Dietitians as System Builders: Advancing Equity, Sustainability and Health in Community Nutrition and Primary Care

Year: 2026

Type: article

Abstract: Diet-related challenges in primary care and community settings increasingly reflect the convergence of health, social and environmental pressures. Although dietitians routinely navigate this complexity, their system-level contributions often remain implicit. This paper proposes a conceptual framework that positions dietitians as system builders and synthesises insights from systems science, health promotion and ecological models to articulate this role. Three interconnected roles illustrate how dietitians influence system behaviour: as integrators, they embed nutrition within institutional routines, information flows and care pathways; as connectors, they strengthen relationships across health, social, education, and food system actors; and as advocates, they shape organisational priorities and policy agendas related to equity, sustainability, and health. The analysis identifies enabling conditions, including supportive organisational structures, intersectoral collaboration, relevant policy frameworks and enhanced competencies in systems thinking and equity. It also notes common constraints such as siloed systems, workload pressures and role overload. Several leverage points emerge where targeted action can exert significant system-level impact (e.g. through changes in care-pathway information flows or links to community food resources). Recognising and consolidating these system-building roles can enhance the visibility, legitimacy and effectiveness of dietitians' contributions. A systems-oriented professional identity, supported by education, practice environments and policy infrastructures, can strengthen the profession's ability to influence the conditions shaping dietary behaviour, equity and sustainability.
