Food Safety Gets Complicated: GRAS, Ultra-Processed Foods & the Science
In this episode of Rooted & Restless, Marianne Smith Edge talks with registered dietitian and food scientist Joy Dubost, PhD, RD about the science and regulations behind some of today’s biggest food and nutrition debates. They take a closer look at the current GRAS (Generally Recognized as Safe) process, what the proposed changes could mean for food safety and transparency, and the ongoing debate over how we define ultra-processed foods. They also explore the push to replace artificial food colors with natural alternatives—and why “natural” doesn't automatically mean safer or better. Along the way, Joy and Marianne unpack how food science, regulation, and nutrition misinformation can get lost in the headlines, leaving consumers wondering what they can trust. What We Cover • An overview of the current GRAS process and how the new proposed rule could impact transparency • Why replacing artificial colors with natural colors isn't as simple as it sounds • Why defining ultra-processed foods is more complicated than it may seem • How consumers can navigate nutrition misinformation and make informed food choices The takeaway? Food and nutrition are rarely as simple as a headline suggests. Understanding the science, looking at the bigger picture, and relying on credible sources, like registered dietitians can help consumers make informed choices without getting caught up in fear or confusion. NOTE: The comment period for the GRAS proposed changes has been extended to a 120- day time period rather than the 90-day period mentioned in the episode.
