A cross-cultural perspective on feeling good in the context of foods and beverages

Emotional response to healthier foods: Influence of culture and health consciousness

Sugar, salt, and fat content in processed products are important concerns for consumers. Hence, alternative "healthy" versions of conventional foods such as chocolate, potato chips, and yogurt are offered. This work aimed to define the emotional response of consumers from different cultural backgrounds (Spain vs. Brazil) evoked by healthier versions of conventional products and the relationship between hedonic responses and health consciousness. A total of 186 Brazilian and 152 Spanish consumers participated in this online cross-cultural study. Participants answered a Health Consciousness Questionnaire and an emotional check-all-that-applies questionnaire using picture stimuli of conventional chocolate, potato chips, and yogurt and their healthier versions with less sugar, salt, and fat content, respectively. The Brazilians' emotional responses were more diverse for all stimuli compared to the Spaniards'. However, participants from both cultures rated an average of "slightly agree" on the health consciousness scale; a higher level of consumption, liking, and willingness to buy; and a higher frequency of positive emotional terms for the stimuli of conventional products compared to their healthier versions. A higher frequency of evocation of "active" is strongly associated with higher levels of health consciousness. Strategic actions by the food industry and government must consider cultural, emotional, and health-conscious factors to encourage the consumption of healthier foods. PRACTICAL APPLICATION: Food manufacturers can use the information obtained from this study to create healthier versions of their products that appeal to consumers' emotional responses and health consciousness levels. The findings can assist in designing strategic actions to promote healthier food consumption by emphasizing the benefits of healthier food choices and making them more appealing to consumers. The methodology employed in this study can also be applied to further studies aimed to assess emotional responses to food stimuli across different cultures.

Evaluating eating behavior traits of virtual targets: Attitudes and empathy

There are many common stereotypes related to food consumption and eating behaviors that are considered indicative of one's personal character. Negative evaluations of an individual based on their eating behaviors may lead to stigmatization and other harmful psychosocial outcomes. Using vignette scenarios, we examined 582 participants' attitudes towards two target characters who exhibited bitter food dislike and high reward-based eating drive respectively. In open-ended text responses, participants were more likely to respond negatively and use stigmatizing language when describing the character with high reward-based eating drive versus the character with bitter food dislike. In addition, empathic responses depended on whether participants believed they, themselves, exhibited reward-based eating drive. Participants tended to be more empathetic and more positive towards the target who shared their own reward-based eating behaviors. Interestingly, the same was not true for those who shared bitter food distaste. These results suggest that eating behaviors that are perceived as more controllable and unusual may be more negatively perceived. Targeted education or support to reduce negative attitudes about such traits may be beneficial.

Dimensions of food-related wellbeing and their relative importance among New Zealand consumers: A quasi-replication and extension approach

Research into perceived wellbeing (WB) can improve understanding of consumer food choices and support development of strategies to promote healthier and more sustainable eating habits. In this research, using online studies, food-related WB was explored among New Zealand consumers. In a "quasi-replication" of Jaeger, Prescott, and Worch (2022), Study 1 uncovered word associations to different WB-related terms ('Sense of wellbeing,' 'Lack of wellbeing,' 'Feeling good,' 'Feeling bad/unhappy,' 'Satisfied with life,' and 'Dissatisfied with life') with 912 participants in a between-subjects design. The results confirmed the multidimensional nature of WB, and the need to consider positive and negative aspects of food-related WB, as well as differences linked to physical, emotional, and spiritual WB. Drawing on Study 1, 13 characteristics of food-related WB were identified, and in Study 2 their importance for feeling a 'Sense of wellbeing' and 'Satisfied with life' was determined with 1206 participants using a between-subjects design. In a further extension, Study 2 also adopted a product-specific perspective and explored the associations of, and importance, for 16 different foods and beverages to food-related WB. Based on Best-Worst Scaling and penalty/lift analysis, the four most important characteristics overall were 'Is good quality,' 'Is healthy,' 'Is fresh,' and 'Is tasty,' with the nuance that healthiness contributed most to feeling a 'Sense of wellbeing' while good quality contributed most to feeling 'Satisfied with life.' The associations to individual foods and beverages underscored that food-related WB is a complex construct arising from an overall evaluation of the different effects of foods (including physical health, social and spiritual aspects of food consumption) and their short-term effects on food-related behaviour. Contextual and individual differences in perceptions of WB in relation to food deserve further investigation.

Development, sensitivity and reliability of a French version of the Leeds Food Preference Questionnaire (LFPQ-fr) for the evaluation of food preferences and reward

BACKGROUND

. There is a growing global interest in the evaluation of food reward, necessitating the adaptation of culturally appropriate instruments for use in empirical studies. This work presents the development and validation of a culturally adapted French version of the Leeds Food Preference Questionnaire (LFPQ-fr).

METHODS

. The LFPQ-fr was developed and validated in healthy-weight adults using the following systematic approach: i) selection and validation of appropriate food pictures; ii) linguistic translation of liking and wanting constructs in the target population (n=430; 81% female; 42.2 ± 12.7 years); iii) validation of the sensitivity and reliability of the task performed in a fasted state and in response to a standardized test meal (n=50; 50% female; 30.0 ± 8.4 years).

RESULTS

. During the first and second phases, the nutritional and perceptual validation of culturally appropriate food pictures and pertinent reward constructs, respectively, was demonstrated in a healthy-weight French sample. Findings from the third phase indicated that all food reward components were sensitive to the test meal and showed moderate to high agreement in both fasted (Lin's CCC =.72-.94) and fed (Lin's CCC = .53-.80) appetitive states between visit 1 (V1) and visit (V2). Except for explicit liking fat bias, all primary outcomes were statistically consistent in fasted and fed states between V1 and V2. Changes in fat and taste biases in response to a standardized meal for all primary outcomes were also consistent between V1 and V2 except for explicit liking fat bias (Lin's CCC = .49- .72).

CONCLUSION

. The LFPQ-fr developed and tested in this study is a reproducible and reliable method to assess food reward in both the fasted and fed states in a healthy-weight French population.

A Preliminary Study on the Validity and Stability of Projective Methods: An Application of the Structural Approach of Social Representations with Traditional Mexican Cheeses

Projective methods are qualitative tools used to study food consumer behavior. In recent years, there has been an increase in studies that use these tools to analyze consumer behavior, particularly with the word association (WA) technique. However, one of the challenges in using these methods is the stability and validity of the data. This research aimed to obtain preliminary information on the stability and validity of the associations generated by consumers with the WA technique, using the structural approach of social representations. For this, two studies were carried out; for the first study, a face-to-face survey was carried out in which 89 consumers participated, who wrote the first words that came to mind with the stimulus “Aculco” on a ballot paper. For the second study, 122 consumers completed the same task as in the first study; however, the participants were recruited from an online survey. A random sample (n = 50) of both studies was selected to explore the stability and validity of the results. In the three study samples, the words were grouped into categories and analyzed through the structural approach of social representations. The frequency of mention of the identified categories was compared with the chi-square test and the average position (AP) and the Cognitive Salience Index (CSI) were calculated. Prototype maps were built to study the structure of the categories according to the central core and peripheral areas. Cluster analysis was performed to corroborate the structure of the representations. Finally, multiple factor analysis (MFA) was performed to determine the similarity of the results obtained from the three samples using the RV coefficient. No statistical differences (p > 0.05) were identified in most of the representations (n = 11) generated from the WA task. Furthermore, the representation “Cheese and dairy products” was positioned in the central core of the three maps. The APs and the CSIs of each representation were similar in the three study samples. The RV coefficient (≥0.80) indicated similarity in the representations obtained. Results of this research can be useful for future studies that attempt to compare the stability and validity of the information based on qualitative and more flexible methodologies. Some methodological implications related to the validity and stability of projective methods are discussed.

The Shopping Behavior of International Students in Poland during COVID-19 Pandemic

The purpose of this research is to analyze the shopping behavior of international students (Asian vs. European) studying in Poland. Participants were recruited from universities located in Warsaw between June and September 2020. A total of 806 questionnaires were collected, 87 of which were eliminated due to non-response. The research sample consisted of 719 people. We conducted an exploratory factor analysis and cluster analysis for the entire study population and separately for European and Asian students. In exploratory factor analysis, two factors were extracted for the entire population, while three factors each were extracted for the European and Asian student groups. In cluster analysis, we obtained four clusters each for the entire study population and the group of European and Asian students. Our study found that among Asian students, compared to European students, there was a greater change in shopping behavior during the COVID-19 pandemic, expressed by a greater preference for online shopping, greater purchases of fruits and vegetables, purchases of local products, and shorter shopping time.

Consumer conceptualisations of food-related wellbeing: An exploration of wellbeing-related terms in four industrialised countries

Perceived (or subjective) wellbeing is regarded as key to understanding consumer food choices and the development of strategies to promote desirable eating habits. Yet, in-depth understanding of the specific factors that contribute to people's perceived wellbeing across cultures is lacking. These factors motivated the present research that used word associations to conduct an exploratory analysis of consumer conceptualisations of food-related wellbeing (WB). Adults (n = 4945) living in the United Kingdom, Australia, Singapore or Germany, speaking respectively, English or German, took part in the study. Health, pleasure, food quality, positive emotions and social aspects of food consumption were the main associations with food-related wellbeing. Absence hereof was associated with unhealthiness, disgust, negative emotions and poor mental health. The differences in these main associations emphasised the importance of exploring wellbeing, as well as lack hereof. Not doing so leads to an incomplete understanding of this multidimensional construct. The research was conducted with four terms related to wellbeing (each in their positive and negative versions): 'sense of wellbeing' and 'lack of wellbeing', 'feeling good' and 'feeling bad/unhappy', 'satisfied with life' and 'dissatisfied with life' and 'fulfilled in life' and 'unfulfilled in life'. Because these different terms gave rise to different wellbeing associations, researchers in this area must choose their empirical approach with care. The terms 'sense of wellbeing' and 'feeling good' tended to more frequently give rise to health-related associations. Conversely, 'satisfied with life' and 'fulfilled in life' tended to more frequently give rise to positive spiritual and emotional associations of food-related wellbeing. The main conceptualisations of food-related wellbeing were cross-culturally similar, but extension of the present research to other Asian countries was recommended based on several differences between Singaporean participants and those from other countries. In ethnically diverse countries like Singapore, further within-country investigations of different cultures also have merit.

Cross-Cultural Differences between Italian and UK Consumer Preferences for 'Big Top' Nectarines in Relation to Cold Storage

Nectarines are perishable fruits grown in Southern Europe, valued for their sensorial properties. Chilling is used in the supply chain for Northern European consumers, while Southern European consumers can access fresh, locally grown fruit or cold-stored supermarket fruit. Cold storage and fruit ripening affect texture and flavour. Here a consumer survey and hedonic testing compared the appreciation of nectarines (cv. Big Top) in Italy and at two UK sites (n = 359). Fruit was at the commercial harvest stage, or stored at 1 °C or 5 °C for seven days, then sampled after two days’ (Italy and one UK site) or four days’ (second UK site) ambient recovery. In the consumer survey, the most important factors involved in purchase decision were ripeness, texture, colour, taste and price. Named varieties were more important to Italian than UK respondents, whilst ripeness, price, taste, blemishes, aroma, and ‘best before date’ were more important in the UK. In sensory analyses, fruits at the commercial harvest stage were preferred to those stored at 1 °C. Preference for the 5 °C stored peaches depended on recovery time. Distinct clusters of peach sensorial attributes were positively or negatively linked to hedonic rating. Factors important in purchase decisions did not affect hedonic rating in the tasting.

How can the design thinking process improve an innovative insect-based food experience?

This work set out to show that the novel problem-solving process called design thinking (DT) can advance the acceptance and consumption of insects as food. The DT approach involving a multidisciplinary team comprised three stages: (1) an exploratory evaluation through questionnaires to raise consumer empathy, (2) an ideation stage to enable visualization and rapid prototyping, which resulted in the creation of twelve food products using mealworm larva and cricket flour and (3) an experimentation stage, where the five most promising ideas (packaging and products) were selected and tested on consumers. Four consumption trends were identified: vegetarianism (intellectual), challenge (social relationship), luxury (emotional) and sport (health). Prototypes corresponding to consumer needs were developed. After identifying the positive and negative effects elicited by the prototypes, the most promising ones were tested. Exposing consumers to small manageable steps during a food experience with insects dispelled false beliefs and overcame revulsion. The outcomes of this study are encouraging for the development of innovation in the food industry, favouring the acceptance of new foods and supporting the provision of healthier food choices for the general western population. These findings can also help companies adapt to the growing scarcity of resources and improve the value of innovations they offer the market.

What is eating well? Capability approach and empirical exploration with the population in Japan

'Eating well' or 'food-related well-being' have attracted scientific attention since the 1990s in the public health, psychology, sociology and, to a lesser degree, economics fields. A large number of empirical studies have been conducted on the content, determinants and measurements of eating well. However, what is missing is a theoretical framework that delineates the structure of well-being and highlights both the problem of one's mental 'adaptation' to straitened circumstances and the importance of one's agency and democratic practices. In this regard, Amartya Sen's capability approach shows promise. The objective of this study was to apply the capability approach to understanding what eating well means to the population in Japan and to articulate its theoretical implications. The perspective of Japanese participants was elicited by conducting a web-based questionnaire survey (n = 973). The seven categories of eating well that were identified in Japan included two objectives (health and pleasure) and five strategies (regularity, required intake, moderation, balance and quality) to achieve them. Through additional analysis of their 'actual' eating practices, it was elucidated that their satisfaction was relatively high despite their actual failure to achieve such eating well, which implies the critical importance of plural (both subjective and objective) perspectives for ethically evaluating the level of eating well.

A Conceptual Framework for Multi-Dimensional Measurements of Food Related Pleasure-The Food Pleasure Scale

In modern times, the majority of food intake is believed to be driven by hedonic processes, rather than homeostatic ones. Various factors have been found to influence the hedonic eating experience and thereby influence eating behaviour, and each factor can be regarded a piece that contributes to parts of the total picture of the hedonic response to food. As a result, the literature on the hedonic response to food-related experiences is comprehensive, but at the same time rather fragmented; and importantly, it is not clear how individuals/segments differ in key drivers of their hedonic experience and the extent to which food pleasure is perceived. In this paper, we present a conceptual framework for the development of a scale (self-report questionnaire) to measure the qualitative and quantitative aspects of food-related pleasure, the Food Pleasure Scale. We introduce the concept of (an)hedonia and scales developed in the past for its measurement, identify the spectrum of characteristics influencing food-related pleasure and explain the relevance of developing such a scale. Based on this theoretical framework, a strategy for the development of the Food Pleasure Scale is proposed.

Food-related well-being in times of crisis: Conceptual considerations and empirical findings for Syrian refugees in Germany

Migration to a new country generally entails a variety of social and economic adversities, often reflected in food practices. This paper aims to explore the hedonic dimension of well-being in a food context among a diasporic Syrian community in Stuttgart, Germany. A conceptual framework that integrates the three aspects of well-being (hedonic, psychological and social) with goals for food consumption (functional, symbolic and hedonic) was developed as a guide for the exploration. The research design used semi-structured interviews with 34 Syrian refugees and content-based analysis to obtain a detailed and profound understanding of the relational links between food and well-being. Findings reveal the affective and cognitive components of hedonic well-being and the overall perception of a good food-related life concerning food purchasing, preparation, eating and post-eating. Satisfaction in food-related life was found to be associated with food availability and accessibility, physical health and body functioning, positive emotions, sensory experience, social relationships and overall life satisfaction. The insights gained from this research help to elucidate the concept of food-related well-being in the case of conflict and displacement and to find strategies to promote the well-being of refugees.

Cross-cultural emotional response to food stimuli: Influence of consumption context

Emotional responses elicited by certain types of food can be influenced by past experiences, frequency of consumption, culture, and other personal preferences. The present research aimed i) to investigate the impact of culture (Brazilian and Spaniard) on consumers' emotional responses and acceptability of different food stimuli, and ii) to explore the influence of evoked contexts. Brazilian (n = 437) and Spanish (n = 397) participants were exposed to three visual food stimuli (image of chocolate, potato chips, and yogurt) in an online survey and reported their emotional responses. Sociodemographic data, liking, and frequency of consumption were also collected. The evoked context in our study were designed and proposed, for each product and culture, based on four dimensions (consumption time, location, social setting, and hungry state). The evoked emotional lexicon was different for each food stimulus and was clearly influenced by the cultural factor. However, there are more similarities between cultures when evaluating the same product category. The evoked contexts were appropriated and influenced the citing frequency of some emotion terms, including positive ones. The most cited emotion terms tended to positively impact product liking ratings, acting as drivers of liking. Consumption level was positively related to liking regardless of cultural interactions for both chocolate and potato chips stimuli. In conclusion, the cultural background demonstrated to be an important impact factor to be considered for understanding the effects of product, consumption occasions, and degree of liking, on emotional responses to foods. These findings offer new possibilities to be explored in marketing messages for interventions or stimuli that guide food choices.

Possibilities for Maintaining Appetite in Recovering COVID-19 Patients

COVID-19 and sequelae thereof are known to cause chemosensory dysfunction, posing a risk for intake and adequate nutrition for recovery. The overall objective of this study was to investigate the subjective strategies for maintaining appetite applied by patients recovering from COVID-19. The study included 19 in-depth interviews, focusing on patients suffering from long-term effects of COVID-19. The results were analysed using a thematic analysis for qualitative data. Results on strategies for maintaining appetite included four key themes: (1) a focus on well-functioning senses, (2) a focus on familiar foods, (3) a focus on the eating environment, and (4) a focus on post-ingestive well-being. It was found that factors prior to, during and after food intake, as well as the context, could influence desire to eat and pleasure related to food intake. As ageusia and anosmia make characterization of food difficult, being able to recognize and memorize its flavour was important to engage in consumption. Under normal circumstances, the hedonic value of food relies predominantly on the flavour of foods. When suffering from chemosensory dysfunction, shifting focus towards the texture of food, including trigeminal stimulation during consumption, were beneficial for maintaining appetite and food-related pleasure. Furthermore, a focus on the holistic satisfying feelings of choosing healthy food, as well as a focus on other people’s enjoyment during meals were reported to boost well-being around food intake. The study elaborated our understanding of the complex consequences of COVID-19, and can be applied in health promoting initiatives targeted patients recovering from COVID-19.

The association of eating behaviors with blood pressure levels in college students: a cross-sectional study

Backgrounds

The present study aimed to investigate the relationship between eating habits and blood pressure levels in college students in order to provide more insights into the prevention and control of hypertension.

Methods

A self-administered questionnaire was distributed to first-year college students. The demographic characteristics, eating behaviors, smoking and drinking status, and physical activity of 3,324 eligible respondents were analyzed. Multivariate logistics regression model was used to analyze the association of eating behaviors with blood pressure levels.

Results

The study participants had a mean (SD) age of 18.51 (1.00) years. The mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels were 114.08 and 70.92 mmHg, respectively. The overall prevalence of hypertension was 7.2%; and the prevalence among males and females was 12.9% and 3.2%, respectively. Multivariate logistic regression results confirmed that students’ taste preference, desserts, and late-night snacks were associated with hypertension. Students who ate spicy food had a lower risk of high blood pressure (OR =0.642, P=0.028); as was having dessert 3–6 times a week (OR =0.702, P=0.037), while those who ate late-night snacks on 6–7 days of the week had a higher risk for hypertension (OR =2.093, P=0.013).

Conclusions

More targeted interventions should be taken to improve students’ eating habits and control their blood pressure.

Is it possible to obtain food consumption information through children's drawings? Comparison with the Free Listing

The aims of this research were 1) to study the children's drawings to obtain scientific information about food consumption; 2) to compare this method with an existing one (Free Listing); and 3) to compare fruits- and vegetables-consumed by children of different cultural groups within a same country. Children (n = 105) from two Argentinian cities (Salta in the northwest and 9 de Julio in the Pampean region), reported the fruits and vegetables they consumed, with the Free Listing and the new Free Drawing methods. Contingency tables were built and cognitive saliency indexes (CSI) were calculated. Children evoked 57 fruits and 54 vegetables by both methods, which were then grouped into 31 fruit and 27 vegetable categories. The advantages and limitations of the methods are discussed. Throughout Free Drawing, each food was defined by its name, shape and colour, which allowed better discrimination between varieties. Children from Salta reported consuming more fruits (63.7%) and vegetables (68.6%) than those from 9 de Julio (p < 0.05). Differences between cultural groups were found in 10 fruits and 7 vegetables, mentioned more frequently in Salta, where regional crops arose principally by Free Listing. The CSI did not depend on the method used but, for vegetables, they were affected by the cultural group. The fruits with the greatest CSI were banana and apples followed by orange (CSI≥0.19). Tomatoes, carrot and pumpkins showed the highest CSI in 9 de Julio; while carrot, tomatoes, varieties of lettuce and potatoes had the highest CSI in Salta (0.17 ≤ CSI≤0.33). Free Drawing is a qualitative alternative to study food consumption in children populations through a fun activity without the need for assistants.

Effect of Experiential Vegetable Education Program on Mediating Factors of Vegetable Consumption in Australian Primary School Students: A Cluster-Randomized Controlled Trial

Schools provide a relevant and equitable environment to influence students towards increased vegetable consumption. This study aimed to evaluate the effectiveness of a Vegetable Education Resource To Increase Children’s Acceptance and Liking (VERTICAL) for Australian primary schools (curriculum aligned and based on a framework of food preference development and sensory experiential learning) on positively influencing factors predisposing children towards increased vegetable consumption. The secondary aim was to evaluate two levels of teacher training intensity on intervention effectiveness. A cluster-RCT amongst schools with three conditions was conducted: 1 = teaching VERTICAL preceded by online teacher training; 2 = as per 1 with additional face-to-face teacher training; 3 = Control. Pre-test, post-test and 3-month follow-up measures (knowledge, verbalization ability, vegetable acceptance, behavioural intentions, willing to taste, new vegetables consumed) were collected from students (n = 1639 from 25 schools in Sydney/Adelaide, Australia). Data were analyzed using mixed model analysis. No difference in intervention effectiveness was found between the two training methods. Compared to the Control, VERTICAL positively affected all outcome measures after intervention (p < 0.01) with knowledge sustained at 3-month follow-up (p < 0.001). In conclusion, VERTICAL was effective in achieving change amongst students in mediating factors known to be positively associated with vegetable consumption.

Physicochemical Properties and Consumer Acceptance of Bread Enriched with Alternative Proteins

A projected global population growth by 2050 and climate change crises have led to increasing demand in edible protein sources; thus, scientific research and food industries are searching for alternatives. In this study, we investigated the incorporation of plant- and insect-based protein sources in wheat-based formulations. The Alveographic properties of dough and the effects on bread physicochemical and sensory characteristics were analysed. Including pea protein or insect powder improved the nutritional value, increasing protein content, but influenced the dough and bread properties. Pea protein significantly increased the dough extensibility (L), tenacity (P), and their ratio (P/L) in dough with insect blends and the control. Bread texture properties were significantly affected by the addition of pea and insect flour. Higher amounts of pea protein incorporation increased hardness values and showed a mean cell area lower than the control bread. Crust colour analysis showed significant differences concerning the control bread, while crumb colour was affected by the flour colour. Word association analysis showed insect bread was associated with an emotional dimension, wheat bread was linked with “tradition”, and pea bread was associated with “fruit and vegetable”.

Post-Ingestive Sensations Driving Post-Ingestive Food Pleasure: A Cross-Cultural Consumer Study Comparing Denmark and China

Culture is one of the main factors that influence food assessment. This cross-cultural research aimed to compare Chinese and Danish consumers in their post-ingestive drivers of Post-Ingestive Food Pleasure (PIFP). We define PIFP as a “subjective conscious sensation of pleasure and joy experienced after eating”. We conducted two in-country consumer studies in Denmark (n = 48) and in China (n = 53), measuring post-ingestive sensations and PIFP using visual analogue scale, for three hours following consumption of a breakfast meal. Key results revealed perceived Satisfaction, Mental, Overall and Physical wellbeing to be highly influential on PIFP in both countries. Moreover, Danish consumers perceived appetite-related sensations such as Satiety, Hunger, Desire-to-eat and In-need-of-food to be influential on PIFP, which was not the case in China. In China, more vitality-related sensations such as Energized, Relaxation and Concentration were found to be drivers of PIFP. These results suggest similarities but also distinct subtleties in the cultural constructs of PIFP in Denmark and in China. Focusing on Food Pleasure as a post-ingestive measure provides valuable output, deeper insights into what drives Food Pleasure, and, importantly, takes us beyond the processes only active during the actual eating event.

Challenges in the interpretation and therapeutic manipulation of human ingestive microstructure

This minireview focuses on the interpretative value of ingestive microstructure by summarizing observations from both rodent and human studies. Preliminary data on the therapeutic manipulation of distinct microstructural components of eating are also outlined. In rodents, the interpretative framework of ingestive microstructure mainly concentrates on deprivation state, palatability, satiation, and the role of learning from previous experiences. In humans, however, the control of eating is further influenced by genetic, psychosocial, cultural, and environmental factors, which add complexity and challenges to the interpretation of the microstructure of meal intake. Nevertheless, the presented findings stress the importance of microstructural analyses of ingestion, as a method to investigate specific behavioral variables that underlie the regulation of appetite control.
