From practices to outcomes: a perspective on regenerative agriculture, nutrient density, and the need for results-based verification in U.S. food systems

Abstract

Regenerative agriculture has emerged as a promising framework for improving the sustainability of food systems. Interest is also growing in its potential to enhance food nutrient density. Mechanistic links between agricultural practices, soil health, and food composition are biologically plausible and supported by emerging evidence. However, substantial variability in nutrient composition across production systems, combined with methodological limitations in current research, has hindered consistent conclusions. Concurrently, regenerative and grass-fed and finished certification programs in the United States have expanded rapidly, standardizing production practices and, in some cases, incorporating environmental indicators such as soil health and biodiversity. Yet these frameworks rely primarily on the verification of practices (obligations of means) rather than the measurement of outcomes (obligations of results), particularly at the level of food composition. Despite this, nutrition-related claims, both explicit and implicit, are increasingly associated with these systems, while routine measurement of nutrient density remains absent. This perspective examines the intersection of regenerative agriculture, nutrient density, and certification systems, highlighting a structural gap between production practices, communicated claims, and measurable outcomes, and proposes a shift toward integrating obligations of results, including standardized nutrient profiling and improved data transparency, alongside existing practice-based standards. Drawing on examples such as the Bleu-Blanc-Coeur initiative, we argue that hybrid frameworks combining practices with outcome-based verification are feasible and could strengthen the scientific basis of regenerative agriculture, support more rigorous evaluation of food quality, and improve transparency and trust within the food system.
