Highly Processed Foods Explained: What They Are and Why They Matter

In this episode, Dr. Chris Taylor joins us to unpack the growing conversation around processed and ultra-processed foods, and why these labels often oversimplify a much more complex food system. From common claims about additives, preservatives, and metabolic health, Dr. Taylor explains what food processing really means and where the evidence still falls short. We explore how nutrient density, fiber, energy density, and substitution effects influence how much we eat, why blanket recommendations can lead to unintended consequences, and how reformulation has historically changed the nutritional profile of foods. The conversation also dives into food access, shelf life, and the role processed foods play in feeding a diverse population, especially when fresh food is not always accessible or affordable. Finally, Dr. Taylor challenges to good vs. bad food narrative, encouraging listeners to think more intentionally about overall dietary patterns, nutrient tradeoffs, and making informed choices rather than reacting to headlines about ultra-processed foods.

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. Designed to inform and engage both professionals and curious consumers, we highlight the stories behind the science to build deeper connections to food and agriculture research. The Science That Feeds Us is supported by NC State Extension and NC State University.
