Kamei M, Nishibe M, Horie F, Kusakabe Y. Development and validation of Japanese version of alternative food neophobia scale (J-FNS-A): association with willingness to eat alternative protein foods. Front Nutr 2024; 11:1356210. [PMID: 38863584 PMCID: PMC11165137 DOI: 10.3389/fnut.2024.1356210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 05/14/2024] [Indexed: 06/13/2024] Open
Abstract
Introduction 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. Methods 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). Results 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). Discussion 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.

Neuwald NV, Pearce AL, Adise S, Rolls BJ, Keller KL. Switching between foods: A potential behavioral phenotype of hedonic hunger and increased obesity risk in children. Physiol Behav 2023; 270:114312. [PMID: 37543104 DOI: 10.1016/j.physbeh.2023.114312] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 06/08/2023] [Accepted: 07/31/2023] [Indexed: 08/07/2023]
Abstract
CONTEXT Reward-based eating is a trait that increases risk for eating in the absence of hunger (EAH) and obesity. Eating behaviors such as switching more frequently between different foods may increase intake during EAH by delaying the onset of sensory-specific satiation (SSS); however, this question has not been empirically tested. OBJECTIVES 1) Test whether switching between foods mediates the relationship between reward-based eating and EAH intake. 2) Test whether switching between foods during EAH moderates the relationship between reward-based eating and weight status. METHODS Data were analyzed from a study assessing decision-making in children (n = 63 children; 9.4 ± 1.4 years, 77.0 ± 22.4 BMI%tile). Reward-based eating was quantified using the Children's Eating Behaviour Questionnaire. EAH was assessed as the amount of palatable food consumed following ad libitum consumption of a standard meal. Videos of eating behavior were coded for eating time, number of different foods consumed, and food switches. Ordinary least squares regressions were conducted to test hypotheses. RESULTS Switching was positively associated with EAH intake for both kcal (p < 0.01) and grams (p < 0.01) such that each additional switch was associated with an increased intake of 17.0 kcal or 3.5 gs. Switching mediated the relationship between reward-based eating and EAH (p < 0.01) such that more frequent switching fully accounted for the positive association between reward-based eating and EAH (ps < 0.01). While reward-based eating was also positively associated with weight status (p < 0.01), this association was moderated by food switching (p < 0.01) such that the relationship was stronger for children who switch more frequently (p < 0.01). CONCLUSIONS Frequent switching between foods was positively associated with EAH intake and mediated the relationship between reward-based eating and EAH. Moreover, reward-based eating was more strongly related to weight status in children who switched more frequently. Thus, food switching may contribute to overconsumption and be an important behavioral indicator of increased obesity risk in children. Studies across multiple meals and contexts will help determine if switching is a reliable behavioral phenotype.

Exploring the Longitudinal Stability of Food Neophilia and Dietary Quality and Their Prospective Relationship in Older Adults: A Cross-Lagged Panel Analysis. Nutrients 2023; 15:nu15051248.

Abstract
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.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:3815. [PMID: 36900824 PMCID: PMC10001834 DOI: 10.3390/ijerph20053815] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 02/10/2023] [Accepted: 02/15/2023] [Indexed: 06/18/2023]
Abstract
To conduct rational hunting management, a certain number of wild animals must be harvested yearly. However, some countries have a problem with managing the harvested meat. An example is Poland, where game consumption is estimated at 0.08 kg/person/year. This situation leads to environmental pollution as a result of meat exports. The level of environmental pollution depends on the type of transport and distance. However, the use of meat in the country of harvesting would generate less pollution than its export. Three constructs were used in the study, which aimed to determine whether the respondents show food neophobia, whether they are willing to seek diversity in food, and what their attitudes towards game meat are. All the scales used were previously validated. Four-hundred and fifty-three questionnaires were collected using the PAPI method. It was found that the respondents showed ambivalent attitudes towards game meat to the greatest extent (76.6%), 16.34% had positive attitudes, and 7.06% had negative attitudes. It seems essential that most of the respondents were highly inclined to look for variety in food (55.85%). Regarding food neophobia, there were 51.43% of people with medium neophobia, while also many people with a low level of neophobia-43.05%. Such results allow speculation that the respondents are open to the new food, they are looking for it, and the low level of game meat consumption is primarily due to the lack of knowledge and awareness about the value of this meat.

Abstract
Entomophagy - the consumption of insects - is often rejected by Western society despite its benefits over traditional animal-based proteins. While several factors have been identified as potential predictors of people's willingness to try insect foods, this study introduced an under-explored factor: curiosity, which is a powerful motivator of behaviour that can overcome negative emotions and motivate us to seek new experiences. In two experiments (Ns = 240 and 248), participants (all UK residents, 99.6% British citizens) rated a number of food dishes, half of which contained insects, on a number of factors including curiosity and willingness to try the dish. Across both studies, curiosity predicted willingness to try both insect and non-insect foods above and beyond other factors. Furthermore, we unexpectedly (but consistently) observed a "curiosity-boosting effect" in which curiosity positively interacted with other predictors, increasing their effect on willingness to try insect foods, but not familiar foods. These findings suggest that curiosity promotes the willingness to try insect food in two different manners: A direct effect (above and beyond other factors) and a boosting effect.

Free word association perceptions of red meats; beef is 'yummy', bison is 'lean game meat', horse is 'off limits'. Food Res Int 2021; 148:110608.

Abstract
Reduced consumption of conventional red meats due to environmental and health concerns may create interest in less familiar red meats from alternative animal species. The objective of this study was to identify perceptions of three red meats; beef, a familiar meat, and bison and horse meat, less familiar red meat alternatives. A total of 145 western Canadian participants completed an on-line survey that included a free word association task, food variety seeking and food involvement scales, and meat consumption and demographic questions. The free word association yielded 41 word categories of diverging perceptions of the 3 meats. Beef was described with positive sensory attributes and well-liked foods, yet with environmental, ethical and production concerns, reflecting the 'meat eaters' paradox'. Bison was perceived as a lean game meat, suggesting a lack of awareness of current bison production and retail availability. Horse meat was unfamiliar to 80% of the participants. Horse meat was acknowledged to be consumed in other regions, however as a companion animal and pet, the dominant perception of horse meat was that it was unacceptable for eating. Participants were clustered into four groups based on the combined food-related personality traits of variety seeking and food involvement. The high food involvement cluster associated bison with positive eating quality attributes and may be amenable to its consumption when provided with accurate information about bison production.

Abstract
Food neophobia is the fear or loathing of novel food, which may result in the rejection of the unfamiliar food item. The most frequently used and most reliable tool to measure adult food neophobia is the Food Neophobia Scale (FNS), which has been translated into several languages, making it possible to compare food neophobia levels around the world. The main objective of this research has been the adaptation and validation of the FNS in Hungary. In order to achieve the research objectives, a questionnaire survey was conducted on a representative sample of 500 adults; and, primarily, multivariate statistical tools were used. We found that despite the Hungarian population’s strong neophobic tendency, neophobia and neophilia are present at the same time. We identified two distinctive factors in the course of the exploratory factor analysis (“Willingness and trust” and “Rejection and particularity”), which distinctly separate the negatively and positively worded (reversed) FNS items. Based on these factors, four clusters were identified. Those belonging in the group of adventurous open-minded individuals constitute an ideal target group for the manufacturers of novel food items as well as products with unusual flavors, especially if those products also have health-enhancing and eco-friendly qualities.

Abstract
Consumers’ personality traits are key factors in understanding consumers’ choice and acceptance for health innovations in food products, in particular, food neophobia (FN). The patty product as a traditional pork product (TPP) with two innovative traditional pork products (ITPP) from the untapped pig breed (Porc Negre Mallorquí) in Spain were analysed. Patties were enriched with Porcini (Boletus edulis) using the claim “enriched with a natural source of dietary fiber Beta glucans that may contribute to improve our defence system” (ITPP1) and enriched with blueberries (Vaccinium corymbosum) using the claim “enriched with a natural source of antioxidant that may help to prevent cardiovascular diseases” (ITPP2). Two non-hypothetical discrete choice experiments were applied to investigate the importance of FN in consumers’ purchase intention (PI) and willingness to pay (WTP) before and after tasting the products. Results showed that the TPP and the ITPP2 received higher than expected PI and WTP. However, after tasting the products, consumers exhibited lower WTP for all ITPP showing the prevalence of the sensory experience on health innovation. The FN was highly related to WTP before the hedonic evaluation. However, it turned out to be non-significant, showing a homogenising role of the sensory experience in reducing the FN impact.
