Despite longstanding calls for scientific consensus on the definitions and categorisation of animal-restrictive dietary groups (Ruby, 2012; Rosenfeld, 2018), significant discrepancies remain. Urgency to address this issue is only growing, as dietary diversity increases. Without a shared conceptual and methodological framework, the field risks hindering theoretical integration and meta-analytic work. In this commentary, we highlight two key considerations in dietary group categorisation, calling for greater clarity, consistency and collaboration to strengthen cumulative progress in the field.
