Psychological Factors Influencing Willingness to Purchase Wild–Edible Plants and Food Products from Wild–Edible Plants

Modern agriculture faces many challenges. At the same time, it is necessary to provide healthy and sustainable food for humanity in growing conditions that are facing numerous problems, including climate change. Different strategies can be applied to deal with climate change, such as using different crop technologies. In this context, the application of wild–edible plants as a source of biodiversity, vitamins, and minerals for the human diet is interesting. Consumers’ behaviour toward wild–edible plants is a relatively new topic in marketing research, so this paper investigated the impact of certain psychological factors on consumers’ willingness to purchase wild–edible plants and food products. The study was performed on a sample of consumers of produce from farmers’ markets in Istria County, Croatia, and the data were collected via a questionnaire. The univariate and multivariate analyses provided evidence that consumers’ purchase intentions are determined mainly by their positive attitudes regarding trying new and unfamiliar foods. Furthermore, customers’ intentions to purchase food products containing wild–edible plants were determined by their attitudes regarding wild–edible plants and their subjective knowledge.

Effects of Risk and Time Preferences on Diet Quality: Empirical Evidence from Rural Madagascar

Malnutrition is a major concern in Madagascar. Eating a wide variety of nutritious food is necessary because Malagasy diets heavily rely on rice consumption. This study explored the barriers to dietary change towards diversification from the perspective of consumer behaviour. We analysed the impact of risk and time preferences on dietary diversity using economic experiments conducted with 539 rural lowland rice farmers in Central Highlands in Madagascar. The results showed that risk-averse or impatient individuals were more likely to have lower Household Dietary Diversity Score (HDDS), indicating poorer diet quality. Risk-averse people may not want to add different foods to meals as they perceive unfamiliar food as a ‘risk’; people who prefer immediate gratification may fail to invest in nutritious diets now to achieve better health in the future. Additionally, higher HDDS was observed among households with a female head who earned off-farm income and who had frequent market visits. These findings contribute to explaining the limited shift in nutritional transition in Madagascar and provide useful insights into nutritional policies promoting healthier food choices. Depending on the preferences, more focused support such as nutritional education, financial support, market development, and pre-commitment mechanisms could be provided to reward long-term nutritional benefits.

How does food neophobia effect local food preferences?

The term "food neophobia" is used to describe the behaviour of individuals who exhibit a fear of new or unfamiliar foods. The phenomenon of food neophobia can influence the consumption of novel foods by tourists during their visits to unfamiliar destinations. This paper sets out to determine the moderating role of food neophobia in the effect of local food consumption value on attitudes and behavioral intentions towards local food. In this context, a questionnaire was used to measure the values, attitudes, behavioral intentions and food neophobia levels of 509 foreign tourists visiting Turkey (Istanbul province) towards Turkish food. The findings show that consumption values such as emotional, epistemic, health, taste/quality and price value the attitudes of foreign tourists towards local foods. In addition, food neophobia has a moderating role in the effects of health value and epistemic value on attitudes towards local foods.

Food Neophobia in Children Aged 1-6 Years-Between Disorder and Autonomy: Assessment of Food Preferences and Eating Patterns.

Food neophobia, defined as fear or aversion to eating new or unfamiliar foods, is a significant challenge, especially in the context of preschool children. In the scientific literature, this phenomenon is often described as a natural developmental stage, but its severity and impact on preferences and eating patterns still raise many questions. The purpose of the present study was to assess the prevalence of food neophobia in children aged 1 to 6 years and to analyze its relationship with eating habits, preferences, and eating patterns. The study was conducted using a proprietary questionnaire and validated research tools such as the Child Feeding Scale (MCH-FS) and Food Neophobia Scale (FNS). The study included 345 children, of whom 59.1% were observed to be at significant risk for food neophobia. The results of the study suggest that food neophobia is not a common phenomenon in children aged 1-2 years but becomes more pronounced later in childhood. Another important finding was that food neophobia shows a stronger association with established eating patterns than with individual taste preferences. Considering these results, this phenomenon should be considered not only as a natural part of child development, but also as a potential indicator of eating disorders that may require intervention. These findings underscore the need for further research that could deepen the understanding of the mechanisms governing food neophobia and its long-term consequences for child health.

Food safety concerns and purchase choices among poor households in the urbanising global south: the case of Dhaka, Bangladesh

This article looks into the daily food shopping practices of poor urban households in Dhaka, Bangladesh. A practice theory-based approach is used to explore their coping strategies in response to food safety concerns. By applying an exploratory sequential mixed-method approach, two groups of shoppers are compared: recently arrived migrants and established residents, as recently arrived migrants are expected to face an unfamiliar food shopping environment and therefore need to reconsider their daily food shopping practices. The results describe the elements of food shopping practices: food items, retail outlets, affordability, social networks, and relations to work. We identified the absence of freshness, undesirable substances, and the need for more information about the production process as the primary food safety concerns. Among both shopper groups, the harmful consequence of applying the chemical 'formalin' to food is considered the most prominent food safety concern. Major coping strategies include identifying (un)safe food, proactive selection, and establishing and maintaining social relationships. The two groups have similarities and differences in using skills and competencies to mitigate their food safety concerns in everyday shopping practices. Recently arrived migrants have to adapt to urban lifestyles and reconfigure their food safety concerns into their daily food shopping practices.

“What is this?”: Multisensorial explorations of food with and without sight

The relationship between sensorial experiences and language during food consumption has been investigated in a diversity of settings and activities, showing a variety of sensorial practices and possible ways of discursively expressing them. In this paper, we focus specifically on activities where individuals encounter unfamiliar food, suspending expected synaesthetic associations between sensory features. Using audio and video recordings of dinner interactions in restaurants offering high-end creative cuisine and dining experiences in complete darkness, we show how the participants move from eating to tasting and engage in a multisensorial exploration of the food, where sight is either absent or insufficient to solve the puzzle of what it is they are eating. We find that this exploration commonly begins with a recurring interactional practice: the question “what is this?“, initiating a sequence that reveals a public collective engagement with the food among participants. Drawing on ethnomethodology and conversation analysis, we investigate the sequential environments in which “what is this?” prototypically occurs, the various actions it implements, its turn design (displaying a more or less unknowing stance), as well as how it is subsequently responded to within the participants’ project of identifying the food. We examine how the “what is this?” inquiry mobilizes various linguistic resources, in a way that is deeply embedded in multisensorial examinations of the food that are (made) available to co-participants, publicly seeable in high-end gastronomic restaurants, and publicly hearable in dark restaurants. Our findings contribute to naturalistic interactional research on commensality and multisensoriality, with particular relevance for scholarship addressing the primacy and limitations of sight.

Development and validation of Japanese version of alternative food neophobia scale (J-FNS-A): association with willingness to eat alternative protein foods.

Food neophobia (FN) is a psychological trait that inhibits one's willingness to eat unfamiliar foods. It is related to the acceptance of insect foods and cultured meat, which are major protein alternatives to conventional meat, and is an important personality trait for understanding the near-future food industry. However, the factor structure of Pliner and Hobden's FN scale (FNS) is unstable due to respondents' cultural backgrounds. Thus, we aimed to develop a Japanese version based on the alternative FNS (FNS-A), the most recent revised version, and to examine its validity. Four online surveys (preliminary 1: n = 202; preliminary 2: n = 207; main: n = 1,079; follow-up: n = 500) were conducted on the FNS-A. For the main survey, Japanese respondents (aged 20-69 years) answered the Japanese version of the FNS-A (J-FNS-A), their willingness to eat (WTE), and their familiarity with hamburgers containing regular protein foods (ground beef, tofu) and alternative protein foods (soy meat, cultured meat, cricket powder, algae powder, and mealworm powder). Consistent with the FNS-A, confirmatory factor analysis assuming a two-dimensional structure (approach and avoidance) showed satisfactory model fit indices. The mean J-FNS-A score (Cronbach's α for 8 items = 0.83) was 4.15 [standard deviation (SD) = 0.93]. J-FNS-A scores were not associated with age and gender, whereas a greater than moderate association was found with WTE hamburgers containing alternative protein foods (rs = -0.42 to -0.33). The strength of these negative associations increased as food familiarity decreased (r = 0.94). The test-retest reliability at 1 month was also satisfactory (r = 0.79). The validity of the J-FNS-A was confirmed. Higher J-FNS-A scores (mean = 41.51, SD = 9.25, converted to Pliner and Hobden's FNS score) of the respondents suggest that Japanese people prefer conservative foods. This scale could predict the negative attitudes toward foods with low familiarity, such as alternative proteins. The J-FNS-A appears to be a useful psychological tool for assessing Japanese food neophobia tendencies and predicting novel food choices of Japanese individuals.

Adherence to Mediterranean Diet and Food Neophobia Occurrence in Children: A Study Carried out in Italy.

Food Neophobia (FN), defined as the reluctance to eat new or unfamiliar foods, mainly concerns fruit, vegetables, and legumes, typical of the Mediterranean Diet (MD). Considering these premises, this study aimed to clarify the relationship between FN and AMD in a sample of Italian children and their association with some socio-demographic factors and children's nutritional status. A sample of 288 children aged 3-11 years participated in an assessment carried out with a questionnaire evaluating FN and AMD, respectively, with the Child Food Neophobia Scale (CFNS) and the KIDMED test. Most of the sample showed an intermediate (67.3%) or high level of FN (18.1%), with high rates among 6-11-year-old children (63.9%) and especially in those who were the only child (50%). The AMD was mostly low (29.5%) or medium (54.8%) and reached lower levels among higher neophobic children (51.9%; p value < 0.05). The present results confirm the study hypothesis that FN is a driver of MD abandonment and shows the positive effects on children's eating habits and siblings. Finally, this study proves the relevance of adopting effective feeding strategies against FN to avoid its maintenance in adulthood and the detrimental effects on future overall health and well-being.

Infant Complementary Feeding Methods and Subsequent Occurrence of Food Neophobia-A Cross-Sectional Study of Polish Children Aged 2-7 Years.

The study used an anonymous survey questionnaire consisting of five parts as the research tool. The first part of the questionnaire was a metric and concerned the socio-demographic data of the parent/guardian and their child. A standardised questionnaire assessing food neophobia among children was used to assess food neophobia: the Food Neophobia Scale-Children (FNSC). In the study group, 171 children (29.23%) had a low risk of food neophobia according to the FNSC, 182 children (31.11%) had a medium risk of neophobia, and 232 children (39.66%) had a high risk of neophobia. A correlation was observed between the age and the risk of food neophobia (p = 0.0002). Statistically significant differences were found between children aged 2 and 4 (p = 0.003) and children aged 2 and 5 years (p = 0.049). We observed no correlation between gagging (p = 0.88557), choking (p = 0.17597), and needing medical intervention (p = 0.61427) and the risk of associated neophobia. In the study group of children, the highest risk of food neophobia was characterized by children aged 4, 5, and 7 years. The length of breastfeeding and exclusive breastfeeding did not affect the risk of food neophobia. In the month in which complementary feeding (CF) was introduced, the children were fed using the baby-led weaning method (BLW method), and introducing puree and puree with lump food into the children's diet also did not affect the risk of food neophobia. It was shown, however, that children whose mothers observed difficulties during CF and whose children had a vomiting reflex and spat food out of their mouths during CF were more likely to develop food neophobia at the preschool age.

How sweet is too sweet? Measuring sweet taste preferences and liking in familiar and unfamiliar foods amongst Dutch consumers

Sweet taste preference and liking have been assessed with various methods, yet there is no consensus in the literature on which method is most sensitive across a range of foods. The current studies explored several methods to assess sweet taste preference, liking and perceived intensity across various familiar and unfamiliar foods in Dutch consumers. In experiment 1, five different sweet foods, each with five sweetness concentration levels were evaluated on preference, liking and perceived intensity, using two methods for measuring liking and preference: ranking (n = 10), rating (n = 10); one for measuring perceived intensity: rating (n = 10); and one combining preference, liking and perceived intensity: structured napping (n = 10). The ranking method, despite having the highest discriminative power, gave no indication of inter-sample spacing nor absolute scores. In subsequent studies, ranking was thus combined with rating as “Ranking on a scale” (RoS). Experiments 2 (N = 31), 3 (N = 28) and 4 (N = 28) tested the RoS method across various familiar and unfamiliar foods and/or food forms. In Experiments 2 and 4, inverted-U-shaped hedonic responses were observed for all foods, and differences in preference for different sweetness concentration levels were detected. Experiments 3 and 4 showed that familiar foods were more liked than unfamiliar ones across all sweetness levels (Experiment 3 (F(1,1322) = 14.8, p <.001); Experiment 4 (F(1,803) = 38.1, p <.001)). Hence, RoS seems to be a viable method for assessing sweet taste preferences in both familiar and unfamiliar foods, among consumers. In future work we will apply this method to better understand the role of sweet taste exposure on preferences for a range of sweet foods.

Exposure effects to unfamiliar food advertisements on YouTube: A randomized controlled trial among adolescents

Despite the societal relevance of the topic, experimental evidence on the effects of digital food marketing on adolescents' food attitudes and choice behavior remains relatively scarce. Drawing on the logic model explaining the influence of marketing on health-related responses, the current between-subjects experiment sought to (i) evaluate the effects of exposure to unfamiliar food advertisements on YouTube with respect to adolescents' advertisement and brand recall, brand recognition, attitudes, and food choice in a hypothetical scenario; and (ii) compare the effect of exposure to advertisements promoting healthy (vs. unhealthy) food. Uruguayan adolescents (N = 433; 51% female) were randomly assigned to one of four experimental groups: a control group not exposed to any advertisement, a non-food group exposed to a clothing advertisement, an unhealthy food group exposed to an advertisement promoting a burger, and a healthy food group exposed to an advertisement promoting a salad. Following exposure to the advertisement, participants provided responses linked to advertisement and brand recall, brand recognition, attitudes, and food choice. The findings revealed that the largest effects of exposure to food advertisements emerged for advertisement recall and brand recognition (i.e., the most proximal steps in the logic model). Further, the burger advertisement was more easily recalled than the salad and the non-food advertisements, presumably due to its higher reward value. The effects of the food advertisements on brand attitudes and food choices were more inconclusive, although participants’ sex and frequency of burger consumption consistently moderated the impact of ad exposure on these outcomes, through mainly influencing males and adolescents who consumed burgers more frequently. Together, these results contribute to the literature on the effects of digital marketing by providing causal evidence for the role of advertisement exposure on adolescents’ advertisement and brand recall, brand recognition, brand attitudes, and choice behavior.

Dyadic analysis of the relationship between food neophilia and dietary quality among older heterosexual couples: Findings from the NutriAct Family Study

Despite the benefits of a varied and balanced diet, many people do not follow the recommendations of dietary guidelines. One factor considered to influence food choices and therefore potentially important in promoting adherence to dietary guidelines is the willingness to try unfamiliar foods, also referred to as food neophilia. Given the importance of social influences on food choices, particularly among couples, food neophilia might influence not only one’s own dietary quality but also that of one’s partner. Using cross-sectional data from N = 390 older heterosexual couples (M = 64.0 years), the present study aimed to examine the relationship between food neophilia and dietary quality in the intra-couple context. For this purpose, participants completed the Variety Seeking Tendency Scale (VARSEEK) to measure neophilia. Dietary quality was scored using the NutriAct diet score, which was calculated based on a comprehensive assessment of dietary intake consisting of short-term (repeated 24 h-FLs) and long-term (FFQ) self-report instruments. An Actor-Partner Interdependence Model (APIM) was applied to examine potential intra- and interpersonal effects. The results of our dyadic analysis revealed a domination pattern, in that women's food neophilia was positively associated with both their own and their partner’s dietary quality, while men's food neophilia showed no association with the dietary quality of both partners. This highlights the dominant role of women in shaping older couples' dietary habits, with their food neophilia emerging as a contributing factor. Our findings underscore the need for further in-depth research to develop interventions targeting health-promoting eating in older age using the dynamics within couples. Future studies could explore interventional strategies to support women’s dominant role while empowering both partners to collaboratively shape their dietary habits, emphasizing the potential benefits of trying unfamiliar foods.

Nematode dynamics in an African dolomite cave: What is the role of environmental filtering in spatial and temporal distribution?

Caves present unique and interesting habitats, captivating scientists in discovering new species and disentangling unfamiliar food webs. However, cave-dwelling nematodes remain poorly studied with minimal evidence supporting their ecological relevance. Therefore, the present study was aimed at investigating the role of selected environmental filters over temporal (seasonal) and spatial (site location) scales on the community dynamics and functional diversity of cave-dwelling nematodes in Dripkelder Cave (South Africa). Multiple sampling sites, with varying levels of exposure to surface material, were investigated over four consecutive seasons. Selected microhabitat characteristics were also measured including sediment respiration, organic and active carbon, moisture content, pH, electrical conductivity, texture, and temperature. The results indicated significant effects on nematode community dynamics from exposure to surface material and environmental filters (including a physical restriction between the entrance area and deeper cave sites). Furthermore, clear temporal trends evidenced the effect of seasonality. An example of this was the rapid response of nematode colonisers (Rhabditis sp.) to the introduction of food and later transitioning to dauer larvae. Finally, multiple trophic groups associated with more isolated cave habitats indicated the potential role of nematode functional diversity in food web dynamics. This study showed that nematode dynamics in caves are likely more complex than originally believed.

A Rasch-based validation of the Indonesian version of the food neophobia scale

This study aims to translate and validate the Indonesian version of the Food Neophobia Scale (ID-FNS), a scale used to measure the tendency to reject new or unfamiliar foods. Despite being adopted in many countries over 30 years, its validation and adaptation reports are unavailable for Indonesian. This measure was tested on 1632 participants aged 18–60 years (M = 26.4, SD = 1.04) spread across 28 provinces in Indonesia. Rasch analysis was adopted for this study. The results of our analysis suggested that no items from the original FNS scale were eliminated. In summary, the ID-FNS is the first to measure food neophobia in the Indonesian context with adequate psychometric properties.

High arousal as the source of food rejection in food neophobia

Food neophobia (FN) at moderate to high levels is very common among adult populations in all cultures and is usually defined in terms of rejection of unfamiliar foods. However, food rejection in FN is only partly related to food familiarity. Experimental and survey studies have suggested that unpleasantly high arousal may be induced by food novelty, but also be produced by foods with intense or complex flavours, that are perceived as dangerous or foreign, or that have unusual ingredients. Liking for foods with these characteristics have recently been shown to be strongly negatively associated with FN. Thus, induced high arousal may underlie food rejection in FN. Here, we collected familiarity, liking and arousal ratings, and scores on the standard Food Neophobia Scale from more than 7000 consumers in four countries – Australia, United Kingdom, Singapore, Malaysia – for a series of food names that were manipulated to produce standard and ‘high arousal’ (variant) versions of the same foods. Consistent across all four countries, arousal ratings increased, and liking decreased, with decreases in food familiarity. Variant food names were always associated with ratings of higher arousal than the standard names. The variant foods were generally less familiar than the standard foods, although this was not a necessary condition for their higher arousal ratings, suggesting that the other arousal-inducing factors (e.g., flavour intensity) also played a role. Across all foods, arousal ratings increased, and liking ratings decreased, as FN increased, but these effects were accentuated for the variant foods. The consistency of these effects across multiple countries supports a view that arousal is universally a strong determinant of liking for foods and that this underlies the rejection of foods, familiar and novel, in FN.

11- to 13-Year-Old Children's Rejection and Acceptance of Unfamiliar Food: The Role of Food Play and Animalness.

Promoting children's healthy food behavior is important in reducing the risk of developing obesity; it is therefore relevant to investigate methods to promote healthy food choices. This study's aim was to investigate differences in rejection-acceptance mechanisms related to unfamiliar foods depending on the inclusion of tactile exercises prior to cooking and food origin. Participant observation was applied in a school setting. Eight fifth and sixth grade classes were recruited from four Danish schools (n = 129). The classes were divided into two groups: animal (AG; quail) and nonanimal (NAG; bladderwrack). AG and NAG were subdivided into two groups: food print (FP) and no food print (NFP). Applied thematic analysis was applied. During preparation/cooking, NFP displayed disgust-related rejection, whereas FP displayed inappropriateness-related rejection. FP exhibited more playful behavior. Inappropriateness and animalness drove AG rejection. NAG rejection was driven by the slimy texture of the food and the perception of it 'not being food'. Acceptance was driven by taste and familiarity. In conclusion, the inclusion of tactile exercises could increase children's exploratory food behavior, and the promotion of children's healthy food behavior should not solely focus on choosing foods deemed safe and familiar, since, despite rejection during cooking, acceptance is ultimately possible.

Exploring the Longitudinal Stability of Food Neophilia and Dietary Quality and Their Prospective Relationship in Older Adults: A Cross-Lagged Panel Analysis

Poor dietary quality is a major cause of morbidity, making the promotion of healthy eating a societal priority. Older adults are a critical target group for promoting healthy eating to enable healthy aging. One factor suggested to promote healthy eating is the willingness to try unfamiliar foods, referred to as food neophilia. This two-wave longitudinal study explored the stability of food neophilia and dietary quality and their prospective relationship over three years, analyzing self-reported data from N = 960 older adults (MT1 = 63.4, range = 50-84) participating in the NutriAct Family Study (NFS) in a cross-lagged panel design. Dietary quality was rated using the NutriAct diet score, based on the current evidence for chronic disease prevention. Food neophilia was measured using the Variety Seeking Tendency Scale. The analyses revealed high a longitudinal stability of both constructs and a small positive cross-sectional correlation between them. Food neophilia had no prospective effect on dietary quality, whereas a very small positive prospective effect of dietary quality on food neophilia was found. Our findings give initial insights into the positive relation of food neophilia and a health-promoting diet in aging and underscore the need for more in-depth research, e.g., on the constructs' developmental trajectories and potential critical windows of opportunity for promoting food neophilia.

EEG measures of attention toward food-related stimuli vary with food neophobia

Humans differ strongly in their willingness to try novel foods. Hesitance to try new foods is referred to as food neophobia. Understanding food neophobia is important, as it can be a significant barrier to adopt a healthy, balanced or plant-based diet. We here use electroencephalogram (EEG) recordings to obtain insight in the early attentional processes towards food stimuli as a function of food neophobia. 43 Dutch participants completed the food neophobia scale after which they were presented with pictures of familiar and unfamiliar foods and a 15-minute movie about the origin and production of an unfamiliar food. We extracted two EEG-based metrics of attention: the late positive potential (LPP) amplitude in response to the food pictures, and inter-subject correlations (ISC-EEG) during the movie. The latter is a novel metric, based on similarities in EEG over time between individuals who are presented with the same stimulus, and suitable for examining attention towards continuous stimuli such as movies. Additionally, participants were asked to taste familiar and unfamiliar soups, and they were asked to rate the pictures and soups for valence and arousal. ISC-EEG and the LPP amplitude increased and sip size decreased with food neophobia, not only for unfamiliar food pictures, but also for familiar food pictures. Self-reported emotional experience was affected by food neophobia for unfamiliar food pictures or soups, but not for familiar ones. We conclude that food neophobia is associated with increased attentional processing and immediate implicit behavior, for all food stimuli and not only for unfamiliar food stimuli. This indicates that all food-related stimuli are of high importance to food neophobic individuals and that self-reported emotion does not capture the entire experience of food. The results also indicates that, unlike the name suggest, food neophobia does not only affect processing of novel foods, but of any food regardless of familiarity.

A narrative review on food neophobia throughout the lifespan: relationships with dietary behaviours and interventions to reduce it.

Food neophobia is defined as the unwillingness to taste new foods and the avoidance of unfamiliar foods. This eating behaviour is a complex issue, and both genetic and environmental factors play a role in it. The aim of this review is to understand its relationships with dietary behaviours throughout the lifespan and to examine the impact of interventions on food neophobia. A literature search was performed using the PubMed, Web of Science, Cochrane Library and ScienceDirect databases. As a result of the screening, a total of 139 studies, seven of which were intervention studies, were included in this review. According to current evidence, food neophobia is negatively associated with the acceptance of not only novel/unfamiliar foods but also familiar foods. Many studies have shown that food neophobia is negatively associated with the hedonics and consumption of core foods, especially vegetables and fruits. Individuals with higher levels of food neophobia are less familiar with many foods, but familiarity is a prominent motivator in food choices for these individuals. Therefore, it may be considered a barrier limiting diet quality and this trend is similar for both children and adults. However, food neophobia is not an unchangeable personality trait. Intervention studies have pointed out that educational programmes and food-related activities that increase familiarity and exposure to foods and create positive attitudes towards and positive experiences with foods can reduce food neophobia. The results highlight that people with high food neophobia need more support to improve their diets and the quality of dietary behaviour.
