How to promote healthy eating in preschool children: Evidence from an associative conditioning procedure with non-food stimuli

How characters on packaging influence children's choice of a healthy beverage

The present research explores how the use of characters on the packaging of beverages influences children's consumption choices between healthy and less healthy products. Two controlled experiments with a total of 180 children aged between 5 and 11 years old tested how a packaging with character influenced children's choice between a hedonic (apple juice) and a utilitarian product (water). Packaging displaying a character proves particularly effective to influence children behavior, especially when the character is known by the children. Results show that children preferred water over apple juice when the packaging of the water bottle displayed a character, leading to increased water consumption and, consequently, reduced sugar intake.

The policy and practice of establishing healthy eating in preschool children in the Republic of Srpska, Bosnia and Herzegovina: a qualitative study

BACKGROUND

Healthy eating in preschools is a very important but challenging goal that can benefit from an adequate institutional and system approach. Five years ago, the Ministry of Education and Culture in the Republic of Srpska, Bosnia and Herzegovina, adopted a policy for healthy eating in preschools in the form of a rulebook and standards, whose use was not mandatory. The aim of this research was to determine the practices, perceptions, and experiences of preschool personnel related to the implementation of the abovementioned rulebook and standards.

METHODS

We applied a qualitative research method and conducted six focus groups: three with teachers (n = 37) and three with managers in preschools (n = 19). The qualitative data were analyzed according to the Framework Method.

RESULTS

We found that the practice of healthy eating in public preschool settings involves a certain number of facilitators and ongoing challenges. While there are no doubts that the existing rulebook and standards are facilitating efforts in establishing healthy eating in preschools, their implementation has not been an easy-going process, and they have encountered resistance that has appeared at several levels. The participants perceived cookers as resistant and "old-fashioned" in preparing meals, which was found to be a significant challenge that requires education training and ongoing supervision with support. Experiences with limited financial resources and rigid public procurement procedures make it difficult to obtain desired food items. All the participants agreed that long-term commitment is needed to achieve the full implementation of policy recommendations, together with tripartite and convergent education programs for personnel, parents, and children.

CONCLUSION

Promoting proper nutrition in preschools requires a holistic approach that addresses both feasibility and attitudes toward policies, continuous education for staff, creative strategies for implementing new eating habits, and overcoming financial challenges. Collaboration with parents and community stakeholders is crucial in creating a supportive environment for healthy eating habits in preschool settings.

Evaluative conditioning as a source gut feelings and its potential for behavioral nudging

The theme of limited resources pervades the mental health landscape. Practitioners often lack adequate resources to provide interventions for all who could benefit from them, and potential beneficiaries often lack adequate cognitive, financial, and temporal resources to make use of them. Even under rare conditions of bounty, many intensive interventions show small, fleeting effects. Such a landscape begs a space for behavioral nudges: cheap, easily implementable tweaks to people's decision environments aimed at improving health while preserving autonomy. Although existing nudges can be effective, they have their own limitations. Here we explore the case for Evaluative Conditioning (EC) as a largely overlooked yet potentially effective kind of behavioral nudge that can reap nudges' benefits while addressing some of their limitations.

Interventions based on sensory-hedonic strategies and on nudging to facilitate vegetable and pulses consumption in the school environment

Childhood and adolescence shape lifelong taste preferences and dietary habits, making them crucial periods for promoting healthy and sustainable eating. As students consume up to half of their daily energy intake at school, school interventions can have a significant impact on promoting plant-based diets. Although the benefits of promoting plant-based diets on children's and adolescents' health and environmental sustainability are well established and various studies report promising effects of interventions based on sensory-hedonic strategies and on nudging in promoting vegetables and pulses in schools, a comprehensive collection of those reports is lacking. Therefore, this systematic review aims to collect published literature on the above interventions in schools that focus on promoting the consumption of vegetables and pulses to children and adolescents. Three databases-PubMed, Scopus, and Web of Science-were searched over all years until March 2022 using pre-specified terms. From the 10.488 studies identified, a total of 57 studies reporting sensory-hedonic (e.g., manipulating food sensory properties or their hedonic value) or nudging (e.g., changing the presentation) interventions targeting children and/or adolescents in schools and aiming at promoting vegetables and/or pulses were included. Overall, interventions based on sensory-hedonic strategies (either enhancing the perception of well-accepted flavor and texture or manipulating their hedonic value) and on nudging (through incentives and prompts) are effective in promoting vegetables and pulses. A gap in the literature was identified for interventions targeting adolescents and promoting pulses. Finally, multicomponent interventions, rather than using one strategy alone, could be more successful.

Exploring possibilities for the development of healthy eating habits in preschool settings: parent's and teacher's perspectives

Adoption of eating habits starts early in life, through interaction with family members and alongside preschool settings that offer context for developing healthy lifestyles among children. The aim of this study was to explore the perceptions and practices of teachers and parents related to the development of healthy eating habits among preschool children. Focus groups were conducted with a total sample of 48 parents and teachers (three focus groups among parents and three among teachers) from 15 kindergartens in the Republic of Srpska, Bosnia, and Herzegovina. All of the mentioned kindergartens are part of the "Nutrition friendly preschool/school initiative", a program aimed at creating and developing settings that support and improve children's health. Focus groups were audiotaped, transcribed verbatim, and analyzed according to the Framework Method. Teachers emphasized that good communication and support from parents are important factors for the development of healthy eating habits. During COVID-19, direct communication with parents was restricted, and mutual activities among teachers, children, and parents were reduced. Lack of knowledge, finance, and time are perceived by parents as main obstacles to the improvement of children's healthy eating habits. All participants in the focus groups agreed that more education and informative material are needed so their skills related to good nutrition can be improved and adopted in a culture-sensitive way. Mutual support, education, and dissemination of informative materials are imposed as particularly important needs by all actors involved in the upbringing of children in order to support the development of children's healthy eating habits.

Parents' food choice for their preschool-aged children: A means-end investigation

BACKGROUND

Despite the growing literature on the importance of parental feeding practices, the factors that influence how parents make decisions regarding the foods they offer to their young children are not fully understood. Means-end theory and its associated methodology known as laddering provide a useful framework for characterizing the relationships between the attributes of a choice option (e.g., a food item), the consequences (i.e., the benefits or costs/risks) associated with those attributes and the personal values (i.e., enduring beliefs) those consequences help reinforce. The present research uses this means-end perspective to enrich our understanding of how parents make food choices for their preschool-aged children.

METHODS

Interviews were conducted with parents (N = 33) of 3- to 5-year-old children to explore the factors underlying parents' decisions regarding the foods they recently offered, prefer to offer and avoid offering to their preschooler. The resulting data were transcribed, content analysed and summarized in a series of summary diagrams known as hierarchical value maps (HVMs).

RESULTS

Study results indicate that although most parents reported trying to make food decisions because they want their child to be healthy, factors such as avoiding fights/battles and low perceived likelihood their child would eat a food may be barriers to offering certain foods.

CONCLUSIONS

Taken together, these study findings enhance our understanding of the range of meanings underlying parents' food choice decisions and suggest opportunities for interventions to improve the quality of foods that parents offer to their children at home.

A framework for application of consumer neuroscience in pro-environmental behavior change interventions

Most consumers are aware that climate change is a growing problem and admit that action is needed. However, research shows that consumers' behavior often does not conform to their value and orientations. This value-behavior gap is due to contextual factors such as price, product design, and social norms as well as individual factors such as personal and hedonic values, environmental beliefs, and the workload capacity an individual can handle. Because of this conflict of interest, consumers have a hard time identifying the true drivers of their behavior, as they are either unaware of or unwilling to acknowledge the processes at play. Therefore, consumer neuroscience methods might provide a valuable tool to uncover the implicit measurements of pro-environmental behavior (PEB). Several studies have already defined neurophysiological differences between green and non-green individuals; however, a behavior change intervention must be developed to motivate PEB among consumers. Motivating behavior with reward or punishment will most likely get users engaged in climate change action via brain structures related to the reward system, such as the amygdala, nucleus accumbens, and (pre)frontal cortex, where the reward information and subsequent affective responses are encoded. The intensity of the reward experience can be increased when the consumer is consciously considering the action to achieve it. This makes goal-directed behavior the potential aim of behavior change interventions. This article provides an extensive review of the neuroscientific evidence for consumer attitude, behavior, and decision-making processes in the light of sustainability incentives for behavior change interventions. Based on this review, we aim to unite the current theories and provide future research directions to exploit the power of affective conditioning and neuroscience methods for promoting PEB engagement.

All I Need Is Two: The Clinical Potential of Adding Evaluative Pairing Procedures to Cognitive Behavioral Therapy for Changing Self-, Body- and Food-Related Evaluations

Pairing procedures are among the most frequently used paradigms for modifying evaluations of target stimuli related to oneself, an object, or a specific situation due to their repeated pairing with evaluative sources, such as positive or negative images or words. Because altered patterns of evaluations can be linked to the emergence and maintenance of disordered cognitions and behaviors, it has been suggested that pairing procedures may provide a simple yet effective means of complementing more complex intervention approaches, such as cognitive behavioral therapy (CBT). Here, we summarize recent studies that explored the clinical potential of pairing procedures for improving self-esteem, body satisfaction, and food and consumption preferences. While no study has yet combined pairing procedures with CBT, there are several successful examples of pairing procedures in clinically relevant domains and clinical populations. We discuss potential sources of heterogeneity among findings, provide methodological recommendations, and conclude that pairing procedures may bear clinical potential as an add-on to classical psychotherapy.
