RESUMO
Consumers are preferring more "natural" foods, made of "healthier" and "familiar" components - the "clean-label" trend. As the population ages, understanding the older adult consumer segment becomes increasingly important. This study aims to identify the factors influencing the acceptability and liking of clean-label products in older adults living in the community. A convenience sample of 100 older adults was used for this cross-sectional study. Socio-demographic data, health status, independence level, lifestyle characteristics, nutritional status, and food and nutrient intake data were collected. The acceptability and liking for clean-label products comprised two parts: Sensory analysis with overall liking evaluation of three pairs of products, using a 9-point hedonic scale and free comments; Willingness to eat and preference assessment of nine pairs of products using the Food Action scale and a simple preference test. The participants were 80% female with a mean age of 75 years old. The overall liking for clean-label versions of cookies and mayonnaise was lower than for traditional versions. However, participants were more willing to eat the clean-label versions of products, particularly ham and yogurt. Most of the participants would prefer buying the clean-label version of all nine pairs of products, especially for ham, loaf bread, sausages, and yogurt. In sum, older adults living in the community exhibit a lower liking but, a greater willingness to eat and a higher preference for buying clean-label products. Older adults who favor clean-label products have higher levels of education and are reported to have a more adequate diet.

The knowledge of the food pattern of a population is crucial for establishing nutritional and epidemiological profiles, as well as for controlling the market of foodstuffs and to help in the management of stock of staple foods. This study aims to evaluate food consumption and its association with the underlying motives for consumers' food choices, through the application of a Food Frequency Questionnaire (FFQ) followed by a Food Choice Questionnaire (FCQ). Face to face interviews were conducted with 503 participants, recruited at their homes, workplaces, health centers and other central locations in Cape Verde, only including subjects aged ≥18 years, without a self-reported history of chronic diseases. Food frequency analysis, as well as exploratory factorial analysis (EFA) were used to determine dietary patterns and nonparametric statistical tests for comparisons and associations of variables. The EFA yielded 4 patterns termed as: "Traditional", "Western", "Balanced" and "Energetic". Using an FCQ structure of 9 factors, three different groups were obtained from hierarchical clustering. (Cabral, de Almeida, & Cunha, 2017). The results show that Cape Verdean inhabitants follow global diet trends (towards the so-called "westernization"), however, in a more moderate rate if compared to other developing country populations. Consuming "junk food" is infrequent in Cape Verde, which appears to be due to limited availability and accessibility of this type of food. The rural coastal population remains more attached to traditional foods, consuming local products and traditional dishes, whereas in the urban population, one may notice the "westernization" of consumption. The application of an FFQ in combination with the FCQ provided in-depth information on eating attitudes and behaviors.

Food fraud refers to deceptive practices conducted for economic gain, and incidents of such fraud are often reported in the media and scientific literature. However, little is known about how European consumers perceive food fraud. To address this gap, a study explored Portuguese consumers' knowledge and perceptions of food fraud using qualitative methods such as free word association and semi-structured interviews. For this research, 340 participants were recruited, providing 911 valid words, classified into categories, major categories, and dimensions. Differences between consumers' previous exposure to food fraud and sociodemographic characteristics were explored. Additionally, other thirty-six participants were selected and interviewed, following a semi-structured guide. Interviews were transcribed, coded, and analyzed using a thematic analysis procedure. The results suggest that Portuguese consumers view food fraud as a morally reprehensible deception and are aware of its causes and impacts. However, not all consumers know the different forms of food fraud or the types of products vulnerable to fraud. Among the most repeated words were "deception", "expiration date", and "falsification". Despite this food fraud awareness, most consumers believed they were not exposed to food fraud and stated that they do not conduct daily practices to reduce exposure to it. Following the chi-square and Mann-Whitney tests, significant differences (p ≤ 0.05) were identified between participants exposed and not exposed to food fraud. The study also found that consumers with higher education and self-reported exposure to food fraud had a better understanding of the issue. This study provides insights for quantitative research on consumer perceptions and beliefs about food fraud to explore further vulnerable food categories and types of food fraud in real-world scenarios.

Sensory analysis methodologies are performed in sensory booths designed to minimise external stimuli, lacking ecological validity. Immersive environments are used to introduce contextual cues, but there is a lack of studies using mixed reality systems. The main goal of this study was to evaluate an augmented virtuality (AV) system where participants are inserted into a virtual environment and evaluate a real product, being able to interact with both dimensions. A panel of 102 consumers evaluated five samples of commercial peach nectars in three sessions, each in a different environment: public food court, living room (AV environments), and laboratory (traditional sensory booth). Consumers rated overall liking, followed by open comments, and also answered an Engagement (EQ) and a Presence Questionnaire (PQ). The type of environment only affected hedonic discrimination among samples, with the laboratory setting being the only one with sample discrimination. Nonetheless, each sample was not evaluated differently across the different environments. Concerning engagement, the environment only significantly influenced the EQ's 'Affective Value' factor, being higher when using an AV system. The level of presence in the virtual environment was significantly higher in the public food court, being significantly correlated with the EQ factor scores.
RESUMO
BACKGROUND: Plant- and insect-based foods are promising alternative protein sources. Previous studies have shown that introducing plant-based foods to the diet can reduce meat intake, but no such intervention has explored the effects of insect-based foods. METHODS: This study aims to integrate alternative proteins to main meals of 80 Danish families through a 6-week two-arm randomized intervention trial to investigate acceptance, consumption, and potential for meat replacement. The primary outcome is the replacement of dietary meat protein with plant- or insect-based protein from the intervention foods assessed through change in daily meat protein intake, proportion of meat protein to total protein intake, and counts of dinner meals with meat and intervention products. CONCLUSION: The results of this study will contribute to research in alternative proteins and explore the effects of long-term exposure of meat replacement. TRIAL REGISTRATION: ClinicalTrials.gov: NCT05156853 . Registered 24 December 2021.

The Food Choice Questionnaire (FCQ) was applied to assess the motivations for daily food choices and associated factors in a Brazilian sample. Data were collected from January to July 2019 from 525 individuals over 18 years old recruited face-to-face in different places (e.g., university, public squares, health posts), using a convenient, intentional, and reasoned sampling. In addition to the FCQ, socioeconomic data were collected from printed questionnaires. Answers were given using a seven-point scale, ranging from (1) strongly disagree to (7) strongly agree. After Confirmatory factor analysis led to the rejection of the original FCQ structure, exploratory factor analysis was performed. Eight factors were extracted and named: nutritional composition, mood, health, sensory appeal, price, preparation convenience, familiarity, and purchase convenience. Other analyses were performed and led to a previously published discussion about food choice criteria hierarchy and associated factors. Researchers and practitioners can further use data from this survey in science and practice. These data can be useful for product development, nutritional counseling, and public health policies development. Furthermore, the FCQ is a widely used instrument, and comparisons between results obtained in different samples can bring meaningful contributions to the study of consumer behavior.
RESUMO
Rice and cereal consumption has become a concern for consumers due to usually high glycaemic indexes (GI), which is a critical issue for a balanced and healthy diet. Therefore, the development of new products with low GI is an important target of the industry, particularly in countries with high consumption. This study assesses consumers' perceptions about "rice" and "rice with low GI" and evaluates the effect of consumers' rice consumption profiles through the application of a free word association technique in a structured self-administered electronic questionnaire with 256 Portuguese consumers (the European market with the highest per capita consumption of rice by far). The frequency of rice consumption was evaluated, and the consumption profile was determined through a hierarchical cluster analysis, with 9% identified as daily consumers. The response words were categorized by the triangulation technique, and the association between the word categories and dimensions, sociodemographic characteristics, and consumption profile were determined. Respondents most frequently associated "rice" with rice dishes, its sensory attributes, and nutrition, highlighting the satisfaction of nutritional and hedonic needs. Consumers revealed positive expectations in relation to the functionality of "rice with low GI". The consumers' rice consumption profiles, sex, age, and educational levels influenced their perception towards "rice" and "rice with low GI". This study provides important insights for the industry to develop a consumer-oriented, low GI rice product.
RESUMO
The consumption of edible insects (EI) is traditional in many parts of the world, but not in others. In fact, despite globalization and the multiple advantages pointed out about the consumption of EI, there are still many countries where entomophagy is seen with disgust and aversion. This systematic review aimed to examine the motivations that influence the consumption of EI in diverse cultures and understand if there are differences between Western countries (WC) and insect-eating countries (IEC). It further evaluated whether the degree of acceptability was influenced by the form of consumption of the insects (eating whole insects or foods containing insects). This literature review was conducted in November 2021 within three databases, Web of Science, PubMed and Scopus, according to the Preferred Reporting of Items for Systematic Reviews and Meta-analysis and using PRISMA directives. From a total of 245 studies, 31 were selected to be included in this review, based on the inclusion criteria defined: only original research articles, from 2010 or beyond, and written in English. The results indicated that the main motivations that determine the consumption of EI are related to gender, age, sustainability, nutritional value, sensory attributes, tradition/culture, food neophobia, disgust and familiarity/past experiences. Moreover, whereas in IEC, there is a greater focus on factors related to sensory attributes, availability, affordability and preferences, in WC, there is a bigger emphasis on determinants such as nutritional value, sustainability, benefits, familiarity/past experience, tradition/culture, food neophobia and disgust. Finally, it was observed that people in WC are more willing to accept food products containing insects rather than the whole insect, which is one of the most promising points to be addressed in the future. Overall, this review highlights that there are numerous factors influencing the consumption of edible insects, and differences between WC and IEC are clear in what concerns the motivations of consumers. Hence, targeting market segments and consumers' characteristics has to be present when designing strategies to incentivize the consumption of EI in WC as a part of a global strategy for sustainability of food systems.
RESUMO
This work aimed to adapt the EsSense Profile® emotions list to the discrimination of herbal infusions, aiming to evaluate the effect of harvesting conditions on the emotional profile. A panel of 100 consumers evaluated eight organic infusions: lemon verbena, peppermint, lemon thyme, lemongrass, chamomile, lemon balm, globe amaranth and tutsan, using a check-all-that-apply (CATA) ballot with the original EsSense Profile®. A set of criteria was applied to get a discriminant list. First, the terms with low discriminant power and with a frequency mention below 35% were removed. Two focus groups were also performed to evaluate the applicability of the questionnaire. The content analysis of focus groups suggests the removal of the terms good and pleasant, recognized as sensory attributes. Six additional terms were removed, considered to be too similar to other existing emotion terms. Changes in the questionnaire, resulting in a list of 24 emotion terms for the evaluation of selected herbal infusions, were able to discriminate beyond overall liking. When comparing finer differences between plants harvested under different conditions, differences were identified for lemon verbena infusions, yielding the mechanical cut of plant tips as the one leading to a more appealing evoked emotions profile.
RESUMO
This article aims to review the current literature pertaining to the effects of eating local seasonal food on sustainable consumption. To this end, we examined definitions of seasonal and local food, the methodological approaches adopted to study the impact of seasonal consumption on sustainability, and sustainability dimensions investigated in journal articles. Highlighting what seasonal and local means, it is crucial to evaluate the effect of the consumption of these foods on sustainability. A systematic review of the literature was conducted using Scopus and Clarivate's Web of Science database in line with the recommendations from the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines. Our findings suggest that the concept of local seasonality provides relevant information to the study of sustainable consumption. However, for better use of this concept, it is crucial to define what is local. At this point, regulation of labels based on geographic proximity or political boundaries proves pertinent.
RESUMO
This study aimed to assess consumers' perceptions about the impact of consumption of different foods on health and body weight, as well as to identify risk perceptions about food-related chronic diseases. Face-to-face questionnaires were conducted with 525 Brazilians. Individuals were asked about their perception of risks associated with the consumption of 50 food items on health and bodyweight. The unrealistic optimism was measured by asking participants about their risk and the risk of another person with similar body and health conditions of developing diabetes mellitus (DM), systemic arterial hypertension (SAH), and gaining 3 to 10 kg in the next 12 months. According to the principal component analysis, biased perception of food healthiness and weight gain was observed. Some UPF were perceived as healthy (e.g., gelatin, cereal bars, cream cracker), indicating a false healthy stereotype. Regarding the bodyweight effect, some typical Brazilian staple foods, such as rice, pasta, bread, and potatoes, were considered fattening foods. Optimistic bias was found for DM, SAH, and weight gain, and perceived control over health correlated negatively to risk perception of all hazards. Some motives for food choice and perceptions about foods affected the risk perception about chronic disease. Consumers with higher income, highly educated, and without children perceive higher health benefits in food than risks. These results indicate that health campaigns must be unbiased, clarifying the level of food processing and health effects, especially for the food stereotyped as healthy and fattening.

This study aimed to evaluate the food choice motives in a sample in Brazil and to identify how socioeconomic characteristics and risk perceptions about chronic diseases and weight gain affect these motives. The Food Choice Questionnaire (FCQ) is an instrument to analyze the motivations for food choice. The FCQ was completed by 525 adult individuals in Brazil. The participants were asked about their perceived risk of gaining weight, developing diabetes, and hypertension. Confirmatory factor analysis led to the rejection of the original FCQ structure, and, after exploratory factor analysis, 30 items of the FCQ were maintained in eight factors: Nutritional Composition, Preparation Convenience, Purchase Convenience, Mood, Sensory Appeal, Health, Price, and Familiarity. Sensory Appeal and Familiarity were, respectively, the most and the least important factors involved in food choices in this sample. A high education level, high income, age, and female sex positively affected FCQ factors (except for the Price factor). On the basis of FCQ scores, we defined five clusters: Health Driven, Practicality Concerned, Shape Concerned, Food Concerned, and Cooking Enthusiasts. In general, individuals were optimistic regarding the risk of developing diabetes, hypertension, and gaining weight, especially those from the Shape Concerned cluster. The differences in food choice motives presented here reinforce the existence of different niches of food consumption. Different types of products can attract specific target groups at the time of choice.
RESUMO
Down syndrome (DS) is the most frequent chromosomal disorder. Commonly, individuals with DS have difficulties with speech and show an unusual quality in the voice. Their phenotypic characteristics include general hypotonia and maxillary hypoplasia with relative macroglossia, and these contribute to particular acoustic alterations. Subjective perceptual and acoustic assessments of the voice (Praat-4.1 software) were performed in 66 children with DS, 36 boys and 30 girls, aged 3 to 8 years. These data were compared with those of an age-matched group of children from the general population. Perceptual evaluations showed significant differences in the group of children with DS. The voice of children with DS presented a lower fundamental frequency (F(0)) with elevated dispersion. The conjunction of frequencies for formants (F(1) and F(2)) revealed a decreased distinction between the vowels, reflecting the loss of articulatory processing. The DS vocalic anatomical functional ratio represents the main distinctive parameter between the two groups studied, and it may be useful in conducting assessments.

The expected future demand for food and animal-derived protein will require environment-friendly novel food sources with high nutritional value. Insects may be one of such novel food sources. However, there needs to be an assessment of the risks associated with their consumption, including allergic risks. Therefore, we performed a systematic review aiming to analyse current data available regarding the allergic risks of consuming insects. We reviewed all reported cases of food allergy to insects, and studied the possibility of cross-reactivity and co-sensitisation between edible insects, crustaceans and house dust mites. We analysed a total of 25 articles - eight assessing the cross-reactivity/co-sensitisation between edible insects, crustaceans and house dust mites; three characterizing allergens in edible insects and 14 case reports, describing case series or prevalence studies of food allergy caused by insects. Cross-reactivity/co-sensitisation between edible insects and crustaceans seems to be clinically relevant, while it is still unknown if co-sensitisation between house dust mites and edible insects can lead to a food allergy. Additionally, more information is also needed about the molecular mechanisms underlying food allergy to insects, although current data suggest that an important role is played by arthropod pan-allergens such as tropomyosin or arginine kinase.

Down syndrome (DS) is the most common aneuploid disorder at birth. The life expectancy of persons with DS has improved over the last forty years and is now at about sixty years. Phenotypic characteristics include general hypotonia, maxillary hypoplasia with a small oral cavity and a somewhat larger appearing tongue, frequent constricted maxillary arch, nasal obstruction and others. This prospective study assesses the effects of rapid maxillary expansion (RME) on nasal patency of children with DS, using acoustic rhinometry (AR). Twenty four children with DS, aged 5 to 12 years, had been randomly allocated to the RME and control groups. AR was performed to these individuals prior to expansion, approximately one month after, post maximal expansion, and after a 5 months period of retention. The data between the two groups were compared. Rapid maxillary expansion produced a significant augmentation of nasal volume in children who had been treated (p < 0.05) compared to the control group; these results were stable through the period of retention.
