The triple burden of malnutrition is growing in low- and middle-income countries (LMICs). Increasing access to affordable ultra-processed foods in the food environment is contributing to this problem. While existing explanations for this triple burden of malnutrition have examined demand-side factors of food choices, the supply-side policies relating to the food environment drivers, ideas and actors’ interests have been neglected. Using a case study of Ghana, this analysis combines the Advocacy Coalition Framework with the narrative policy analysis to unpack the supply-side food environment policies and actors driving the triple burden of malnutrition. Applying a mixed methods analysis of the transcripts, the narratives reveal public, private and civil society organization (CSO) coalitions with different ideas and interests in the food environment.
