Taxing fat versus behavioural interventions
Do promotions of healthier or more sustainable foods increase sales? Findings from three natural experiments in UK supermarkets
During promotional campaigns there was evidence that sales of plant-based products increased, but not seasonal fruits. There was no evidence for any sustained change beyond the intervention period

Nutrition labels and ecolabels can support consumers to make healthier and more sustainable choices, and the former is now widespread. But there is no information on the impact of ecolabels in the presence of nutrition labels. The aims of this study were primarily to examine whether (1) ecolabels are effective at promoting sustainable purchasing behaviour if presented alongside nutrition labels; (2) and secondarily, whether nutrition labels are e…
The impact of price promotions on confectionery and snacks on the energy content of shopping baskets
Overconsumption of foods high in fat, sugars, and salt (HFSS) poses a significant risk to health. The government in England has passed legislation that would limit some price promotions of HFSS foods within supermarkets, but evidence regarding likely impacts of these policies, especially in online settings, is limited. This study aimed to determine whether there were any differences in the energy and nutrient content of shopping baskets after rem…
Changes in health-related lifestyles and food insecurity and its association with quality of life during the Covid-19 lockdown in Malaysia
The unprecedented COVID-19 outbreak and the lockdown measure during the pandemic have caused significant negative changes in health-related lifestyles and affected the QoL of Malaysian adults. Despite the new norms and rules to prevent disease transmission, efforts to maintain a healthy lifestyle and food security among the population must be rolled out to improve the QoL and prevent further adverse mental and physical health outcomes
Testing the effectiveness of ecolabels to reduce the environmental impact of food purchases in worksite cafeterias
1. Introduction Meeting global climate targets will require a marked reduction in environmental impacts caused by dietary patterns (Willett et al., 2019), with several UK supermarkets setting targets to halve the environmental impact of customers' food shopping by 2030 (Lee, 2021). The environmental impacts of different types of foods are highly variable, and variation in impact is also seen for a given food. For example, there is a 50-fold varia…
Optimising swaps to reduce the salt content of food purchases in a virtual online supermarket
BACKGROUND: Offering consumers the opportunity to swap to lower-salt foods while shopping has potential to reduce salt intake. Offering a wider range of alternatives which are much lower in salt could increase the magnitude of salt reduction gained but may interfere with consumers' engagement and willingness to accept swaps. OBJECTIVES: To compare the salt reduction from offering swaps to a similar product but with minimally less salt to offering…
Grocery store interventions to change food purchasing behaviors
Systematic review and meta-analysis of remotely delivered interventions using self-monitoring or tailored feedback to change dietary behavior
Estimating usual intakes mainly affects the micronutrient distribution among infants, toddlers and pre-schoolers from the 2012 Mexican National Health and Nutrition Survey
Objective To compare estimates from one day with usual intake estimates to evaluate how the adjustment for within-person variability affected nutrient intake and adequacy in Mexican children. Design In order to obtain usual nutrient intakes, the National Cancer Institute’s method was used to correct the first 24 h dietary recall collected in the entire sample ( n 2045) with a second 24 h recall collected in a sub-sample ( n 178). We computed esti…
Current patterns of water and beverage consumption among Mexican children and adolescents aged 1–18 years
Objective To evaluate patterns of water consumption from plain water, beverages and foods among Mexican children and adolescents and to compare actual patterns of total daily water intake with the Dietary Reference Intakes (DRI). Design We analysed one 24 h dietary recall from Mexican children and adolescents. We calculated intakes of total daily water and water from foods and from beverages. Actual total water intake per capita was subtracted fr…
Trends In Snacking Among U.S. Children
Nationally representative surveys of food intake in U.S. children show large increases in snacking between the 1989-91 to 1994-98 and 1994-98 to 2003-06 periods. Childhood snacking trends are moving toward three snacks per day, and more than 27 percent of children's daily calories are coming from snacks. The largest increases have been in salty snacks and candy. Desserts and sweetened beverages remain the major sources of calories from snacks.
