In this episode of Rooted & Restless, Marianne Smith Edge is joined by registered dietitian and food trend expert Mindy Hermann, MBA, RDN to unpack how food trends are identified, amplified, and interpreted — and what they really mean for consumers, industry, and health.

The conversation explores where food trends come from, including the role of retailers like Whole Foods and industry intelligence firms such as Datassential and Innova Market Insights.

Mindy explains how trends are predicted and promoted across retail and foodservice, while Marianne mentioned the continued focus on protein and the resurgence of legumes, even in traditionally meat-centric restaurants.

Marianne and Mindy also discuss how food trends move globally, often starting in one region and spreading elsewhere. A key example is the growing influence of GLP-1 medications, which are already shaping food choices in the U.S, with users seeking smaller portions, higher-protein foods, and healthier snack options with their potential ripple effect internationally as these medications expand.

While trends often begin with a small segment of consumers, their broader impact can look very different when viewed through a wider lens. The episode takes a thoughtful look at the socioeconomic implications of food trends, questioning who benefits and who may be left out. Topics like affordability, value, and food insecurity highlight the tension between trend-driven foods and everyday eating realities.

Sustainability and global economics also take center stage as Marianne and Mindy examine trends such as sea vegetables, ancient grains, and so-called “superfoods.” They discuss the environmental potential of sea vegetables as alternative omega-3 sources, the challenges of scaling ancient grains, and the unintended consequences of global demand for foods like quinoa. Marianne shares firsthand observations from Peru, where quinoa’s popularity has increased the local prices and ultimately the its access to the local population.

The episode concludes with an analysis of the future of plant-based meat alternatives, where Mindy explains why consumer interest has cooled and what may come next — including mycoproteins and a renewed focus on dairy and animal proteins. Together, they emphasize that while trends influence curiosity and trial, long-term eating habits are shaped by culture, access, preference, and common-sense nutrition.

Key takeaway: Food trends may grab attention, but understanding their origins, impacts, and limitations helps us make more informed and realistic choices.
