Instruments to Evaluate Food Neophobia in Children: An Integrative Review with a Systematic Approach.

Food neophobia (FN), a frequent disorder in childhood, profoundly impacts the quality of a diet, restricting the intake of nutrients to maintain proper nutrition. Therefore, using the appropriate tools to assess FN in children to promote healthy eating habits is essential. The study aimed to develop an integrative review with a systematic approach to identify the instruments to measure FN in children and analyze their differences. The included studies (n = 17) were more concentrated in Europe, demonstrating the possible lack of dissemination of the topic at a global level. Among the 18 tools, 6 were represented by adaptations of the Food Neophobia Scale (FNS) and the Children's Food Neophobia Scale (CFNS), and one was the CFNS itself, demonstrating the relevance of these pioneering tools. The need to meet mainly cultural and cognitive criteria led to the creation of other instruments (n = 11). A diversity of approaches concerning the respondents, age range, items, scales, and validation methods was revealed. Modifications to the tools in some nations highlighted their adaptability and effectiveness in addressing regional variations. The instruments can contribute to additional research to help us better understand the prevalence of FN in children, resulting in their health and well-being.

Food neophobia, risk perception and attitudes associations of Brazilian consumers towards non-conventional edible plants and research on sale promotional strategies.

Non-conventional edible plants (NCEP) are plants or parts of plants that are not usually consumed by the population and have limited geographic distribution. This study investigated the consumption of NCEP, the influence of Food Neophobia and risk perception on Brazilian consumers attitudes as well as purchase preferences to determinate the best sale promotional strategy. Participants (n = 271) answered the online questionnaire that consisted of socio-demographic questions, items about consumption (open questions), Food Neophobia Scale, risk perception (to assign the level risk) and attitudes towards NCEP (using 5-point Likert scale). Fisher's exact test was used to investigate possible associations. Task purchase choice was evaluated using the Best-Worst Scale. The most consumed conventional leafy vegetables were collard greens (Brassica oleracea L. var. acephala D.C) (95.6%) and lettuce (Lactuca sativa) (88.5%). As for NCEP, taioba (Xanthosoma taioba E.G) (26.7%), bertalha (Basela alba L.) (23.3%) and beldroega (Portulaca oleracea L.) (14.1%) were the most cited leafy vegetables. High food neophobia individuals demonstrated to try NCEP if its nutritional value and safety are proven, showing a demand for such strategy, this would increase the consumption of these vegetables. The perception of a high risk was also associated with the inclusion of NCEP in the diet. The inclusion of NCEP at the moment of purchase, even at a higher price, presented higher scores when compared to the purchase of only conventional vegetables, at lower prices. Despite this, the price can still be a limiting factor and the search for promotional strategies should be reinforced to increase the commercialization of NCEP at street markets.

Food selectivity and neophobia in children with autism spectrum disorder and neurotypical development: a systematic review.

CONTEXT: Individuals with autism spectrum disorder (ASD) have common eating problems, including food refusal, dietary restrictions, and behavioral problems during eating. OBJECTIVE: The aim of this systematic review was to find more clear evidence on the relationship between food selectivity or food neophobia (FN) and ASD in children up to age 14 years. The PECO-based question was: Are food selectivity and FN behaviors more prevalent in children with ASD than in children with neurotypical development (NTD)?, in which the P is children, E is ASD, C is children with NTD, and O is food selectivity and FN. DATA SOURCES: Clinical studies in the databases PubMed, Embase and Web of Science, comparing children with ASD and those with NTD, were reviewed from October 1966 to October 2021. STUDY SELECTION AND DATA EXTRACTION: A total of 122 studies were analyzed for summary reading, and only 17 of these were included in the descriptive qualitative analysis. In 9 studies, the analysis of food selectivity was performed via a questionnaire. RESULTS: The results showed that children with ASD are more selective than those with NTD. Four studies evaluated FN through scales; however, only 2 found higher levels of FN in the ASD group than in children with NTD. The sensory profile was measured using questionnaires in 9 studies, and we found that altered sensory processing is more common in children with ASD. CONCLUSION: Children with ASD present greater food selectivity than children with NTD. However, the occurrence of FN was higher in only 50% in which FN was investigated, which points to a need for studies that compare FN between siblings with ASD and those with NTD in the same family nucleus. In addition, atypical oral sensitivity seems to be a sensory characteristic most related to eating disorders. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42021247880.

Environmental enrichment strategies for weaned pigs: Welfare and behavior.

This research aims to evaluate the effects of different types and strategies of environmental enrichment for weaned pigs on behavior. Forty weaned piglets aged 21 to 28 days were distributed in a completely randomized design in five treatments: without enrichment object, full-time cognitive enrichment, intermittent cognitive enrichment, alternate cognitive and sensory enrichment every 24 hours, and alternate cognitive and sensory enrichment every 48 hours. Behavioral observations were made for 15 days considering pig as experimental unit. Pigs of control and continuous cognitive enrichment treatments were submitted to human approach test, novel arena test, and novel object test. Pigs kept in an unstimulated environment show a higher frequency of unwanted behaviors compared to pigs in other treatments regardless of enrichment type. Pigs with alternation of enrichment type every 24 hours showed a longer interaction time with enrichment objects. Enrichment objects in rearing environment during nursery phase reduced undesirable behaviors and reactivity to unknown situations. Strategies such as alternating the type of enrichment every 24 or 48 hours are effective in maintaining the novelty and the animals' interest.

Food Neophobia in Children with Autistic Spectrum Disorder (ASD): A Nationwide Study in Brazil.

Food neophobia (FN) is common among children with autistic spectrum disorder (ASD), potentially impairing their health and diet quality. This study aimed to investigate and classify the prevalence of FN among 4-to-11-year-old Brazilian children with ASD. This descriptive cross-sectional study was performed by applying online a validated instrument to identify FN in Brazilian children with ASD through their caregivers' responses for a national prevalence of FN in this group. The final sample included 593 children with ASD, 80.1% of boys, with a mean age of 6.72 ± 2.31 years, and 83% having only ASD. Almost 75% (n = 436) of the children with ASD had high food neophobia scores. The fruit neophobia domain had the lowest prevalence of high neophobia (63.7%). No significant difference in FN (total, fruit, and vegetable domains) was found, considering gender and age. There was no statistical difference in FN (all domains) by the number of residents in the same household, income, or the caregivers' educational level. FN did not decrease in older children with ASD. FN is a more complex problem, requiring a multidisciplinary trained team to face the problem.

On how people deal with industrialized and non-industrialized food: A theoretical analysis.

"Canned, frozen, processed, ultra-processed, functional" etc. Two hundred years after the beginning of the food industry, industrialized food has evolved with many labels. Every person in the world eats and has different experiences with food that are connected to culture and social relationships which permeate our daily lives in many kinds of situations. Food evokes feelings, beliefs, desires, and moral values. For many people, food not only satisfies hunger and sustains life, but it also brings a delicious pleasure that is with their history, culture, and ancestry. Today's food industry pushes products through its marketing, which promotes a plethora of claims that have now trended proportionally with neophobic dimensions. In reality, the general public lacks objective knowledge about the complex science of modern food technology because of its low transparency, and this has resulted in the appearance of misleading ideas that can prejudice the correct analysis of food values. Given this, education about food is an urgent need. Notably, food scientists, technologists, and engineers must look at eaters through the prism of consumers who are human beings in all their rich social/anthropological diversity. The objective of this article is to explore the elemental anthropologic aspects of foods and how they can affect consumer's trust in the food industry's role.

Food Selectivity and Its Implications Associated with Gastrointestinal Disorders in Children with Autism Spectrum Disorders.

Food selectivity (FS) in children with autism spectrum disorders (ASD) is common, and its impact on a nutritional level is known. However, the etiology of gastrointestinal disorders (GID) related to alterations in the intestinal microbiota in children with ASD remains unclear. This article provides a narrative review of the literature on FS from the last 15 years, and its relationship with GID in children with ASD. Sensory aversion in ASD leads to food elimination, based on consistencies, preferences, and other sensory issues. The restriction of food groups that modulate the gut microbiota, such as fruits and vegetables, as well as the fibers of some cereals, triggers an intestinal dysbiosis with increased abundance in Enterobacteriaceae, Salmonella Escherichia/Shigella, and Clostridium XIVa, which, together with an aberrant immune response and a leaky gut, may trigger GID. It is observed that FS can be the product of previous GID. GID could provide information to generate a hypothesis of the bidirectional relationship between FS and GID. Emphasis is placed on the need for more studies with methodological rigor in selecting children with ASD, the need for homogeneous criteria in the evaluation of GID, and the adequate classification of FS in children with ASD.

A WhatsApp-Based Intervention to Improve Maternal Social Support and Maternal-Child Health in Southern Brazil: The Text-Message Intervention to Enhance Social Support (TIES) Feasibility Study.

Participatory learning and action cycles with women's groups have been recommended by the WHO to promote maternal and newborn health, but few studies have tested its feasibility and acceptability in mobile health (mHealth) interventions among mothers of toddlers. This was a mixed-method feasibility assessment of an 8-week WhatsApp-based maternal support group for mothers of toddlers (12-18 months of age) enrolled in a birth cohort study in Southern Brazil. Daily messages and weekly activities were sent by moderators to promote maternal-child outcomes: child nutrition, child sleep, nurturing care, and maternal psychosocial well-being (assessed pre- and post-intervention via self-reported questionnaire). The implementation and engagement of the mothers in the program were assessed by message extraction. Acceptability was evaluated through in-depth interviews (n = 5) and open-ended surveys (n = 10). 1481 messages were exchanged in 3 WhatsApp groups (n = 30 mothers). Mothers were most active on weekdays (68.6% of messages sent on Tuesdays and 72.6% on Thursdays), afternoons (2:00-4:00pm), and evenings (9:00-11:00 pm). Engagement was higher at weeks 1-4. Mothers enjoyed and considered topics relevant. Group interaction was perceived as low, which influenced their participation. The prevalence of depression symptoms decreased from pre- to post-intervention (9% to 5%; P = .04). A moderated mobile-based support group for mothers of toddlers was feasible. mHealth services to promote maternal support are a promising strategy to improve maternal-child outcomes, but engagement and use of the service remains a challenge. Program managers should work with community members to identify ways to support engagement and participation throughout the intervention.

Market Expansion of Caffeine-Containing Products: Italian and Argentinian Yerba Mate Consumer Behavior and Health Perception.

Mate is the most consumed beverage in South America. There is interest in expanding yerba mate sales into the old and new markets by promoting its health properties and energizing effects. The research study aims to explore Argentinian and Italian purchasing and consumption behavior and perception of yerba mate. The exploration includes agro-food chain stakeholders' views, and consumers' habits, perception, knowledge of yerba mate in relation to other market positioning caffeine-containing products. Data collection includes qualitative method, such as interviews with agro-food chain stakeholders, that is producers, processors, consumers, and quantitative consumer survey. Data collection was carried out in Argentina and in Italy. Results show that in Argentina yerba mate consumption is driven by habit and tradition, and in Italy yerba mate is mostly unknown. Consumers tend to drink yerba mate in Argentina and other caffeine-containing beverages in Italy to socialize, and as source of energy. Consumers have little awareness of yerba mate antioxidant properties. Yerba mate provides the energy of coffee drinking, and the taste and pleasure of tea drinking. Italian consumers' key challenge to yerba mate drinking is the longer time it takes, compared to the usual espresso. Italians perceive it as an energetic or relaxing beverage, with a consumption experience similar to tea and infusions. There is need to update commercialization strategy of yerba mate in Italy.

Not as Bad as I Thought: Consumers' Positive Attitudes Toward Innovative Insect-Based Foods.

Considering that the demand for food will increase by 70% by 2050, consuming insect-based foods appears as a protein alternative due to their nutritional quality and low environmental impact. However, there is a need to investigate the acceptance of these innovative foods, especially in traditional meat-eating markets, such as in Southern Brazil (land of the Gauchos). The purpose of this manuscript is to analyze consumers' attitudes toward innovative insect-based foods. The methodological procedures were divided into two stages. In the qualitative stage, 14 interviews were conducted regarding meat consumption habits. In the quantitative stage, a survey was carried out with 433 consumers. A factor and cluster analysis were performed, and two different groups of consumers were found. The results clearly show a segment with positive attitudes toward insect-based foods. This group had a low degree of neophobia. The products were perceived as not tasty and disgusting, but they were considered modern, with high nutritional value, positive, safe, and beneficial to the environment. Appearance, price, and packaging, combined with flavor, proved to be the attributes considered by consumers as the most important for their acceptance.

Low adherence to traditional dietary pattern and food preferences of low-income preschool children with food neophobia.

OBJECTIVE: To associate dietary patterns and food neophobia in low-income preschoolers. DESIGN: This was a cross-sectional study using a semi-structured questionnaire for socio-demographic data, birth conditions and breast-feeding history. Food neophobia was assessed using an adapted version of the Child Food Neophobia Scale. Children's nutritional status was assessed using BMI-for-age and height-for-age Z-scores. Dietary patterns were estimated using a semi-quantitative FFQ through exploratory factor analysis. Multiple linear regression was used to test for an association between food neophobia and dietary pattern adherence. SETTING: Philanthropic childhood education schools in Aracaju, an urban community in northeastern Brazil, between July and December 2017. PARTICIPANTS: Two hundred fourteen children aged 3-6 years and their parents. RESULTS: The percentages of low/medium and high food neophobia among preschoolers were 85·9 % and 11·2 %, respectively. Children with high food neophobia more frequently consumed ultra-processed foods rich in sugars (snacks, filled and unfilled cookies and sweets), as well as protein-rich foods (white meat, cheese and yogurt). Three dietary patterns were identified (traditional, snacks and school snacks). Children with a high level of neophobia had lower adherence to traditional dietary patterns. CONCLUSIONS: A high level of food neophobia among socially vulnerable preschoolers is an eating behaviour related to unhealthy eating and is associated with the poorest diet in typical foods.

Factors associated with food neophobia in children: systematic review / Fatores associados à neofobia alimentar em crianças: revisão sistemática

ABSTRACT 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.

RESUMO Objetivo: Identificar os fatores associados à neofobia alimentar em crianças por meio de uma revisão sistemática. Fontes de dados: Esta pesquisa foi baseada nas recomendações do Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A busca foi realizada nas bases de dados PubMed, ScienceDirect e Scientific Electronic Library Online (SciELO), com a conjugação dos descritores em saúde em português e inglês: ("Food Neophobia" OR "Feeding Behavior" OR "Food Preferences" OR "Food Selectivity") AND Child, no período de 2000 a 2019. Foram incluídos os estudos que avaliaram os fatores associados à neofobia alimentar em crianças. A qualidade dos estudos foi mensurada por meio da ferramenta Effective Public Health Practice Project: Quality Assessment Tool for Quantitative Studies (QATQS). Síntese dos dados: Dezenove trabalhos foram incluídos na revisão sistemática. A prevalência da neofobia alimentar variou de 12,8 a 100%. Os estudos utilizaram três diferentes escalas a fim de medir o nível de neofobia alimentar. Os principais fatores associados a esse quadro foram: influência parental nos hábitos alimentares da criança, preferência inata das crianças por sabores doces e salgados, influência do aspecto sensorial do alimento, pressão dos pais para a criança comer, falta de encorajamento e/ou afetividade dos pais no momento das refeições, ansiedade na infância, dietas pouco variadas e com baixa qualidade nutricional. Conclusões: Os fatores associados à neofobia alimentar permeiam diversos âmbitos da vida da criança, assim, o acompanhamento interprofissional torna-se essencial no processo de intervenção.

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.

Cross-cultural validation of the short version of the Food Disgust Scale in ten countries.

The cross-cultural testing of scales represents an important step in the scale validation process. The present study evaluated whether the eight-item short version of the recently developed Food Disgust Scale (FDS-short) is a reliable and valid tool for measuring food disgust sensitivity in ten countries: Australia, China, England, France, Germany, Mexico, South Africa, Spain, Sweden, and the USA. In an online survey, the participants (N = 6128) answered items from the FDS-short and other scales related to (food) disgust sensitivity so as to test the construct and criterion validity of the FDS-short. Confirmatory factor analysis of the one-factor structure of the FDS-short revealed an adequate to good model fit in all the countries except for China. Multiple group analysis to test measurement invariance showed the FDS-short to be metrically invariant in all the tested countries (except for China) relative to Australia. With regard to the construct validity, significant positive correlations were observed in all the countries between the FDS-short and pathogen disgust sensitivity, sexual disgust sensitivity, moral disgust sensitivity, germ aversion, and food neophobia. Criterion validity of the FDS-short in all the tested countries was confirmed by the positive correlations between it and having a sensitive stomach, experiencing gastrointestinal complaints after eating animal-based foods (except for France and Germany), and the perceived infection risk of food-borne diseases in one's country. The direction of the correlations indicated that for each country, those with higher FDS-short scores also scored higher on all the tested constructs than those with lower FDS-short scores. Taken together, the present results indicate that the FDS-short is a reliable and valid tool for assessing food disgust sensitivity across countries.

Neofobia alimentaria y trastornos de conducta alimentaria: Impacto en la adherencia a la dieta mediterránea de universitarios españoles / Food neophobia and eating disorders: Impact on adherence to the Mediterranean diet of Spanish university students

RESUMEN Este estudio evaluó la actitud de los universitarios murcianos hacia los nuevos alimentos y su relación con la adherencia a la dieta mediterránea, el riesgo de alteraciones de la conducta alimentaria y su asociación con la masa corporal. Participaron estudiantes de la Universidad de Murcia a los cuales se realizaron mediciones antropométricas, peso y talla, para estimar el índice de masa corporal y se estableció su condición nutricional, y se aplicaron las encuestas para identificación de trastornos de conducta alimentaria y neofobia alimentaria. Participaron un total de 300 universitarios con un promedio de edad de 21.3 años. Sólo el 14% de las mujeres y 35% de los hombres presentaron exceso de peso. Un 44% presentan buena adherencia a la dieta mediterránea. La Neofobia fue ligeramente mayor en mujeres que en hombres. Entre los resultados se identificó que existen más conductas de trastornos de conducta alimentaria (15.5%) que neofobia (11.5%), impactando negativamente a la adherencia a la dieta mediterránea. Los universitarios de la Región de Murcia, presentan una puntuación en trastorno de la conducta alimentaria inferior a la reportada por otros autores, no existiendo diferencias significativas entre esta y el sexo, la adherencia a la dieta mediterránea o el IMC.

ABSTRACT The study was designed to evaluate the attitude of Spanish undergraduates towards new foods and its impact on adherence to the Mediterranean diet, risk of altered eating behavior and its association with body mass. Undergraduates of the University of Murcia were invited to participate. Anthropometry (weight and height) was measured to estimate body mass and nutritional status and surveys were administered to identify eating disorders and food neophobia. A total of 300 undergraduates participated, with a mean age of 21.3 years. Only 14% of the women and 35% of the men were overweight; 44% had good adherence to the Mediterranean diet. Neophobia is slightly higher in females than males. We observed more eating disorder behaviors (15.5%) compared to food neophobia (11.5%) and that both negatively impacted the adherence to the Mediterranean diet. Undergraduates from the Murcia Region, reported an eating disorder values lower than that reported by other authors. No significant differences were found between this and sex, adherence to the Mediterranean diet or BMI.

Edible Insects Processing: Traditional and Innovative Technologies.

Insects are part of the human diet in many parts of the world. Their nutritional value is widely recognized. Currently, most edible insects are harvested from the wild, although semi-domestication and indoor farming have increased insect availability and the sustainability of production. In traditional cultures, insects are processed in a number of ways (steaming, roasting, smoking, frying, stewing, and curing, among others) to improve their sensory and nutritional qualities as well as their shelf-life. In order to increase consumer interest in the West, various technologies have been developed that are aimed primarily at using insects as ingredients in a non-recognizable form, such as powders or flour. These technologies include drying (sun-drying, freeze-drying, oven-drying, fluidized bed drying, and microwave-drying) and new processing methods (ultrasound-assisted extraction, cold atmospheric pressure plasma, and dry fractionation) designed mainly for protein, fat, and/or chitin extraction. Insect-based ingredients are sold for the production of cookies, chocolates, tortilla-style chips, and other snacks. This review focuses on edible insect production, processing technologies, and commercialization using strategies ranging from traditional to novel as a sustainable approach for improving food security worldwide.

Brazilian consumers' perception of edible insects / Percepção de consumidores brasileiros aos insetos comestíveis

ABSTRACT: It is estimated that by 2050 the world population will be 9 billion people; and therefore, the need for alternative sources of protein is inevitable, since conventional sources, such as beef, pork and poultry, will not be sufficient to meet the demand of population growth. Food that includes alternative sources of protein, such as insects, is a reality in countries of Latin America, Asia, Australia, Europe and Africa. This research presents the results of an exploratory study that analysed the food profile of 1,619 consumers in the five Brazilian regions (North, Northeast, Midwest, Southeast and South) as well as their perception, motivation and preferred form of edible insects. The data were analysed by cross-tabulation and expressed as frequencies. Our results show that women are more reluctant than men to consume insects. In general, there is a preference for consumption of insects in the form of flour. However, those with more familiarity with this type of consumption prefer the whole insect. Most Brazilian consumers have no opinion about the safety of consuming insects; however, consumers with higher levels of education and familiarity consider it safe.

RESUMO: Estima-se que em 2050 a população mundial contará com cerca de 9 bilhões de pessoas, e, portanto, a necessidade de fontes alternativas de proteína é inevitável, uma vez que as fontes convencionais, como carne de gado, suínos e aves, não serão suficientes para suprir a demanda do crescimento populacional. A alimentação que inclui fontes alternativas de proteína, como os insetos, é uma realidade em países da América Latina, Ásia, Austrália, Europa e África. Esta pesquisa apresenta os resultados de um estudo exploratório que analisou o perfil alimentar de 1.619 consumidores das cinco regiões brasileiras (Norte, Nordeste, Centro-Oeste, Sudeste e Sul) quanto sua percepção, motivação e forma preferencial aos insetos comestíveis. Os dados foram analisados através de frequências cruzadas e expressos em porcentagem. Nossos resultados mostram que mulheres apresentam maior aversão ao consumo de insetos do que homens. Em geral, há preferência em consumir os insetos na forma de farinha, e inteiro para aqueles com mais familiaridade ao consumo de insetos. Majoritariamente, os consumidores brasileiros não tem opinião sobre a segurança em consumir insetos, contudo, em maiores níveis de escolaridade e a familiaridade os consumidores posicionam-se quanto à sua segurança.

Plasticity in the Interoceptive System.

The most outstanding manifestations of the plastic capacities of brain circuits and their neuronal and synaptic components in the adult CNS are learning and memory. A reduced number of basic plastic mechanisms underlie learning capacities at many levels and regions of the brain. The interoceptive system is no exception, and some of the most studied behavioral changes that involve learning and memory engage the interoceptive pathways at many levels of their anatomical and functional organization.In this chapter, we will review four examples of learning, mostly in rats, where the interoceptive system has a role. In the case of conditioned taste aversion, the interoceptive system is of outstanding importance. In drug addiction, the role of the insular cortex - the highest level of the interoceptive system- is unusual and complex, as many forebrain regions are engaged by the process of addiction. In the third example, neophobia, the gustatory region of the insular cortex plays a major role. Finally, the role of different areas of the insular cortex in different processes of aversive memory, particularly fear conditioning, will be reviewed.

Neophobia is negatively related to reversal learning ability in females of a generalist bird of prey, the Chimango Caracara, Milvago chimango.

In an ever-changing environment, the ability to adapt choices to new conditions is essential for daily living and ultimately, for survival. Behavioural flexibility allows animals to maximise survival and reproduction in novel settings by adjusting their behaviour based on specific information and feedback acquired in their current environments. However, a growing body of evidence indicates that an individual's personality type can limit the extent to which the individual might behave flexibly, by influencing the way an individual pays attention to novelty and how much information it collects and stores, which in turn affects the individual's decision-making and learning process. In this study, the behavioural flexibility of a generalist predator, the Chimango Caracara, Milvago chimango, was analysed using the reversal learning paradigm, focusing on the comparison between age classes, and the relation of learning flexibility with a personality trait, the level of neophobia. Due to the low number of male individuals captured, this study was carried out only with female birds. The results showed that age had no significant effect either on the acquisition of a stimulus-reward association, or on the capacity of reversing this previously learned association. Reversal of the response was a harder task for these birds in comparison with the initial acquisition process. The individual's performances in the learning tasks seemed to be uncorrelated with each other, suggesting that they involve different neural mechanisms. Contrary to the general pattern observed in the majority of previous work on personality and cognition in non-human animals, the level of neophobia did not correlate with the initial associative learning performance in both adults and juveniles, yet it showed a significant negative relationship with reversal learning ability, mainly in the regressive phase of this task, for the two age classes. Our results suggest that the predatory and generalist lifestyle of female individuals of M. chimango along with the selective pressures of the environment of the individuals studied might play a critical role in the degree and direction of the linkage between novelty response and learning flexibility observed in this study.
