Research on Influencing Factors of Food Choice and Food Consumption.

Nowadays, most consumers are well aware of what makes up a healthy and sustainable diet [...].

Intervention strategies to promote healthy and sustainable food choices among parents with lower and higher socioeconomic status.

BACKGROUND: A global shift towards more healthy and sustainable diets is necessary for the prevention of obesity and chronic diseases, as well as for the growing pressure on our ecosystems. Given that parents are important actors in affecting dietary behaviors of their children, developing intervention strategies targeting families and their practices is promising to reach positive behavior change among children. Also, it is important to tailor these interventions to the needs of parents with different socioeconomic statuses (SES), given that health inequalities continue to grow. This study aims to investigate perspectives of lower and higher SES parents on the usability and acceptability of various innovative intervention strategies. METHODS: Fourteen focus groups and four individual interviews (n = 78, nlowerSES = 17; nhigherSES = 61) were conducted in Belgium. A semi-structured interview guide was used to facilitate the discussions. The interviews were recorded, transcribed, and analyzed via thematic content analysis using NVivo. RESULTS: To encourage healthy and sustainable food choices, interventions via online food shopping platforms and nudging strategies in grocery stores were mostly cited by higher SES parents, but these were less applicable for lower SES parents as they buy less online and mainly consider the price of products. Mobile applications that provide inspiration for healthy and sustainable recipes and easily accessible shopping lists received moderate support among lower and higher SES parents. Furthermore, both lower and higher SES parents showed interest in meal boxes delivered at home, but lower SES parents have not yet tried such meal boxes because of their higher prices. Still, both groups of SES parents mentioned many advantages of these meal boxes, such as the convenience and time-saving component, as well as the cooking inspiration aspect. CONCLUSION: Our study reveals the preferences of lower and higher SES parents for practical intervention strategies, providing insight in what features these strategies should have to be acceptable and useful. Hence, the findings can inform the development of a tailored family-based intervention strategy to improve parental food choices in favor of increased health and sustainability.

Determinants of healthy and sustainable food choices in parents with a higher and lower socioeconomic status: A qualitative study.

Establishing healthy and sustainable dietary habits in childhood is necessary for the prevention of obesity and chronic diseases, as well as for the growing pressure on our ecosystems. Considering that parents are the most important actors in affecting dietary behaviors of their children, and that there is a social gradient for obesity, this study aims to investigate differences in determinants of both healthy and sustainable food choices among parents with a higher and lower socioeconomic status (SES). Fifteen focus groups and four individual interviews (n = 78) with parents of children aged 6 to 12 were conducted in Belgium. A semi-structured interview guide based on a socioecological model was used. The interviews were recorded, transcribed and thematic content analysis was performed using NVivo 1.0. Findings indicate some differences in determinants of healthy and sustainable food choices among higher and lower SES parents. Generally, higher SES parents reported more barriers for sustainable than for healthy food choices. They showed more positive attitudes towards healthy than sustainable food choices, and reported low knowledge and self-efficacy to make sustainable food choices, while a lack of time was a barrier to cook both healthy and sustainable meals. Lower SES parents, like higher SES parents, showed more positive attitudes towards healthy food choices. They reported high prices and a lack of inspiration and skills as barriers for both food choices, while also being influenced by their cultural backgrounds. For both SES types of parents, children had a strong influence on their healthy and sustainable food choices. The findings suggest socioeconomic differences in determinants of healthy and sustainable food choices. Hence, these differences should be taken into account when developing intervention strategies to improve food choices in parents.

Food Media and Dietary Behavior in a Belgian Adult Sample: How Obtaining Information From Food Media Sources Associates With Dietary Behavior.

Objective: We aim to relate Flemish adults' main food information sources (e.g., celebrity chefs, experts) with their dietary behavior. Methods: A cross-sectional online survey among 1115 Flemish adults who regularly cook, measured the food information sources the respondents used to obtain recipes, their dietary intake and dietary restrictions. Ordinal and logistic regression were used to investigate the relation between food media, dietary intake and dietary restrictions. Results: Celebrity chefs were mentioned most often (37%) as main food information source, followed by family and acquaintances (21%) and lifestyle gurus (12%). Using lifestyle gurus as a source of dietary information is associated with more dietary restrictions and a higher intake frequency of plant-based food groups, whereas using celebrity chefs or experts is associated with a different (but less unequivocal vegetarian or healthy) dietary intake. Conclusion: Media icons like lifestyle gurus and celebrity chefs appear to be among people's main sources of food information. There is a significant association between using them as a source of food information and dietary behavior. Further research on the influence of media on diet is required.

Take a Bite! The Effect of Bitten Food in Pictures on Product Attitudes, Purchase Intentions, and Willingness to Pay.

Food pictures in advertisements, on packages, and on social media often display food with a bite in it. We investigated the effect of pictures of food with a bite (vs. no bite) on product attitudes, purchase intentions, and willingness to pay. In two online experimental studies we tested this effect for both pictures without context, as well as pictures in an advertisement. We also investigated two theories that could lead to opposite effects: consumer contamination and embodied mental simulation. We found that a picture of food with a bite (vs. no bite) resulted in lower purchase intentions, and that this effect was mediated by disgust (i.e., consumer contamination). Furthermore, we found an interaction effect of picture type (i.e., bite vs. no bite) and context (i.e., no context vs. advertisement) on purchase intentions: the effect of picture type on purchase intentions was attenuated when the picture appeared in an advertisement (vs. when the picture is shown without context). We found similar effects on product attitudes and willingness to pay. Lastly, a picture of food with a bite (vs. no bite) had no effect on embodied mental simulation. Field practitioners are advised to take caution when using pictures of bitten food as this may lead to unfavorable consumer responses because of a feeling if disgust.

Animals Like Us: Leveraging the Negativity Bias in Anthropomorphism to Reduce Beef Consumption.

Our current work contributes to the literature of meat consumption reduction. Capitalizing on the inherent humanizing characteristic of anthropomorphism coupled with leveraging negativity bias, we created a novel approach to reduce meat-eating intention. Using on-pack product stickers, we compare an anthropomorphic message stressing the capacity to experience pain with two other anthropomorphic messages that have been used before in the literature (intelligence and pro-social behavior of animals). We find that an on-pack pain anthropomorphic sticker reduces purchase intentions of the meat product and intention to consume meat in general and is more effective than stickers displaying pro-social or intelligence messages. We also show that the pain message's negative impact on purchase intention is serially mediated by anticipatory guilt and attitude towards meat. In addition, we show that the differential effectiveness of the anthropomorphic messages can be explained by the negativity bias. That is, when the pro-social and intelligence messages were formulated in a negative way (as is pain), all three messages were equally effective at reducing intention to purchase meat and increase intention to reduce meat consumption.

Environmentally Sustainable Food Consumption: A Review and Research Agenda From a Goal-Directed Perspective.

The challenge of convincing people to change their eating habits toward more environmentally sustainable food consumption (ESFC) patterns is becoming increasingly pressing. Food preferences, choices and eating habits are notoriously hard to change as they are a central aspect of people's lifestyles and their socio-cultural environment. Many people already hold positive attitudes toward sustainable food, but the notable gap between favorable attitudes and actual purchase and consumption of more sustainable food products remains to be bridged. The current work aims to (1) present a comprehensive theoretical framework for future research on ESFC, and (2) highlight behavioral solutions for environmental challenges in the food domain from an interdisciplinary perspective. First, starting from the premise that food consumption is deliberately or unintentionally directed at attaining goals, a goal-directed framework for understanding and influencing ESFC is built. To engage in goal-directed behavior, people typically go through a series of sequential steps. The proposed theoretical framework makes explicit the sequential steps or hurdles that need to be taken for consumers to engage in ESFC. Consumers need to positively value the environment, discern a discrepancy between the desired versus the actual state of the environment, opt for action to reduce the experienced discrepancy, intend to engage in behavior that is expected to bring them closer to the desired end state, and act in accordance with their intention. Second, a critical review of the literature on mechanisms that underlie and explain ESFC (or the lack thereof) in high-income countries is presented and integrated into the goal-directed framework. This contribution thus combines a top-down conceptualization with a bottom-up literature review; it identifies and discusses factors that might hold people back from ESFC and interventions that might promote ESFC; and it reveals knowledge gaps as well as insights on how to encourage both short- and long-term ESFC by confronting extant literature with the theoretical framework. Altogether, the analysis yields a set of 33 future research questions in the interdisciplinary food domain that deserve to be addressed with the aim of fostering ESFC in the short and long term.

'My lips are sealed' - The impact of package resealability on the consumption of tempting foods.

Resealable packages are nowadays omnipresent on store shelves. While the main advantage of the resealability feature is its ability to reclose the package in order to extend the shelf life of the food product inside, the present research's aim is to assess whether this advantage also has implications for palatable, energy-dense food consumption. Two studies provide intentional as well as behavioral evidence for the claim that consumers are better able to self-regulate their consumption and thus eat less in one occasion when a palatable, energy-dense food product is offered in a resealable (vs. unresealable) package. A third study investigates the effect of package resealability across multiple consumption occasions and reveals that the resealability feature limits the volume consumed on each occasion (conditional on consumption incidence) while it does not accelerate consumption frequency, resulting in a lower total consumed volume of palatable, energy-dense snacks over a six-day period. This research offers actionable insights for consumer welfare and public health care and aids manufacturers in delineating optimal food packaging strategies.

Cross-national investigation of the drivers of obesity: Re-assessment of past findings and avenues for the future.

In this paper we question whether prior cross-national differences in food attitudes still exist and if so, to what extent. Due to societal evolutions such as sedentarism and globalization, international variations in food attitudes may not be as pronounced as currently believed. A cross-sectional web-based survey was carried out in the United States, the United Kingdom, France and Belgium. A total of 2167 respondents (52% women; mean age = 39.0 years, SD = 11.4) participated. To successfully combat obesity, a joint approach focusing on food choice and physical activity is required; therefore we included behavioral measures by means of choice tasks for these two important drivers. Further, the extent to which respondents subscribe to the unhealthy = tasty intuition, together with health and taste interest were investigated. Socio-demographic information and self-reported heights and weights were also incorporated. Logistic regressions were fitted with weight status as the dependent variable and the attitudinal and behavioral measures as independent variables. Our findings indicate that having a higher interest in healthy eating decreases the chance of being overweight (odds = 0.88) and believing that unhealthy food is tasty significantly increases the chance of being obese by 1.18 times. Overall, we find that food attitudes have largely converged across the countries we investigated.

To squeeze or not to squeeze: How squeeze tubes affect consumers' serving sizes.

Squeeze tubes increasingly complement traditional packaging. But, would squeeze tubes - besides offering ease of use - also affect consumers' serving sizes? And if so, in what way? To answer these questions, we contrast the motor fluency hypothesis (i.e., bodily movements affect judgments) with the consumption monitoring hypothesis (i.e., paying attention to quantities eaten affects consumption). Two studies reveal that consumers use less of a product when it comes in a squeeze tube versus a traditional container, providing initial evidence for the consumption monitoring hypothesis. A third study also provides evidence that the ease of consumption monitoring drives the squeeze tube effect, which is more prominent for unrestrained eaters. These findings have important implications for consumers, public policy makers, and product manufacturers.

The stability of individual response styles.

Modeling capabilities for longitudinal data have progressed considerably, but questions remain on the extent to which method bias may negatively affect the validity of longitudinal survey data. The current study addresses the stability of individual response styles. We set up a longitudinal data collection in which the same respondents filled out 2 online questionnaires with nonoverlapping sets of heterogeneous items. Between data collections, there was a 1-year time gap. We simultaneously modeled 4 response styles that capture the major directional biases in questionnaire responses: acquiescence, disacquiescence, midpoint, and extreme response style. Drawing from latent state-trait theory, we specified a 2nd-order factor model with time-invariant and time-specific response style factors and a specifically designed covariance structure for the residual terms. The results indicate that response styles have an important stable component, a small part of which can be explained by demographics. The meaning and implications of these findings are discussed.

Healthy or unhealthy slogans: that's the question...

An experiment was conducted to examine the effect on adolescents of different health appeals (healthy versus unhealthy) in ads for healthy and unhealthy perceived foods. The results did not reveal a main effect of product or slogan, but indicated a significant interaction effect between slogan and product. The healthy slogan only led to significantly more positive attitudes and purchase intentions when it promoted a healthy food product. An unhealthy food product received better results in combination with an unhealthy slogan than with a healthy one. This indicates that adolescents react better to ads in which the health appeal is congruent with the health perception of the product. Moreover, we took into account gender and health concern as potential moderators in the relationship between slogan and ad responses. Gender did not lead to different responses to healthy or unhealthy food ads, whereas health concern did interact significantly with the slogan type. Highly concerned adolescents responded more favorably to a healthy slogan in terms of attitudes. A necessary first step seems to be making adolescents more health conscious. A following step is to reinforce their positive attitudes toward healthy foods and turn these into real behavior.

Need for closure and youths' leisure time preferences.

The Need for Closure is an individual characteristic which may help explain individual differences in engagement in leisure activities. Both a leisure engagement inventory and a validated Dutch version of the Need for Closure Scale were administered to a convenient sample of 1,035 young adults ages 15 to 24 years of whom 552 were female. Leisure engagement was hypothesized to differ for groups differing in Need for Closure. More specifically, youngsters who score high (versus low) on Need for Closure engaged more in structured, cognitively effortless, and predictable leisure activities like shopping for fun and going to the cinema, while young adults scoring low (versus high) on Need for Closure more often participated in unstructured, unpredictable, cognitively effortful or challenging leisure activities like going to a party, a pub, or a pop concert, idly lazing away, visiting or hosting friends, attending an evening class and playing computer games.

Developing a Short Affect Intensity Scale.

The purpose of this study was to construct a brief version of the 40-item Affect Intensity Measure. Since the assumed one-dimensionality of the scale has been criticized lately, special attention was paid to the factor structure of the full and the brief scales. The scales were tested in three different samples: 510 Belgian citizens representative of the Belgian population, and 204 and 166 students of the University of Antwerp. The Short Affect Intensity Scale has 20 items. Mean scores on the original Affect Intensity Measure were 3.68, 3.67, and 3.67 for the three samples, respectively, while for the Short Affect Intensity Scale the following respective mean scores were registered: 3.76, 3.78, and 3.75. Correlations between the original and brief scales were .94, .93, and .93 for the three samples, respectively. Three factors underlie the Short Affect Intensity Scale: Positive Intensity, Negative Affectivity, and Serenity. Furthermore, the scores for the Short Affect Intensity Scale suggest it is reliable and valid.
