The purpose of this scoping review was to summarise the general results of the Chilean Food Law implementation to help to understand how this policy has changed consumer's behaviour.

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews (PRISMA-ScR) guidelines were followed. Five databases were searched for studies published from January 2015 to February 2020 evaluating the Chilean population's perception, behaviour and purchasing habits of processed foods.

The results showed that consumers support the implementation of a front-of-package warning label (FOPWL) and thought it a good strategy to help make healthier food choices for themselves. However, even with a positive perception about these products, the intention-to-change the purchase of unhealthy food occurred only for sugar-sweetened beverages. Meanwhile, children did not stop eating foods that had a FOPWL, although the mothers' perception was that the presence of FOPWLs could be important to differentiate unhealthy from healthy products. The availability of products with FOPWLs at schools decreased, indicating that the law was being complied with and that the child-directed marketing strategy showed a reduction after the first phase of implementation.

This evidence will guide other countries about in understanding and improving this policy.

This is the first study to gather research available in international databases that evaluated the results of the Chilean Law on the advertising of children's food and the perception, purchase intention, reformulation of products and consumption behaviour of the Chilean population.

This paper aims to outline the historic development of advertising regulation that governs food advertising to children in Australia. Through reviewing primary and secondary literature, such as government reports and research, this paper examines the influence of various regulatory policies that limit children’s exposure to food and beverage marketing on practices across television (TV), branded websites and Facebook pages.

This paper reviews studies performed by the food industry and public health researchers and reviews of the evidence by government and non-government agencies from the early 19th century until the present day. Also included are several other research studies that evaluate the effects of self-regulation on Australian TV food advertising.

The government, public health and the food industry have attempted to respond to the rapid changes within the advertising, marketing and media industries by developing and reviewing advertising codes. However, self-regulation is failing to protect Australian children from exposure to unhealthy food advertising.

The findings could aid the food and beverage industry, and the self-regulatory system, to promote comprehensive and achievable solutions to the growing obesity rates in Australia by introducing new standards that keep pace with expanded forms of marketing communication.

This study adds to the research on the history of regulation of food advertising to children in Australia by offering insights into the government, public health and food industry’s attempts to respond to the rapid changes within the advertising, marketing and media industries by developing and reviewing advertising codes.

This paper delves into evaluating the effectiveness of warning messages as a deterrent against excessive fat consumption. It examines how consumers perceive the fat content of food products when presented with two distinct label types: (1) a textual warning, providing succinct information about the fat content, and (2) a pictorial warning, offering a visual representation that immediately signifies the fat content.

Two quantitative studies were carried out. Study 1 employed a questionnaire to evaluate the efficacy of textual and pictorial warning messages on high- and low-fat food products. Similarly, Study 2 replicated this comparison while incorporating a neuromarketing instrument to gauge participants’ cerebral reactions.

Results indicate that pictorial warnings on high-fat foods significantly deter consumers’ purchasing intentions. Notably, these pictorial warnings stimulate the left prefrontal area of the cerebral cortex, inducing negative emotions in consumers and driving them away from high-fat food items.

While the influence of images over text in shaping consumer decisions is well understood in marketing, this study accentuates the underlying mechanism of such an impact through the elicitation of negative emotions. By understanding this emotional pathway, the paper presents fresh academic and managerial perspectives, underscoring the potency of pictorial warnings in guiding consumers towards healthier food choices.

1. Textual warnings do not seem to discourage high-fat product consumption.

2. A pictorial warning represents the fat content of an equivalent product.

3. Pictorial warnings decrease the intention to purchase a high-fat product.

4. Pictorial warnings determine an increase in negative emotions.

This study aims to examine the effects of front-of-package (FoP) labels on the healthy evaluation of Peruvian consumers. This relationship was examined in cases where snacks were healthy and unhealthy. In addition, the study included the role of three consumer purchase objectives (i.e. hedonic, healthy and weight loss) and two types of consumers (high and low use of labelling) in the healthy evaluation.

The sample consisted of 628 Peruvian youngsters aged between 16 and 24 years who frequently consume processed food. The research panel “QueOpinas” oversaw the recruitment of the participants through social media and television. Four types of FoP labels were studied in depth: Nutritional Warnings, Monochrome Guideline Daily Amount (GDA), Polychrome Guideline Daily Amount (GDA-Semaphore) and Traffic Light Labelling. A paired sample t-test and MANOVA were performed to evaluate the research objectives.

The GDA FoP label was found to be insufficient to promote a healthy evaluation. In contrast, the Nutritional Warnings and GDA-Semaphore and Traffic Light FoP labels had a significant and positive effect on the healthy evaluation of the snacks at a 95% confidence level. However, a comparative analysis of the labels revealed that some can be more efficient than others in promoting healthy purchase decisions. For the nutritional warnings (NWs) and traffic light FoP labels, the results revealed that consumers better distinguish unhealthy and healthy cereal bars when these products display traffic light labels.

This research topic has not been investigated in Peru and relevant research in this region is still incipient. In addition, the findings are important for policymakers as the findings will be able to implement specific labelling systems that will help consumers make healthier choices and support the debate about the effectiveness of the main FoP systems.

Building on the social marketing theory, this study aims to examine the relationship between family units and obesity in Nigeria; and the social marketing interventions used to reduce and prevent obesity in the Nigerian society.

This study adopted a semi-structured interview research design with 42 obese individuals in Nigeria.

The study findings show that the family unit an individual grows up in influences their consumption behaviour, which drives their obesity. The findings reveal that obese Nigerian citizens are willing to live a healthier lifestyle due to the direct and indirect medical costs associated with obesity. Furthermore, the findings disclose the social marketing interventions – local celebrity endorsements, healthy lifestyle promotions, reduced gym membership and affordable access to healthy foods and services – used to prevent and reduce the rising obesity rates in the Nigerian society.

The findings have important theoretical implication given the focus on consumption behaviour and obesity.

The study findings provide an avenue to guide government officials, policymakers and social marketers in shaping their public policy and social marketing interventions to encourage healthier consumption and lifestyle behaviours among families and individuals in the Nigerian society.

To the best of the authors’ knowledge, this is the first research study to investigate how family units in the emerging market of sub-Saharan Africa drive obesity and the social marketing interventions used to reduce and prevent obesity. Theoretical and practical implications are discussed.

This study aims to examine consumers' purchasing and consumption behavior regarding big data embedded in packaged food post-Covid-19. The second purpose is to determine whether consumer purchasing behavior varies depending on the variety and volume of big data on food packages.

Semi-structured interviews were conducted to investigate consumer sentiment regarding big embedded data in packaged foods during purchasing. Based on samples from packaged foods sold in international chain stores, interview data collected from 24 participants were subjected to systematic analytical procedures.

The results revealed that before Covid-19, consumers had positive thoughts about the expiration date, brand, and product contents but did not care much about other data. At the same time, post-Covid-19, there were changes in their attitudes and behaviors on this issue. Post-Covid-19, it has been observed that consumers have positive attitudes and behaviors toward human health and food safety issues regarding unprocessed big data in packaged foods.

This study provides a different perspective on consumer purchasing behavior through big data on packaged foods post-Covid-19. Embedded information in packaged foods provides important data regarding consumer purchasing behavior. As a powerful source of consumer sentiment, this data also provides a reference for consumer purchasing decisions.

Nutrition labels provide a cost-effective method of conveying nutrition information to consumers. This study aimed to assess the use of nutrition facts panels, knowledge of traffic light labelling (TLL) and perceived healthiness of food items using TLL among consumers.

A web-based cross-sectional study was conducted among adults in the United Arab Emirates (UAE) (n = 1,322). TLL knowledge score was derived for each participant. Conjoint analysis was used to calculate the utilities and relative importance of the perceived healthiness scores for four attributes (fat, saturated fat, total sugar, salt) at the aggregate level.

Participants had a positive attitude towards TLL but were less familiar with TLL than the nutrition facts panel (47.4 vs 85.8%). The mean TLL knowledge score was 3.6 out of 7 (51.6%). Younger age, higher education, higher income, and health-related qualifications were associated with higher scores. Conjoint analysis showed that participants tend to choose products with greener labels, especially for sugars (80.1%) and avoid red labels for fats. Sugars had the highest percentage value of relative importance compared to the other attributes (27.1%).

The study outcomes offer valuable insights into the extent of consumer awareness, comprehension and utilization of nutrition facts panels in the UAE. These findings contribute essential knowledge for a deeper understanding of the impact of nutrition labels on consumer behaviour and decision-making in the region.

Front-of-pack nutritional labels have been extensively studied to support consumers in making healthier and more informed food choices. However, existing research has gathered conflicting evidence about which category of label, nutrient-specific or summary labels, is more effective. As a result, the European Union has postponed its decision on selecting a unified label to collect additional information. This study specifically focusses on individuals with noncommunicable diseases, an overlooked yet relevant segment of consumers who can significantly benefit from the proper use of nutritional labels in their self-care.

In a sequence of three studies grounded in the front-of-pack acceptance model and focussing on customers with specific noncommunicable diseases, the authors examined the different effects of the NutrInform Battery and Nutri-Score on food acceptance and portion selection. This research involved the use of structural equation modelling and ANOVA and was conducted with a cumulative sample of 2,942 EU adults, residing in countries with or without previous exposure to nutritional labels.

The results suggest that among individuals with noncommunicable diseases, nutrient-specific labels are perceived as more useful and easier to use. They also generate a better attitude towards the usage of nutritional labels and are more effective in nudging those consumers towards a proper selection of portions.

The results provide valuable insights into how front-of-pack nutritional labels can impact the food choices of individuals with noncommunicable diseases and have implications for public health policies.

Investigation of the effects of NutrInform Battery and Nutri-Score on consumers with noncommunicable diseases, an area currently under-researched.

This study aims to investigate the food choice motivations and some healthy food intake among Ardabil adults with different socioeconomic status.

The analysis is based on a focus group study conducted in September 2018. Self-assessed other food choice motivations, healthy food intake and socioeconomic status were reported in questionnaires. The study data were analyzed by one-way ANOVA test and χ² test in groups of study.

Price was a primary motivation of food choice for low-level socioeconomic status persons. The wealthiest people total vegetable consumption was 3.59Â ± 0.004 serving/day, whereas the total vegetable consumption of poorest participants was significantly less than them (p = 0.012). Of the socioeconomics category 1 (SEC1) group participants, 82 per cent said that they consider food price when they were purchasing for their households, while only 28 per cent of SEC4 group said that they consider food prices when food choosing. Only 1 per cent of this group participants pay attention to food label when they choose foods.

This is the first study that investigated the food choice motivations in Ardabil adults. The results indicated that food price is the most critical food choice motivation. Based on this study results, the food policymaker can change people food security and food choices with some programs like as healthy food subsidies and unhealthy food taxes.

This chapter combines a global value chain methodology with the case of the development of the farmed Atlantic salmon industry in Chile to inform discussions regarding the globalization of economy and society. The research documents the shifting structure of the value chain from the north to the south as Chile replaced northern Europe as the locus of production and the major world supplier of farmed Atlantic salmon. Farmed salmon was supported by the Chilean state as part of its export-oriented industrialization model that attracted foreign direct investment (FDI) from northern TNCs. Chile's low costs of production combined with growing environmental problems in the north and global retailers' demand for large quantities of low-cost product resulted in the restructuring of the farmed Atlantic-salmon value chain as northern capital sourced the south as a lucrative production platform to service northern consumers. A detailed investigation of the rise in dominance of the firm Marine Harvest is provided to illustrate the process of industry concentration the Chilean farmed-salmon industry. This model has generated a legitimation crisis related to environmental degradation and labor abuses resulting in social movement organization both nationally and internationally. The chapter concludes with a discussion of the implications of the Wal-Mart Effect on the agrifood industry in particular and in the farmed-salmon industry in particular.
