and their role in public health have gained significant traction in recent years. While some advocate for categorizing and regulating these foods due to their potential negative health effects, others argue that such classifications can oversimplify the issue and detract from more actionable dietary changes.

In this episode, Dr. Duane Mellor, a registered dietitian and researcher, joins us to explore the complexities of the UPF debate. Rather than dismissing the concept outright, Dr. Mellor emphasizes the importance of nuanced discussion, bridging the gap between research findings and practical, evidence-based dietary guidance.

Throughout this conversation, we unpack the broader implications of ultra-processed foods in the food system, consider how added fat, salt, and sugar contribute to public health challenges, and explore realistic approaches for dietary improvements.
