RESUMO

BACKGROUND: The food choices of migrants are frequently limited by lack of access to sufficient and adequate food. Food insecurity (FI) during adolescence has potential negative health consequences, however the experiences of FI of adolescent in-transit migrants have seldom been reported. OBJECTIVE: To explore the experiences of FI of adolescent in-transit migrants and their ways of coping with it. METHODS: Qualitative study, with 19 semi-structured interviews with adolescents (ages 13-19 years), in shelters for migrants in Mexico in 2022-2023. We followed a reflexive thematic analysis strategy. RESULTS: Most participants had experienced FI during the journey, and responded by limiting intake, choosing food according to price, seeking temporary work or asking for food or money in the streets. We defined "solidarity through food" as a central theme that summarized participants' experiences of sharing food with other migrants, as givers or recipients. Solidarity through food was a response to FI, benefitting the more disadvantaged (e.g. young children, those who had been robbed). Despite their young age, interviewees took part in this, giving their food to others and restricting their intake to prioritize younger siblings. DISCUSSION/CONCLUSIONS: Solidarity through food was a form of generalized reciprocity, enacted not only among family members or friends, but extended to other migrants sharing the route. In further studies, it will be important to explore the role and nuances of food sharing as a practice of social exchange of responsibility and care, on adolescent migrants' health, and in their psychological and relational development into adulthood.

RESUMO

The failure rate of restaurants is high in many countries, primarily because of the complex relationships between services and customers. Therefore, improving restaurant customer experience is a significant challenge for entrepreneurs. This multi-dimensional experience encompasses several aspects that may or may not be related to food consumption. Many restaurant owners can avoid bankruptcy if they understand theories of service quality and the factors involved. The objective of this research is to identify and summarize known important factors that lead consumers to choose, patronize or be satisfied with a restaurant. The research question for this review is: What are the important factors that influence consumers (population) to choose, patronize, or be satisfied with a restaurant  (outcome)? Therefore, we conducted an integrative review to address this question. We included 111 studies and identified 117 factors/indicators related to consumer satisfaction and restaurant choices. First, we grouped these factors into four categories based on the Big Four restaurant attributes: atmosphere, food, service, and price & value. Four categories emerged based on consumer- and business-related aspects: behavioral intentions, values and beliefs, experiences, and companies. The "food" category is the most important factor in consumer choice and experience. However, the importance of this category may vary depending on the situation (e.g., lunch, dinner, weekends, weekdays) and should be carefully considered, as all categories were relevant but intricate. Such factors are associated with many positive outcomes, such as satisfaction, loyalty, brand love, patronization, and intent to visit and revisit.

RESUMO

We examined the relationships between three eating behaviors and nine motives underlying food choices made by Brazilian adults. Using participant responses to the short version of the Three-Factor Eating Questionnaire and the Food Choice Questionnaire, we investigated eating behaviors (cognitive restriction, uncontrolled eating, and emotional eating) and motives for food choices (health, mood, convenience, sensory appeal, natural content, price, weight control, familiarity, and ethical concern). We used a structural equation model to test relationship pathways (ß), with eating behaviors as independent variables and motives for food choices as dependent variables. Participants were 1297 individuals (69.5% female) with a mean age of 25.0 years (SD = 5.8). We confirmed the validity and reliability of the questionnaires in this sample. Restrictive eating behavior was significantly related to motives of health (ß = .415), mood (ß = .127), natural content (ß = .364), weight control (ß = .681), and ethical concern (ß = .161). Emotional eating behavior was related to motives of mood (ß = .277), health (ß = -.137), and natural content (ß = -.136). Uncontrolled eating behavior was related to motives of convenience (ß = .226), sensory appeal (ß = .121), price (ß = .153), and familiarity (ß = .090). We believe these findings can now help design future research and clinical interventions for managing people's risky eating behaviors and promoting beneficial food choices.

RESUMO

The association between socioeconomic status (SES) and chronic disease has recently become more evident in middle- and low-income countries. We hypothesized that poor socioeconomic conditions, such as food insecurity, low educational level, or low SES, may restrict access to a healthy diet and may be associated with cardiometabolic risk independently of body fat. This study examined the relation between socioeconomic indicators, body fat, and cardiometabolic disease risk markers in a random sample of mothers living in Queretaro, Mexico. Young and middle-aged mothers (n = 321) answered validated questionnaires to determine SES, food insecurity, and educational level and a semiquantitative food frequency questionnaire to determine dietary patterns and the cost of individual diet. Clinical measurements included anthropometry, blood pressure, lipids profile, glucose, and insulin. Obesity was present in 29% of the participants. Women with moderate food insecurity had higher waist circumference, glucose, insulin, and homeostasis model assessment of insulin resistance than women with food security. High triglyceride concentration and lower levels of high-density lipoprotein and low-density lipoprotein cholesterol were associated with lower SES and lower educational level. Women who consumed a lower carbohydrate diet had higher SES, higher education, and better cardiovascular risk markers. The higher carbohydrate diet profile was the least expensive diet. There was an inverse association between the cost and energy-density of foods. In conclusion, food insecurity was associated with glycemic control markers, and lower SES and education were related to a low-cost, higher carbohydrate diet and to a greater cardiovascular risk. The influence of the social environment on obesity and cardiovascular diseases needs to be further explored.

RESUMO

Quantitative abilities are well described in many species and in diverse life situations, including in the adult domestic cat. However, such abilities have been much less studied during ontogeny. In the present study we examined spontaneous quantity discrimination by pre-weaning age kittens in two-way food choice experiments. In Experiment 1, 26 kittens performed 12 trials with different ratios between the number of same-size food items. In Experiment 2, 24 other kittens performed eight trials with different ratios between the size of two food items. We found, in general, that the kittens discriminated between the different amounts of food and spontaneously chose the larger one, but that their choice was influenced by the ratio of difference. The kittens in Experiment 1 chose the larger number of same-size food items if the ratio was smaller than 0.4 and in Experiment 2 they chose the larger pieces of food if the ratio between the items was smaller than 0.5. Because the kittens' choice was not influenced by the absolute number of food items or the numerical difference between them in Experiment 1, it suggests that their cognitive performance relied on an analog magnitude system rather than on an object file system during the quantity discrimination tasks. We discuss our results considering the ecological and social background of cats and compare it with the performance of previously studied species.

RESUMO

This study aimed to investigate the role of the psychological impact of environments rich in palatable foods on three aspects of eating behavior: cognitive restraint (CR), uncontrolled eating (UE), and emotional eating (EE). The hypotheses were as follows: (a) The psychological impact (i.e., motivation to eat) of an environment rich in palatable foods will positively predict CR, UE, and EE; (b) dieting will predict CR, UE, and EE; and (c) CR, UE, and EE will positively predict body mass index (BMI). This study had a cross-sectional design in which data were collected online from 413 subjects. The psychological impact of food-rich environments (food available, food present, and food tasted) was assessed using the Power of Food Scale (PFS), and CR, UE, and EE were assessed using the Three-Factor Eating Questionnaire (TFEQ-R18). Both instruments were tested for confirmatory factor analysis. The relationship between constructs was measured using partial least-square structural equation modeling (PLS-SEM). "Food available" positively predicted all TFEQ-R18 factors (p < 0.01). "Food present" positively predicted UE (p < 0.001) and EE (p = 0.01). People currently on a diet showed higher levels of CR (p < 0.001) and EE (p = 0.02). UE and EE positively predicted BMI. Thus, CR, UE, and EE were positively predicted by the motivation to consume palatable foods in varying proximity, suggesting that the presence of food and, more importantly, its general availability may be important determinants of eating behavior, particularly UE and EE. Health strategies should consider the influence of the food environment to prevent and better manage impairments in eating behavior. Sex differences suggest that special attention should be paid to women. Furthermore, dieting was associated with higher levels of EE, which in turn was associated with higher BMI. Weight loss interventions should consider this vulnerability.

RESUMO

Diets based on meals that provide a large amount of energy and consumed frequently often increase the rate of growth of the body mass index (overweight or obesity) and, in turn, the risk of suffering from non-communicable diseases. In order to make a food choice, it is necessary to search for foods in the environment, taking into account physical and social variables (contextual variables) which, together with individual variables, delimit the situation of food selection. The objective of this study was to evaluate the effect of social facilitation, portion size, salience of food, and food preference or rejection on the selection of energy-dense foods by young college students. To do so, we performed a factorial experiment in which unaccompanied and accompanied participants (levels of social facilitation) as they went through the process of choosing from different options of main dishes, beverages, and desserts then noted the reasons for their selection (preference or rejection of the food). Results showed significant differences between the group of accompanied participants and salience of food in the selection of the energy-dense main dishes and desserts (pizza, spaghetti, and chocolate cake). A significant relationship was also identified between accompanied participants, hedonistic/sensory reasons (food preference or rejection category), and salience of food in the selection of the energy-dense main dishes. In conclusion, key findings of the variables that constitute the situation that predicts the selection of energy-dense foods have emerged from this study, when participants and the given level of social facilitation (in this case, being accompanied) were faced with the conditions of the food salience of the meals of their preference regarding its taste and appearance.

RESUMO

A large body of evidence assessing the effectiveness of front-of-package (FOP) nutrition labeling exists. Most experimental studies have been conducted with fictitious products. However, consumers' perception depends on several products extrinsic factors such as brand. Understanding how strong brand associations influence the effectiveness of FOP nutrition labeling schemes may be crucial to informing policymaking. In this context, the aim of this work was to evaluate the effect of five different variants of nutritional warnings labels (black magnifier, red magnifier, black octagon, black triangle, and red circle) on consumers' choice of commercial products, compared with two FOP nutrition labeling schemes: the guidelines daily amounts (GDAs) system and the traffic light system (TLS). An online randomized controlled trial with 1,932 participants was used to evaluate the effect of FOP nutrition labeling on participants' choices in eight sets of three commercial products, available in the Brazilian marketplace. A multinomial logistic regression model was used to evaluate the influence of FOP nutrition labeling on participants' likelihood of selecting the different products in the choice task. Results showed that nutritional warnings and the TLS significantly increased the likelihood of selecting none of the products instead of the least healthful product, or a healthier product, in at least one of the product categories compared with the GDA. Warnings tended to have a larger effect, suggesting their potential to encourage healthier food choices.

RESUMO

Nutritional warnings (NWs) as a front-of-package label were implemented as a public policy aiding consumers with recognizing processed foods with high levels of critical nutrients (sodium, saturated fats, carbohydrates, and calories). However, in spite of this tool being well positioned in consumer decision making, there is little extant knowledge about the relationship between the message sent by NW, nutritional knowledge, consumer motivation, and the intention to avoid consuming processed foods. To understand these dimensions' relations, a theoretical model was created and subsequently tested through structural equations. We applied a survey to 807 home food purchasing decision makers. The results show that the direct effect of NW messages raises the intention to avoid processed foods, while eating motivation is negative in its direct effect on the same avoidance intention. However, the message sent by NWs had a mediating effect between the intentions to avoid processed food and eating motivation but showed no such effect on nutritional knowledge. This suggests that the message sent by NWs was able to turn negative eating motivation into positive eating motivation to avoid processed foods. In conclusion, NWs help mitigate eating motivations, as well as boost the intention to avoid processed foods.

RESUMO

The objective of the present study was to analyze a nopal beverage (Opuntia ficus-indica) as a non-traditional food, considering its sensory properties, expectations, experiences, and emotions of low-income and food-insecure Brazilian potential consumers. The study was carried out in two main stages. First, the sensory appeal of a nopal beverage was evaluated before and after tasting with expected and actual sensory characterization, respectively, distributed into three different groups: Control, Advantages, and Inconveniences. Secondly, a Food Choice Questionnaire (FCQ) was applied to learn more about expectations, experiences, and emotions involved in the food pattern of this population. The expected sensory properties for the Inconveniences group showed the lowest grades for all variables, mainly compared to the Advantages group, which showed a difference of 21.98% for nutritious, 16.47% for overall liking, and 55.13% for acceptance. However, after tasting in the Inconveniences group, the acceptance changed from "I would hardly ever eat this" to "I would frequently eat this". In a similar way, the overall liking had an increase of 25.35% from before to after tasting. The interrelationship between the socio-economic characteristics and the treatments revealed significant effects for education level, household income, and gender on the beverage acceptance. The Multiple Factor Analysis showed how socio-demographic aspects impact emotions. For the majority of participants, the attribute they are most concerned about when choosing a food is that it needs to fill them (satisfy their hunger). Therefore, this is the first study of its kind in Brazil, and the results provide good insights on factors that influence food choices of low-income and food-insecure Brazilian potential consumers.

RESUMO

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

Introduction: Unhealthy food choices increase the risk of obesity and its co-morbidities. Nutrition labels are a public health policy that aims to drive individuals toward healthier food choices. Chile has been an example of this policy, where mandatory nutrient warning labels (NWL) identify processed foods high in calories and critical nutrients. Eating contexts influence individual food choices, but whether eating contexts also influence how NWL alter the decision process and selection during food choice is unknown. Methods: In an online mouse-tracking study, participants prompted to health, typical, or unrestricted eating contexts were instructed to choose between pairs of foods in the presence or absence of NWL. Conflict during choices was analyzed using mouse paths and reaction times. Results: NWL increased conflict during unhealthy food choices and reduced conflict during healthy choices in all contexts. However, the probability that NWL reversed an unhealthy choice was 80% in a healthy, 37% in a typical, and 19% in an unrestricted context. A drift-diffusion model analysis showed the effects of NWL on choice were associated with an increased bias toward healthier foods in the healthy and typical but not in the unrestricted context. Discussion: These data suggest that the efficacy of NWL to drive healthy food choices increases in a healthy eating context, whereas NWL are less effective in typical or unrestricted eating contexts.

RESUMO

Food choice for children has important implications in establishing early-life dietary habits and preferences. Food choice for children has been studied as parent-child dyad dynamics, but little is known about the extended system of relationships in maternal food choice for children. The objective of this study was to understand the functions of mothers' social networks in the food choices that mothers make for their children ages 1 to 5 years old in rural Mexico. In-depth interviews were conducted with 46 participants in three rural communities. The interviews inquired about participants' child-feeding practices, personal and local beliefs about child feeding and the individuals with whom they had conversations about food and child feeding. All interviews were conducted in Spanish, audio-recorded, transcribed verbatim, verified for quality and analysed using the constant comparative method. Five interconnected networks emerged, consisting of household family, non-household family, community, children's initial school and health and nutritional programme personnel. Each network had functions in food choice that ranged from shared food decision-making in the household family network to imparting formal dietary guidance in the health and nutritional programme personnel network. Across the networks, professionals, participants' mothers and mothers-in-law, community senior women and other women with children emerged as prominent figures whom participants would turn to for child-feeding advice. These findings provide empirical evidence that social networks, as an organized system of interconnected relationships, have vital functions in establishing social norms for food choices made for children that can be leveraged to promote healthy food choices.

RESUMO

The orexin peptides promote hedonic intake and other reward behaviors through different brain sites. The opioid dynorphin peptides are co-released with orexin peptides but block their effects on reward in the ventral tegmental area (VTA). We previously showed that in the paraventricular hypothalamic nucleus (PVN), dynorphin and not orexin peptides enhance hedonic intake, suggesting they have brain-site-specific effects. Obesity alters the expression of orexin and dynorphin receptors, but whether their expression across different brain sites is important to hedonic intake is unclear. We hypothesized that hedonic intake is regulated by orexin and dynorphin peptides in PVN and that hedonic intake in obesity correlates with expression of their receptors. Here we show that in mice, injection of DYN-A1-13 (an opioid dynorphin peptide) in the PVN enhanced hedonic intake, whereas in the VTA, injection of OXA (orexin-A, an orexin peptide) enhanced hedonic intake. In PVN, OXA blunted the increase in hedonic intake caused by DYN-A1-13. In PVN, injection of norBNI (opioid receptor antagonist) reduced hedonic intake but a subsequent OXA injection failed to increase hedonic intake, suggesting that OXA activity in PVN is not influenced by endogenous opioid activity. In the PVN, DYN-A1-13 increased the intake of the less-preferred food in a two-food choice task. In obese mice fed a cafeteria diet, orexin 1 receptor mRNA across brain sites involved in hedonic intake correlated with fat preference but not caloric intake. Together, these data support that orexin and dynorphin peptides regulate hedonic intake in an opposing manner with brain-site-specific effects.

RESUMO

As consumer awareness of food expands, as does the understanding of the correlation between nutrition and health benefits, consumers are increasingly looking for healthier foods. One of these aspects can be observed in the search for foods with clean labels and with the removal/replacement of artificial additives, such as coloring. However, there are still no studies on the perception of foods with a positive reputation, such as fermented dairy. The present work aimed to evaluate the consumers' perception (n = 121) of kefir labels with the addition of food dyes from different origins (KN = natural kefir / no dye; KCA = kefir added with artificial coloring; KCN = kefir added with natural coloring; KCR = kefir added with coloring from fruit residues), associating data obtained through Product Personality Profile (PPP) and the Food Choice Questionnaire (FCQ). Based on FCQ's data, consumers were subdivided into three distinct clusters with specific profiles - Conscious, Balanced, and Flexible - and had their perceptions of each of the kefir labels described by PPP and Multidimensional Alignment Analysis (MDA). By consensus, the groups associated the KN label with individuals concerned about healthy eating and diets, reaffirming the positive commercial positioning of kefir. At the same time, for KCA, a contrasting association was observed. The Conscious group noted the samples better, emphasizing the correlation of KCR (with added fruit residue dye) with an adult female, married and engaged in physical activity. KCN was correlated with a young, single, student and gym or running target group stands out for the Balanced group. The Flexible one also associated the consumption of KCA with a young audience, ranging from athletic to overweight, with a normal to unbalanced diet. In summary, different impacts on the perception of kefir labels could be elicited with the correlation of FCQ, PPP, and MDA, emphasizing the importance of exploring market segments and design strategies for the target audience.

RESUMO

The Coronavirus disease (COVID-19) rapidly expanded throughout the world affecting human life in the health, social, cultural, economic and environmental aspects. On an international scale, some works have addressed the importance of the agri-food topic during the pandemic, especially about food consumption. The Mexican case is particularly relevant since it is the country with the highest proportion of overweight people. The objective of this work was to know the choices and consumption of foods in Mexican households during the period of maximal contingency. An on-line questionnaire was responded by 867 volunteers who answered about the aspects taken in consideration in their food consumption, the changes in the consumption of certain foods and the socioeconomic and health aspects of the family. Four groups were identified: "Budget consumers", "Hedonics", "Price conscious" and "Conscious". Changes in the attitudes to food are not related to the health state, overweight, or family size; but are related to income level of households and above all, to the education level. Results show an opportunity to change for healthier food habits in Mexico, mainly in the most vulnerable sectors.

RESUMO

The coronavirus pandemic started a worldwide emergency, and tight preventive actions were necessary to protect the population, changing individuals' daily habits. Dwelling and working at home can change dietary habits, affect food choice and access, as well as the practice of physical activity. In this regard, this study's goal was to compare eating competence (EC) among Brazilian adults before and during the coronavirus pandemic, using the Brazilian version of the eating competence Satter inventory (ecSI2.0™BR) with the "retrospective post-then-pre" design. This cross-sectional study was performed from 30 April to 31 May 2021 among a convenience sample of the Brazilian adult population using an online platform (Google® Forms). In the studied sample (n = 302 in which 76.82% were females), EC total score lowered during the pandemic (31.69 ± 8.26 vs. 29.99 ± 9.72; p < 0.005), and the decrease was worst after the beginning of the pandemic among those who reported weight gain, decreased the consumption of fruit and vegetables, and increased the consumption of sugary beverages. The contextual skill component seems relevant in this scenario, where our life and routines were changed entirely, demonstrating that the ability to manage the food context is essential, especially when sanitary and economic situations represent a new challenge.

RESUMO

RESUMEN En el actual contexto de transición nutricional es necesario explorar los factores que afectan la elección de alimentos en la población peruana, por ello el objetivo del estudio fue validar el instrumento Food Choice Questionnaire (FCQ) en Lima Metropolitana. Se realizó un estudio de corte transversal para validar el instrumento FCQ diseñado por Steptoe. Se desarrollaron 4 etapas: revisión del FCQ y adecuación al español, validación semántica y de contenido con expertos, validación de constructo utilizando el análisis factorial de componentes principales y análisis de fiabilidad con el Alfa de Cronbach. Los resultados de la validez semántica y de contenido permitieron obtener un instrumento modificado agregándose el factor "Entorno social". En la validación de constructo se realizó un análisis factorial y luego de 4 iteraciones se depuraron 7 ítems resultando un instrumento con 10 factores y 36 ítems, que respondían al 62,6% de la varianza; posteriormente con los resultados del análisis de fiabilidad, el cuestionario FCQ se redujo a 8 factores y 32 ítems. En conclusión, se obtuvo una versión validada del cuestionario FCQ para ser utilizado en población de 18 a 29 años de la capital del Perú. El cuestionario validado consta de 8 factores incluyéndose el "Entorno social". Son necesarios otros estudios en diferentes regiones y grupos poblacionales para recoger nuevos factores que influyen en la elección de alimentos.

ABSTRACT In the current nutrition transition context, the exploration of associated factors with food choices in the Peruvian population is necessary; therefore the study's objective was to validate the Food Choice Questionnaire (FCQ) in Metropolitan Lima. A cross-sectional design was conducted to validate the FCQ instrument designed by Steptoe. It was developed in 4 stages: FCQ's review and adaptation to Spanish, semantic and content validation with experts, construct validity using factorial analysis of principal components, and reliability analysis using Cronbach's Alpha. The results of the semantic and content validity produced a modified instrument with one "social environment" factor and 6 more items. For construct validity, a factorial analysis was performed and after 4 iterations, 7 items were removed, resulting an instrument with 10 factors and 36 items, which explained 62.6% of the variance. Finally, with the results of the reliability analysis, the FCQ questionnaire was reduced to 8 factors and 32 items. In conclusion, a validated version of the FCQ questionnaire was obtained to be used in 18 to 29 years old population of the capital city of Peru. The questionnaire validated consists of 8 factors including the "social environment". Other studies in different regions and population groups are necessary to collect new factors that influence food choices.

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.

RESUMO

Everyday consumer food choices are influenced by a variety of interacting biological, situational, economical, and psychological factors [1], [2], [3], [4]. The choice between animal-based and plant-based protein has implications for overall and cause-specific mortality and cardiometabolic health (e.g. [5], [6], [7], [8], [9]). During laboratory experiments that are designed to better understand factors that influence protein choice specifically, controlling for the sensory aspects of stimuli, health information, consumers' physical characteristics, and dietary preferences is crucial. To illustrate the point, if a choice task included two stimuli, brown rice with tofu and steak with fries for example, a variety of factors, such as visual appeal and hedonic attributes could influence protein choice and dilute the effect of the experimental manipulation. This article provides a template for a generic experiment to measure participant choice among salt-cured jerky protein sources (e.g. beef, salmon, soy, textured vegetable protein, turkey, tuna) and consumed amounts. Using jerky products as stimuli minimizes variance in visual appearance, texture, and nutritional values, therefore facilitating the attribution of the experimental factor(s). A list of methods to experimentally and/or statistically control for potential sources of measurement error is provided.•Consumer choice of animal vs. plant-based protein has implications for individual and environmental health.•The methods can be used to customize experiments in consumer behavior research, psychology, and nutrition sciences.•Food choice is influenced by a variety of factors; experimentally and/or statistically controlling for major sources of measurement error increases confidence in the effect of the manipulated variable.
