Summary
This invited opinion paper by Provenza and Gregorini (2018) presents a critical analysis of how modern food systems constrain meaningful dietary choice for herbivores and, by extension, human consumers. Drawing on behavioural ecology and grazing science, the authors argue that standardised, low-diversity feeding regimens—whether for livestock or in human nutrition—undermine both animal welfare and nutritional adequacy. The paper challenges food system design practices that limit choice, proposing that dietary diversity and autonomous selection are essential to health outcomes for both species.
UK applicability
The argument regarding pasture-based systems and animal choice is directly applicable to UK livestock farming policy and practice, particularly in contexts of grassland management and organic/regenerative farming advocacy. The broader critique of standardised food systems may inform UK food policy discussions around dietary diversity and nutrition, though the paper's focus on grazing herbivores may require contextualisation to UK arable and mixed farming systems.
Key measures
As suggested by the title and journal context, the paper likely discusses dietary diversity metrics, animal feeding behaviour, nutritional diversity, and choice architecture within food systems, though specific quantitative measures are not established from the metadata alone.
Outcomes reported
The paper critiques structural constraints within contemporary food systems that limit dietary diversity and meaningful choice for both grazing herbivores and human consumers. The authors examine how standardised feeding regimens undermine animal agency and, by extension, nutritional outcomes for both animals and humans.
