Corporate political activity in the context of unhealthy food advertising restrictions across Transport for London: A qualitative case study.

BACKGROUND: Diets with high proportions of foods high in fat, sugar, and/or salt (HFSS) contribute to malnutrition and rising rates of childhood obesity, with effects throughout the life course. Given compelling evidence on the detrimental impact HFSS advertising has on children's diets, the World Health Organization unequivocally supports the adoption of restrictions on HFSS marketing and advertising. In February 2019, the Greater London Authority introduced novel restrictions on HFSS advertising across Transport for London (TfL), one of the most valuable out-of-home advertising estates. In this study, we examined whether and how commercial actors attempted to influence the development of these advertising restrictions. METHODS AND FINDINGS: Using requests under the Freedom of Information Act, we obtained industry responses to the London Food Strategy consultation, correspondence between officials and key industry actors, and information on meetings. We used an existing model of corporate political activity, the Policy Dystopia Model, to systematically analyse arguments and activities used to counter the policy. The majority of food and advertising industry consultation respondents opposed the proposed advertising restrictions, many promoting voluntary approaches instead. Industry actors who supported the policy were predominantly smaller businesses. To oppose the policy, industry respondents deployed a range of strategies. They exaggerated potential costs and underplayed potential benefits of the policy, for instance, warning of negative economic consequences and questioning the evidence underlying the proposal. Despite challenging the evidence for the policy, they offered little evidence in support of their own claims. Commercial actors had significant access to the policy process and officials through the consultation and numerous meetings, yet attempted to increase access, for example, in applying to join the London Child Obesity Taskforce and inviting its members to events. They also employed coalition management, engaging directly and through business associations to amplify their arguments. Some advertising industry actors also raised the potential of legal challenges. The key limitation of this study is that our data focused on industry-policymaker interactions; thus, our findings are unable to present a comprehensive picture of political activity. CONCLUSIONS: In this study, we identified substantial opposition from food and advertising industry actors to the TfL advertising restrictions. We mapped arguments and activities used to oppose the policy, which might help other public authorities anticipate industry efforts to prevent similar restrictions in HFSS advertising. Given the potential consequences of commercial influence in these kinds of policy spaces, public bodies should consider how they engage with industry actors.

Development of a System Dynamics Model to Guide Retail Food Store Policies in Baltimore City.

Policy interventions to improve food access and address the obesity epidemic among disadvantaged populations are becoming more common throughout the United States. In Baltimore MD, corner stores are a frequently used source of food for low-income populations, but these stores often do not provide a range of affordable healthy foods. This research study aimed to assist city policy makers as they considered implementing a Staple Food Ordinance (SFO) that would require small stores to provide a range and depth of stock of healthy foods. A System Dynamics (SD) model was built to simulate the complex Baltimore food environment and produce optimal values for key decision variables in SFO planning. A web-based application was created for users to access this model to optimize future SFOs, and to test out different options. Four versions of potential SFOs were simulated using this application and the advantages and drawbacks of each SFO are discussed based on the simulation results. These simulations show that a well-designed SFO has the potential to reduce staple food costs, increase corner store profits, reduce food waste, and expand the market for heathy staple foods.

Are the Eatwell Guide and Nutrient Profiling Models Consistent in the UK?

A nutrient profiling model (NPM) was developed in 2005 in the UK to regulate the marketing of foods to children. It was revised in 2018, but the new version has not been finalised. The Eatwell Guide (EWG) is the UK's official food-based dietary guidelines. The aim of this study was to evaluate the agreement between the 2005 and 2018 versions of the NPM and the EWG. Using recent National Diet and Nutrition Surveys, we estimated the healthiness of individual diets based on an EWG dietary score and a NPM dietary index. We then compared the percentage of agreement and Cohen's kappa for each combination of the EWG score and NPM index across the range of observed values for the 2005 and 2018 versions. A total of 3028 individual diets were assessed. Individuals with a higher (i.e., healthier) EWG score consumed a diet with, on average, a lower (i.e., healthier) NPM index both for the 2005 and 2018 versions. Overall, there was good agreement between the EWG score and the NPM dietary index at assessing the healthiness of representative diets of the UK population, when a low cut-off for the NPM dietary index was used, irrespective of the version. This suggests that dietary advice to the public is broadly aligned with NPM-based food policies and vice-versa.

The WHO South-East Asia Region Nutrient Profile Model Is Quite Appropriate for India: An Exploration of 31,516 Food Products.

The rapid rise in prevalence of overweight/obesity, as well as high prevalence of type 2 diabetes and other nutrition-related noncommunicable diseases, has led the Food Safety and Standards Authority of India (FSSAI) to propose a front-of-package labeling (FOPL) regulation. An effective FOPL system applies a nutrient profile model that identifies foods high in sugar, sodium, and saturated fat that would receive a warning label for consumers to effectively discern between more and less healthy foods. Previous Nutrition Alchemy data collected by the food industry (n = 1306 products) estimated that approximately 96% of foods in India would have at least one warning label based on the FSSAI proposed FOPL. This near universal coverage of warning labels may be inaccurate and misleading. To address this, the current study compared two nutrient profile models, the WHO South-East Asia Region Organization (SEARO) and the Chilean Warning Octagon (CWO) Phase 3, applied to food products available in the Indian market from 2015-2020, collected through Mintel Global New Products Database (n = 10,501 products). Results suggest that 68% of foods and beverages would have at least one ' high-in' level warning label. This study highlights the need to include a more comprehensive sample of food products for assessing the value of warning labels.

School nutrition laws in the US: do they influence obesity among youth in a racially/ethnically diverse state?

BACKGROUND/OBJECTIVES: Little is known about the separate or combined effects of state and national nutrition policies regulating food and beverages in schools on child overweight/obesity (OV/OB) and related racial/ethnic disparities. We investigated the influence of school nutrition policies enacted in California, independently and in combination with the United States' national policy "Healthy Hunger Free Kids Act" (HHFKA) on childhood OV/OB and racial/ethnic disparities. SUBJECTS/METHODS: An interrupted time series design was used with data from 12,363,089 child-level records on 5th- and 7th-graders in California public schools to estimate sex- and racial/ethnic-specific time trends in OV/OB prevalence during three periods: before the California nutrition policies (2002-2004); when only California policies were in effect (2005-2012); and when they were in effect simultaneously with HHFKA (2013-2016). RESULTS: Before the state's policies, OV/OB prevalence increased annually among children in most subgroups. Improvements in OV/OB trends were observed for almost all groups after the California policies were in effect, with further improvements after the addition of HFFKA. The total change in annual log-odds of OV/OB, comparing the periods with both state and federal policies versus no policies, ranged from -0.08 to -0.01 and varied by grade, sex, and race/ethnicity. Within each sex and grade, the greatest changes were among African-American (-0.08 to -0.02, all p < 0.05) followed by Latino children (-0.06 to -0.01, all p < 0.05). Although disparities narrowed among these groups versus White children after the dual policy period, disparities remained large. CONCLUSIONS: State and national nutrition policies for schools may have contributed to containing the upward trend in childhood OV/OB and racial/ethnic OV/OB disparities within California. However, sizable OV/OB prevalence and disparities persist. To end the epidemic, promote healthy weight and increase health equity, future efforts should strengthen state and national policies to improve food quality in schools, particularly those serving populations with the highest OV/OB prevalence.

Beyond Nutrient Deficiency-Opportunities to Improve Nutritional Status and Promote Health Modernizing DRIs and Supplementation Recommendations.

The US Dietary Guidelines for Americans (DGA) provide dietary recommendations to meet nutrient needs, promote health, and prevent disease. Despite 40 years of DGA, the prevalence of under-consumed nutrients continues in the US and globally, although dietary supplement use can help to fill shortfalls. Nutrient recommendations are based on Dietary Reference Intakes (DRIs) to meet the nutrient requirements for nearly all (97 to 98 percent) healthy individuals in a particular life stage and gender group and many need to be updated using current evidence. There is an opportunity to modernize vitamin and mineral intake recommendations based on biomarker or surrogate endpoint levels needed to 'prevent deficiency' with DRIs based on ranges of biomarker or surrogate endpoints levels that support normal cell/organ/tissue function in healthy individuals, and to establish DRIs for bioactive compounds. We recommend vitamin K and Mg DRIs be updated and DRIs be established for lutein and eicosapentaenoic and docosahexaenoic acid (EPA + DHA). With increasing interest in personalized (or precision) nutrition, we propose greater research investment in validating biomarkers and metabolic health measures and the development and use of inexpensive diagnostic devices. Data generated from such approaches will help elucidate optimal nutrient status, provide objective evaluations of an individual's nutritional status, and serve to provide personalized nutrition guidance.

Towards unified and impactful policies to reduce ultra-processed food consumption and promote healthier eating.

The global surges in obesity and nutrition-related non-communicable diseases (NCDs) have created a need for decisive new food policy initiatives. A major concern has been the impact of ultra-processed foods (UPFs) and ultra-processed drinks on weight gain and on the risk of several NCDs. These foods, generally high in calories, added sugar, sodium, and unhealthy fats, and poor in fibre, protein, and micronutrients, have extensive negative effects on human health and on the environment (due to their associated carbon emission and water use). There is a growing tendency worldwide, and especially in South America, for food companies to add micronutrients to UPFs to make health claims regarding these products, to which food-regulating authorities refer to fake foods. Although more than 45 countries and smaller subregional or urban entities have created taxes on ultra-processed drinks, such as sugar-sweetened beverages, only a few have adopted taxes on snacks and other UPFs, and none have added major subsidies for truly healthy, fresh or minimally processed food for people from lower socioeconomic backgrounds. Another major focus has been on developing effective package labelling. A smaller number of countries have selected the most impactful warning labels and linked them with other measures to create a mutually reinforcing set of policies; a few other countries have developed effective school food policies. We herein present in-depth results from key countries involved in all these actions and in comprehensive marketing controls, and conclude with our recommendations for the future. This field is quite new; progress to date is substantial, but much more is left to learn.

Stakeholder interactions with the federal government related to Bill S-228 and marketing to kids in Canada: a quantitative descriptive study.

BACKGROUND: Canadian federal restrictions on food marketing to children (children's marketing) were proposed in 2016 as Bill S-228, the Child Health Protection Act, which subsequently died on the parliamentary table. This study quantified the interactions (meetings, correspondence and lobbying) related to Bill S-228 and children's marketing by different stakeholders with the federal government. METHODS: Interactions between all stakeholders and government related to children's marketing and Bill S-228 (Sept. 1, 2016-Sept. 30, 2019) were analyzed. These included the "Meetings and correspondence on healthy eating" database, detailing interactions between stakeholders and Health Canada related to nutrition policies; and Canada's Registry of Lobbyists, reporting activities of paid lobbyists. We categorized the interactions by stakeholder type (industry, nonindustry and mixed), and analyzed the number and type of interactions with different government offices. RESULTS: We analyzed 139 meetings, 65 lobbying registrants, 215 lobbying registrations and 3418 communications related to children's marketing and Bill S-228. Most interactions were from industry stakeholders, including 84.2% of meetings (117/139), 81.5% of lobbying registrants (53/65), 83.3% of lobbying registrations (179/215) and 83.9% of communications (2866/3418). Most interactions (> 80%) in the highest-ranking government offices were by industry. INTERPRETATION: Industry stakeholders interacted with government more often, more broadly and with higher ranking offices than nonindustry stakeholders on subjects related to children's marketing and Bill S-228. Although further research is needed to analyze the nature of the discourse around children's marketing, it is apparent that industry viewpoints were more prominent than those of nonindustry stakeholders.

Tracking Progress from Policy Development to Implementation: A Case Study on Adoption of Mandatory Regulation for Nutrition Labelling in Malaysia.

Mandatory nutrition labelling, introduced in Malaysia in 2003, received a "medium implementation" rating from public health experts when previously benchmarked against international best practices by our group. The rating prompted this qualitative case study to explore barriers and facilitators during the policy process. Methods incorporated semi-structured interviews supplemented with cited documents and historical mapping of local and international directions up to 2017. Case participants held senior positions in the Federal government (n = 6), food industry (n = 3) and civil society representations (n = 3). Historical mapping revealed that international directions stimulated policy processes in Malaysia but policy inertia caused implementation gaps. Barriers hindering policy processes included lack of resources, governance complexity, lack of monitoring, technical challenges, policy characteristics linked to costing, lack of sustained efforts in policy advocacy, implementer characteristics and/or industry resistance, including corporate political activities (e.g., lobbying, policy substitution). Facilitators to the policy processes were resource maximization, leadership, stakeholder partnerships or support, policy windows and industry engagement or support. Progressing policy implementation required stronger leadership, resources, inter-ministerial coordination, advocacy partnerships and an accountability monitoring system. This study provides insights for national and global policy entrepreneurs when formulating strategies towards fostering healthy food environments.

Food Insecurity Among College Students: An Analysis of US State Legislation Through 2020.

Many US college students experience food insecurity (FI). Given most students are excluded from receiving federal nutrition assistance, additional efforts are needed to alleviate student FI. This perspective discusses proposed and enacted state statutes, resolutions, and bills addressing college FI to date, which range in depth, breadth, and success. Overall, states have demonstrated their promising role in addressing FI; however, college FI promises to be a continuing challenge, particularly given continued widespread unemployment that began with the onset of coronavirus disease 2019 and the global struggle for economic recovery.

Alignment of State Regulations With Breastfeeding and Beverage Best Practices for Childcare Centers and Family Childcare Homes, United States.

OBJECTIVES: Childcare is an important setting for nutrition; nearly half of young children in the United States participate in licensed childcare, where they consume up to two-thirds of their daily dietary intake. We compared state regulations for childcare with best practices to support breastfeeding and healthy beverage provision. METHODS: We reviewed regulations for childcare centers (centers) and family childcare homes (homes) in effect May-July 2016 and rated all 50 states for inclusion (1 = not included, 2 = partially included, 3 = fully included) of 12 breastfeeding and beverage best practices. We calculated average ratings for 6 practices specific to infants aged 0-11 months, 6 practices specific to children aged 1-6 years, and all 12 practices, by state and across all states. We assessed significant differences between centers and homes for each best practice by using McNemar-Bowker tests for symmetry, and we assessed differences across states by using paired student t tests. RESULTS: States included best practices in regulations for centers more often than for homes. Average ratings (standard deviations) in regulations across all states were significantly higher in centers than in homes for infant best practices (2.1 [0.5] vs 1.8 [0.5], P < .001), child best practices (2.1 [0.6] vs 1.8 [0.6], P = .002), and all 12 best practices combined (2.1 [0.5] vs 1.8 [0.6], P < .001). CONCLUSIONS: Although best practices were more consistently included in regulations for centers than for homes, many state childcare regulations did not include best practices to support breastfeeding and the provision of healthy beverages. Findings can be used to inform efforts to improve regulations and to reduce differences between centers and homes.

Wisconsin School Wellness Policies after Federal Legislation Change: Understanding Key Mechanisms of Policy Improvement.

BACKGROUND: The Final Rule of the Healthy Hunger Free Kids Act, published in 2016, required school districts participating in the federal Child Nutrition Programs to update their local wellness policies to reflect the more stringent requirements effective June 30, 2017. OBJECTIVE: Our aim was to investigate whether Wisconsin school wellness policies (SWPs) were updated after the Final Rule, measure policy quality change, and describe mechanisms of successful policy change. DESIGN: From 2016 through 2018, an explanatory sequential mixed-methods study examined change in SWP quality before and after the Final Rule was published. SWPs were collected in 2 waves reflecting policies written before and updated after the July 21, 2016 publication of the Final Rule. Semi-structured key-informant interviews were conducted with districts that demonstrated significant policy improvement. PARTICIPANTS/SETTING: Quantitative analysis examined 442 Wisconsin school districts' SWPs. Semi-structured interviews were conducted with 14 school districts that demonstrated significant change between waves. MAIN OUTCOME MEASURES: WellSAT 2.0 strength and comprehensiveness scores measured SWP quality among districts that updated their policies. Themes from interviews were identified using framework analysis. STATISTICAL ANALYSIS PERFORMED: First, we calculated the proportion of Wisconsin school districts participating in federal Child Nutrition Programs for which SWPs were obtained at both waves of policy collection (n = 192 districts, 43.4%). Among districts that updated SWPs in wave II, repeated-measure analysis of variance tests described policy quality and policy quality change, respectively. RESULTS: Among the 192 districts that updated their SWPs, policy quality increased overall and for 5 of 6 domains. Nutrition education scores did not show significant change. Interviewees commonly cited wellness leadership, support and resources, and buy-in and culture change as key components of policy improvement. CONCLUSIONS: Fewer than half of Wisconsin school districts updated their policies in the 10 months after the Final Rule was published. SWP from these districts showed policy quality improvement in most areas. Interviews with successful districts indicate the common need for empowered leaders and supportive environments to facilitate culture change around student wellness.

Recomendações alimentares e nutricionais para o Programa Nacional de Alimentação Escolar: uma análise da história recente / Food and nutritional recommendations for the National School Feeding Program: an analysis of recent history

Introdução: O Programa Nacional de Alimentação Escolar (PNAE) é a iniciativa mais antiga do governo brasileiro na área de alimentação escolar e Segurança Alimentar e Nutricional, sendo o mais abrangente do mundo em relação ao atendimento de escolares e à garantia do Direito Humano à Alimentação Adequada e Saudável. Objetivo: Analisar as recomendações alimentares e nutricionais estabelecidas para o PNAE no período de 2009-2020. Método: Foi realizada uma busca on-line por documentos e legislações que tratavam da temática no site do Fundo Nacional de Desenvolvimento da Educação (FNDE). Além disso, foram utilizados materiais resultantes de pesquisas realizadas na Biblioteca Virtual de Saúde (BVS-BIREME) e Google Acadêmico. Resultado: O PNAE tem sido marcado por avanços em relação à gestão e operacionalização, sendo a descentralização um processo que possibilitou a redução da oferta de alimentos processados e ultraprocessados na alimentação escolar. O ano de 2009 é um marco histórico para as recomendações alimentares e nutricionais, tendo em vista a obrigatoriedade, imposta pela Lei Federal n. 11.947/2009, de aquisição de alimentos oriundos da agricultura familiar para a alimentação escolar. Essa determinação foi reforçada pela Resolução CD/FNDE n. 38/2009, juntamente com a ampliação e o detalhamento sobre recomendações nutricionais e alimentares para o PNAE, sendo sucedida pelas Resoluções CD/FNDE n. 26/2013 e CD/FNDE n. 06/2020. Conclusão: Com base no processo avaliativo e comparativo da evolução das recomendações nutricionais do PNAE, é possível afirmar que a evolução ocorreu na medida em que o perfil de consumo alimentar e o estado nutricional da população brasileira foram se modificando. (AU)

Introduction: The National School Feeding Program (PNAE) is the oldest initiative of the Brazilian government in the area of school feeding and Food and Nutritional Security, being the most comprehensive in the world with respect to the care of schoolchildren and the guarantee of the Human Right to Adequate and Healthy Feeding. Objective: To analyze the food and nutritional recommendations established for the PNAE in the period 2009-2020. Method: An online search for documents and legislation dealing with the topic was conducted on the website of the National Fund for Educational Development (FNDE). In addition, materials resulting from research conducted on the Virtual Health Library (VHL-BIREME) and Google Academic were used. Result: The PNAE has been marked by advances in management and operationalization, where decentralization is a process that has made it possible to reduce the supply of processed and ultra-processed food in school feeding. The year 2009 is a milestone for food and nutritional recommendations, in view of the obligation, imposed by Federal Law n. 11.947/2009, to purchase food from family agriculture for school feeding. This determination was reinforced by Resolution CD/FNDE n. 38/2009, together with the expansion and detailing on nutritional and food recommendations for the PNAE, and was succeeded by Resolutions CD/FNDE n. 26/2013 and CD/FNDE n. 06/2020. Conclusion: Based on the evaluation and comparative process of the evolution of nutritional recommendations of the PNAE, it is possible to affirm that the evolution took place as the profile of food consumption and the nutritional status of the Brazilian population were changing.

Association between Nutrition Policies and Student Body Mass Index.

In response to concerns about childhood obesity, many US states have implemented policies to limit the sale of unhealthy foods and beverages (e.g., snacks, desserts, and sugary drinks) sold in competition with school meal programs (i.e., competitive foods) in order to improve the nutritional environment of schools and support student health. This study measured state-level competitive food and beverage policies that require foods and beverages sold in à la carte lines, vending machines, and school stores to meet strong nutrition standards and tested the hypothesis that students living in states with stronger laws would have lower body mass index (BMI)-for-age percentiles. BMI data from a national sample of 1625 students attending 284 schools from the School Nutrition and Meal Cost Study were linked to state laws coded as part of the National Wellness Policy Study. A survey-adjusted linear regression model accounting for student and school-level characteristics showed that stronger state nutrition policies were associated with lower student BMI scores (coefficient: -0.06, 95% CI: -0.12, -0.00). Additional models indicated that stronger state policies were significantly associated with fewer unhealthy foods and beverages available in schools. These findings suggest that strong regulations on competitive foods and beverages may lead to improvements in the nutritional quality of the school environment and student BMI. Thus, current federal standards regulating snacks in US schools (i.e., Smart Snacks) are an important element of a comprehensive strategy to improve the school nutrition environment and reduce rates of childhood obesity.
