Capturing the moment: a snapshot review of contemporary food environment research featuring participatory photography methods
(Current Opinion in Environmental Sustainability, 2023) Turner, C.; Salm, L.; Laar, A.; et al.
This snapshot review captures recent advances in the use of participatory photography methods within food environment research, featuring 28 peer-reviewed articles published between 2020 and 2022. Records were retrieved from a systematic search of the databases PubMed and Scopus. Studies featured high income (64%) and low- and middle-income countries (36%). Local and school food environments were common focal sites, with studies typically investigating how food environments influence food acquisition and consumption practices among adult and adolescent consumers. Photovoice was the dominant methodological framing (71%), although we found substantial variation in study designs, camera devices and degree of participation. Going forward, we encourage researchers and practitioners to revisit the roots of participatory photography as a participatory action research strategy, to engage participants as agents of change in their food environment in support of the sustainable transformation of food systems and improved diets, nutrition and health.
Food systems thinking unpacked: a scoping review on industrial diets among adolescents in Ghana
(Food Security, 2023) Sambu, W.C.; Picchioni, F.; Stevano, S.; Codjoe, E.A.; Nkegbe, P.K.; Turner, C.
Unhealthy diets are among the main risk factors associated with non-communicable diseases (NCDs). In Sub Saharan Africa, NCDs were responsible for 37% of deaths in 2019, rising from 24% in 2000. There is an increasing emphasis on health harming industrial foods, such as ultra-processed foods (UPFs), in driving the incidence of diet-related NCDs. However, there is a methodological gap in food systems research to adequately account for the processes and actors that shape UPFs consumption across the diferent domains of the food systems framework and macro-meso-micro levels of analysis. This paper interrogates how the Food Systems Framework for Improved Nutrition (HLPE in Nutrition and food systems. A report by the high level panel of experts on food security and nutrition of the committee on world food security, 2017), considered the dominant framework to analyse nutrition, and language of interdisciplinarity are practised in research with regards to consumption of UPFs among adolescents in Ghana, a population group that is often at the forefront of dramatic shifts in diets and lifestyles. We conducted a scoping review of studies published between 2010 and February 2022, retrieved 25 studies, and mapped the fndings against the domains and analysis levels of the Food Systems Framework for Improved Nutrition (HLPE in Nutrition and food systems. A report by the high level panel of experts on food security and nutrition of the committee on world food security, 2017). Our study illustrates that there is a tendency to address unhealthy diets among adolescents in a siloed manner, and as a behavioural and nutritional issue. In most cases, the analyses fail to show how domains of the food systems framework are connected and do not account for linkages across diferent levels of analysis. Methodologically, there is a quantitative bias. From the policy point of view, there is a disconnect between national food policies and food governance (i.e., trade and regulations) and initiatives and measures specifcally targeted at adolescent’s food environments and the drivers of UPFs consumption.
