To analyse food advertised on an online food delivery (OFD) platform during 16 weeks of the COVID-19 pandemic in Brazil.
Design:
Longitudinal study. We randomly selected foods advertised on the OFD app’s home page, classifying the food items into: water; natural juices and smoothies; vegetables; fruits; traditional meals and pasta; ultra-processed beverages; ice cream, candies, and salty packaged snacks; sandwiches; savoury snacks; and pizza. We also registered the marketing strategies used to promote the food items, such as photos, discounts, ‘combo deals’, and messages on healthiness, value for the money, tastiness, and pleasure.
Setting:
Belo Horizonte, Minas Gerais, Brazil.
Participants:
1593 food items.
Results:
In general, the OFD platform most commonly promoted traditional meals and pasta, ultra-processed beverages, and sandwiches – these food groups were offered 20–25 % of the time during the 16 weeks. There were no promotions for water during the whole period, and the least common promotions were those for natural juices and smoothies, vegetables, and fruits (< 5 %). The most common food promotion strategies were photos (> 80 %) and discounts (> 95 %), while approximately 30 % of the offers featured combo deals. Messages on tastiness, pleasure and value for the money varied from 15 % to 40 %.
Conclusion:
Although the OFD platform offered traditional meals and pasta, most of the foods and beverages advertised were unhealthy and promoted with persuasive strategies. This finding highlights a growing public health concern: an increase in unhealthy eating patterns during the pandemic.
To determine whether the ‘Read for Nutrition’ programme would increase liking and consumption of broccoli (a target vegetable) in preschool children and test acceptability and practicality of the programme.
Design:
Pilot pre-post intervention study, where childcare teachers received training and coaching followed by reading the book ‘Monsters Don’t Eat Broccoli’ multiple times with the children during a three-week intervention.
Setting:
Five classrooms of Educare, Lincoln, Nebraska in 2018.
Participants:
Sixty-nine (11 to 16 children per classroom) preschool-aged children and sixteen teachers (minimum, three per classroom).
Results:
Average total consumption of broccoli increased 35 % (0·14 ounces or 0·05th cup) after the ‘Read for Nutrition’ programme (t = 2·66; P = 0·01; 95 % CIs (0·035, 0·246)) for all children. Proportional consumption increased for children who received ≥ five exposures to the book (t46 = 2·77; P = 0·008). Exposures to the book predicted proportional consumption (β = 0·365; P = 0·002). Liking of broccoli increased (W69 = 2·2, P = 0·03) as well. Teachers rated the programme as acceptable, practical and enjoyable to children and to themselves.
Conclusions:
Programmes such as ‘Read for Nutrition’ have the potential to improve children’s vegetable liking and consumption in early care and education settings with only book readings and no exposure to a real vegetable.
With the phase-out of the polio campaigns, Burkina Faso has developed a new strategy for routine community-based vitamin A supplementation (VAS) by institutionalising community-based health workers (CBHW) to sustain the gain of two decades of successful programming. Formative research was conducted soon after the strategy was introduced to solicit feedback on the acceptability of the new approach by the implementing actors while identifying the main implementation challenges for improving its effectiveness and sustainability.
Design:
This qualitative study was conducted in 2018 through (i) document review, (ii) individual interviews with key informants at the central, regional and district levels, and (iii) focus groups with CBHW and caregivers.
Setting:
Data collection was carried out at six levels of sites covering the entire country and selected based on VAS coverage rates with the community routine. A total of six health districts were selected.
Participants:
We conducted 46 individual interviews with health workers and 20 focus groups with 59 CBHW and 108 caregivers.
Results:
The study showed good acceptability of the strategy by all stakeholders. In the first 2 years of implementation, the national coverage of VAS was maintained at a high level (above 90 %) and there was a reduction in operational costs. The main challenges included delayed CBHW remuneration and weak communication and supervision
Conclusions:
The acceptability of the community-based routine VAS was good and was perceived to have a high potential for sustainability. Addressing identified challenges will allow us to better manage the expectations of community stakeholders and maintain the initial results
To evaluate the feasibility and acceptability of a mobile-based brief intervention (BI), generate preliminary estimates of the impact of the BI and fine-tune the procedures for a definitive randomised controlled trial.
Design:
Parallel three-arm single-blind individually randomised controlled pilot trial. Eligible and consenting participants were randomised to receive mobile-based BI, face-to-face BI and information leaflet.
Setting:
Educational institutions, workplaces and primary care centres.
Participants:
Adult hazardous drinkers.
Results:
Seventy-four participants were randomised into the three trial arms; forty-eight (64·9 %) completed outcome evaluation. There were no significant differences between the three arms on change in any of the drinking outcomes. There were however in two-way comparisons. Face-to-face BI and mobile BI were superior to active control for percent days heavy drinking at follow-up, and mobile BI was superior to active control for mean grams ethanol consumed per week at follow-up.
Conclusion:
The encouraging findings about feasibility and preliminary impact warrant a definitive trial of our intervention and if found to be effective, our intervention could be a potentially scalable first-line response to hazardous drinking in low-resource settings.
The rapid growth in web-based grocery food purchasing has outpaced federal regulatory attention to the online provision of nutrition and allergen information historically required on food product labels. We sought to characterise the extent and variability that online retailers disclose required and regulated information and identify the legal authorities for the federal government to require online food retailers to disclose such information.
Design:
We performed a limited scan of ten products across nine national online retailers and conducted legal research using LexisNexis to analyse federal regulatory agencies’ authorities.
Setting:
USA.
Participants:
N/A.
Results:
The scan of products revealed that required information (Nutrition Facts Panels, ingredient lists, common food allergens and per cent juice for fruit drinks) was present, conspicuous and legible for an average of only 36·5 % of the products surveyed, ranging from 11·4 % for potential allergens to 54·2 % for ingredients lists. More commonly, voluntary nutrition-related claims were prominently and conspicuously displayed (63·5 % across retailers and products). Our legal examination found that the Food and Drug Administration, Federal Trade Commission and United States Department of Agriculture have existing regulatory authority over labelling, online sales and advertising, and Supplemental Nutrition Assistance Programme retailers that can be utilised to address deficiencies in the provision of required information in the online food retail environment.
Conclusions:
Information regularly provided to consumers in conventional settings is not being uniformly provided online. Congress or the federal agencies can require online food retailers disclose required nutrition and allergen information to support health, nutrition, equity and informed consumer decision-making.
To evaluate the impact of the 2017 update to the voluntary Advertising Standards Authority (ASA) code for advertising food on children and young people’s exposure to unhealthy food advertisements on New Zealand television.
Design:
Audience ratings data were analysed for New Zealand children and young people’s television viewing for eight random days prior to (June to August 2015) and following (October to December 2018) the code update, from 06.00 to midnight (864 h). Food advertisements were coded using three nutrient profiling models. The number of children and young people watching television each year was compared.
Setting:
Three free-to-air New Zealand television channels.
Participants:
New Zealand children aged 5–18 years.
Results:
Television viewer numbers decreased over the 3 years (P < 0·0001). The mean rate of unhealthy food advertising on weekdays was 10·4 advertisements/h (2015) and 9·5 advertisements/h (2018). Corresponding rates for weekend days were 8·1 and 7·3 advertisements/h, respectively. The percentage of food advertisements which were for unhealthy foods remained high (63·7 % on weekdays and 65·9 % on weekends) in 2018. The ASA definition of children’s ‘peak viewing time’ (when 25 % of the audience are children) did not correspond to any broadcast times across weekdays and weekend days.
Conclusions:
Between 2015 and 2018, children and young people’s television exposure to unhealthy food advertising decreased. However, almost two-thirds of all food advertisements were still unhealthy, and the updated ASA code excluded the times when the greatest number of children was watching television. Consequently, government regulation and regular monitoring should reflect the evolving food marketing environment.
To identify the regulatory governance factors that lead to food policies achieving improvements in food environment, consumer behaviour and diet-related health outcomes.
Design:
Qualitative comparative analysis (QCA) was used to investigate the relationship between regulatory governance conditions and population nutrition outcomes. The regulatory governance conditions examined entailed: high industry involvement in the policy process, regulatory design, policy instrument design, policy monitoring and enforcement.
Participants:
n 29 policy cases in the policy areas of food reformulation, nutrition labelling, food taxation and food marketing.
Setting:
Policies implemented in thirteen countries.
Results:
Comprehensive monitoring was identified as a necessary regulatory governance condition for food policies to have an impact and was present in 94 % of policy cases that had a positive impact on nutrition outcomes. We identified two sufficient combinations of regulatory governance conditions. The first sufficient combination of conditions comprised an absence of high industry involvement in the policy process, combined with the presence of strict regulatory design, best-practice instrument design, and comprehensive monitoring and enforcement. Ninety-six percent of policy cases with positive impacts on nutrition outcomes displayed this combination. The second sufficient combination of conditions comprised an absensce of high industry involvement in the policy process, best practice instrument design and comprehensive monitoring. Eighty-two percent of policy cases with positive impacts on nutrition outcomes displayed this combination.
Conclusion:
These findings show the importance of regulatory governance on policy outcomes. They suggest a need for more government-led nutrition policy processes and transparent monitoring systems that are independent from industry.
Dietary patterns characterised by high intake of red and processed meat are associated with detrimental health and environmental outcomes. To better understand how Americans consume red and processed meat, this study examined the food groups that are the greatest contributors to red and processed meat intake in US diets.
Design:
Cross-sectional analysis of total red and processed meat, unprocessed red meat and processed meat using data from the National Health and Nutrition Examination Survey (2015–2016 and 2017–2018). Items containing red or processed meat were classified into thirteen mutually exclusive food groups. For highly consumed food groups (≥10 % of meat intake), contribution to meat intake was further assessed by source, sex, income and education.
Setting:
Nationally representative sample of the US population.
Participants:
Teens (aged 12–19 years) and adults (aged ≥20 years) who reported meat consumption (n 8178).
Results:
Meat mixed dishes (18·6 % (95 % CI 16·2, 20·9)), burgers (17·3 % (95 % CI 15·3, 19·3)) and beef excluding ground (17·0 % (95 % CI 13·8, 20·1)) were the top contributors to unprocessed red meat intake. For processed meat, four food groups made up about four-fifths of total intake: cold cuts and cured meats (37·7 % (95 % CI 34·6, 40·8)), sausages and frankfurters (20·3 % (95 % CI 18·6, 22·0)), bacon (14·0 % (95 % CI 12·3, 15·6)) and pizza (10·1 % (95 % CI 8·7, 11·5)). Fast-food restaurants were the top source for burgers and pizza, whereas stores were the top source for all other highly consumed food groups. Few differences were seen in patterns of intake by sociodemographic characteristics.
Conclusions:
No single food group accounts for a majority of meat intake in the USA. Many behaviour change opportunities for healthier, more sustainable substitutions exist.
To compare the nutritional composition of bovine milk and several plant-based drinks with a focus on protein and essential amino acid content and to determine the ratio of essential amino acids to greenhouse gas emission.
Design:
Nutritional information on the label was extracted for semi-skimmed milk, soy, oat, almond, coconut and rice drink from the Innova database between January 2017 and March 2020 for the Netherlands, Belgium, Germany, Spain, Italy and Sweden. Protein and amino acids were measured and carbon footprint was calculated for a selection of Dutch products. Protein quality was determined by calculating the contribution to the WHO essential amino acids requirements.
Setting:
The bovine milk and plant-based drinks market in Netherlands, Belgium, Germany, Spain, Italy and Sweden.
Participants:
Semi-skimmed bovine milk and soy, oat, almond, coconut and rice drink.
Results:
Nutritional label information was collected for 399 products. Milk naturally contains many micronutrients, e.g. vitamin B2, B12 and Ca. Approximately 50 % of the regular plant-based drinks was fortified with Ca, whereas the organic plant-based drinks were mostly unfortified. Protein quantity and quality were highest in milk. Soy drink had the best protein quality to carbon footprint ratio and milk came second.
Conclusions:
The nutrition – climate change balance presented in this study, is in line with previous literature, which shows that semi-skimmed bovine milk and fortified soy drink deserve a place in a sustainable diet.
