Jang R, Lee WS, Moon J. Relationship between Presentation, Attitude, and In-Flight Meal Food Healthiness: Moderating Role of Familiarity. Foods 2024; 13:2111. [PMID: 38998617 PMCID: PMC11241314 DOI: 10.3390/foods13132111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Revised: 06/10/2024] [Accepted: 07/01/2024] [Indexed: 07/14/2024] Open
Abstract
This work focused on the perception of the food healthiness of in-flight meals. This work adopts presentation as the determinant. This work also employs attitude as the consequence of food healthiness. This research also examines the moderating effect of familiarity on the relationship between food presentation and food healthiness. This research used a survey, and survey participants were recruited via a Clickworker platform service. Survey participants were experienced with in-flight meals. The number of observations was 317. Moreover, this research tested the research hypotheses using the Hayes process macro Model 7. The results revealed that food healthiness is positively influenced by presentation and that food healthiness positively affects attitude. Moreover, the results revealed that the type of presentation has a positive influence on attitude. Familiarity was a significant moderating variable for the relationship between food presentation and food healthiness. This work sheds light on the literature by identifying the associations among four attributes of in-flight meals. Additionally, the results of this study could be used as a reference to develop better in-flight meals.

Abstract
This experimental study investigates the effects of several heuristic cues and systematic factors on users' misinformation susceptibility in the context of health news. Specifically, it examines whether author credentials, writing style, and verification check flagging influence participants' intent to follow article behavioral recommendations provided by the article, perceived article credibility, and sharing intent. Findings suggest that users rely only on verification checks (passing/failing) in assessing information credibility. Of the two antecedents to systematic processing, social media self-efficacy moderates the links between verification and participants' susceptibility. Theoretical and practical implications are discussed.

Bayır T, Çam S, Tuna MF. Does knowledge and concern regarding food supplement safety affect the behavioral intention of consumers? An experimental study on the theory of reasoned action. Front Nutr 2024; 10:1305964. [PMID: 38260066 PMCID: PMC10800543 DOI: 10.3389/fnut.2023.1305964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Accepted: 12/19/2023] [Indexed: 01/24/2024] Open
Abstract
In recent years, health crises have led consumers to make more frequent purchases of food supplements. The global food supplement market, which reached $61.20 billion in 2020, is estimated to reach $163.12 billion by 2022 and $350.96 billion by 2032. However, many consumers still have concerns about the safety of food supplements. Within the scope of the research, firstly, the health consciousness (HC) level of food supplement consumers was determined. Secondly, food safety knowledge (FSK) and food safety concerns (FSCs) were measured. Thirdly, consumers' attitudes (ATUs), subjective norms (SNs), and behavioral intentions (BIs) toward food supplements were determined within the scope of the theory of reasoned action. The study used a convenient sampling, and 327 participants were included in the sample population. The data for the analysis was collected using the online survey method in the third quarter of 2023. The relationships between hypothesized items in the structural model were tested using the Smart-PLS. The validity and reliability of the measurement model were evaluated at the start of the structural equation modelling approach using confirmatory factor analysis (CFA). Regression analyses were performed in the structural model phase to evaluate overall fit and suggested relationships by way of the Smart-PLS. In light of the findings, it was determined that the interaction between HC and ATU was mediated by FSK, and the interaction between HC and the SN was mediated by FSK. Consequently, this research presents a variety of theoretical and practical implications to give clues for consumers' health regarding food supplement consumption.

Abstract
In response to the detrimental health- and environmental impacts of European consumers' dietary patterns, Nutri-Scores and Eco-Scores have been introduced on packages as guidance for choices. Whereas the scores are promising to improve food choices from a nutritional point of view, the scant available literature suggests very limited effects on the environmental impact of food choices. Therefore, there remains a need to explore ways to bring about improvements in both areas. As a growing share of consumers buys food groceries online, new opportunities to steer food choices are being created. This article explores the potential of several digital functionalities to further stimulate healthier and pro-environmental food choices amongst consumers. These functionalities included product recommendation agents, product scores, a real-time average impact score of the chosen food basket and a personalised social norm. Those were tested in a two-stage randomized controlled trial with 1000 Belgian household food decision makers in a mock-up E-grocery. Indices reflecting the nutritional quality (NQI) and environmental impact (EII) of the selected food baskets were calculated. The results indicate that at first, displaying a combined Nutri- and Eco-Score at product level led to improved NQI's, but not EII's. However, the scores also led to shifting behaviour in EII's when facilitated with recommendation agents. The display of the average impact scores of the selected basket and of social norms did not lead to additional improvements. Hence, a combined Nutri- and Eco-Score labelling system is recommended, but an enabling environment to consider both scores is important to realise a shift towards more healthy and environmentally friendly food choices. Apart from manifesting healthier and environmentally friendly products with a centralised labelling system, improving their accessibility should be considered at least as important for behavioural changes.

Abstract
Obesity and state of being overweight are beginning to be treated as global epidemics. In this context, health professionals are increasingly acting as expert opinion leaders that use social media to connect with the public, in order to promote healthy lifestyles and provide specific recommendations for different product categories, including fresh, processed, and ultra-processed meat products. This study investigates how exposure to content created by health professionals, and posted on social media, influences consumers’ attitudes. For this purpose, the collaboration of one relevant nutritionist influencer in Spain has been obtained. The online survey created has provided 4.584 responses, received from followers (from May to June 2019). After applying a partial least squares path modeling approach, the results suggest that trust in the content shared, the perceived credibility of the professional sharing the information and the informative value, determine the strength with which consumers acquire more knowledge about endorsed products, develop a favorable predisposition towards them, prefer them over their options, and modify their behaviour by purchasing them, instead of their usual foods. The link is stronger, in the case of trust and influencer’s credibility, than for informative value. However, the latter has an indirect effect on the attitude phases through the former.

The sustainability liability revisited: Positive versus negative differentiation of novel products by sustainability attributes. Appetite 2021; 167:105637.

Abstract
In response to a growing consumer trend towards meat reduction and more plant-based diets, the food industry develops meat-reduced food innovations, such as blended products which replace part of their meat with plant-based ingredients. These products are usually promoted as being more sustainable than existing products. However, it is not clear whether sustainability attributes are used by consumers to positively or negatively differentiate these novel products from existing ones. We investigated these two possibilities in two studies. In Study 1, we tested in an online survey whether positive sustainability attributes of novel food products generally affect purchase intentions in a positive or negative way, mediated by taste expectations. In Study 2, we investigated in a field study in a restaurant the choice of a novel blended meat product versus a classic product. In particular, we tested whether the blended meat product is more likely to share positive attributes with a classic alternative than negative attributes and might therefore lack the power of positive differentiation. The results of Study 1 show a positive differentiation by sustainability when taste attributes are equal compared with a classic product. However, Study 2 demonstrates that the mechanisms of a negative differentiation might attenuate these positive effects, because positive hedonic attributes of the novel blended-meat product more likely apply also to the classic product than the negative attributes.

Chu R, Tang T, Hetherington MM. The impact of food packaging on measured food intake: A systematic review of experimental, field and naturalistic studies. Appetite 2021; 166:105579.

Abstract
Chronic, excess energy intake contributes to overweight and obesity. Solutions are needed to guide consumers towards portion control, especially for high energy density (HED), palatable foods. Food packaging, a key element of the eating environment, offers a potential solution. To investigate whether packaging design influences measured food intake, a systematic search was undertaken in four electronic databases (Ovid Medline; Ovid PsycInfo; Ovid Embase and Web of Science) across the previous decade. This process yielded 1671 discrete papers, of which 23 articles containing 40 relevant studies were retrieved. Most (n = 36) of the manipulated packaging features influenced consumption quantity with the largest effect sizes observed for packaging which guided consumers either by on-pack cues or structural features. For example, images on the front of the pack, packaging size, as well as partitioning and resealability all helped to reduce food intake. However, individual differences and attentional focus mediate packaging effects. Overall, packaging features can help to limit intake of HED foods and increase intake of nutrient-dense foods (e.g., carrots). Future studies on packaging for portion control (downsizing) might benefit from long term, randomised control trials to test effects outside of the laboratory context and applied to everyday consumer usage.

[PMID: 33920697 PMCID: PMC8073205 DOI: 10.3390/foods10040886] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 04/06/2021] [Accepted: 04/14/2021] [Indexed: 11/17/2022] Open
Abstract
Foods' overall liking (OL) and purchase intent (PI) are influenced by visual inputs, such as color cues and serving plate types. Cheese-flavored tortilla chips (CFTC) from two formulations (A and B) with a noticeable color difference (∆E = 4.81) were placed on different serving plates (plastic, foam, and paper) and presented monadically to N = 83 consumers using a randomized/balanced block design in two sessions. Consumers evaluated likings of overall visual quality, color, crunchiness, saltiness, overall flavor (OF), and OL using a 9-point-hedonic scale, attribute appropriateness on a 3-point-just-about-right (JAR) scale, and PI using a binomial (Yes/No) scale. Color differences between A and B influenced crunchiness and saltiness liking and perception, which together with OF liking and formulation, mainly determined OL of CFTC. Although having similar fracturability (N) and sodium content, formulation A had higher crunchiness and saltiness likings. PI was influenced by crunchiness, saltiness, and OF liking with 37, 49, and 60% increases in PI odds per liking-unit increase, respectively. Plate type had minimal effect on the sensory liking of CFTC. The brighter and less-yellow color of CFTC could positively influence liking of crunchiness and saltiness, which significantly contributed to OL and PI. These findings are useful to understand consumers' acceptability and perception of foods when varying visual inputs.
