Healthy eating interventions conducted in small, local restaurants and hot food takeaways: A systematic review.

Objective: This systematic review investigates the characteristics, effectiveness, and acceptability of interventions to encourage healthier eating in small, independent restaurants and takeaways.

Design: We searched five databases (CENTRAL, Medline, Embase, CINAHL, and Science Citation Index & Social Science Citation Index) in June 2022. Eligible studies had to measure changes in sales, availability, nutritional quality, portion sizes, or dietary intake of interventions targeting customer behaviour or restaurant environments.

Do calorie labels change energy purchased in a simulated online food delivery platform? A multi-arm randomised controlled trial.

Background: As rates of obesity and overweight continue to increase in the UK, calorie labels have been introduced on menus as a policy option to provide information to consumers on the energy content of foods and to enable informed choices. This study tested whether the addition of calorie labels to items in a simulated food delivery platform may reduce the energy content of items selected.

Methods: UK adults (n = 8,780) who used food delivery platforms were asked to use the simulated platform as they would in real life to order a meal for themselves.

The impact of the English calorie labelling policy on the energy content of food offered and purchased in worksite cafeterias: a natural experiment.

Background: On 6 April 2022, legislation came into effect in England requiring calorie labels to be applied to food items on menus of larger food businesses. This study aimed to assess the impact of calorie labelling on (a) food purchased and (b) energy content of menu options in worksite cafeterias.

Methods: Product-level sales data and energy content of available items was obtained from 142 worksite cafeterias from January 2022-October 2022.

Do promotions of healthier or more sustainable foods increase sales? Findings from three natural experiments in UK supermarkets.

Background: Dietary changes are necessary to improve population health and meet environmental sustainability targets. Here we analyse the impact of promotional activities implemented in UK supermarkets on purchases of healthier and more sustainable foods.

Methods: Three natural experiments examined the impact of promotional activities on sales of a) no-added-sugar (NAS) plant-based milk (in 199 stores), b) products promoted during 'Veganuary' (in 96 stores), and c) seasonal fruit (in 100 non-randomised intervention and 100 matched control stores).

The impact of the UK soft drink industry levy on the soft drink marketplace, 2017-2020: An interrupted time series analysis with comparator series.

Background: In April 2018, the UK government implemented a levy on soft drinks importers and manufacturers, tiered according to the amount of sugar in drinks. The stated aim was to encourage manufacturers to reduce sugar and portion sizes. Previous evidence suggests that the policy has been successful in reducing sugar in drinks in the short-term since implementation, but their sustained effects have not been explored.
