Currently, limited and contradictory evidence is available regarding associations between environmental values, nutrition literacy, PEHFs, and plant/animal protein food consumption. Design/methodology/approach An online survey measuring environmental values; nutrition literacy, distinctively based on previous (2007) and most recent (2019) FG messages; PEHFs; and annual changes in the consumption of protein foods was sent to Quebec residents (N = 128). Findings Greater nutrition literacy of both 2007 and 2019 FGs and greater environmental values were associated with greater PEHFs (ß = 0.248, p < 0.01; ß = 0.209, p < 0.05; ß = 0.423, p < 0.001, respectively). Greater PEHFs was associated with greater consumption of plant protein foods (ß = 0.405, p < 0.001). Greater nutrition literacy of the 2007 FG was associated with greater consumption of animal protein foods (ß = 0.409, p < 0.001), whereas greater nutrition literacy of the 2019 FG was linked to lower consumption of animal protein foods (ß = −0.225, p < 0.05). Practical implications Enhancing PEHFs may require increasing general FG nutrition literacy and strengthening environmental values. To encourage plant protein food consumption and decrease animal protein food consumption, the authors recommend promoting PEHFs and increasing nutrition literacy based on newest FG recommendations. Originality/value This new evidence may help develop strategies promoting PEHFs and plant protein food consumption, thus increasing uptake of new FG recommendations.","PeriodicalId":9231,"journal":{"name":"British Food Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135199354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this reason, aspiring to excellence should be one of the priorities in the industry, which should mean, among other things, enhancing those aspects related to food with the greatest impact on the maximum level of customer satisfaction. However, to the authors knowledge, this research line has not been addressed before in the context of Peruvian restaurant, so that this research focuses on assessing the influence of food – through the concept of food values –, on the probability of reaching the maximum level of satisfaction both with the food consumption experience and with the foods consumed in restaurants in Peru. This research also takes into account differences according to the geographical origin of the customers. Design/methodology/approach An in-person survey of customers was conducted at the exit of different flagship restaurants with a high level of recognition and tourist orientation in the department of Ayacucho (Peru) between September and November 2022. Five restaurants acknowledged as tourist restaurants were selected for this study, of which, one has been officially granted the status of Tourist Restaurant and One Fork, in accordance with the Peruvian legal regulations. A total of 468 valid questionnaires were collected. The database was analysed using descriptive statistics, principal component factor analysis for food values, and binary logistic regressions. Findings The following food values factors emerged from the factorial analysis: “Image and Accessibility (IAA)”, “Ethics and Sustainability (EAS)” and “Natural Food-Safe (NFS)”. For the overall sample, IAA is more influential in the probability of obtaining the maximum level of both satisfactions (i.e. satisfaction with the food consumption experience and with the foods consumed in restaurants in Peru). In second place, EAS, as well as NFS (the latter one with a significance level of 90%), also affect, in this order, the probability of obtaining the highest level of satisfaction, but only with the foods consumed. When the geographical origin of the customer is considered (regional, national, international), interesting findings appear. For national customers, IAA is the factor with the greatest impact on the probability of achieving the maximum level of the endogenous satisfaction variables considered, followed by EAS, whilst for regional customers, only EAS is found to be influential in the probability of obtaining the maximum level of both types of satisfaction. For international customers, no factor is found to exert a significant influence. Originality/value This is the first study to assess the influence of food values on the maximum level of satisfaction among restaurant customers in Peru with both the food consumption experience and the foods consumed.

It will also reveal the foreign tourists' food consumption value and explore its influences on the destination's food image. Design/methodology/approach The data collection was performed from 433 foreign tourists who visited Delhi, India, using a structured survey instrument and chief constructs were measured as the first-order reflective variables. The 39 items associated with the LFC value underwent both exploratory and confirmatory evaluations. The authors employed partial least square structural equation modeling (PLS-SEM). The model's discriminant and convergent validity, consistency and overall fit were evaluated using confirmatory factor analysis (CFA). Findings The findings revealed that “tourists' attitudes and behaviors toward the local cuisine” had a significant and positive influence on their “intention to visit/revisit” and “intention to recommend”. Also, “destination food image” significantly and positively influenced the “intention of tourist to visit/revisit”; however, it negatively and insignificantly influenced the “intention of tourists to recommend”. Research limitations/implications This research used five variables related to LFC—quality, health/nutrition, emotion, prestige and price—that impact tourists' attitudes and behaviors toward local foods in Delhi. However, in addition to these constructs, other factors or constructs may be involved that could affect the tourists' attitudes and behaviors. Future studies might explore and include these constructs to provide a more comprehensive image of Delhi's LFC value. Originality/value Understanding tourists' food-linked behaviors is critical for effective market conduct. However, the interrelations between travelers' destination food image, LFC value, their perceptions of the local cuisine and behavioral intentions are still unknown, and this will be one of the first attempts to discuss these behaviors.","PeriodicalId":9231,"journal":{"name":"British Food Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135768957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study identifies relevant restaurant segments in relation to sustainable practice-based service innovation so that effective actions to raise awareness and train managers and staff may be developed. Segmentation has been identified as a key tool when designing strategies and proposing actions. Yet, the use of segmentation techniques is still scarce regarding service innovation and sustainability in restaurants. Design/methodology/approach A segmentation analysis was carried out applying the CHAID algorithm from 300 valid questionnaires completed by restaurant owners or managers from coastal Ecuador, where tourism and gastronomy may be drivers of service innovation. Findings A typology of restaurants based on the sustainability-service innovation interrelation suggests three final segments: sustainable innovators focused on the value chain, moderate innovators focused on saving resources and restaurants with a low innovative profile. Practical implications The three segments derived from the analysis present differences in terms of the degree of implementation of sustainability practices, as well as in terms of the demographic profile of the restaurant manager. These segments are measurable, substantial, accessible and actionable, so that tailored initiatives to raise awareness and boost sustainability-oriented innovativeness among restaurant owners/managers may be targeted to each group of establishments.

This study examined the food choices and perceptions of adult consumers dissatisfied with their body image about food products available in the “healthy foods” section of a Brazilian supermarket. Design/methodology/approach Exploratory, descriptive and qualitative study. Body image dissatisfaction was assessed with the self-reported silhouette scale validated for the Brazilian population. Chosen items were classified according with degree of processing. Face-to-face interviews were conducted with 26 men and women and transcribed and thematically analyzed. Findings Participants chose 81 food products, most of which (53%) were ultra-processed. Thematic analysis revealed that participants were motivated mainly by consumption habits, preference, convenience and brand loyalty. Participants questioned the concept of health promoted by the supermarket and suggested that the kind of food items available in “healthy foods section” may confuse consumers about the healthfulness of packaged processed foods (PF). Despite being critical of the concept of healthfulness promoted by the supermarket, participants predominantly selected ultra-processed foods (UPF) mentioning health-related motivations for their selection, revealing a realm of contradictions.
