Front-of-package (FOP) labels have been adopted in many countries to battle the obesity pandemic and its serious health consequences by providing clearer and easier-to-understand nutrition and health information. The effectiveness of FOP labels has been generally confirmed, with some contextual and individual factors modifying their effectiveness. Existing theories (eg, the dual-process theory) and shifting priorities for self-control, provide some explanations for the FOP label effect. However, the cognitive and neural mechanisms underlying the processing of FOP labels remain unknown. Here, a new model, namely, the neural model of FOP label processing, has been proposed to fill this gap by providing an integrated account of FOP label processing while simultaneously considering multiple important situational and individual factors in the same framework. This neural model is built on the core eating network (ie, the ventral reward pathway and the dorsal control pathway) for food cue processing and actual food consumption. The new model explains how FOP labels may facilitate attention, influence the core eating network, and thus alter food choices. It also demonstrates how motivation may modify FOP label processing in 2 ways: affecting attention (the indirect way) and changing the process of evaluating the food (the direct way). It further explains how some contextual and individual factors (eg, ego depletion, time pressure, and health knowledge) influence the process. Thus, the neural model integrates evidence from behavioral, eye-tracking, and neuroimaging studies into a single, integrated account, deepening understanding of the cognitive and neural mechanisms of FOP label processing. This model might facilitate consensus on the most successful FOP label. Moreover, it could provide insights for consumers, food industries, and policy makers and encourage healthy eating behaviors.

Restrictions on marketing of unhealthy foods and beverages to children is a globally recommended policy measure to improve diets and health. The aim of the analysis was to identify opportunities to enable policy learning and shift beliefs of relevant actors, to engender policy progress on restrictions on marketing of unhealthy foods to children. We drew on the Advocacy Coalition Framework to thematically analyse data from qualitative policy interviews conducted Australia (n  = 24), Fiji (n  = 10) and Thailand (n  = 20). In all three countries two clear and opposing advocacy coalitions were evident within the policy subsystem related to regulation of unhealthy food marketing, which we termed the 'strengthen regulation' and 'minimal/self regulation' coalitions. Contributors to policy stasis on this issue were identified as tensions between public health and economic objectives of government, and limited formal and informal spaces for productive dialogue. The analysis also identified opportunities for policy learning that could enable policy progress on restrictions on marketing of unhealthy foods to children as: taking an incremental approach to policy change, defining permitted (rather than restricted) foods, investing in new public health expertise related to emerging marketing approaches and scaling up of monitoring of impacts. The insights from this study are likely to be relevant to many countries seeking to strengthen regulation of marketing to children, in response to recent global recommendations.

Background Food industry led reformulation efforts have attempted to address the prevalence of obesity by modifying nutrient compositions in food products. This study explored progress in nutrient composition alterations in products in Irish supermarkets by comparing the nutrient labels of products sold in 2014 and 2017. Methods We conducted two supermarket audits in 2014 and 2017 to examine the changes in the nutrient profile of cereals, breads, spreads, unflavoured milks, yogurts and juices. Information on the nutrients of interest to the study (energy, protein, fat, carbohydrate, saturated fat, salt, sugar and some micronutrients) were extracted and stored in Microsoft Excel. The nutrient profile of each product was compared across the two timepoints. Our study shows that the mean level of sugars in cereals remains high and that the mean level of salt remains high in cereals, breads, and spreads. Results In total, 143 products were directly compared (86 cereals, 26 breads, 17 spreads and 14 milks). Our study shows that the composition of salt and sugar in cereal, bread, spreads and milk has declined by 12 and 7%, respectively. Saturated fat has declined in cereals (7%), but has increased in breads (12%), spreads (1%), and milks (5%). Manufacturers increased the serving sizes in nine cereals and one milk. Conclusions From a population health perspective, the results are encouraging but care should be exercised by the food industry not to allow total fat and saturated fat levels to creep upwards. Further research and engagement of public health specialists and the food industry are needed. [ABSTRACT FROM AUTHOR]

Practitioners need to engage with the contested nature of public health policymaking. This study, stemming from a concern that the involvement of Big Food is not widely problematized in health promotion practice, used 'What's the Problem Represented to Be?' discourse analysis to examine how Big Food, as a discursive actor, reacted to and shaped a problem representation of childhood obesity. Analysis of Big Food documents, including Coca-Cola and Burger King, developed during the regulation of broadcast advertising to children in Ireland found that Big Food constructs the problem of childhood obesity in a way which privileges its role as policy actor; it draws on and undermines public health discourses of obesity; and it negates the impact of corporate practices on obesity and on related policymaking. An in-depth analysis of Big Food's own documents provides access to the processes of knowledge production and governing undertaken by Big Food. The study offers two tools of resistance for health promotion practitioners to interrogate and challenge Big Food—problematization as a policy tool and 'corporate influence' as a critical public health discourse.

Obesity and diet-related health problems are complex, multi-factorial issues. Individual food choices are shaped by the wider context, and food environment level change is needed to support individual behaviour change. The food service sector can play an integral role, changing aspects of the food environment and contributing to improved consumer health. This systematic review aimed to analyse food service schemes that aimed to improve consumer health. Ten electronic databases were systematically searched to identify articles, supplemented with checking of reference lists from similar reviews and forward and backward searches to identify articles describing food service sector schemes. Sixteen schemes were identified, documented in 36 articles/reports. The schemes aimed to improve consumer health through one of three approaches— informing , enabling or engineering. In this order, these approaches involved increasing levels of effort from food services, corresponding with decreasing levels of effort for consumers. Half the schemes were informing , relying on an informed consumer to make a healthy choice. Most informing schemes had been evaluated to determine their impact on consumer choice and/or health, the evidence showed these schemes were generally ineffective. The effect of the enabling or engineering schemes on consumer choice and health had not been measured. Instead, evaluations focussed on process or business engagement rather than behavioural change assessments. This review indicates the food sector has the potential to contribute to consumer health through enabling and engineering ; however, detailed outcome assessments are needed to draw definitive conclusions.
