    Traditional foodstuffs play an important role in household food security. No research has, however, attempted to examine traditional foodstuffs in light of disasters and crises. Such research can provide a useful outlook on how traditional foodstuffs can aid households in a situation of disrupted food supply. This outlook becomes relevant in view of future disastrous events that can undermine household food security, especially in poor disadvantaged communities. This study examined the role of traditional foodstuffs during a major crisis. The study adopted an ethnographic perspective and the method of semi-structured household interviews to explore how traditional foodstuffs were used by communities in the city of Mosul, Iraq, under the ISIS administration and during the liberation war (2016-2017). The study showcased the critical role of traditional foodstuffs in survival of local households. It highlighted the importance of cross-generational knowledge of traditional foodstuffs in community preparedness for disasters and crises. The study proposed to integrate traditional foodstuffs into governmental strategies on household food security in Iraq, and beyond. It suggested including traditional foodstuffs in the humanitarian food supply chains in the regions prone to disasters and crises. Future research should examine the prerequisites for such inclusion, especially from the viewpoint of societal and political acceptance of traditional foodstuffs and methods of their production.

    Low consumption of vegetables in children is a concern around the world, hence approaches aimed at increasing intake are highly relevant. Previous studies have shown that repeated taste exposure is an effective strategy to increase vegetable acceptance. However, few studies have examined the effect of repeated taste exposure on children varying in bitter taste sensitivity. This study investigated the influence of taste genotypes and phenotypes on the effects of repeated taste exposure to a Brassica vegetable. 172 preschool children aged 3-5 years were recruited into this study. Turnip was selected as the target vegetable and parents completed a questionnaire to ensure unfamiliarity. During the intervention, children were exposed to steamed-pureed turnip for 10 days (once/day). Intake and liking were measured before, during and after the intervention, and a follow-up was done 3 months post-intervention. Taste genotypes (TAS2R38 and gustin (CA6) genotypes) and taste phenotypes (PROP taster status and fungiform papillae density) were determined. There was a significant effect of exposure shown by significant increases in intake (p

    Changes in blood glucose are hypothesized to influence cognitive performance and these changes can be affected by certain nutrients. This double-blind 4-period cross-over study evaluated the effects of a slow-release modified sucrose (isomaltulose) in combination with a high concentration of lactose on cognitive performance of 5-6 year old children. Thirty children received a standard growing upmilk (Std GUM), reformulated growing up milk (Reform GUM), standard growing up milk with lactose-isomaltulose (Iso GUM), and a standard glucose drink (Glucose). The CDR System, a computerised cognitive assessment system, was used to assess various measures of attention and memory of the children at baseline (T=0), 60 (T=1), 120 (T=2), and 180 (T=3) minutes following the intake of test products. Overall, there was a decline in performance over the morning on almost every cognitive task. Children showed better attention following consumption of Iso GUM compared to Std GUM but attention was not significantly different than Reform GUM and glucose. Also, Iso GUM conferred a beneficial effect over both Reform GUM and glucose on sensitivity index of numeric working memory with no difference observed between Iso GUM and Std GUM. Surprisingly, glucose group showed lowest decline in the sensitivity index of spatial working memory and highest speed in picture recognition, although the latter was significantly better than Reform GUM only. For speed of spatial working memory, Reform GUM had the lowest decline but was significantly different only with Std GUM. There was, however, no significant difference among conditions for continuity of attention, speed of numeric working memory and picture recognition sensitivity. Despite the small sample size, the findings are intriguing as carbohydrate composition seems to influence some aspects of cognitive performance such as attention and memory. However, further studies are needed to confirm these findings.

    Three recent studies showed that taste intensity signals nutrient content. However, current data reflects only the food patterns in Western societies. No study has yet been performed in Asian culture. The Malaysian cuisine represents a mixture of Malay, Chinese and Indian foods. This study aimed to investigate the associations between taste intensity and nutrient content in commonly consumed Dutch (NL) and Malaysian (MY) foods. Perceived intensities of sweetness, sourness, bitterness, umami, saltiness and fat sensation were assessed for 469 Dutch and 423 Malaysian commonly consumed foods representing about 83% and 88% of an individual's average daily energy intake in each respective country. We used a trained Dutch (n = 15) and Malaysian panel (n = 20) with quantitative sensory Spectrum™ 100-point rating scales and reference solutions, R1 (13-point), R2 (33-point) and R3 (67-point). Dutch and Malaysian foods had relatively low mean sourness and bitterness (

    PMID: 20600418 DOI: 10.1016/j.appet.2010.06.007
    The shrimp paste called belacan is a traditional umami taste condiment extensively used in Malaysia that is rich in glutamate and 5'-nucleotides. The aim of this study was to determine the concentration of glutamate and 5'-nucleotides of various types of foods prepared with belacan and to measure their sensory attributes. The concentration of free glutamic acid found in different brands of belacan was 180-530mg/100g and in local dishes 601-4207mg/100g. The total amount of 5'-nucleotides in belacan samples ranged from 0.85 to 42.25μg/g. A Quantitative Descriptive Analysis (QDA) using a list of 17 sensory attributes showed a good correlation between belacan concentration in the final food and a range of positive sensory attributes, except for bitter, sweet, sour taste and astringency. Belacan also contains bitter, sweet and sour compounds that change the positive attributes of belacan at higher concentrations. The highest aroma attributes were linked to nasi goreng belacan (belacan fried rice) while the highest flavour attributes were found in sambal belacan. There was a 32 folds significant increase of umami attributes with the addition of belacan to final foods. The optimum amount of belacan was 0.45% for asam pedas (tamarind flavoured dish with belacan), 18% for sambal belacan (chilli belacan), 1.5-2.5% for kangkong goreng belacan (stir fried water convolous with belacan), and 2% for nasi goreng belacan.
  6. Relationship between work-family conflict and unhealthy eating: Does eating style matter?
    Shukri M, Jones F, Conner M
    Appetite, 2018 04 01;123:225-232.

    There is increasing evidence to suggest that work-family conflict is implicated in poor eating patterns. Yet, the underlying mechanism remains unexplored. The objectives of the present study were to demonstrate the interplay between work-family conflict, eating style, and unhealthy eating, and to test whether body mass index (BMI) and its interactions further explicate the relationships. In this study, 586 Malaysian adults (normal weight n = 437, overweight n = 149) completed a questionnaire, which included demographic variables, work-family scales, eating style measures, namely, restrained, emotional or external eating and reported food intake. As hypothesized, results showed that family-to-work conflict (FWC), emotional eating and external eating were positively related to unhealthy food consumption. In addition, emotional eating was found to moderate the impact of FCW on eating. These findings are consistent with research that has revealed emotional eating can indeed increase the positive association between stress such as conflict and unhealthy food choices. However, we found no clear support for the interactive effects of BMI. Our research builds on the findings of existing research as it demonstrates the role of eating style in explaining the association between work-family conflict and unhealthy eating. This conclusion has potential implications for appropriate interventions and calls for the enhancement of various policies to tackle obesity and other health problems.
  7. Relation of preconception eating behaviours to dietary pattern trajectories and gestational weight gain from preconception to late pregnancy
    Loh J, Loy SL, Appannah G, Colega MT, Godfrey KM, Yap F, et al.
    Appetite, 2024 Apr 03;198:107336.
    PMID: 38574819 DOI: 10.1016/j.appet.2024.107336
    Studies examining preconception eating behaviours with longitudinal dietary patterns from preconception to late pregnancy as well as gestational weight gain (GWG) are limited. We derived dietary pattern trajectories from preconception to late-pregnancy, and related preconception eating behaviours to these trajectories and GWG. Preconception eating behaviours were assessed using the Three-Factor Eating Questionnaire measuring cognitive restraint (CR) - conscious restriction of food intake, emotional eating (EE) - overeating in response to negative emotions, and uncontrolled eating (UE) - overeating with a feeling of lack of control. Dietary intakes were measured at preconception, 20-21 and 34-36 weeks' gestation with food frequency questionnaires. Dietary patterns were determined using factor analysis, and trajectories derived using group-based trajectory modelling. Inadequate and excessive GWG were defined according to Institute of Medicine guidelines based on weights at preconception and the last antenatal visit (median: 38 weeks' gestation). Two dietary patterns were derived: 'Fast Food, Fried Snacks and Desserts (FFD)' and 'Soup, Fish and Vegetables (SFV)'. Adherence trajectories from preconception to late-pregnancy were characterised as consistently high ("stable-high") and low ("stable-low"). Women with higher UE scores had higher odds of being in the "stable-high" trajectory (n = 34) of the FFD pattern [Odds Ratio (OR): 1.25, 95% Confidence Interval (CI): 1.03, 1.51], compared to "stable-low" (n = 260). Percentages of women with inadequate, adequate or excessive GWG were 21.7% (n = 70), 25.8% (n = 83), and 52.5% (n = 169), respectively; women with higher EE scores had a higher likelihood of excessive GWG [Relative Risk Ratio (RRR): 1.35, 95% CI: 1.02, 1.80], but this association was attenuated after adjusting for preconception body mass index. Eating behaviour interventions to improve dietary patterns among pregnant women may need to start as early as preconception, incorporating strategies to manage UE.
  8. Psychological distress as a mediator in the relationships between biopsychosocial factors and disordered eating among Malaysian university students

    PMID: 22885453 DOI: 10.1016/j.appet.2012.08.002
    The mechanism linking biopsychosocial factors to disordered eating among university students is not well understood especially among Malaysians. This study aimed to examine the mediating role of psychological distress in the relationships between biopsychosocial factors and disordered eating among Malaysian university students. A self-administered questionnaire measured self-esteem, body image, social pressures to be thin, weight-related teasing, psychological distress, and disordered eating in 584 university students (59.4% females and 40.6% males). Body weight and height were measured. Structural equation modeling analysis revealed that the partial mediation model provided good fit to the data. Specifically, the relationships between self-esteem and weight-related teasing with disordered eating were mediated by psychological distress. In contrast, only direct relationships between body weight status, body image, and social pressures to be thin with disordered eating were found and were not mediated by psychological distress. Furthermore, multigroup analyses indicated that the model was equivalent for both genders but not for ethnic groups. There was a negative relationship between body weight status and psychological distress for Chinese students, whereas this was not the case among Malay students. Intervention and prevention programs on psychological distress may be beneficial in reducing disordered eating among Malaysian university students.

    Appetite, 2018 06 01;125:90-97.
    PMID: 29408380 DOI: 10.1016/j.appet.2018.01.037
    BACKGROUND AND AIMS: Given the increasing prevalence of childhood obesity in Malaysia, examination of family environmental factors is warranted. Reviews from developed countries report inconsistent findings on the relationship between parental-child feeding practices and child weight-related health outcomes. The current study aimed to examine parent-child feeding practices by familial-child characteristics in Malaysia.

    MATERIALS AND METHOD: The Family Diet Study was conducted with urban Malay families and included a child aged 8-12 years and their main carer(s). Seven domains of parent-child feeding practices were assessed using the child feeding questionnaire and familial demographics, including socio-economic status, child anthropometry and dietary intake were collected. Inferential statistics were used to explore the relationships between variables.

    RESULTS: Of the 315 families enrolled, 236 completed all measures, with the majority of parent-reporters being mothers (n = 182). One-third of the children were classified as overweight/obese. Three domains of parent-child feeding practices had median scores of 4.0 out of 5.0 [concern about child overweight (CCO) (Interquartile range (IQR): 3.3, 4.7); pressure-to-eat (PTE) (IQR: 3.3, 4.5) and food monitoring (IQR: 3.0, 5.0)]. The domain of 'perceived child overweight' was positively associated with child age (r = 0.45, p

    PMID: 23017466 DOI: 10.1016/j.appet.2012.09.011
    The aim of this study was to assess nutritional supplement use among fitness club participants in Tehran, Iran. A cross sectional study was conducted in 24 fitness clubs throughout the city of Tehran, Iran. A total of 1625 fitness club participants were recruited to participate in this study. They were asked to complete a self-administered pre-tested questionnaire. Descriptive statistics and chi-square test were performed to determine the characteristics of participants, reasons for supplement use, sources of information and also the influential advisors regarding nutritional supplement use. A high prevalence rate of nutritional supplement use (66.7%) was reported. Overall, multivitamin-mineral (43.8%) and iron tablets (30.5%) were the common nutritional supplements used and only a small number of participants used illegal substances (0.5%). Younger participants were more likely to use ergogenic aids, whereas, older participants were more likely to use vitamin D. Males were more likely than females to use creatine and amino acids, whereas, iron tablets and mint water were more common among females. Also, males were more likely to use nutritional supplements for increasing energy, whereas, females were more likely to use nutritional supplements for nutritional deficiencies. In conclusion, a high prevalence rate of nutritional supplement use was seen among participants.
  11. No effect of monosodium glutamate on subjective appetite and subsequent energy intake in children of different ethnicities

    Studies have shown that monosodium glutamate (MSG) can enhance satiety and reduce appetite among infants and adults. In a multi-ethnic country such as Malaysia, it is also important to consider whether ethnic variations will influence the effects of MSG on appetite regulation. Thus, this crossover study aimed to investigate the effects of MSG on the subjective appetite and subsequent energy intake among Malaysian children from the three major ethnic groups, namely the Malays, Chinese and Indians. A total of 92 participants aged 9-11 years from the three ethnic groups were recruited for this study. A cup of low-energy vegetable preload soup (100g, with MSG or without MSG) was served to each of the participants on the day of the study, followed by an ad libitum meal 45 min later. Appetite ratings of hunger, fullness, desire to eat and desire to snack were recorded using visual analogue scale (VAS) before the preload, after the preload, before the ad libitum meal and after the ad libitum meal. Results showed that the subjective appetite of the children did not differ between preload conditions (MSG+ or MSG-) throughout the study. Malay, Chinese and Indian children had similar total energy intake during the subsequent meal after the consumption of preload soups. In conclusion, the addition of MSG to low energy preload neither influenced the perception of appetite nor total energy intake in a subsequent ad libitum meal among children. No difference attributable to the participants' ethnicity was observed. Future studies should be conducted to examine whether repeated ingestion of MSG-containing protein-rich preload has potential longer-term effects on appetite and subsequent meal intakes among children from different ethnicities.

  12. Menu labeling influence on purchase behaviors: Applying the theory of planned behavior and health consciousness
    Rahamat S, Jeong E, Arendt SW, Xu Y
    Appetite, 2022 Feb 11.
    PMID: 35157999 DOI: 10.1016/j.appet.2022.105967
    Mixed findings have been reported in the literature on the effectiveness of menu labeling in assisting consumers to make informed purchase decisions when eating out. Therefore, this study examined factors that influenced consumers' intentions to use menu labeling and whether these intentions influenced caloric purchases relative to actual caloric needs. While other researchers have assessed impacts of menu labeling on total calories purchased, our study assessed the impact relative to caloric needs, therein recognizing that each consumer has different caloric needs. An extended theory of planned behavior (TPB) incorporating health consciousness served as the theoretical underpinning. The TPB addresses reasons why an individual takes action on a certain behavior; in the case of this research, that behavior was purchasing food. Food purchases were further operationalized using the calorie content of foods and comparing that number of calories to caloric needs. Two-step structural equation modeling was used to analyze 316 surveys from restaurant consumers. Results indicated that attitudes, subjective norms, and health consciousness positively influenced intentions to use menu labeling. Intentions to use menu labeling also significantly influenced actual purchase behaviors (measured as the difference between caloric purchases and caloric needs). Overall, the current research findings provide novel insights for researchers to further explore the role of menu labeling on purchase behavior by using the TPB model with integration of health consciousness.
  13. Knowledge, attitudes and practices of schoolchildren toward whole grains and nutritional outcomes in Malaysia

    Whole grains play an important role in regulating body weight. However, interventions aimed to increase whole grains consumption have had limited impact on body mass index for age z-score (BAZ) due to insufficient understanding of knowledge, attitudes and practices (KAP) toward whole grains. This survey aimed to evaluate whole grains KAP among schoolchildren, as well as to investigate the associations of whole grains KAP with BAZ among the schoolchildren in Negeri Sembilan, Malaysia. This cross-sectional survey was conducted among 380 schoolchildren aged 9-11 years, cluster sampled from six randomly selected schools. Data were collected through a validated self-administered guided questionnaire. Body weight and height were measured. A majority of the schoolchildren had normal body weight (56.6%), moderate whole grains knowledge (42.6%), as well as neutral attitudes (66.1%) and poor practices (58.9%) toward whole grains consumption. Significant positive associations were found between knowledge and attitudes (r = 0.337; p 
  14. Is thin in everywhere?: A cross-cultural comparison of a subsection of Tripartite Influence Model in Australia and Malaysia

    PMID: 30586595 DOI: 10.1016/j.appet.2018.12.025
    Despite growing research investigating prevalence rates of BD among Malaysian women, there has been limited research conducted in Malaysia with respect to factors contributing to its development and consequences. This study tested a subsection of the Tripartite Influence Model, investigating whether sociocultural influences (family, peers, media) lead to thin ideal internalization, which in turn lead to body dissatisfaction (BD) and subsequently restrained eating and bulimic behaviours in both Australian and Malaysian women. Participants were 421 Australian and 399 Malaysian female emerging adults aged between 18 and 25 years, (M = 20.76; SD = 2.86) who completed questionnaires assessing sociocultural influences, thin ideal internalization, body dissatisfaction, restrained eating and bulimic behaviours. The model, largely supported in both cultures, had two points of difference. For Malaysian but not Australian women, family influence was significantly linked with internalization of the thin ideal. Although BD was significantly linked with restrained eating as predicted for Australian women (albeit rather weakly), it was not significantly linked with restrained eating for Malaysian women. The striking similarity of results across both cultures, suggests that Western body ideals, with their corresponding negative sequelae, have infiltrated the collectivist and developing nation of Malaysia.
  15. Fulltext Implicit satiety goals and food-related expectations predict portion size in older adults: Findings from the BAMMBE cohort
    Pink AE, Lee LL, Low DY, Yang Y, Fong LZ, Kang AYH, et al.
    Appetite, 2023 Jan 01;180:106361.
    PMID: 36332849 DOI: 10.1016/j.appet.2022.106361
    Portion size selection is an indicator of appetite and within younger adults, is predicted by factors such as expected satiety, liking and motivations to achieve an ideal sensation of fullness (i.e., implicit satiety goals). Currently, there is limited research available on the determinants of portion size selection within older adults. Therefore, the current study aimed to examine the relationship between individual differences in implicit satiety goals, food-related expectations, and portion size selection in older adults. Free-living older adult Singaporeans (N = 115; Nmales = 62; age: M = 66.21 years, SD = 4.78, range = 60-83 years) participated as part of the Brain, Ageing, Microbiome, Muscle, Bone, and Exercise Study (BAMMBE). Participants completed questionnaires on their subjective requirements for experiencing different states of satiety and food-related expectations (i.e., liking, how filling) as well as a computerised portion size selection task. Using a multiple regression, we found that goals to feel comfortably full (B = 3.08, SE = 1.04, t = 2.96, p = .004) and to stop hunger (B = -2.25, SE = 0.82, t = -2.75, p = .007) significantly predicted larger portion size selection (R2 = 0.24, F(4,87) = 6.74, p

    Food waste has adverse economic, social, and environmental impacts and increases the prevalence of food insecurity. Panic buying at the beginning of the COVID-19 outbreak raised serious concerns about a potential rise in food waste levels and higher pressure on waste management systems. This article aims to investigate the impact of COVID-19 on food waste behaviour and the extent to which it occurs using the systematic review method. A total of 38 articles were identified and reviewed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The findings showed that the COVID-19 pandemic led to reductions in household food waste in most countries. Several changes in shopping and cooking behaviours, food consumption, and managing inventory and leftovers have occurred due to COVID-19. Based on these insights, we predicted that some desirable food-management habits would be retained, and others would roll back in the post-COVID-19 world. The review contributes to the food waste literature by offering a comprehensive overview of behavioural changes during the COVID-19 pandemic and future research directions.
  17. Greek adaptation of the Teruel Orthorexia Scale (TOS) in adults from the Republic of Cyprus: A bidimensional model may not be universal

    PMID: 38145878 DOI: 10.1016/j.appet.2023.107180
    The Teruel Orthorexia Scale (TOS) is a 17-item instrument designed to assess distinct facets of Orthorexia Nervosa (ON) and Healthy Orthorexia (HO). While a bidimensional model of TOS scores has been supported in diverse national and linguistic groups, the psychometric properties of the TOS have not been previously assessed in Greek-speaking populations. To rectify this, we assessed the psychometric properties of a novel Greek translation of the TOS in a sample of adults from Cyprus. A total of 1248 respondents (710 women, 538 men) completed the Greek TOS, as well as previously validated measures of perfectionism, obsessive-compulsive symptomatology, eating restriction, negative affect, and appearance evaluation. Our results showed that a bidimensional model of the TOS had less-than-adequate fit when modelled using both confirmatory factor analysis and exploratory structural equation modeling (ESEM). Conversely, both exploratory factor analysis and ESEM supported extraction of a 3-factor model consisting of a HO facet and separate components of emotional orthorexia and cognitive-social orthorexia. This 3-factor model showed a lack of measurement bias (measurement invariance across gender identity and lack of differential item functioning as function of age and body mass index), but there were differences in latent factor means as function of respondent age and body mass index. The 3-factor model showed adequate evidence of construct validity, with the latent emotional orthorexia and cognitive-social orthorexia facets showing significant and moderate associations with the additional constructs measured in the survey. Broadly speaking, these findings support the psychometric properties of a 3-factor model of the Greek TOS, but also suggest that the bidimensional model of the TOS may not have universal applicability. We encourage further assessments of factorial validity in other national and linguistic contexts.
  18. Glutamate. Its applications in food and contribution to health
    Jinap S, Hajeb P
    Appetite, 2010 Aug;55(1):1-10.
    PMID: 20470841 DOI: 10.1016/j.appet.2010.05.002
    This article reviews application of glutamate in food and its benefits and role as one of the common food ingredients used. Monosodium glutamate is one of the most abundant naturally occurring amino acids which frequently added as a flavor enhancer. It produced a unique taste that cannot be provided by other basic taste (saltiness, sourness, sweetness and bitterness), referred to as a fifth taste (umami). Glutamate serves some functions in the body as well, serving as an energy source for certain tissues and as a substrate for glutathione synthesis. Glutamate has the potential to enhance food intake in older individuals and dietary free glutamate evoked a visceral sensation from the stomach, intestine and portal vein. Small quantities of glutamate used in combination with a reduced amount of table salt during food preparation allow for far less salt to be used during and after cooking. Because glutamate is one of the most intensely studied food ingredients in the food supply and has been found safe, the Joint Expert Committee on Food Additives of the United Nations Food and Agriculture Organization and World Health Organization placed it in the safest category for food additives. Despite a widespread belief that glutamate can elicit asthma, migraine headache and Chinese Restaurant Syndrome (CRS), there are no consistent clinical data to support this claim. In addition, findings from the literature indicate that there is no consistent evidence to suggest that individuals may be uniquely sensitive to glutamate.

  19. Fulltext Food, culture, and identity in multicultural societies: Insights from Singapore
    Reddy G, van Dam RM
    Appetite, 2020 06 01;149:104633.
    PMID: 32084519 DOI: 10.1016/j.appet.2020.104633
    The choice of food practices can be influenced by one's identity in many societies, but has mostly been evaluated in light of the maintenance of cultural identity in migrant populations. This study focused on understanding the influence of identity on food practices among individuals in multicultural societies. We conducted 18 focus group discussions (n = 130) among Indian, Chinese and Malay women in Singapore. Focus group transcripts were analysed using Thematic Analysis both inductively and deductively. Deductive analysis was framed within a Social Representations Approach, a social psychological theory that allows a deeper understanding of the contextual aspects of identity. Participants highlighted the central position of food in social events, cultural celebrations, and persistent traditional beliefs about health (such as 'hot-cold balance'). These beliefs extended to the perception of certain traditional foods possessing medicinal properties. Importantly, the consumption of these traditional foods was accepted as necessary for the maintenance of health by the women. We propose that while cultural food practices are integral to identity preservation and identity continuity for Singaporean women from all three racial groups, this is different to other multicultural societies such as Canada where communities preserve their cultural food practices, in part, due to fear of cultural identity loss. In addition, cross-cultural food practices are readily adopted in participants' daily lives for a number of reasons such as the promotion of health, convenience, and variety. At times, this adoption blurred boundaries between different cultural cuisines. Food practices in multicultural societies like Singapore are thus a reflection of everyday multiculturalism, multicultural social policies, and attitudes towards traditional healthful food practices, and these aspects need to be considered in the development of public health policies and interventions.

    Activities that engage young children with the sensory properties of foods are popular with nursery schools, despite the lack of evidence for their efficacy in increasing children's consumption of healthy foods. This study provides the first empirical exploration of the effectiveness of a non-taste sensory activity program in a nursery school setting. Ninety-two children aged between 12 and 36 months were allocated either to an intervention group, who took part in looking, listening, feeling and smelling activities with unusual fruits and vegetables every day for 4 weeks, or to a non-intervention control group. In a subsequent mealtime taste test, children touched and tasted more of the vegetables to which they had been familiarized in their playtime activities than of a matched set of non-exposed foods. The results demonstrate that hands-on activities with unfamiliar fruits and vegetables can enhance children's willingness to taste these foods, and confirm the potential for such activities to support healthy eating initiatives.
