Trend Longevity Rating
real progress in parts; other parts stalled or got overtaken
How this trend held up
Part of this trend fully arrived: calorie and nutrition labeling on restaurant menus is now standard and legally required across major U.S. chains, and food-scanning apps (Yuka and similar tools succeeded Fooducate as category leaders) are mainstream. But the app-driven, real-time "augmented nutrition" vision — where a smartphone becomes the primary tool people use to control what they eat — was largely overtaken by a development the book couldn't have anticipated: GLP-1 weight-loss drugs like Ozempic and Wegovy, which reshaped the cultural conversation about food control far more than any nutrition app did. The knowledge-and-control instinct behind this trend was right; the delivery mechanism the book bet on was not the one that ended up mattering most.
