Food insecurity impacts millions of people globally. It has been recognized as a priority and a human right by the United Nations where empowerment of women is identified as a significant goal in addressing food insecurity. In the Maritime Province of Nova Scotia (NS), Canada, more than one in five children live in food insecure households. Since 2002, participatory action research (PAR) has been an integral component of food costing in NS with an aim to support capacity building for food security. Building on earlier research that examined short-term outcomes, and recognizing a lack of research examining outcomes of PAR processes, this study aimed to explore the medium-term individual capacity building processes and outcomes of women involved in Participatory Food Costing (PFC). Findings revealed that capacities were built with respect to interrelated themes of ‘awareness, participation, personal development, readiness to change, political impact, influence on others, self-esteem, project growth and project continuity’. In addition, the involvement of these women in PFC resulted in both personal empowerment and food security-related policy change. Involving vulnerable populations through PAR is valuable in influencing health-related policy.
