Is there a healthy-food premium? A cross-sectional analysis of the UK online food delivery sector
Online food delivery (OFD) platforms account for a growing share of out-of-home meals, but their often poor nutritional quality may worsen diets and related health inequalities. Furthermore, pricing structures within this sector may be systematically incentivizing the selection of higher-calorie items. Using menu data collected in June 2023 from two major UK OFD platforms, this study examined 7392 unique adult menu items from large restaurant cha…
Designing fiscal policies for health and climate: Trade-offs, co-benefits and distributional effects in Great Britain
Current food systems contribute to poor diets, that are the leading global risk factor for ill health and premature mortality, while also accelerating climate change. We simulated demand responses to food taxes and subsidies in Great Britain assessing co-benefits and trade-offs across nutrition and environmental outcomes. Six co-created policy scenarios included taxes on less-healthy and higher-carbon foods, and subsidies for healthier, lower-car…
Characterising public opinion for food-based fiscal policies in the UK
Various fiscal policies have been proposed to incentivise healthy and sustainable diets, with differing proposed attributes and levels. Public support can influence the ability for such policies to be implemented but is currently poorly understood, so two discrete choice experiments (DCEs) were used to measure such preferences among 2,020 adults in the UK. The attributes and levels for 192 policy options were identified using a scoping review tha…
We should be focusing on why we eat, what we eat and how it makes us feel, not how many calories it has’: A photovoice study exploring young people’s views on the out-of-home calorie labelling policy …
Obesity is a complex problem, a perpetual challenge for governments to address. In 2022 as part of a government obesity strategy, a mandatory calorie labelling policy for out-of-home food sectors was implemented in England. Little is known about the impact of this policy on young people; therefore, this study explored young people views on the policy and their priorities for change in their local food environments. We conducted a participatory, q…
How did labelling provision on menus for online food delivery change after implementation of England's calorie labelling regulations
This study describes the provision of calorie labelling in the digital out-of-home food sector after the implementation of mandatory calorie labelling for large businesses in England in April 2022. Using online menu data from two major food delivery services between June 2022 and October 2023, the number of restaurants available for delivery and the share of restaurants displaying calories was determined for every neighbourhood (Lower layer Super…
Impact of calorie labelling on online takeaway food choices: An online Menu-Based Choice Experiment in England
Eating out-of-home is linked to higher calorie intake and body weight, risk factors for obesity, diabetes and other diseases. This study examined whether providing calorie information on online takeaway food menus leads to lower-calorie food choices. A Menu-based Choice Experiment was conducted in November 2022 among 1040 online takeaway consumers in England (Kantar's Worldpanel Out of Home Purchase Panel). Each participant chose their preferred …

Objective: To assess associations between self-reported advertising exposure to foods high in fats, salt and sugar and household purchases of energy, nutrients and specific product categories. Design: A cross-sectional design was used. Advertising exposure data were gathered using a questionnaire administered to the main shopper of each household, and purchase data from supermarkets and other stores for these households were accessed for a 4-week…
Changes in food and drink purchasing behaviour in England during the first 3 months of the Covid-19 pandemic: An interrupted time series analysis
Objective: This study examined changes food and drink purchasing during the first 3 months of the COVID-19 pandemic in England, and if changes varied by population subgroups. Design: We investigated changes in take-home food and drink purchasing and frequency of out-of-home (OOH) purchasing using an interrupted time series analysis design. The start of pandemic restrictions (the intervention) was defined as 16 March 2020, when first announced in …
Associations between the food environment and food and drink purchasing using large-scale commercial purchasing data: A cross-sectional study
Despite some evidence for exposure to OOH outlets and UPF purchases, this study finds limited evidence for the impact of the food environment on household food and drink purchasing. Nonetheless, region-specific effects regarding alcohol purchasing indicate the importance of geographical context for research and policy
Associations between area deprivation and changes in the digital food environment during the Covid-19 pandemic: Longitudinal analysis of three online food delivery platforms
Online food delivery services facilitate access to unhealthy foods and have proliferated during the COVID-19 pandemic. This study explores associations between neighbourhood deprivation and exposure to online food delivery services and changes in exposure by deprivation during the first year of the pandemic. Data on food outlets delivering to 661 postcode districts in London and the North of England in 2020 and 2021 were collected from three onli…
Like parent, like child: A cross-sectional study of intra-household consumption patterns of non-alcoholic beverages among British households with children
Objective: Most research investigating sugar-sweetened beverages (SSB) and health, conducted at the individual or household level, ignores potentially important intra-household dynamics. We analysed self-reported consumption relationships between children and adults, and between children of different ages, as well as the associations between intra-household consumption, BMI and sociodemographic characteristics. Design: A cross-sectional analysis …

Escaping the Red Queen: Health as a corporate food marketing strategy
Public health advocates highlight the role of corporate actors and food marketing in shaping diets and health. This study analyses insider-oriented communications in food industry magazines in the UK to analyse actions and narratives related to health and nutrition, providing insights into relatively overlooked areas of marketing strategy including inter-firm dynamics. From a sample of four specialized food industry magazines covering the main in…
Media representations of opposition to the ‘junk food advertising ban’ on the Transport for London (TfL) network: A thematic content analysis of UK news and trade press
The discursive tactics used in media sources to argue against the ban draw on frames widely used by unhealthy commodities industries in response to structural public health interventions. Our analyses highlight the need for interventions to be framed in ways that can pre-emptively counter common criticisms
Changes in take-home aerated soft drink purchases in urban India after the implementation of Goods and Services Tax (GST): An interrupted time series analysis
In India, a country currently with low aerated drink consumption, the implementation of GST was not associated with a reduction in aerated drink purchase in urban settings. Due to the lack of accurate and sufficiently detailed price data, it is not possible to say whether this finding is driven by prices not changing sufficiently. Furthermore, the impact of GST reform on industry practice (reformulation, marketing) and individual behaviour choice…

Reducing consumption of unhealthy foods and beverages through banning price promotions: What is the evidence and will it work
Objective: Increasing prevalence of overweight and obese people in England has led policymakers to consider regulating the use of price promotions on foods high in fat, sugar and salt content. In January 2019, the government opened a consultation programme for a policy proposal that significantly restricts the use of price promotions that can induce consumers to buy higher volumes of unhealthy foods and beverages. These proposed policies are the …

Effect of increasing the price of sugar-sweetened beverages on alcoholic beverage purchases: An economic analysis of sales data
BACKGROUND: Taxing soft-drinks may reduce their purchase, but assessing the impact on health demands wider consideration on alternative beverage choices. Effects on alcoholic drinks are of particular concern, as many contain similar or greater amounts of sugar than soft-drinks and have additional health harms. Changes in consumption of alcoholic drinks may reinforce or negate the intended effect of price changes for soft-drinks. METHODS: A partia…

How much priority is given to nutrition and health in the EU Common Agricultural Policy
Agriculture in the European Union (EU) is strongly influenced by the Common Agricultural Policy (CAP). There have been repeated calls for CAP to address nutrition-related health, particularly obesity and non-communicable disease (NCD) in the EU. However, aligning agricultural policy such as CAP with nutrition is complex, not least because the aims of agricultural policy are predominantly economic, presenting a challenge for developing coherence b…

BACKGROUND: This study evaluates changes in sales of non-alcoholic beverages in Jamie's Italian, a national chain of commercial restaurants in the UK, following the introduction of a £0.10 per-beverage levy on sugar-sweetened beverages (SSBs) and supporting activity including beverage menu redesign, new products and establishment of a children's health fund from levy proceeds. METHODS: We used an interrupted time series design to quantify changes…
Impact of the Irish smoking ban on sales in bars using a large business-level data set from 1999 to 2007
The results indicate that although some bars saw positive effects and some negative, the overall impact of the smoking ban on the value of sales in bars was negligible. These findings provide further supporting evidence that comprehensive smoke-free workplace legislation does not harm hospitality businesses while having positive health effects
