Junk-food marketing contributes significantly to childhood obesity, which in turn imposes major health and economic burdens. Despite this, political priority for addressing junk-food marketing has been weak in many countries. Competing interests, worldviews and beliefs of stakeholders involved with the issue contribute to this political inertia. An integral group of actors for driving policy change are parliamentarians, who champion policy and enact legislation. However, how parliamentarians interpret and portray (i.e. frame) the causes and solutions of public health nutrition problems is poorly understood. The present study aimed to understand how Australian parliamentarians from different political parties frame the problem of junk-food marketing.

Framing analysis of transcripts from the Australian Government’s Parliamentary Hansard, involving development of a theoretical framework, data collection, coding transcripts and thematic synthesis of results.

Australia.

None.

Parliamentarian framing generally reflected political party ideology. Liberal parliamentarians called for minimal government regulation and greater personal responsibility, reflecting the party’s core values of liberalism and neoliberalism. Greens parliamentarians framed the issue as systemic, highlighting the need for government intervention and reflecting the core party value of social justice. Labor parliamentarians used both frames at varying times.

Parliamentarians’ framing was generally consistent with their party ideology, though subject to changes over time. This project provides insights into the role of framing and ideology in shaping public health policy responses and may inform communication strategies for nutrition advocates. Advocates might consider using frames that resonate with the ideologies of different political parties and adapting these over time.

To define a generic diet to protect human health and food system sustainability based on three dimensions: animal:plant ratio, degree of food processing and food diversity.

The percentages of maximum animal and ultra-processed energy content were evaluated from scientific papers (Web of Science database) and reports from international scientific institutions. Then, a weekly French standard diet, including these percentages and food diversity (≥42 different foods), was designed to calculate adequacy to nutritional needs.

Based on traditional and scientifically based healthy diets, and on foresight scenarios for sustainable diets at horizon 2050, a median daily animal energy content intake of 15 % was found to be protective towards both human health and environment. Based on epidemiological studies associating ultra-processed energy consumption with increased overweight/obesity risk, a precautionary threshold of approximately 15 % ultra-processed energy content was observed. The French diet allows addressing all nutritional needs and other nutritional indicators such as maximum salt and simple sugar consumption, α-linolenic acid:linoleic acid ratio and essential amino acids. This diet was named the ‘3V rule’ for Végétal (plant), Vrai (real) and Varié (varied, if possible organic, local and seasonal). This generic diet can be adapted according to regional traditions and environmental characteristics. Excluding only one dimension of it would threaten both health and food system sustainability.

Tending towards a 3V-based diet, while respecting local constraints, should allow preserving human health, environment (greenhouse gas emissions, pollution, deforestation, etc.), small farmers, animal welfare and biodiversity, culinary traditions and socioeconomics (including an alleviation of public health cost).

National concerns over food insecurity and obesity have prompted legislation seeking to further restrict Supplemental Nutrition Assistance Program (SNAP) purchases. The objective of this study is to provide insight on the potential impact of proposed purchase restrictions by comparing SNAP participant and income-eligible non-participants’ expenditures on current SNAP-restricted foods, that is, hot foods, prepared foods, alcohol, vitamins and meal supplements.

Cross-sectional study. Bivariate analysis and multivariable regression analysis with an instrumental variables approach were employed to compare the probability of purchasing and expenditures on current SNAP-restricted foods among SNAP participants and income-eligible non-participants.

National Household Food Acquisition and Purchase Survey, 2012–2013.

2513 households, of which 1316 were SNAP participants and 1197 were income-eligible non-participants.

Both the share of households purchasing and household expenditures on current SNAP-restricted foods were similar among SNAP participants and income-eligible non-participants.

Results provide further empirical evidence that proposed SNAP purchase restrictions on sugar-sweetened beverages, snack foods and luxury foods are unlikely to have a meaningful effect on SNAP household food purchases.

To explore factors that minimize lunch waste in Tokyo elementary schools and to consider how such factors can be modified and applied in US schools.

Focused ethnographic study using interviews, observation, participant observation and document review. Data were analysed using thematic analysis.

Tokyo, Japan.

Five school dietitians participated in the study. Data collection methods included in-depth interviews, observation of nutrition education lessons, participant observation of school lunchtime and review of relevant school documents (e.g. lunch menus, food waste records).

Five themes emerged from the analysis: (i) reinforcement of social norms to eat without waste; (ii) menu planning to increase exposure to unfamiliar and/or disliked foods; (iii) integration of food and nutrition education into the school curriculum; (iv) teacher lunchtime practices related to portion sizes, distributing leftover food and time management; and (v) engagement of students in reducing school lunch waste. Practical and tangible applications to US schools include measuring and reporting lunch waste to influence social norms, teaching students about the importance of reducing food waste, offering flexible school lunch portion sizes and providing students with meaningful opportunities to contribute to solving the problem of school lunch waste.

Japan offers a model for minimizing school lunch waste through a holistic approach that includes factors that operate at and interact across multiple levels of society. Modifying and applying such an approach in US schools is worth considering given the urgent need to address food waste in order to support healthy diets and sustainable food systems.
