The role of psychosocial well-being and emotion-driven impulsiveness in food choices of European adolescents.

BACKGROUND: It is unclear whether a hypothetical intervention targeting either psychosocial well-being or emotion-driven impulsiveness is more effective in reducing unhealthy food choices. Therefore, we aimed to compare the (separate) causal effects of psychosocial well-being and emotion-driven impulsiveness on European adolescents' sweet and fat propensity. METHODS: We included 2,065 participants of the IDEFICS/I.Family cohort (mean age: 13.4) providing self-reported data on sweet propensity (score range: 0 to 68.4), fat propensity (range: 0 to 72.6), emotion-driven impulsiveness using the UPPS-P negative urgency subscale, and psychosocial well-being using the KINDLR Questionnaire. We estimated, separately, the average causal effects of psychosocial well-being and emotion-driven impulsiveness on sweet and fat propensity applying a semi-parametric doubly robust method (targeted maximum likelihood estimation). Further, we investigated a potential indirect effect of psychosocial well-being on sweet and fat propensity mediated via emotion-driven impulsiveness using a causal mediation analysis. RESULTS: If all adolescents, hypothetically, had high levels of psychosocial well-being, compared to low levels, we estimated a decrease in average sweet propensity by 1.43 [95%-confidence interval: 0.25 to 2.61]. A smaller effect was estimated for fat propensity. Similarly, if all adolescents had high levels of emotion-driven impulsiveness, compared to low levels, average sweet propensity would be decreased by 2.07 [0.87 to 3.26] and average fat propensity by 1.85 [0.81 to 2.88]. The indirect effect of psychosocial well-being via emotion-driven impulsiveness was 0.61 [0.24 to 1.09] for average sweet propensity and 0.55 [0.13 to 0.86] for average fat propensity. CONCLUSIONS: An intervention targeting emotion-driven impulsiveness, compared to psychosocial well-being, would be marginally more effective in reducing sweet and fat propensity in adolescents.

Gender differences in adolescent food preferences and their association with parent food preferences: data from the China Health and Nutrition Survey (CHNS).

PURPOSE: Food preference is an important factor that affects one's eating behavior and dietary intake. Parent food preferences and food choices may influence children food preferences. This study is aimed to describe gender differences and time trends of Chinese adolescent food preferences and to explore the association between adolescent and their parent food preferences. METHODS: The data were drawn from four waves of the China Health and Nutrition Survey (CHNS) conducted between 2006 and 2015. Participants were asked to indicate their degree of preferences for five food categories (fast food, salty snack food, fruits, vegetables, and soft/sugary drinks) using a 5-point Likert scale (from "dislike very much" to "like very much"). Logistic regression was performed to determine the association of food preferences between adolescents and their parents. RESULTS: Adolescent preferences for unhealthy foods were significantly higher than those of adults. Adolescent food preferences for fruits and vegetables decreased slightly over nine years, and there were gender differences in healthy food preferences (girls > boys, P < 0.05). Regardless of boys or girls, adolescent food preferences for healthy foods (fruits and vegetables) were significantly associated with both their fathers (OR: 3.64-4.58 for boys and 2.71-4.39 for girls) and mothers (OR: 2.13-4.11 for boys and 3.07-5.66 for girls) food preferences. For fast food and salty snack food preferences, boys appeared to be influenced greater by their fathers than girls, while girls appeared to be influenced greater by their mothers than boys. CONCLUSIONS: The present study reveals a high degree of unhealthy food preferences among Chinese adolescents and a gender-specific association of fast food and salty snack preference between Chinese adolescents and their parents. Our results may be useful for interventions to reduce adolescent unhealthy food preferences and intakes.

Dietary taste patterns and diet quality of female nurses around the night shift.

PURPOSE: Night shift workers are at risk of making poor food choices: e.g. sleep deprivation may lead to higher food intake with innate preferred tastes, such as sweet, savoury and fatty foods. Therefore, better insight in dietary taste patterns of night shift workers may improve the understanding of their food choices. METHODS: This observational study assessed dietary taste patterns of 120 female night shift working nurses and compared them to 307 women of a reference population. Dietary intake, assessed with 24-h dietary recalls, was combined with a taste intensity database, including taste profiles of 557 foods. The contribution to the daily intake of 6 taste clusters was assessed: fat, neutral, sweet/fat, sweet/sour, salt/umami/fat and bitter. RESULTS: During night shifts, nurses consumed a significantly higher energy percentage (en%) of 'neutral' (5.9 en%), 'sweet/sour' (8.1 en%) and 'sweet/fat' (6.5 en%) tasting foods and a lower en% of 'fat' (- 17.1 en%) and 'bitter' (- 2.1 en%) tasting foods than outside the night shift. They consumed a larger en% from foods with a 'sweet/sour' (1.9 en%) taste and a lower en% from foods with a 'bitter' (- 2.1 en%) taste than the reference population, irrespective of age, BMI and smoking status. A higher en% and gram% of 'fat' tasting foods and a higher gram% 'fat/salt/umami' tasting foods were associated with lower diet quality. CONCLUSION: Our results only partly support our hypothesis that nurses would select foods with more innate taste preferences. In addition, fat and savoury tasting foods were negatively associated with their diet quality.

You eye what you eat: BMI, consumption patterns, and dieting status predict temporal attentional bias to food-associated images.

People know that overconsumption of high-fat high-sugar (HFHS) foods have negative consequences for physical and cognitive wellbeing but continue to consume these foods in excess, leading to recent proposals to model obesity as an addiction disorder. The current experiment tested, in a large undergraduate sample (N = 306), the hypothesis that obesity and overconsumption is linked with an oversensitivity to rewards that drives attentional biases towards foods and food-associated cues. Using a modified emotion-induced blindness task with food-related distractors, we examined the extent to which attentional biases to images of HFHS foods were accounted for by BMI, HFHS food intake, self-reported hunger, time since last meal, diet status, food preferences, and attentional control. We also examined whether the same individual differences predicted attentional priority to cues that have a learned association with HFHS foods (i.e., images of food logos). Contrary to our predictions, higher BMI predicted less attentional priority for images of food and food logos. At the same time, increased consumption of HFHS foods predicted increased attentional priority for food images, whereas dieting predicted increased attentional priority for food logo images. Our results suggest that different people may preferentially attend to food versus food logo imagery based on their relationships with food. More broadly, our results support the theoretical perspective that attentional biases to food-associated stimuli can be affected by various competing, state-related factors.

Clean-label products: Factors affecting liking and acceptability by Portuguese older adults.

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.

Consumer susceptibility to front-of-package (FOP) food labeling: Scale development and validation.

Current research in food science has explored the influence of front-of-package (FOP) labeling systems on consumer decision-making, yielding mixed results. We suggest that these inconsistent findings regarding FOP labeling effectiveness stem from a failure to consider a pivotal individual-level variable: consumer susceptibility to FOP labeling (CSFL). In the present research, we define this focal construct and develop and psychometrically validate a seven-item instrument that captures the construct across six studies (N = 1134). The current research may assist in segmenting consumers based on their susceptibility to FOP labeling, thereby facilitating the creation of targeted interventions tailored to this individual difference. Notably, the CSFL scale is positively correlated with consumers' willingness to purchase food items with genuine, third-party FOP labels, but not products lacking labels or products with fictitious FOP labels. This supports the predictive validity of the scale in determining important consumption-related outcomes.

Does presbygeusia really exist? An updated narrative review.

This review critically assessed the existence of presbygeusia, i.e., the impairment in taste perception occurring in the elderly, as a natural part of the aging process and its potential clinical implications. Several factors might contribute to age-related taste alterations (TAs), including structural changes in taste buds, alterations in saliva composition, central nervous system changes, and oral microbiota dysbiosis. A comprehensive literature review was conducted to disentangle the effects of age from those of the several age-related diseases or conditions promoting TAs. Most of the included studies reported TAs in healthy elderly people, suggesting that presbygeusia is a relatively frequent condition associated with age-related changes in the absence of pathological conditions. However, the impact of TAs on dietary preferences and food choices among the elderly seems to be less relevant when compared to other factors, such as cultural, psychological, and social influences. In conclusion, presbygeusia exists even in the absence of comorbidities or drug side effects, but its impact on dietary choices in the elderly is likely modest.

Neural correlates of changing food choices while bypassing values.

Current theories suggest that altering choices requires value modification. To investigate this, normal-weight female participants' food choices and values were tested before and after an approach-avoidance training (AAT), while neural activity was recorded during the choice task using functional magnetic resonance imaging (fMRI). During AAT, participants consistently approached low- while avoiding high-calorie food cues. AAT facilitated low-calorie food choices, leaving food values unchanged. Instead, we observed a shift in indifference points, indicating the decreased contribution of food values in food choices. Training-induced choice shifts were associated with increased activity in the posterior cingulate cortex (PCC). In contrast, the medial PFC activity was not changed. Additionally, PCC gray matter density predicted individual differences in training-induced functional changes, suggesting anatomic predispositions to training impact. Our findings demonstrate neural mechanisms underlying choice modulation independent of valuation-related processes, which has substantial theoretical significance for decision-making frameworks and translational implications for health-related decisions resilient to value shifts.

Study protocol of the sweet tooth study, randomized controlled trial with partial food provision on the effect of low, regular and high dietary sweetness exposure on sweetness preferences in Dutch adults.

BACKGROUND: Several health organizations recommend lowering the consumption of sweet-tasting foods. The rationale behind this recommendation is that a lower exposure to sweet foods may reduce preferences for sweet tasting foods, thus lowering sugar and energy intake, and in turn aiding in obesity prevention. However, empirical data supporting this narrative are lacking. In fact, relatively little is known about the contribution of long-term sweet taste exposure on one's sweetness preferences. METHODS: The primary objective of this randomized controlled trial is to assess the effect of low, regular and high dietary sweetness exposure on preference for sweet foods and beverages, and to compare these effects between intervention groups. One hundred and eighty adults aged 18-65 years with a BMI of 18.5-30.0 kg/m2 will be recruited and randomly allocated to either: low dietary sweetness exposure (LSE) (10-15% daily energy from sweet tasting foods), regular dietary sweetness exposure (RSE) (25-30% daily energy from sweet tasting foods), or high dietary sweetness exposure (HSE) (40-45% daily energy from sweet tasting foods), for 6 months, followed by a 4-month follow up. Intervention foods are provided ad libitum, covering approximately 50% of the daily number of food items, to include sugar-sweetened, low-calorie-sweetener-sweetened and non-sweet foods. The primary outcome measure is the difference in change in sweetness preference from baseline to 6 months between intervention groups. Secondary outcomes include: change in sweet taste preferences at different time-points; taste intensity perception; behavioral outcomes: food choice and intake, sweet-liker type, food cravings, dietary taste preferences and dietary taste patterns; anthropometric outcomes: body composition, waist-hip circumference, body weight; and biochemical outcomes: glucose variability and biomarkers related to CVD and diabetes. DISCUSSION: This study will generate important data on the effect of dietary sweetness exposure on sweetness preferences in terms of effect size and change, duration of change and its impact on food intake, body weight status and associated health outcomes. TRIAL REGISTRATION: The study protocol has been registered on ClinicalTrials.gov (ID no. NCT04497974, Registered 4 August 2020, https://clinicaltrials.gov/ct2/show/NCT04497974 ) and approved by Wageningen's Medical Ethical Committee (ABR no. NL72134).

PECULIARITIES OF EATING BEHAVIOR IN CHILDREN WITH AUTISTIC SPECTRUM DISORDERS.

OBJECTIVE: The aim: To determine of the nutrition peculiarities in children with ASD. PATIENTS AND METHODS: Materials and methods: The study involved 37 children with ASD from 2 -12 years and thier mothers, in according to reveal its disorder effect on the clinical course of ASD in children. RESULTS: Results: It was shown role of irrational nutrition of the mother during pregnancy, peculiarities of family food traditions, problems of breastfeeding and com-plementary feeding. Eating behavior of mothers during pregnancy were: monotonous nutrition and an inadequate diet. The family food preferences were: varied and included both traditional and specific food preferences ( vegan, vegeterian, monotony diet). CONCLUSION: Conclusions: The analysis of the eating behavior in the ASD children, taking into account the age peculiarities, was carried out. Intolerance to certain products was noted. Also effectiveness of the elimination diet was shown. Elimination from the diet of the white flour products within 6 months has a positive result which evaluated by digestive and cognitive signs.

Food Intake Following Gastric Bypass Surgery: Patients Eat Less but Do Not Eat Differently.

BACKGROUND: Lack of robust research methodology for assessing ingestive behavior has impeded clarification of the mediators of food intake following gastric bypass (GBP) surgery. OBJECTIVES: To evaluate changes in directly measured 24-h energy intake (EI), energy density (ED) (primary outcomes), eating patterns, and food preferences (secondary outcomes) in patients and time-matched weight-stable comparator participants. METHODS: Patients [n = 31, 77% female, BMI (in kg/m2) 45.5 ± 1.3] and comparators (n = 32, 47% female, BMI 27.2 ± 0.8) were assessed for 36 h under fully residential conditions at baseline (1 mo presurgery) and at 3 and 12 mo postsurgery. Participants had ad libitum access to a personalized menu (n = 54 foods) based on a 6-macronutrient mix paradigm. Food preferences were assessed by the Leeds Food Preference Questionnaire. Body composition was measured by whole-body DXA. RESULTS: In the comparator group, there was an increase in relative fat intake at 3 mo postsurgery; otherwise, no changes were observed in food intake or body composition. At 12 mo postsurgery, patients lost 27.7 ± 1.6% of initial body weight (P < 0.001). The decline in EI at 3 mo postsurgery (-44% from baseline, P < 0.001) was followed by a partial rebound at 12 mo (-18% from baseline), but at both times, dietary ED and relative macronutrient intake remained constant. The decline in EI was due to eating the same foods as consumed presurgery and by decreasing the size (g, MJ), but not the number, of eating occasions. In patients, reduction in explicit liking at 3 mo (-11.56 ± 4.67, P = 0.007) and implicit wanting at 3 (-15.75 ± 7.76, P = 0.01) and 12 mo (-15.18 ± 6.52, P = 0.022) for sweet foods were not matched by reduced intake of these foods. Patients with the greatest reduction in ED postsurgery reduced both EI and preference for sweet foods. CONCLUSIONS: After GBP, patients continue to eat the same foods but in smaller amounts. These findings challenge prevailing views about the dynamics of food intake following GBP surgery. This trial was registered as clinicaltrials.gov as NCT03113305.

Adult rats from undernourished dams show sex-dependent impaired expression in taste papillae and hypothalamus of genes responsible for sweet and fat detection and signalling.

AIM: Individuals undernourished in utero or during early life are at high risk of developing obesity and metabolic disorders and show an increased preference for consuming sugary and fatty food. This study aimed at determining whether impaired taste detection and signalling in the lingual epithelium and the brain might contribute to this altered pattern of food intake. METHODS: The preference for feeding fat and sweet food and the expression in circumvallate papillae and hypothalamus of genes coding for sweet and fat receptors and transducing pathways were evaluated in adult rats born to control or calorie-restricted dams. Expression in the hypothalamus and the brain's reward system of genes involved in the homeostatic and hedonic control of food intake was also determined. RESULTS: Male and female undernourished animals exhibited increased expression in taste papillae and hypothalamus of T1R1, T1R2, CD36, gustducin, TRMP5 and PLC-ß2 genes, all of which modulate sweet and fat detection and intracellular signalling. However, the severity of the effect was greater in females than in males. Moreover, male, but not female, undernourished rats consumed more standard and sweetened food than their control counterparts and presented increased hypothalamic AgRP and NPY mRNAs levels together with enhanced dopamine transporter and dopamine receptor D2 expression in the ventral tegmental area. CONCLUSIONS: Maternal undernutrition induces sex-specific changes in food preferences and gene expression in taste papillae, hypothalamus and brain reward regions. The gene expression alterations in the male offspring are in line with their preference for consuming sugary and fatty food.

Drivers of food choice among women living in informal settlements in Nairobi, Kenya.

Suboptimal diets drive the multiple burdens of malnutrition among women living in informal settlements. Women's food choices have important implications for their health, as well as that of their families. The purpose of this study was to examine how food choice decisions might differ across different age groups of women living in informal settlements in Nairobi, Kenya. Using in-depth interviews which incorporated a free-listing task, we determined the factors influencing food choice decisions in women in two informal settlements, Kibera and Mukuru. Among women in all age groups, we found income and food price to be the most salient factors influencing food choice decisions. Differences across age groups regarding food choice considerations included individual preference and quality being more salient factors amongst younger women while household preferences were more salient among older women. Women also reported making trade-offs between food affordability and other factors including time and nutrition, which led to sub-optimal diets. Our findings suggest that interventions in these settings may need to be tailored to specific age groups. Additionally, interventions may need to target both individual factors and the external food environment to help women overcome the trade-offs they often find themselves making in food choice decisions.

The effect of parental food neophobia on children's fruit and vegetable consumption: A serial mediation model.

Children in the United States do not consume the recommended amounts of healthful foods such as fruits and vegetables. In order to investigate factors associated with children's fruit and vegetable consumption, we used serial mediation models based on a theoretical model proposed by Kaar et al., [Food Quality & Preference, 50, 57-64 (2016)] to assess the indirect effect of parental food neophobia (X) on children's consumption (Y) of fruits and vegetables through two serial mediators, variety of fruits and vegetables offered at home (variety offered; M1) and child food neophobia (M2). This was accomplished with a sample of 148 children between 5 and 10 years of age (Mage = 7.71 years, 44.7% female). We measured parental and child food neophobia and parents' reports of the frequency with which they regularly offered a variety of fruits and vegetables. In addition, children completed a laboratory task in which they were presented with four different fruits and vegetables and were asked to try the foods. Analyses revealed a significant indirect effect of parents' food neophobia on consumption of fruits and vegetables through variety offered (M1) and child food neophobia (M2). There was also a significant serial indirect effect of parent food neophobia on consumption through variety offered and child food neophobia. The results provide further evidence to support the contention that parent and child neophobia and the feeding environment exert a strong influence on children's fruit and vegetable consumption.

Social media's influence on adolescents' food choices: A mixed studies systematic literature review.

Over 90% of adolescents have at least one social media account, and their presence on social media continues to grow. Food and beverage brands capitalize on this trend by marketing their products on social media to adolescents. Depending on the nutrition value of the products being marketed, social media advertisements' influence may contribute to the risk of developing unfavorable health outcomes such as obesity, hypertension, and type 2 diabetes. This review aimed to investigate social media's food and beverage advertisements' role in influencing adolescents' food choices by appraising published literature. A systematic literature review was conducted reporting on social media's role in adolescents' food choices. Articles were searched through CINAHL and PubMed from scholarly journals between 2015 and 2020, using the search terms: social media use, food advertisements, adolescents, and food choices. Eligible articles were selected based on inclusion criteria. PRISMA guidelines were followed, and study quality was assessed using the Mixed Methods Appraisal Tool. The analysis was conducted using narrative analysis to identify key findings. Of the 234 records, six articles met inclusion criteria. The studies revealed two major findings: adolescents were more likely to recall unhealthy food and celebrity influence was a common component of the advertisements. This review suggests that food and beverage companies use social media for marketing their products by targeting the adolescent population. The use of celebrities and influencers and the promotion of "unhealthy" products appear to be commonly used tactics. With these findings, healthcare professionals should consider screening adolescents routinely for social media use and current eating habits and educating the adolescents, parents, and families about health risk. Additionally, implementing legislation and policies may be beneficial in preventing this exposure.

Association between dietary related factors and central obesity among married women: China Health and Nutrition Survey.

Waist-to-height ratio (WHtR) with a cut-off value of 0.5 has been recognized as an anthropometric indicator of central obesity to predict the risk of the chronic disease. The aim of our study was to identify dietary related risk factors of central obesity based on WHtR. We used cross-sectional data from the China Health and Nutrition Survey (CHNS) in 2011 obtained from 2881 married women aged 19-55. The association of dietary related factors and central obesity was analyzed using binary logistic regression and back-propagation artificial neural network. Overall, central obesity prevalence was 48.4% (1394/2881). Compared to the population of women without central obesity, the population of women with central obesity had an older average age (41.84 ± 6.89 years vs 38.45 ± 7.91 years, P < 0.001), and meanwhile an average lower per capita annual income (13904 ± 15916 CNY vs 16753 ± 19163 CNY, P < 0.001). Our analysis indicated that the score of dietary knowledge (adjusted odds ratio (aOR), 0.956; 95% confidence interval (CI), 0.936-0.976) and the score of food preferences (aOR, 0.961; 95% CI, 0.926-0.997) were significantly associated with lower risk of central obesity; whereas fast food (aOR, 1.002; 95% CI, 1.000-1.003) was associated with higher risk of central obesity. The study showed the score of dietary knowledge (15.5%), fast foods (10.2%), and the score of food preferences (8.8%) were the most important modifiable factors for central obesity. In summary, aging, fast food intake, and lower per capita annual income were positively associated with higher prevalence of central obesity, while higher scores of dietary knowledge and food preferences were negatively correlated. More nutrition education programs should be implemented by the government to strengthen the pro-healthy dietary behaviors.

Do children really eat what they like? Relationships between liking and intake across laboratory test-meals.

Liking plays a primary role in determining what and how much children eat. Despite this, the relationship between liking and intake of foods and beverages served as part of a meal is not often reported, even though pediatric feeding studies frequently collect such data. In addition, few studies have reported on the test-retest reliability of both hedonic ratings and laboratory intake among children. To address these gaps, this study was designed to assess the relationship between children's liking of items at a meal and subsequent intake. 61, 4-6 year-olds were recruited to participate in two identical laboratory sessions where liking of 7 foods (i.e., chicken nuggets, ketchup, potato chips, grapes, broccoli, cherry tomatoes, cookie) and 2 beverages (i.e., fruit punch, milk) was assessed (5-point hedonic scale) prior to ad libitum consumption of the same items at a meal. Spearman's correlations tested the relationship between liking and intake and intra-class correlations assessed inter-session reliability of both measures. Liking for potato chips (p < 0.01), grapes (p < 0.05), cherry tomatoes (p < 0.001), and fruit punch (p < 0.001) was positively associated with amount consumed, but no associations were found between liking and intake of other meal items. For the majority of meal items, test-retest reliability of liking and intake were significant (ranging from 0.34 for cookies to 0.93 for tomatoes). At a multi-component meal, children's hedonic ratings were both reliable and modestly predictive of subsequent intake, and the relationships were stronger for lower energy, less well-liked foods. Rather than eating what they like, these data are more consistent with the notion that children do not eat what they dislike.

Emphasizing appeal over health promotes preference for nutritious foods in people of low socioeconomic status.

People of low socioeconomic status (SES) have disproportionately poorer dietary health despite efforts to improve access and highlight the health benefits of nutritious foods. While health-focused labels and advertisements make healthier options easier to recognize, they can prime a number of negative associations about healthy foods (e.g., taste, satiety, cost), which may be particularly aversive for low SES groups. This within-subjects study recruited people of low and high SES (those without and with a college degree) and compared their product expectations, experiences, satiety, and choice when consuming a bottled fruit and vegetable smoothie promoted as pleasurable ("Crave") or as healthy ("Nutralean"). Relative to Nutralean, Crave improved product expectations and behavioral measures of satiety across all participants. However, Crave enhanced expectations, experiences, and product choice more for low SES than high SES participants. Importantly, improvements were achieved without deception of nutritional facts and without decreasing perceived healthiness or increasing perceived cost. These findings identify SES as an important moderator in health-focused promotion and suggest how the rapidly growing healthy food industry can more effectively appeal to low SES groups, contexts which the majority of Americans navigate.

Development of new measures to assess household nutrition security, and choice in dietary characteristics.

The purpose of this study was to preliminarily develop novel self-administered measures to assess nutrition security and choice in dietary characteristics. Measures were piloted in a convenience sample of households at risk for food insecurity in the United States. The survey included the new measures, construct validation variables (household food security, self-reported general health, and dietary variables), and demographic questions. Exploratory factor analysis was used to assess dimensionality, internal (Cronbach's alpha (CA)), and construct validity were assessed (Spearman's correlation). Multivariate logistic regression models were used to assess added utility of the new measures beyond food security measurement. Finally, brief screener versions of the full measures were created. Participants in the analytic sample (n = 380) averaged 45 years old, 71% experiencing food insecurity, 42% with high school diploma or less, 78% were women, and racially/ethnically diverse. Scores for the Household Nutrition Security (CA = 0.85; Mean = 2.58 (SD = 0.87)), Household Healthfulness Choice (CA = 0.79; Mean = 2.47 (SD = 0.96)), and Household Dietary Choice (CA = 0.80; Mean = 2.57 (SD = 0.90)) were positively associated with food security (0.401-0.657), general health (0.194-0.290), fruit and vegetable intake frequency (0.240-0.280), and "scratch-cooked" meal intake (0.328-0.350), and negatively associated with "processed" meal intake (-0.162 to -0.234) and an external locus of nutrition control (-0.343 to -0.366). Further, findings show that the new measures are useful for assessing risk for poor dietary and health outcomes even after controlling for household food security status and sample characteristics. These findings are encouraging and support reliability, construct validity, and utility of these new measures. Following further testing, such as Confirmatory Factor Analysis in future samples, these measures may be used in various applications to contribute to a better understanding of households' limitations for accessing healthful foods and foods that meet their preferences.

Sensory profile and acceptance of maize tortillas by rural and urban consumers in Mexico.

BACKGROUND: Maize tortillas are the staple food of Mexico and their consumption contributes to preserving the gastronomic patrimony and food security of the population. The aim of the present study was to generate a reference sensory profile for different types of tortillas and to evaluate the effect that these sensory characteristics have on consumer liking and how this influences their consumption preferences and purchase intent. Three types of maize tortillas were analyzed: traditional (T1), combined (T2) and industrialized (T3). The samples were characterized using the modified flash profile method. Sensory acceptability and preference tests were conducted on 240 urban and rural consumers. RESULTS: The judges characterized 19 attributes in the tortilla samples, eight of which were also identified by consumers. In the case of traditional tortillas, the matching attributes were maize flavor, color, thickness and moisture. Only rural consumers were able to perceive significant differences between the samples in terms of aroma and taste/flavor. The study has contributed to understanding the complex mechanisms of sensory acceptance through the use of tools that combine qualitative and quantitative data. CONCLUSION: Although 56% of rural and urban consumers prefer traditional tortillas for their sensory characteristics, purchase intent is also affected by socioeconomic, cultural and microbiological factors. © 2021 Society of Chemical Industry.
