RESUMO
Sensory food aversion, an early childhood eating disorder, is a serious, permanent form of picky eating, in which the infant or the child consistently and persistently refuses certain foods based on specific characteristics, following one or more previous aversive experiences. Biological (sensory processing disorder, taste sensitivity) and environmental factors contribute to its development. Due to limited diet, specific dietary deficiencies may occur but weight gain is usually normal. Behavioral problems, anxiety disorder, autism spectrum disorder are often associated. Diagnosis can usually be made based on a detailed history, but further assessment may include pediatric examination, nutritionist consultation, and psychologic and occupational therapy assessment. Treatment is based on parent education and support in order to minimize mealtime battles and anxiety and to think together about strategies for expanding the child's diet and to help them to accept new foods. As part of the interdisciplinary team, the pediatrician's role is to monitor appropriate growth and development, exclude dietary deficiencies or prescribe supplementation if necessary. In our article, the screening and treatment of sensory processing disorder as part of the assessment of eating problems are introduced as an example of good clinical practice at the Early Childhood Eating and Sleep Disorder Outpatient Clinic at the Heim Pál National Institute of Pediatrics. Orv Hetil. 2023; 164(45): 1767-1777.

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.

Overconsumption of red and processed meat is associated with a multitude of negative health outcomes. Previous research shows exposure to advertising messaging can influence dietary behaviors but research on the influence of meat advertising on diet, specifically, is scant. Theoretically informed by the Reasoned Action Approach, the present experiment randomly assigned participants to view a version of a print McDonald's advertisement that included meat imagery (a Big Mac), non-meat imagery (French fries), or no food (just the McDonalds' logo and slogan), which acted as a control. An online survey in the United States included 514 U.S. adults (Mage = 51 years). Participants exposed to meat imagery compared to the non-meat imagery reported a higher desire to eat meat. The meat imagery and control conditions were also significantly associated with increased cognitive accessibility of meat concepts, compared to when respondents were shown the no-meat condition. Desire to eat meat, but not the cognitive accessibility of meat concepts, was significantly associated with attitude, normative pressure, and perceived behavioral control for avoiding eating meat one day per week; these constructs predicted intention and willingness to avoid meat. Results indicate that exposure to meat imagery in advertising does have the potential to influence meat consumption behavior and also has implications for the use of meat imagery in persuasive messaging for public health campaigns.

Biofortification of food crops with iodine is a novel approach to preventing iodine deficiency in humans. The present study analyses the consumer target groups and the market potential of iodine-biofortified fruit and vegetables in Germany. For this purpose, an online survey of 1016 German fruit and vegetable consumers was conducted to investigate the acceptance of different product categories as well as relevant criteria for the market launch. The results show that iodine-biofortified fruit and vegetables are particularly attractive to consumers who purchase at farmers' markets, organic food shops, and farm stores. Out of this group, 39% of consumers rate such iodine-rich foods as very appealing. They attach importance to food that naturally contains iodine and prefer produce from integrated domestic cultivation. With their focus on sustainability and naturalness, this group of consumers clearly differs from typical users of dietary supplements, who are primarily concerned with health benefits. However, overall about 85% of respondents would prefer biofortified fruits and vegetables to supplements to improve their iodine supply. The greatest market potential for iodine-biofortified fruit and vegetables is to be expected in supermarkets, as this is the preferred food shopping location for most consumers. A total of 28% of those who buy here rate the biofortified foods presented as very appealing. Nevertheless, a successful market launch requires that the benefits of the new products are communicated according to the potential consumer group needs.

Limited research has examined athletes' food and health beliefs and decisions and the congruence of these decisions with recommendations from nutrition professionals. This study aimed to improve understanding of athletes' food-related beliefs and practices to enable nutrition professionals to more effectively enhance performance while protecting athletes' health. Division I college athletes (n = 14, 64% female) from a variety of sports were recruited to participate in 20-min semi-structured phone interviews about food and nutrition-related behaviors and cognitions. Data were content analyzed to identify themes and trends. Prominent factors influencing athletes' food choices were potential benefits to health and performance, availability of foods, and recommendations from sports dietitians. Foods commonly consumed by athletes, including fruits, vegetables, and lean protein, were generally healthy and aligned with sports nutrition recommendations. Athletes avoided energy-dense nutrient-poor foods, such as fast food and fried foods, with the goal of improving performance. Some athletes took supplements (i.e., multivitamin, iron, protein) on the premise that they would improve health and enhance performance or recovery. While athletes' nutrition behaviors are generally congruent with current recommendations, findings highlighted misconceptions held by athletes related to the benefits of some supplements and the belief that packaged/processed foods were inherently less healthy than other options. Nutrition misconceptions held by athletes and incongruities between athletes' nutrition knowledge and behaviors suggest that dietitians should aim to dispel misconceptions held by athletes and provide additional guidance and information to support athletes' current healthful behaviors to ensure these behaviors extend beyond their college athletic career.

BACKGROUND: In Mexico, coffee activity is mainly carried out in indigenous zones, involving almost one million people. However, local national coffee consumption is low. This article focuses on the analysis of the effect of consumers' expectations as well as some sociodemographic characteristics on the level of liking of Mexican local coffee. Four coffees from three indigenous zones of Hidalgo, Mexico were evaluated using a nine-point hedonic scale. The samples were evaluated under three conditions: (i) blind, no information given to the consumer; (ii) expected, only information given to the consumer; and (iii) informed, giving information and product to the consumer. RESULTS: The difference observed between expected and blind condition was significant (P < 0.005) for the three local coffees evaluated, indicating a negative disconfirmation. The local coffees were less appreciated than expected, since the information about the samples created high hedonic expectations among the consumers. The level of education and the place of residence of consumers had a significant influence on their level of liking. Based on demographic characteristics, three segments were found presenting a different pattern of liking. CONCLUSIONS: Consumers had positive expectations towards the local coffee. The sociodemographic characteristics and aspects related to consumption, particularly the experience with the product, are decisive in the expectations concerning the local product. This investigation can be useful to generate marketing strategies according to the demands and needs of the market, making local products to be valued. © 2020 Society of Chemical Industry.

Introduction: Children with autistic spectrum disorders (ASD) commonly exhibit aberrant tactile, taste, and smell sensitivity to foods. Food transformation that alters the appearance, texture, and temperature of foods is promising for solving this sensitivity problem. Objectives: This study evaluated the effect of physical transformation of fruits and vegetables (FV) to snacks to enhance ASD children's sensory approval for eating them. Design: This was a quasiexperimental design study. It lasted for 4 weeks with three episodes of FV exposure to the ASD children per week. The original condition was conducted in the first and fourth week, while intervention was performed in the second and third week. Settings: Food exposure took place in schools in a quiet room. Subjects: This study recruited 56 ASD children. Intervention: Food transformation constituted changing bananas into ice-cream, zucchinis and sweet potatoes into chips, apples and kiwis into popsicles, and carrots into juice. Outcome Measures: FV acceptance and habitual consumption were measured at baseline and postintervention. Results: ASD children increased their consumption of all FV, but only banana consumption was statistically significant from 55.3 to 78.0 g (p < 0.05). For habitual consumption, parents reported increases in all FV consumption for all three measured fruits and 2 of 3 measures of vegetables (pre vs. post mean for bananas: 2.4 vs. 2.9, apples 2.6 vs. 3.2, kiwis 2.4 vs. 2.9, zucchinis 1.9 vs. 2.5, and sweet potatoes 1.8 vs. 2.4; p < 0.05). Conclusion: Physical changes of foods may improve impaired sensory processing of ASD children to promote their FV acceptance. Project Code: RG 55/2019-2020R.

Objectives: Mindfulness-based interventions (MBIs) have been shown to reduce engagement in disordered eating behaviors, although how these interventions engender change remains unclear. The objective of this exploratory qualitative study was to describe the experiences and perceived attitudinal and behavioral changes of women participating in a mindful eating program. Design: Focus group discussions were held with women participating in a community-based mindful eating program for binge and emotional eating. A semistructured interview guide was used to explore participants' conceptualizations of mindfulness-based attitudinal and behavior change, as related to food, eating, and body image. The focus group discussions were audio-recorded, transcribed, and analyzed using thematic analysis to identify salient concepts. Settings/Location: Focus group discussions were held at the Center for Mindfulness at the University of Massachusetts Medical School (UMMS) (United States). Participants: A sample of nine women who were enrolled in the mindful eating program at UMMS for problems with self-reported binge and/or emotional eating participated in this study. Results: Four themes were constructed that described a process of mindfulness-based behavior change, including (1) Learning Through Self-Awareness, (2) Self-Empowerment, (3) Mindful Choice-Making, and (4) Resilient Self-Care. An overarching description of the participants' perceived attitudinal and behavior changes was developed: "unforced freedom of choice, emerging from embodied awareness." Conclusions: These findings suggest that MBIs reduce may disordered eating behaviors through empowering women to make positive choices about food, eating, and coping, without focusing on weight control. Future research is needed to examine whether these findings replicate in larger and more diverse samples, and how they can be used to optimize and implement eating-specific MBIs in community-based settings.

Food sensory imagery - creating a vivid mental image of the sensory experience of eating - can lead to the selection of smaller portions because it serves as a reminder that eating enjoyment does not necessarily increase with portion size. The evidence is mostly limited to adults and to energy-dense foods for which it is particularly difficult to predict the satiating effects of consumption quantity. The objective was to study how food sensory imagery influences portion size selection of foods varying in energy density (brownie and applesauce) by 7- to 11-year-old children. During after-school time, 171 children were randomized into two conditions. Children in the food sensory imagery condition were asked to imagine the taste, smell, and texture of eating palatable foods, i.e., chocolate cereal, chocolate waffle, and chocolate candies. Children in the control condition performed a similar sensory imagery task for non-food-related activities. Children were then asked to choose between the recommended serving size, a 50% larger portion, and a 125% larger portion of either brownie or applesauce. One week later, they were placed in the same condition for the other food. Compared to the control condition, food sensory imagery led children to choose 7.1% less brownie but had no effect on applesauce portion selection. Exploratory findings showed that the food sensory imagery intervention was especially effective at reducing brownie portion size selection among children who were moderately hungry, who usually eat fast, and whose parents pressure them to eat. In conclusion, food sensory imagery may be a useful intervention to nudge children towards healthier portion size choices because it reduces the selected portion size of an energy-dense snack without reducing the selected portion size of a healthier snack.

OBJECTIVE: To explore parents' responses to sponsorship of children's sport by unhealthy food brands and two alternative pro-health sponsorship options. DESIGN: Between-subjects online experiment with four sponsorship conditions: (i) non-food branding (control); (ii) unhealthy food branding; (iii) healthier food branding; (iv) public health nutrition campaign branding. Participants were shown a short video and a promotional flyer for a fictional junior sports programme, with sponsor content representing their assigned brand. Afterwards, participants were asked a series of questions assessing their brand awareness, brand attitudes and preference for food sponsor branded products. SETTING: Australia. PARTICIPANTS: Australian parents (n 1331) of children aged 6-9 years. RESULTS: Compared with the control condition, unhealthy food sponsorship promoted increased awareness, branded product preferences and favourable attitudes towards unhealthy food sponsor brands. Healthier food sponsorship promoted similar effects for healthier food sponsor brands, except there was no significant increase in positive attitudes towards these brands. Sponsorship by public health nutrition campaigns promoted more negative attitudes towards unhealthy food sponsor brands and increased preference for healthier food sponsor branded products. Overall, healthier food sponsors and public health campaign sponsors were perceived to have better programme-sponsor fit and to be more appropriate sponsors of children's sport than unhealthy food sponsors. CONCLUSIONS: Restrictions on unhealthy food sponsorship of children's sport are needed to prevent unhealthy food brands from exploiting junior sport sponsorship to enhance their appeal. Sponsorship of children's sport by healthier food brands or public health nutrition campaigns could help promote healthier food choices among parents.

BACKGROUND: There is an active debate over the potential for market-based strategies to address micronutrient deficiencies in low- and middle-income countries. However, there are questions over the viability of market-based strategies, reflecting limited evidence on the value that low-income households attach to the nutritional attributes of processed foods. OBJECTIVE: The objective of this article is to investigate the willingness to pay of primary food purchasers in low-income households in rural Bangladesh for Shokti+, a nutritionally fortified yogurt produced and distributed by Grameen Danone Foods Limited. METHODS: A real choice experiment with economic incentives was conducted with 1000 rural food purchasers sampled from the distribution area of Shokti+ in rural Bangladesh. The choices of respondents revealed attribute nonattendance, favoring the fortification attribute over price. RESULTS: Results from a random parameter logit model found that respondents were willing to pay an average of 18 BDT (US$0.22) for fortification and 6 BDT (US$0.073) for brand name. The market price for Shokti+ at the time of the study was 10 BDT (US$0.12). The results from a random effects model suggest the magnitude of willingness to pay for fortification was primarily driven by the nutritional awareness of respondents but offset by household food insecurity. CONCLUSIONS: The article concludes that, while there is a viable market for fortified yogurt in rural Bangladesh, efforts to promote this product as a strategy to address micronutrient deficiency are best targeted at low-income households with some capacity to pay for low priced commercially produced foods.

Emerging evidence from functional magnetic resonance imaging (fMRI) brain activation studies associated with dietary behavior reveals significant interaction of biological and behavioral mechanisms in response to visualized food stimuli. Because food intake is influenced by neurosensory stimulation and memory cues, personalized food images may be useful in prompting appropriate affective responses to food intake, which may subsequently lead to healthier eating behaviors. The current study used a cross-sectional mixed methods approach to explore neural responses and self-perceptions of eating behavior during review of personalized food images. A sample of college students (N = 16; 9 females; M age = 21.44) used cell-phone cameras and an online dietary tracking website to collect and report three days of diet. Within 2-3 weeks of completing dietary tracking activity, participants underwent an fMRI scan while reviewing recorded personal images and text descriptions of their diet. They also responded to three questions related to memory for the food items and future eating intentions. Post-scan interviews explored how participants felt after reviewing personal food images and the possible impact that such review might have on future food choices. Whole brain analyses suggested, compared to a written dietary record, that the visualization of personal images of diet evoked greater brain activation in memory regions (e.g., superior frontal gyrus) along with mediating emotion (e.g., thalamus, putamen, anterior cingulate cortex), imagery and executive functions (e.g., inferior orbitofrontal gyrus, fusiform, and parietal lobe). This study offers preliminary support for the use of personal food images to strengthen dietary monitoring.

The current state of knowledge related to diet in Hashimoto thyroiditis (HT) is far from satisfactory, as many HT subjects experience several disorders and report reduced quality of life. There are three aims of the study: (1) to develop a qualitative dietary protocol (QDP; 'Diet4Hashi') as a simple, graphic-text tool dedicated to TH subjects, (2) to evaluate the use of the QDP in dietetic counseling compared to conventional dietetic counseling (CDC) in HT women, and (3) to assess the impact of both the QDP and the CDC on the diet quality, quality of life, adiposity, and metabolic parameters of HT women. The QDP is based on subject self-monitoring supported with a graphic-text tool to help them in food selection and adequate food frequency consumption, while the CDC on oral explanation and printed sample menus were provided by a dietician. The QDP contains two lists: (A) foods recommended for consumption and (B) foods with limited consumption, along with indicated consumption frequency per day/week/month. Both approaches include the same dietary recommendations for HT extracted from the literature but differ in subject-dietician cooperation. To summarize the evidence regarding dietary recommendations in HT, the PubMed, Embase, and Cochrane Library databases (to March 2019) and the bibliographies of key articles were searched. The study is designed as a dietary intervention lasting six months in two parallel groups: experimental and control. In the experimental group, the QDP will be applied, while in the control group, the CDC will be applied. In total, the study will include a baseline of 100 women with diagnosed HT. The subjects will be randomly allocated into the experimental/control groups (50/50). Data related to diet quality and other lifestyle factors, nutrition knowledge, quality of life, thyroid function, body composition, blood pressure, serum fasting glucose, and lipid profile at baseline and after a six-month follow-up will be collected. This study was conducted to develop a dietary protocol (Diet4Hashi) that is easy to follow for HT subjects, and it will contribute to providing valuable data that are useful to dieticians and physicians. It is anticipated that this graphic-text qualitative dietary protocol, by improving food selection and diet quality, may reduce adiposity and improve metabolic parameters and the quality of life of HT women.

Health messages may be an important predictor in the selection of healthier food choices among young adults. The primary objective of our study is to test the impact of labeling whole grain pasta with a health message descriptor displayed at the point-of-purchase (POP) on consumer choice in a campus dining setting. The study was conducted in a large US college dining venue during lunch service; data were collected during a nine-week period, for a total of 18 days of observation. Each day, an information treatment (i.e., no-message condition; vitamin message; fiber message) was alternated assigned to whole grain penne. Over the study period, the selection of four pasta options (white penne, whole grain penne, spinach fettuccine, and tortellini) were recorded and compiled for analysis. Logistic regression and pairwise comparison analyses were performed to estimate the impact of health messages on diners' decisions to choose whole grain penne among the four pasta types. Our results indicate that only the message about vitamin benefits had a significant effect on this choice, with a 7.4% higher probability of selecting this pasta than the no-message condition and 6.0% higher than the fiber message condition. These findings suggest that psychological health claims (e.g., reduction of fatigue) of whole grains seem more attractive than physiological health claims (e.g., maintaining a healthy weight) for university students. In line with the 2015-2020 Dietary Guidelines for Americans, our results suggest that small changes made at the POP have the potential to contribute to significant improvements in diet (e.g., achieving recommended levels of dietary fiber). These findings have important implications for food service practitioners in delivering information with the greatest impact on healthy food choices.

Pulses, including peas, are a good source of protein, dietary fiber, folic acid, and iron and are reported to reduce the risk for cardiovascular disease and diabetes. However, pulse ingredients present a known challenge as they exhibit a grassy/beany off-flavor. Heat treatment in some cases can decrease this off-flavor. The objective of this study was to determine the effect of substitution of 20% split yellow pea (SYP) flour treated by Revtech thermal processing at 140 °C with 10% steam (RT10%) and without steam (RT0%) for wheat flour in bread on the sensory attributes, acceptability, nutrient composition, firmness, color, and pH. RT10% was more acceptable overall than bread with untreated pea flour (USYP) or RT0% as assessed by 110 consumers. Sensory attributes were defined and measured on 15-cm line scales by an 11 member trained panel. Attributes associated with RT10% included wheaty, sweet, and yeast aromas and wheaty flavor, whereas attributes associated with USYP and RT0% were pea and nutty aroma and flavor. Although firmness and dryness were higher in RT10%, the acceptability of the bread texture was not affected. This sample contained significantly higher protein and lower carbohydrate than the wheat sample. PRACTICAL APPLICATION: Revtech (RT), a novel thermal process, when applied at 140 °C with steam to split yellow pea (SYP) flour successfully increased the acceptability of white pan bread fortified at 20% compared to bread fortified with RT 140 °C with no steam, and untreated SYP flours. This could be due to its association with wheaty aroma and flavor attributes rather than the pea aroma and flavor attributes of the other two breads.

This study aimed to assess how packaging imagery used to convey that a natural yogurt is sweetened influences consumer expectations and willingness to buy. Four packages of sweetened natural yogurt were designed, in which the message that they were sweetened was conveyed through three different images (sugar cubes, a sack of sugar and a spoon of sugar) and through only text. The results of a pretest consisting of a word association task and a main experiment consisting of an online survey show that packages in which the message that the yogurt is sweetened is conveyed by using an image together with a textual claim instead of just a textual claim are expected to be sweeter. However, some differences can be appreciated depending on the specific image that is depicted (with the package showing an image of sugar cubes raising the higher sweetness expectations). Moreover, results show that Willingness to buy is positively associated with the attributes Natural Ingredients, Healthy and Quality, and in a slightly negative way with the attribute Sweet. Overall, these results suggest that although using packaging imagery to convey a message may enhance consumer expectations and willingness to buy, its effect on consumers' attitude towards the product may ultimately depend on the subject of the image that is depicted and in the valence of the message to be conveyed. These findings are discussed in the context of packaging design and consumer research, and directions for further research are provided. This study may help packaging designers and dairy companies to better communicate the desired message to consumers and to improve the marketing performance of their products.

Young adults are the highest consumers of food prepared outside home, which has been linked to weight gain. The aim of this qualitative research was to gather opinions from young adults about what influences their food choice when eating out and if they so desired, what might enable healthy choices. Thirty-one adults aged 18 to 30 years participated in four focus groups (females = 24). Predetermined questions were used to guide discussions which were audiotaped then transcribed. The content was organized into themes and sub-themes using NVivo software. Two broad groupings arose-personal behaviors and changes to physical and social food environments. For many, eating out was viewed as a special occasion so that healthy food was not a priority and despite understanding health consequences of poor diets this was not an immediate concern. Price discounts and menu-labelling were suggested and trust in credible organizations and peers' endorsement of meals and venues expressed. The role of smartphones in the modern food environment emerged as a tool to enable immediate access to many restaurants to order food and access reviews and social media as a source of persuasive food imagery. Current menu-labelling initiatives should continue, food pricing be explored and influence of smartphones on diet further researched. However, these findings may be limited by the high proportion of women and higher socioeconomic status and urban residence of many participants.

Emerging evidence suggests a link between young people's interest in alternative food production practices and dietary quality. The primary purpose of this study was to examine the impact of a student-driven sustainable food systems education and promotion intervention on adolescent school lunch selection, consumption, and waste behaviors. Sixth grade science teachers at two middle schools (n = 268 students) implemented a standards-based curriculum on sustainable food systems, addressing the environmental impacts of food choices and food waste. The cumulating curriculum activity required the 6th grade students to share their food systems knowledge with their 7th and 8th grade counterparts (n = 426) through a cafeteria promotional campaign to discourage food waste. School-wide monthly plate waste assessments were used to evaluate changes in vegetable consumption and overall plate waste using a previously validated digital photography method. At baseline, the intervention students consumed significantly less vegetables relative to the control group (47.1% and 71.8% of vegetables selected, respectively (p = 0.006). This disparity was eliminated after the intervention with the intervention group consuming 69.4% and the control consuming 68.1% of selected vegetables (p = 0.848). At five months follow up, the intervention group wasted significantly less salad bar vegetables compared to the control group (24.2 g and 50.1 g respectively (p = 0.029). These findings suggest that food systems education can be used to promote improved dietary behaviors among adolescent youth.

Some authors have suggested that eating pleasure is underused to promote healthy eating. However, little is known about the potential of pleasure-oriented messages to lead to healthier food choices. The aim of this study was to examine the effects of pleasure- and health-oriented messages on food choices made from a buffet. One hundred and ninety-eight participants (50% women), unaware of the real objective of the study, were randomized in three groups: 1) pleasure, 2) health, and 3) control. They first completed three 24â¯h food recalls to assess their overall diet quality using the Canadian Healthy Eating Index (C-HEI; score: 0 to 100). Thereafter, participants came to the research institute and those randomized in the "pleasure" and "health" groups read a leaflet on healthy eating, using either a pleasure or a health orientation respectively. Participants in the control group had no leaflet to read. All participants had subsequently to choose four food items in a buffet offering both healthy and unhealthy foods. Results showed a group by diet quality interaction (pâ¯=â¯0.02). Among participants with lower diet quality (C-HEI score below 50), those in the pleasure and health groups were more likely than participants in the control group to choose a healthier main course (prevalence ratios (PR) 1.71, 95% CI 1.12-2.62 and 1.83, 95% CI 1.21-2.77 for the pleasure and health group respectively) and a healthier beverage (PR 1.67, 95% CI 1.02-2.71 and 1.66, 95% CI 1.02-2.72, respectively). No such effect was observed among participants with higher C-HEI scores. In conclusion, our results suggest that in people with sub-optimal dietary habits, pleasure-oriented messages and traditional health messages are both useful to favor healthy main course and beverage choices.

BACKGROUND: Most children eat fewer vegetables than recommended. Storybooks and sensory play may increase vegetable intake. OBJECTIVE: This study tested the effects on intake of learning about an unfamiliar vegetable (celeriac) through storybooks and sensory play. It was predicted that an illustrated, congruent storybook would increase intake of celeriac compared to an incongruent storybook (carrot); and that adding congruent sensory play with celeriac to the storybook would produce a synergistic effect on intake of celeriac. DESIGN: Children from 12 UK preschools were randomly assigned by clusters to four intervention conditions using a 2×2 factorial design. The factors were vegetable congruency (sensory play and/or storybook were congruent, or incongruent [carrot] with celeriac) and intervention type (storybook only or storybook combined with sensory play). PARTICIPANTS/SETTING: Three hundred and thirty-seven children aged 2 to 5 years were recruited to take part in November 2017. INTERVENTION: Over a 2-week period, children in all four conditions were read a vegetable storybook featuring celeriac or carrot. In addition, two conditions received sensory play with either carrot or celeriac added to the storybook method. MAIN OUTCOME MEASURES: Intake of the unfamiliar vegetable (celeriac) was measured at baseline and after the 2-week intervention. STATISTICAL ANALYSIS PERFORMED: Complex samples logistic regression and general linear modeling were performed to examine group differences at post-intervention. RESULTS: Children receiving the congruent (celeriac) storybook had higher odds of eating celeriac compared to children who received the incongruent (carrot) storybook. Receiving congruent sensory play increased the odds of eating celeriac, whereas receiving incongruent sensory play did not. From the 267 children who completed both baseline and post-intervention assessments, 85 ate no celeriac at baseline and were classed as non-eaters. Sensory play (congruent or incongruent) increased the odds of eating some celeriac in non-eaters compared to storybook only conditions. CONCLUSIONS: Congruency between storybook and vegetable increased intake; sensory play with celeriac increased the likelihood of eating celeriac. Storybooks and sensory play are simple interventions to increase willingness to try an unfamiliar vegetable.
