Mapping the digital food environment: A scoping review protocol

Introduction Food environments are the interface through which people interact with the broader food system. They are a key determinant of healthy and sustainable diets. The widespread use of digital technology in late modernity and the shift towards a digital society have posed new challenges for nutrition and health, with a concomitant surge in research on social media, digital health promotion interventions, and more recently, increasing interest in digital food marketing. While the literature is abundant on studies linking food, nutrition and digital technology, the effort to conceptualise and describe the digital food environment is new. This scoping review aims to support the development of a definition of the digital food environment and characterise it, along with key thematic research trends on this topic and potential consequences for nutrition and health. Methods and analysis The planned scoping review will be supported by the methodological framework proposed by Arksey and O’Malley and further developed by Levac et al. Development and reporting will follow the Preferred Reporting Items for Systematic Reviews and MetaAnalyses—Extension for Scoping Reviews (PRISMA-ScR) checklist and guidelines. The development of the search strategy was guided by the food environment conceptual framework developed by Turner et al. Four databases will be searched: MEDLINE, EMBASE, Scopus and Web of Science. Citation searching will be applied to identify additional studies, through checking of reference lists of primary studies and reviews. Studies in English, published from the year 2000 onwards, will be included. No geographical or population limits will be applied. Data will be extracted and analysed using a standardised charting tool. Ethics and dissemination No ethical approval is required for this study. The results will be submitted to an international peer-reviewed journal and scientific conferences. They will be disseminated through digital science communication platforms, including academic social media, to amplify its reach and usefulness.publishedVersio

The potential of food environment policies to reduce socioeconomic inequalities in diets and to improve healthy diets among lower socioeconomic groups: an umbrella review

Socioeconomic inequalities in diets need to be tackled to improve population diets and prevent obesity and diet-related non-communicable diseases. The potential of food environment policies to reduce such inequalities has to date however not been appraised. The objective of this umbrella review was to assess the impact of food environment policies on socioeconomic inequalities in diets and to identify knowledge gaps in the existing literature, using the Healthy Food Environment Policy Index as a conceptual framework. The policies considered in the umbrella review are within six domains: 1) food composition 2) food labelling 3) food promotion 4) food provision 5) food retail 6) food pricing. A systematic search for systematic literature reviews on the effect of food environment policies on dietary-related outcomes across socioeconomic groups and published in English between 2004 and 2019 was conducted. Sixteen systematic literature reviews encompassing 159 primary studies were included, covering food composition (n = 2), food labelling (n = 3), food provision (n = 2), food prices (n = 13) and food in retail (n = 4). Quality assessment using the “Assessing the Methodological Quality of Systematic Reviews” quality rating scale showed that review quality was mainly low or critically low. Results suggest that food taxation may reduce socioeconomic inequalities in diets. For all other policy areas, the evidence base was poor. Current research largely fails to provide good quality evidence on impacts of food environment policies on socioeconomic inequalities in diets. Research to fill this knowledge gap is urgently needed.publishedVersio

The potential of a human rights approach for accelerating the implementation of comprehensive restrictions on the marketing of unhealthy foods and non-alcoholic beverages to children

Overweight and obesity in children is rising at the global level, particularly in low- and middle-income countries. Among the causes for this increase is the marketing of unhealthy food and beverage products, which affects children’s food preferences, purchasing requests and consumption patterns. The need to address harmful marketing to children has been recognized at the World Health Organization, with Member States having agreed in 2010 to implement a set of recommendations to restrict such practices. Concurrently, there is an increasing understanding of unhealthy food and malnutrition as human rights concerns. This paper explores the potential of existing legally and non-legally binding human rights instruments for accelerating the implementation of comprehensive restrictions to reduce harmful marketing of unhealthy foods and beverages to children. Four relevant themes were identified in existing human rights instruments: (i) the best interest of the child should be considered above all other interests; (ii) the rights to health and adequate food cannot be realized without supportive healthy environments; (iii) children should be protected from economic exploitation; and (iv) the persuasive marketing of unhealthy food and beverage products is explicitly recognized as a threat to the rights to food and health. In conclusion, existing human rights instruments could be harnessed to advance public health measures to restrict the marketing of unhealthy food and beverage products to children. Policy-makers and advocates should draw from these instruments and refer to State’s obligations within international and domestic human rights law to strengthen their efforts to restrict harmful marketing practices to children
