A review of instruments developed to measure food neophobia

Cross-Cultural Analysis of Consumers' Avoidance of Snack Food Ingredients Across 13 Countries Using Check-All-That-Apply (CATA) Method

Snack foods are increasingly important because of irregular eating patterns in busy lives. Many consumers state that reading ingredients is important to them making rational choices when consuming snacks. This study investigates consumer's reported avoidance of a wide range of 20 current and potential snack food ingredients. A survey of approximately 630 consumers in each of 13 countries was conducted using a Check-All-That-Apply (CATA) method. Cochran's Q test was performed to compare percentages of avoidance among countries, and correspondence analysis and cluster analysis were conducted to visualize the similarity of avoidance tendency among countries. Results showed a high tendency to avoid insect powder, SAPP, and BHA, perhaps because of connotations such as disgust or their "non-natural" connotations. The aversion rates for soybean, corn, wheat flour, and pea flour were low. Significant differences (p < 0.05) between countries were found for all 20 ingredients. The countries were grouped into seven clusters based on similar avoidance tendencies. This research offers insights into consumer perceptions of snack food ingredients, helping manufacturers understand ingredient avoidance across cultures. These findings support tailored product strategies to enhance food safety policies. Ultimately, the study contributes valuable data for global marketing strategies and promotes innovation in response to health-conscious consumer trends.

Consumer attitudes, willingness to pay and hedonic evaluations of innovative legume gnocchi products

BACKGROUND

With growing concerns over the adverse effects of animal-derived products on health, animal welfare and the environment, the rising popularity of plant-based foods underscores the importance of understanding consumer preferences and determining acceptance. The present study takes the form of a case study that utilized innovative legume-based flours to develop multiple gnocchi products. The Becker-DeGroot-Marschak (BDM) mechanism as an auction method was employed to elicit consumers' willingness to pay (WTP) following a hedonic evaluation test involving 127 Spanish consumers.

RESULTS

The findings indicate that a majority of consumers exhibit a high level of environmental concern, coupled with increased trust in, as well as perceptions of, the benefits of consuming plant-based products. However, they demonstrated moderate attitudes with regard to plant-based products. Notably, product sample tasting had a negative impact on consumers' WTP for legume-based gnocchi. The respondents' education level, income, financial situation, government support, environmental concerns, perceived risks, flavor and color significantly influenced consumers' WTP.

CONCLUSION

The present study offers initial insights into consumer attitudes and WTP for legume-based products in Spain. The findings are of relevance for producers and marketers aiming to promote environmentally-sustainable food production and consumption. They may also play a pivotal role in facilitating the successful introduction and sale of such plant-based products in the Spanish market. Going forward, addressing any limitations of this study and exploring further research avenues will be crucial for refining our understanding of consumer behavior in this context. © 2024 The Author(s).

Consumers' familiarity level shapes motives and contexts for preparing and consuming dishes

Consumers' familiarity with foods influences their expectations and experiences upon consumption. Familiarity has mostly been assessed using perceived familiarity when studying single foods. However, foods are often combined to create dishes, complex compositions eaten at various mealtimes. Hence, this paper aimed to study if and how the level of consumers' dish familiarity shapes their motives and preferred contexts for home cooking and consuming three dishes: one traditional dish, one adopted ethnic dish, and one mainly unavailable and unknown ethnic dish. First, we describe the operationalization of familiarity into the qualitative "consumer's dish familiarity index" (CDFI) used to determine participants' familiarity level to the dishes. CDFI includes four indicators (perceived availability, consumer's knowledge, preparation, and consumption). In-depth interviews (n = 27) were conducted with Dutch and Chilean women, as the countries have contrasting levels of immigration and globalization, which are expected to shape their inhabitants' familiarity level with ethnic dishes. Most experienced consumers (high familiarity) mentioned more dishes and individual-related motives to prepare and consume a traditional or an adopted ethnic dish. Social- and individual-related motives were salient when a dish was unknown and/or not previously consumed. Consumers' familiarity level also guided their preferred social context and location when consuming the dishes. A dish barely available will likely be first consumed in a restaurant to try a new dish that is perceived as appetizing to eat. Results showed that convenience, wanting to eat comfort foods, and showing affection to others are important motivators to facilitate the adoption of dishes to be home cooked. PRACTICAL APPLICATION: This paper provides a novel approach to assess consumer familiarity to dishes. The qualitative consumer's dish familiarity index (CDFI) can be used in future investigations to assess and classify consumers into different dish familiarity levels by using four indicators. The outcomes of this study suggest consumers' familiarity level could serve as a reference for designing and/or improving (ethnic) foods and creating marketing campaigns to introduce them into (foreign) countries.

Olfactory performance and odor liking are negatively associated with food neophobia in children aged between 3 and 9 years

BACKGROUND

Child food neophobia, i.e., rejection or avoidance of novel foods at a young age, is a prevalent nutrition problem that affects the quality of children's diet and impedes the development of healthy food preferences. Sensory sensitivity can relate to the degree of food neophobia, but previous studies rarely focused on the olfactory component of this problem in children.

OBJECTIVE

We aimed to thoroughly examine the relationship between various aspects of olfactory sensitivity and food neophobia in children.

METHODS

246 children aged between three and nine years took part in a food neophobia assessment as well as in a comprehensive, psychophysical olfactory testing.

RESULTS

We found that certain smell perception aspects such as lower odor liking, poorer odor identification ability as well as lower sensitivity to an unknown non-food odor all significantly predicted higher food neophobia in children. Among individual characteristics of either a child or a caregiver, only the child's age significantly and positively predicted food neophobia. The exploratory model looking into the role of family environment factors predicting self-reported food neophobia in children revealed that food neophobia was associated with lower control given to a child in this child's feeding process, as well as with a more frequent use of food as a reward in feeding.

CONCLUSIONS

We suggest that suppressed olfactory perception and performance can play a unique role in child nutritional difficulties. The study inspires further considerations of olfaction-engaging interventions to counteract food-neophobia in children.

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 Neophobia in Children: A Case Study in Federal District/Brazil

A reluctance to eat and/or avoidance of novel foods is characterized as food neophobia (FN). FN restricts the diet to familiar foods when, in fact, it should be much more varied. FN can be a barrier to healthy foods, affecting the quality of diet, and impairing children's growth and development. Therefore, according to their caregivers' perceptions, this study aimed to evaluate FN in children from Federal District/Brazil. The Brazilian Children's Food Neophobia Questionnaire (BCFNeo), a specific instrument developed and validated in Brazil, was answered by caregivers of children aged 4 to 11 y/o. Sampling occurred through snowball recruitment, being convenient and non-probabilistic. The Health Sciences Ethics Committee approved the study. The analysis evaluated FN in total (BCFNeoTot) and in the following domains: general (FNgen), for fruits (FNfru), and for vegetables (FNveg). FN scores were compared between sex and child's age and categorized according to three ordinal levels. FN levels were compared using the Mann-Whitney U test. The Friedman test, followed by the Wilcoxon test with Bonferroni correction, was performed to analyze differences in FN according to the environment. Of the caregivers' answers for their children, 595 answers were included, because 19 were out of age. The prevalence of high FN was 42.9%. The domain with the highest prevalence of high FN was vegetables (48.6%). Children aged 8 to 11 y/o had a higher mean FN in two domains (FNgen p = 0.047 and FNveg p = 0.038) when compared to children aged 4 to 7 y/o. Boys were more neophobic in all domains (FNgen p = 0.017; FNfru p = 0.010; FNveg p = 0.013; BCFNeoTot p = 0.008), and FN tends not to decrease with age. The results showed that the children of the FD are more neophobic than Brazilian children in general, highlighting the importance of additional studies in FN determinants in this population and nutritional education interventions to reduce FN among FD children.

Food Neophobia and Avoidant/Restrictive Food Intake among Adults and Related Factors

Avoidant/restrictive food intake disorder (ARFID) includes age-inappropriate feeding behaviors in eating patterns, including food neophobia, defined as refusal or reluctance to eat new or unknown foods. This study aimed to assess the prevalence of ARFID and food neophobia among adults and determine the related characteristics of these risks. The study used an anonymous survey questionnaire consisting of three parts as the research tool. The first part of the questionnaire was a metric and concerned socio-demographic data. The Food Neophobia Scale (FNS) and the Nine-Item Avoidance/Restrictive Food Disorder Screen Questionnaire (NIAS) were used to evaluate the eating disorders. The survey included 309 people (60.2% women, 39.8% men) aged 18-77 years. NIAS results indicated that 15.2% of the subjects showed food selectivity, and 11.0% had food anxiety. In the FNS assessment, 42.4% had a low risk of food neophobia, 38.2% a medium risk, and 19.4% a high risk. A higher risk of food neophobia correlated with higher NIAS scores, indicating a higher risk of ARFID (p = 0.00231). The NIAS score increased with the risk of food neophobia (p = 0.000). Respondents at low risk of neophobia were most likely to avoid several products (83.97%), while in the high-risk group, 56.67% did not want to eat a favorite food enriched with a new ingredient. A higher risk of neophobia was correlated with more food avoidance and adverse reactions to new foods (p = 0.000). A higher risk of food neophobia is strongly correlated with a higher risk of ARFID. Although demographics did not significantly impact NIAS results, some trends were noted, such as higher scores among older and underweight people. Those with a higher risk of food neophobia show more food avoidance and a greater reluctance to experiment with new ingredients. Public education should emphasize that eating disorders affect both sexes equally, with tailored interventions for high-risk groups such as the elderly, rural populations, and those with lower education. Health policies should promote access to nutrition education, psychological support, and diverse food options, while further research is needed to improve targeted interventions.

Novel misos shape distinct microbial ecologies: opportunities for flavourful sustainable food innovation

Fermentation is resurgent around the world as people seek healthier, more sustainable, and tasty food options. This study explores the microbial ecology of miso, a traditional Japanese fermented paste, made with novel regional substrates to develop new plant-based foods. Eight novel miso varieties were developed using different protein-rich substrates: yellow peas, Gotland lentils, and fava beans (each with two treatments: standard and nixtamalisation), as well as rye bread and soybeans. The misos were produced at Noma, a restaurant in Copenhagen, Denmark. Samples were analysed with biological and technical triplicates at the beginning and end of fermentation. We also incorporated in this study six samples of novel misos produced following the same recipe at Inua, a former affiliate restaurant of Noma in Tokyo, Japan. To analyse microbial community structure and diversity, metabarcoding (16S and ITS) and shotgun metagenomic analyses were performed. The misos contain a greater range of microbes than is currently described for miso in the literature. The composition of the novel yellow pea misos was notably similar to the traditional soybean ones, suggesting they are a good alternative, which supports our culinary collaborators' sensory conclusions. For bacteria, we found that overall substrate had the strongest effect, followed by time, treatment (nixtamalisation), and geography. For fungi, there was a slightly stronger effect of geography and a mild effect of substrate, and no significant effects for treatment or time. Based on an analysis of metagenome-assembled genomes (MAGs), strains of Staphylococccus epidermidis differentiated according to substrate. Carotenoid biosynthesis genes in these MAGs appeared in strains from Japan but not from Denmark, suggesting a possible gene-level geographical effect. The benign and possibly functional presence of S. epidermidis in these misos, a species typically associated with the human skin microbiome, suggests possible adaptation to the miso niche, and the flow of microbes between bodies and foods in certain fermentation as more common than is currently recognised. This study improves our understanding of miso ecology, highlights the potential for developing novel misos using diverse local ingredients, and suggests how fermentation innovation can contribute to studies of microbial ecology and evolution.

Personalized nutrition with 3D-printed foods: A systematic review on the impact of different additives

Three-dimensional (3D) printing is one of the world's top novel technologies in the food industry due to the production of food in different conditions and places (restaurants, homes, catering, schools, for dysphagia patients, and astronauts' food) and the production of personalized food. Nowadays, 3D printers are used in the main food industries, including meat, dairy, cereals, fruits, and vegetables, and have been able to produce successfully on a small scale. However, due to the expansion of this technology, it has challenges such as high-scale production, selection of printable food, formulation optimization, and food production according to the consumer's opinion. Food additives (gums, enzymes, proteins, starches, polyphenols, spices, probiotics, algae, edible insects, oils, salts, vitamins, flavors, and by-products) are one of the main components of the formulation that can be effective in food production according to the consumer's attitude. Food additives can have the highest impact on textural and sensory characteristics, which can be effective in improving consumer attitudes and reducing food neophobia. Most of the 3D-printed food cannot be printed without the presence of hydrocolloids, because the proper flow of the selected formulation is one of the key factors in improving the quality of the printed product. Functional additives such as probiotics can be useful for specific purposes and functional food production. Food personalization for specific diseases with 3D printing technology requires a change in the formulation, which is closely related to the selection of correct food additives. For example, the production of 3D-printed plant-based steaks is not possible without the presence of additives, or the production of food for dysphagia patients is possible in many cases by adding hydrocolloids. In general, additives can improve the textural, rheological, nutritional, and sensory characteristics of 3D printed foods; so, investigating the mechanism of the additives on all the characteristics of the printed product can provide a wide perspective for industrial production and future studies.

Exploring Adult Eating Behaviors and Food Neophobia: A National Study in Romania

Food neophobia involves avoiding new foods due to reluctance, aversion, or disgust. The Food Neophobia Scale (FNS) is the most reliable and common adult food neophobia test. It helps compare food neophobia across cultures by being translated into numerous languages. This study adapted, translated, and validated the FNS for Romania. This translated version was piloted in November 2023 on 59 students in the medical field from two distinct Romanian cities. Between December 2023 and February 2024, 375 adults were surveyed, representing Romania's population within a 90% confidence interval. The average age of responders was 38.07 years, with a standard deviation of 10.75 and a 4:1 female-to-male sex ratio. The Cronbach's alpha test was used to validate the questionnaire. Our study found that the mean FNS value was 31.86; most Romanian respondents (69.20%) were neutral towards trying new foods, with a significant portion being neophobes (18.21%) outnumbering neophiles (12.59%). When compared to international study results, Romanian adults, on average, exhibited a higher percentage of neophobes compared to those in Korea (13%), Hungary (16.8%), Italy (17%), and Brazil (17.5%), but a lower percentage than those in Lebanon (21.5%). The findings indicate that the translated scale can be utilized to assess neophobia among Romanian speakers.

Cross-Cultural Adaptation and Validation of the Malay-Translated Version of the Food Neophobia Scale for Malaysian Young Adults

The Food Neophobia Scale (FNS) is a research instrument, originally developed in English, to assess an individual's level of food neophobia. However, it has not yet been translated and validated for Malaysians. Therefore, we aimed to translate and validate a Malay-translated version of the FNS. Respondents were 200 young adults (mostly females, 73%; and students, 82.0%; M age = 22.3 years, SD = 2.3). We first translated the FNS into Malay using the forward-backward translation method, and a panel of nutrition and dietetics experts then reviewed it for item relevance, clarity, simplicity, and ambiguity. The translated FNS suggested good content validity with an item-level content validity index (I-CVI) > .8, a scale-level content validity index (S-CVI)/average = .8 and a S-CVI/universal agreement = .96. Principal component analysis revealed a two-factor model: (i) willingness and trust; and (ii) rejection and fear. Cronbach's alpha for the Malay-translated FNS was .808, demonstrating high internal consistency and reliability among young Malaysian adults. Future investigators can now use this Malay-translated FNS instrument to determine levels of food neophobia among Malaysians.

Food neophobia and its association with dietary choices and willingness to eat insects

Growing populations, changing dietary preferences and limitations on natural resources have meant that finding an alternative to traditional animal-based protein sources is a priority. Insects have been proposed as a possible solution due to their many benefits including low resource inputs and rich nutritional profile. However, insects are not consumed on a large scale by Australians. Food neophobia (reluctance to try new foods) could be contributing to this delay and as such, this study aimed to explore the role of food neophobia on protein food source habits and willingness to eat insects as food. A total of 601 participants (76.2% female, 23.8% male) completed an online survey which included a questionnaire measuring food neophobia status, participants' self-reported usual protein dietary habits, their previous insect-eating experience, future willingness to eat insects, and potential motivations to include insects in their diet. Results indicated a strong association between food neophobia and participants' dietary choices such as following a vegan or vegetarian diet (p = 0.024). In addition, food neophobia was correlated with a reduced likelihood of previous insect-eating experience (p < 0.001), as well as a decreased willingness to eat insects in the future (p < 0.001). This study provides a greater understanding of the role of food neophobia status and dietary choices in consumers' willingness to eat insects and identifies possible motivating factors that may increase the likelihood of consumers' future insect eating.

A review on children's oral texture perception and preferences in foods

Texture properties of foods are particular drivers for food acceptance and rejection in children. The texture preferences follow the developmental progression of the child and these changes modulate the present and future food habits. This paper reviews the development and factors influencing texture preferences in children and the methods in food texture research with children. The child's acceptance of more complex food textures is age-dependent. The progression is indorsed by the development of oral processing skills at an early age and bolstered by repeated exposures to foods with varying textures. Children generally reject foods containing pieces or bits (i.e., geometrical textural properties); however, the impact of mechanical textural properties on food acceptance is less clear. Child characteristics such as food neophobia, picky eating, and tactile over-responsivity, negatively affect the acceptance of more diverse food textures. Depending on the child's age, the prevailing methods of characterizing food texture preferences in children include observational techniques and self-reported questionnaires. Despite knowledge of children's development of masticatory skills, learning, and cognitive abilities, the relationships of these changes to food texture acceptance and the recommended test methodology for evaluating product texture acceptance in this period of life are still limited.

A gender approach to wine innovation and organic wine preferences

The development of innovative products, such as novel wines, is rejected by certain consumers that value attributes that may conflict with innovation. This is the case of the organic production label. The present study examined the impact of gender on wine purchasing preferences for innovative and organic wines. The findings showed that price is the most important attribute for both men and women when buying wine. The results also revealed that women assign greater importance to the production system (organic/conventional) than men. The segmentation generated according to the level of wine neophobia revealed significant differences between men and women in the frequency of wine consumption and the socioeconomic variables considered (age, educational level and income). The level of wine neophobia was higher in women than in men, but, in both genders, it increased with age and decreased as income and educational level increased. Women’s lesser interest in innovative wines and their more positive attitude towards organic wines encourages the consideration of women as a segment in which tradition and naturalness related to wine should be specifically taking into account.

The Impact of Alternative Foods on Consumers' Continuance Intention from an Innovation Perspective

This paper aims to model consumers’ perceptions and preferences toward alternative foods. We conducted a survey of 519 people and analyzed their responses using a structural equation model. The article discusses the role of food innovation quality (FIQ), a concept developed from innovative design, which shows how consumers perceive the quality of products in an innovative context. Further, the paper discusses the relationship between this concept and promoting consumer acceptance of alternative foods. Studies suggest that higher FIQ may lead to increased consumer satisfaction with alternative foods, which may in turn lead to higher levels of trust and continuation. Moreover, expectations play a significant role in FIQ and in the perceived value of alternative foods in the model. This illustrates that the promotion of alternative foods in an innovative manner should include establishing a practical mechanism for meeting consumer expectations. Given the continued growth in global food demand, it is both effective and beneficial to promote alternative foods through innovative design as part of a broader food industry approach. On the one hand, alternative foods produced in an innovative manner serve to energize the consumer market by expanding dietary choices. On the other hand, alternative foods, which include new forms of meat products, contribute to the alleviation of the problem of meat production capacity in agriculture. In addition, the alternative foods process eliminates the emission of large amounts of carbon dioxide by traditional agriculture, increasing the sustainability of food production.

It's not just about the food: Motivators of food patterns and their link with sustainable food neophobia

Food sustainability has been a growing focus in an attempt to limit climate change; as a result, the sustainable food market and an onset of social behaviors, such as shopping local and eating plant-based, is increasing. Limited however, is the understanding of how these sustainable food options are perceived among individuals who have different motivations for eating the way that they do. The situated identity enactment model and food neophobia literature are used to conceptualize the development of a model outlining how physical health, culture, and sustainability driven motivations of food patterns influence one's fear of sustainable food-moving beyond attitude as a suitable measurement in this context due to the complexity in the way select situational ques are cognitively processed. Data were collected among a representative U.S sample (n = 414) and analyzed through structural equation modeling using plant-based meat as the product of focus. Individuals whose food choices are culturally driven showed greater sustainable food neophobia and as motivations were more sustainability driven, the less fear they had of such foods. Contrary to what existing literature suggests, those driven by physical health showed no significance in the effects of their food patterns on neophobia even when considering a food option often positioned as healthier. Results also provided evidence of high local identity being a positive predictor of neophobia among those whose choices were culturally and sustainably driven. This study highlights the sensitivity of sustainable food and the importance of considering context, norms, and identity on food behaviors, regardless of one's underlying motives for food choices. Findings are influential in advancing social psychology literature on food behaviors and encourages the use of the model on other sustainable food products.

Food Neophobia among Brazilian Children: Prevalence and Questionnaire Score Development

This study aims to create and validate a score to classify food neophobia among Brazilian children (from the ages of 4 to 11 years) and investigate the prevalence of food neophobia. This descriptive cross-sectional population-based study is conducted following three steps: (i) the application of an instrument to identify food neophobia in Brazilian children by their caregivers; (ii) the instrument’s score definition; and (iii) the evaluation and characterization of the national prevalence of food neophobia among Brazilian children. The scores were categorized into three levels, based on the tertial approximation: low, moderate, and high. The study had 1112 participants, and the prevalence of high food neophobia was observed in 33.4% of Brazilian children. The prevalence of food neophobia allowed us to identify this behavior in Brazilian children and better understand the population. Boys were significantly more neophobic than girls. The general neophobia score and domains did not significantly differ between Brazilian regions and age groups. It is worrying that food neophobia did not decrease with advancing age. The score for the complete instrument with 25 items, or the 3 domains, makes its use practical. It can be used to assess neophobia with more caution, evaluate the most neophobic children, and enable more targeted professional interventions to promote healthier and sustainable eating habits.

To fear the unknown: Covid-19 confinement, fear, and food choice

The coronavirus outbreak in December 2019 completely changed the dynamic of consumption in different sectors of industry. The food and beverage industries have been profoundly affected, from production, to modifications in consumers' choices. Among the different reasons behind those modifications is confinement, which forces consumers to stay at home for an extended period and just go out to perform essential tasks, such as going to the supermarket. We hypothesized that this new dynamic of consumption could create a situation of fear that changes food choice. To test this hypothesis, two studies were conducted in three countries with a different degree of confinement: Mexico (flexible), Spain (strict), and Peru (hard). Study one consisted of a free association task with 60 participants in each country with the inductor word "coronavirus and food". The different associations served as the basis to build a structured questionnaire, which was used in the second study focused on fear and food choice. The second study was applied to 450 participants in the same three countries. Results showed that fear can be separated into nine dimensions: social, emotional, food supply, government, basic needs, food-delivery, overeating, immunity, and family conflicts. The participants could also be clustered into four different groups that differ in their country of origin and sex, but also in their food choice. Overall, the results showed that fear influenced consumer's food choices during a confinement period.

Food Texture Acceptance, Sensory Sensitivity, and Food Neophobia in Children and Their Parents

This study aims to explore whether children's food texture preferences are associated with different levels of sensory sensitivity and food neophobia, as well as with other variables, such as parental texture preferences. An online questionnaire was completed by 70 children aged 6-13 years old, alongside one of their parents. Generic texture preferences of children and parents were investigated with the Child Food Texture Preference Questionnaire (CFTPQ). Parents provided background information about their children by completing the Food Neophobia Scale (FNS), the Short Sensory Profile (SSP) and a Food Frequency Questionnaire (FFQ). The results showed that children who differed in their texture-liker status also differed in their levels of food neophobia and sensory information processing: children who preferred softer and non-particulate versions of foods were found to be more neophobic and sensory sensitive across all sensory domains. No relationship was found between parental and children's texture preferences.

The Use of Demographics and Psychographics to Study Product Effects with Nutrient Supplements: Exploratory Multi-Country Data

Demographics and psychographics are used to study the influence of different consumers on product effects in food development and testing. Demographics have a longer history and are routinely used in most research; psychographics are more recent, raising the question of whether they add to research on food products. The research presented here represents extensive exploratory data that demonstrate that both demographic measures and psychographic measures add to our understanding of consumer's liking ratings for nutrient supplements. The results are discussed in the context of broader research on a range of food products. In addition, the research reported here was conducted in four different countries, demonstrating many country effects. Finally, tests were conducted with users of the products, lapsed users of the product, and users of other nutrient supplements (non-users), and this led to many differences in product testing. These results further suggest that age and gender are not the only demographic variables to be studied, along with psychographic variables. The psychographic variables should be selected for a particular product category under investigation, as effects of specific psychographic measures vary for product categories. Specific variables do not fit all products for both demographics and psychographics.

Filthy fruit! Confirmation bias and novel food

Fruit and vegetable consumption is worldwide too low, resulting in poor diet quality and health-related problems. A cognitive factor that might contribute to this low consumption is confirmation bias. Confirmation bias has been established in anxiety research and comprises the tendency to search for reinforcing negative information, while ignoring counter attitudinal information. If applicable to food, asking for negative food information reinforces the negative attitude and decreases the willingness to try (novel) food. The aim of the current study was twofold. First, to examine if confirmation bias translates to food stimuli. Second, to investigate if this bias is exaggerated in persons with higher levels of food neophobia. To this end, 117 participants (age M = 21.45, SD = 4.48) carried out an online study. They filled in the food neophobia scale (FNS) and performed a search for additional information scale (SAIS) task. Four novel fruits were used, two looking tasteful (pomelo and rose apple) and two looking non-tasteful (black sapote and noni fruit). Participants rated their willingness to eat these fruits and subsequently could indicate how eager they were to receive positive or negative information regarding that fruit. The results indicated that the participants were more willing to try the tasteful looking fruits than the non-tasteful. Additionally, higher levels of food neophobia coincided with less willingness to eat all fruits. Confirmation bias was observed, more negative information was requested for the non-tasteful than for the tasteful fruits. This bias was not related to levels of food neophobia. These results are important as confirmation bias might make people even more negative towards novel foods and could contribute to even less fruit and vegetable consumption, especially when they look less appetizing.

Exploring how product descriptors and packaging colors impact consumers' perceptions of plant-based meat alternative products

While consumers have been increasingly trying to reduce their meat consumption due to rising concerns about its impact on their health and the environment, many still find animal-based foods more attractive than plant-based foods, thus hindering their adoption. Could marketing cues such as product descriptors and packaging colors help make these products more attractive to consumers? Across two studies, we tested the effects of product descriptors and packaging colors on meat eating consumers' perceptions of, and behavioral intentions toward, plant-based meat alternative products. Study 1 revealed that a "plant-based" (vs. "meat alternative") descriptor positively impacted perceptions of healthiness and eco-friendliness, as well as trial likelihood, and negatively impacted predicted quantity consumed. Study 2 provided some evidence for the moderating role of packaging color, and more specifically for the (mis)matching effects of product descriptor and packaging color on product perceptions and behavioral intentions. Results revealed that, when using a "meat alternative" descriptor, mismatching (vs. matching) it with a green (vs. red) packaging color negatively impacted perceptions of eco-friendliness and trial likelihood. Conversely, when using a "plant-based" descriptor, matching (vs. mismatching) it with a green (vs. red) packaging color negatively impacted predicted satiety. Overall, our research suggests that marketing cues can, to some extent, impact consumers' perceptions of plant-based meat alternative products and related behavioral intentions, and offers many avenues for future research.

Food neophobia among Nigerian consumers: a study on attitudes towards novel turmeric-fortified drinks

BACKGROUND

Knowledge on food neophobia among African consumers is scarce. Yet a good understanding in this area is essential to support the acceptance of new foods, for instance, when fortifying familiar foods to improve the health and nutritional status of the populace. In this paper, food neophobia among Nigerian consumers was assessed by their attitudes towards unfamiliar beverages, namely turmeric-fortified drinks. Turmeric was chosen as the Nigerian government is stimulating its production for income generation, but the spice is not commonly used in Nigerian foods and drinks.

RESULTS

Familiar street-vended drinks, i.e. soymilk and the hibiscus-based drink zobo, were fortified with turmeric. Respondents (483) were allowed to try both the familiar and unfamiliar (turmeric-fortified) drinks. Subjects also filled in a 20-item questionnaire concerning attitudes toward food and eating. Food neophobia was measured by the Food Attitude Survey (FAS) instrument ratings. Using the FAS, people who reported liking the fortified drinks ('likers') were compared with those who disliked the drinks ('dislikers') and those who were unwilling to try the drinks ('will not tryers'). Males were found to be more food neophobic than females. Middle-class income earners, the age group of 26-35 years and respondents with the highest education levels also showed a more food neophobic attitude towards turmeric-fortified drinks.

CONCLUSION

Practical insights are given regarding the introduction of novel foods to Nigerian consumers by paying attention to attitudes from respondents with different demographic characteristics. The use of influencers seems to be a promising approach to address food neophobia in Nigeria. © 2020 The Authors.

Appetite self-regulation declines across childhood while general self-regulation improves: A narrative review of the origins and development of appetite self-regulation

This narrative review discusses the origins and development of appetite self-regulation (ASR) in childhood (from infancy to age 6 or 7 years). The origins, or foundations, are the biological infrastructure associated with appetite regulation and appetite self-regulation. Homeostatic regulation in infancy is examined and then evidence about developmental change in components of ASR. The main ASR-related components covered are: delay-of-gratification, caloric compensation, eating in the absence of hunger, food responsiveness/hedonics and fussy eating. The research included behavioral measures, parent-reports of appetitive traits and fMRI studies. There were two main trends in the evidence: a decline across childhood in the components of ASR associated with food approach (and therefore an increase in disinhibited eating), and wide individual differences. The decline in ASR contrasts with general self-regulation (GSR) where the evidence is of an improvement across childhood. For many children, bottom-up automatic reactive processes via food reward/hedonics or food avoidance as in fussy eating, appear not to be matched by improvements in top-down regulatory capacities. The prominence of bottom-up processes in ASR could be the main factor in possible differences in developmental paths for GSR and ASR. GSR research is situated in developmental science with its focus on developmental processes, theory and methodology. In contrast, the development of ASR at present does not have a strong developmental tradition to access and there is no unifying model of ASR and its development. We concluded (1) outside of mean-level or normative changes in the components of ASR, individual differences are prominent, and (2) there is a need to formulate models of developmental change in ASR together with appropriate measurement, research designs and data analysis strategies.

Preferences of German Consumers for Meat Products Blended with Plant-Based Proteins

High levels of meat consumption are increasingly being criticised for ethical, environmental, and social reasons. Plant-based meat substitutes have been with reservations identified as healthy sources of protein in comparison to meat. This alternative offers several social, environmental, and probably health benefits, and it may play a role in reducing meat consumption. However, there has been a lack of research on how specific meat substitute attributes can influence consumers to replace or partially replace meat in their diets. Research has demonstrated that, in many countries, consumers are highly attached to meat. They consider it to be an essential and integral element of their daily diet. For the consumers that are not interested in vegan or vegetarian alternatives to meat, so-called meathybrids could be a low-threshold option for a more sustainable food consumption behaviour. In meathybrids, only a fraction of the meat product (e.g., 20% to 50%) is replaced with plant-based proteins. In this paper, the results of an online survey with 500 German consumers are presented with a focus on preferences and attitudes relating to meathyrids. The results show that more than fifty percent of consumers substitute meat at least occasionally. Thus, approximately half of the respondents reveal an eligible consumption behaviour with respect to sustainability and healthiness to a certain degree. Regarding the determinants of choosing either meathybrid or meat, it becomes evident that the highest effect is exerted by the health perception. The healthier meathybrids are perceived, the higher is the choice probability. Thus, this egoistic motive seems to outperform altruistic motives, like animal welfare or environmental concerns, when it comes to choice for this new product category.

Importance of food choice motives vary with degree of food neophobia

Food Neophobia (FN) is a stable trait that measures individuals' propensity to avoid novel/unfamiliar foods. In this research, focus was directed to covariation between FN and food choice factors as measured using two variants of the food choice questionnaire (FCQ). To our knowledge, there are no previous studies which investigates these associations in detail, and in this regard the present research advances understanding of individual differences in FN and FCQ. Existing survey data were used, collected in the USA and Australia with ~1500 and ~750 consumers, respectively. Data from New Zealand came from studies conducted at central location test (CLT) facilities (Ñ400, Ñ1100). There were many consistencies in results across the four studies, and this was noteworthy considering that the data were obtained in 3 different countries across more than 10 years and with participants in CLT and online studies. The FCQ factor Familiarity always gained in importance with increasing FN. The FCQ factor Convenience also always gained in importance with increasing FN, in particular importance of simplicity in preparation and cooking. Conversely, the factors Health and Natural Content decreased in importance, as did factors linked to Environmental and Social Justice concerns. Price and Sensory Appeal remained very important for daily food choices among "neophobic" and "neophilic" consumers alike, and this mirrors past studies from diverse consumer populations. The importance of Mood was low regardless of FN status. Additional research is needed to confirm that these findings generalise to consumers in other countries, and assuming they do, this work contributes to the mounting evidence of the pervasive effects of FN on consumers' food-related experiences and motivations. Determining why FN influences food choice motives is an important next step.

FACTORS ASSOCIATED WITH FOOD NEOPHOBIA IN CHILDREN: SYSTEMATIC REVIEW

Objective:

To identify the factors associated with food neophobia in children through a systematic review.

Data sources:

This research was based on the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The research was carried out in the PubMed, Science Direct, and Scientific Electronic Library Online databases, with the combination of health descriptors in English and Portuguese: (“Food Neophobia” OR “Feeding Behavior” OR “Food Preferences” OR “Food Selectivity”) AND Child, from 2000 to 2019. Studies that evaluated factors associated with food neophobia in children were included. The quality of the studies was assessed using the Effective Public Health Practice Project: Quality Assessment Tool for Quantitative Studies (QATQS).

Data synthesis:

19 studies were included in the systematic review. The prevalence of food neophobia ranged from 12.8 to 100%. The studies used three different scales to measure the level of food neophobia. The main factors associated with food neophobia were: parental influence on children’s eating habits, children’s innate preference for sweet and savory flavors, influence of the sensory aspect of the food, parents’ pressure for the child to eat, parents’ lack of encouragement and/or affection at mealtime, childhood anxiety, and diets with low variety and low nutritional quality.

Conclusions:

The factors associated with food neophobia permeate several areas of the child’s life, thus, interprofessional follow-up becomes essential in the intervention process.

Children overcoming picky eating (COPE) - A cluster randomised controlled trial

OBJECTIVES

Food neophobia limits dietary variety in children and adults. Interventions to alleviate the impact of neophobia on children's dietary variety have had varying success. The potential effectiveness of mindfulness, a process of bringing awareness to the present moment, has received little attention. This trial aimed to explore the effectiveness of two mindfulness exercises on novel food acceptance for children.

METHODS

A cluster-randomised controlled trial with three trial arms compared the impact of two mindfulness exercises (mindful breathing and mindful raisin-eating) and a non-mindful control task on anticipated liking and intake of a novel fruit. Seventy-one children aged 10-12 years engaged in one of the three tasks at school over five days and were offered a novel fruit at the end of the intervention. Children self-reported mindfulness, food neophobia and anxiety at baseline and follow-up.

RESULTS

Two mixed-effects models showed that, controlling for school effects and covariates (including mindfulness, food neophobia and anxiety), children in the mindful raisin-eating arm reported greater anticipated liking of a novel fruit and children in both mindfulness arms consumed greater amounts of a novel fruit than children in the control arm. Mixed-design ANOVAs indicated that mindfulness, food neophobia and anxiety did not change over time in each trial arm.

CONCLUSIONS

The results provide promising evidence for the potential effectiveness of mindfulness interventions in encouraging children to try new foods. The mechanisms underlying effectiveness remain unclear and further research, exploring long-term effects and the possibility to generalise these findings to other food groups such as vegetables, is needed.

Sensory Characteristics Contributing to Pleasantness of Oat Product Concepts by Finnish and Chinese Consumers

Oats are increasingly popular among consumers and the food industry. While data exist on sensory characteristics of oats as such, previous studies focusing on the pleasantness of oats, and especially investigations of a wide range of oat products by European and Asian consumers, are scarce. An online questionnaire was organized in Finland (n = 381; 83.7% Finnish) focusing on the liking and familiarity of oat products, followed by sensory tests in Finland (n = 65 and n = 73) and China (n = 103) using the Check-All-That-Apply method and hedonic ratings. A questionnaire revealed that the Finnish consumers rated the pleasantness and familiarity of several oat product categories, such as breads and porridges, higher compared to participants of other ethnicities. Sensory tests showed both similarities, e.g., porridges were described as “natural”, “healthy” and “oat-like”, and differences between countries, e.g., sweet biscuits, were described as “crispy” and “hard” by Finnish consumers and “strange” and “musty” by Chinese consumers. Sweet products were unanimously preferred. The ethnicity had an important role affecting the rating of pleasantness and familiarity of oat product categories, whereas food neophobia and health interest status also had an influence. The proved healthiness of oats was a crucial factor affecting the choices of consumers and their acceptance in both countries.

Revisiting nutrition backlash: Psychometric properties and discriminant validity of the nutrition backlash scale

OBJECTIVES

Nutrition backlash is a disposition defined by negative feelings about dietary recommendations. Past research has measured nutrition backlash using the nutrition backlash scale (NBS) and found that it is negatively related to the consumption of fruits and vegetables. The aim of this study was to examine several aspects of the NBS, including factor structure, discriminant validity, and relationship to demographic characteristics and health behaviors.

METHODS

Adults were recruited to participate in two studies. Study 1 (N = 480) included measures of nutritional backlash, information overload, worry, fatalism, and nutrition-related behaviors. Study 2 (N = 399) was a follow-up that examined the factor structure of the NBS in a separate sample.

RESULTS

In study 1, a six-item version of the NBS was found to be a good fit for the data and discriminant from overload, worry, and fatalism. NBS was higher for those with less education, non-white participants, and men. Individuals with higher backlash were less likely to look at nutritional labels and to use sunscreen. Study 2 confirmed the factor structure from study 1.

CONCLUSIONS

A six-item version of the NBS was found to be reliable, discriminant from related measures, higher in underserved groups (less-educated, non-white, and male participants), and related to nutrition label use.

Instrument to Identify Food Neophobia in Brazilian Children by Their Caregivers

This study aimed to develop a specific instrument to evaluate food neophobia focused on Brazilian children and to perform the content validation and internal semantic consistency and reproducibility evaluation of the instrument. Three steps were necessary to conduct the study: (i) development of the instrument, (ii) internal validation (content validation and semantic evaluation) of the food neophobia instrument using 22 experts in the first round and 20 of them in the second round, (iii) evaluation of the internal consistency and reproducibility of the instrument with the children’s caregivers, using the test–retest (where the same caregiver—n = 22—answered twice, with 24 h interval) and comparing responses between two caregivers (n = 44) of the same children (n = 22). We developed an instrument in Brazilian–Portuguese to evaluate children’s food neophobia based on the caregivers’ perceptions with 25 items divided into three domains (neophobia in general, neophobia for fruits and neophobia for vegetables). Our results indicated that the instrument has excellent internal consistency (>0.9) and reproducibility (>0.9) when answered by the caregiver who knows the child’s eating habits, indicating reliability to be applied in Brazil. In addition, when the two caregivers answered the instrument, we found a good reproducibility (>0.6), confirming the possibility to be answered by one of the caregivers. Further studies are necessary to complete external validation with a representative sample of the target group in Brazil, showing nationwide the profile of the population. The potential of a neophobia study would contribute to the implementation of effective strategies and guidelines to support parents and health professionals, especially those involved in health and nutrition, to identify traces of food neophobia or neophobic behavior. By accurately measuring food neophobia in children, families can prevent nutritional deficiencies throughout adolescence and adulthood, improving eating habits. Children usually have neophobias similar to the ones presented by their parents—and when early detected, these neophobias can be addressed.

Modifying the Bass diffusion model to study adoption of radical new foods-The case of edible insects in the Netherlands

Developing new food products is a complex process. Even if a company performs new product development activities successfully, it is still uncertain if consumers will adopt the product. The Bass diffusion model has often been used to study product adoption. However, existing modifications of the Bass diffusion model do not capture the complexity of consumer food choice and they have limitations in situations where there is no sales data. To avoid these challenges, the system dynamics approach can be employed. This paper aimed at extending the existing system dynamics Bass diffusion model to investigate the dynamic adoption process of insect-based food from a consumer research perspective. We performed a structured review of the literature on edible insects to build the model. The model was used to study adoption of the product amongst consumers in the Netherlands. Simulations revealed that diffusion of a radical innovation, such as an insect-based burger, can proceed for many years before there are observable adopters in the total population, under the currently reported practices in the Netherlands. Expanding awareness of this innovation requires many decades, which can be quickened by developing strategies aimed at increasing word-of-mouth. Nevertheless, the low likelihood to adopt such food remains a challenge towards full adoption, even when the sensory quality of products is improved. To fully explore how to improve the diffusion outcome of edible insects, more knowledge on mechanisms related to positive and negative word-of-mouth, and adoption of insect-based burgers by people who initially reject them, is needed. Our study demonstrated that system dynamics models could have potential in designing new food product strategies in companies, as they facilitate decision-making and uncover knowledge gaps.

Evaluating the effect of individually-targeted food incentives on grocery purchases: The smart cart study protocol for a randomized controlled cross-over trial

BACKGROUND/AIMS

Health stakeholders are interested in the promise of healthy food incentives to improve dietary quality. The Smart Cart Study tested whether targeting healthful food incentives based on customer preferences and purchase history was effective for improving grocery purchase quality.

DESIGN

Randomized controlled crossover design of 224 adults who shopped at an independent supermarket for ≥50% of their groceries, participated in the store's loyalty program, and completed validated diet and sociodemographic/behavioral questionnaires. Participants were randomized using 1:1 blocked randomization; all participants received a 5% discount on their purchases with their loyalty card. For the first 13-weeks, the intervention group received individually-targeted weekly coupons (valued up to $10) with brief nutrition education to improve grocery purchase quality. The study team developed healthy food coupons, and the study algorithm allocated targeted coupons to participants' loyalty cards using purchase history, dietary preferences/allergies, and baseline diet quality. Control participants received weekly untargeted nutrition education and occasional generic coupons. Following a 2-4 week washout period, the two groups crossed over. The primary study outcomes were purchases of targeted products and grocery purchase quality measured using the validated Grocery Purchase Quality Index-2016; the study was powered to detect a minimum 3% difference in purchase quality.

CONCLUSIONS

The Smart Cart Study tested a novel application of automated individually-targeted marketing using customer purchase history, dietary quality, and preferences to identify and deliver targeted incentives to improve grocery purchase quality. Future research could scale this program through collaboration between multiple stakeholders, including supermarkets, workplace wellness initiatives and insurance companies.

Ethnic Food Consumption in Italy: The Role of Food Neophobia and Openness to Different Cultures

While the ethnic food market has become increasingly important in Italy, the effects of the hybridization of consumption patterns have been slowed by a consolidated culinary tradition. This study investigates the relationships among ethnic food consumption, food neophobia, and openness to different cultures with sociodemographic characteristics. A sample of 1317 Italian consumers responded to an online survey. The sociodemographic profile of the neophobic consumer appears to substantially differ from that of the consumer with an attitude of openness. Neophobic respondents are males, are older than 55 years of age, are less educated, have children, are retired, have difficulty meeting their financial responsibilities, and do not eat ethnic food. Respondents who are more open to different cultures are young adults, are highly educated, have no children, are employed, and are consumers of ethnic food. The relationship between food neophobia and openness to different cultures is confirmed to be the relationship between these variables and ethnic food consumption. The measurement of these characteristics could serve as a crucial indicator for analyzing the willingness to accept elements of novelty in an increasingly multicultural society. Additionally, consumers with the neophobic trait and who are less open to different cultures might have a less varied diet that is essential to good health.
