Individual differences in texture preferences among European children: Development and validation of the Child Food Texture Preference Questionnaire (CFTPQ)

Texture has an important role in children's acceptance and rejection of food. However, little is known about individual differences in texture preference. The aim of this study was to develop and validate a child-friendly tool to explore individual differences in texture preferences in school-aged children from six European countries (Austria, Finland, Italy, Spain, Sweden and United Kingdom). Six hundred and ten children aged 9-12 years and their parents participated in a cross-sectional study. Children completed the Child Food Texture Preference Questionnaire (CFTPQ) and a Food Neophobia Scale (FNS). The CFTPQ consisted in asking children to choose the preferred item within 17 pairs of pictures of food varying in texture (hard vs. soft or smooth vs. lumpy). Children also evaluated all food items for familiarity. Parents completed the CFTPQ regarding their preferred items, a food frequency questionnaire for their child, and provided background information. For a subset of children, a re-test was done for the CFTPQ and FNS to assess reliability. The results showed that the tool was child-friendly, had high test-retest reliability, and identified country-related differences as well as segments of children with different texture preferences (hard- vs. soft-likers). These segments differed in consumption frequency of healthy foods, and in food neophobia

Learning to Eat Vegetables in Early Life: The Role of Timing, Age and Individual Eating Traits

Vegetable intake is generally low among children, who appear to be especially fussy during the pre-school years. Repeated exposure is known to enhance intake of a novel vegetable in early life but individual differences in response to familiarisation have emerged from recent studies. In order to understand the factors which predict different responses to repeated exposure, data from the same experiment conducted in three groups of children from three countries (n = 332) aged 4–38 m (18.9±9.9 m) were combined and modelled. During the intervention period each child was given between 5 and 10 exposures to a novel vegetable (artichoke puree) in one of three versions (basic, sweet or added energy). Intake of basic artichoke puree was measured both before and after the exposure period. Overall, younger children consumed more artichoke than older children. Four distinct patterns of eating behaviour during the exposure period were defined. Most children were “learners” (40%) who increased intake over time. 21% consumed more than 75% of what was offered each time and were labelled “plate-clearers”. 16% were considered “non-eaters” eating less than 10 g by the 5th exposure and the remainder were classified as “others” (23%) since their pattern was highly variable. Age was a significant predictor of eating pattern, with older pre-school children more likely to be non-eaters. Plate-clearers had higher enjoyment of food and lower satiety responsiveness than non-eaters who scored highest on food fussiness. Children in the added energy condition showed the smallest change in intake over time, compared to those in the basic or sweetened artichoke condition. Clearly whilst repeated exposure familiarises children with a novel food, alternative strategies that focus on encouraging initial tastes of the target food might be needed for the fussier and older pre-school children

Increasing vegetable intakes: rationale and systematic review of published interventions

Purpose While the health benefits of a high fruit and vegetable consumption are well known and considerable work has attempted to improve intakes, increasing evidence also recognises a distinction between fruit and vegetables, both in their impacts on health and in consumption patterns. Increasing work suggests health benefits from a high consumption specifically of vegetables, yet intakes remain low, and barriers to increasing intakes are prevalent making intervention difficult. A systematic review was undertaken to identify from the published literature all studies reporting an intervention to increase intakes of vegetables as a distinct food group. Methods Databases—PubMed, PsychInfo and Medline—were searched over all years of records until April 2015 using pre-specified terms. Results Our searches identified 77 studies, detailing 140 interventions, of which 133 (81 %) interventions were conducted in children. Interventions aimed to use or change hedonic factors, such as taste, liking and familiarity (n = 72), use or change environmental factors (n = 39), use or change cognitive factors (n = 19), or a combination of strategies (n = 10). Increased vegetable acceptance, selection and/or consumption were reported to some degree in 116 (83 %) interventions, but the majority of effects seem small and inconsistent. Conclusions Greater percent success is currently found from environmental, educational and multi-component interventions, but publication bias is likely, and long-term effects and cost-effectiveness are rarely considered. A focus on long-term benefits and sustained behaviour change is required. Certain population groups are also noticeably absent from the current list of tried interventions

Coping with Time Pressure and Stress: Consequences for Families’ Food Consumption

This study explores the coping strategies that families apply when under time pressure and stress (time stress), and how such strategies affect food consumption at dinnertime. The data were based on photo interviewing methodology with a sample of 12 Norwegian children (ages seven and eight) and their parents. In this case, the children were asked to take photographs during their dinners at home and while shopping for groceries with their parents. The findings show that the most dominant explanation for time stress was the children’s participation in sport activities. In this regard, the families applied several coping strategies, such as skipping dinner and eating snacks instead, consuming convenience food, avoiding preference conflicts, planning for healthy dinners, involving children and grandparents in food preparation, and practising compensatory health beliefs and behaviours. This might be the first study that identifies parents’ use of compensatory health beliefs to justify children’s diets. More specifically, the parents stated that the children’s high activity levels could compensate for unhealthy food consumption. The strategies that were applied had varying influences on the families’ food consumption, depending on the parents’ confidence in cooking and meal-planning skills. It was found that parents with high confidence and skills were more likely to make healthy cooking a priority. Consequently, they served more healthy dishes at dinnertime, compared with other parents. Unlike previous studies, the findings indicate that children’s active lifestyles might not be directly related to healthy diets

Vacuolar degeneration affecting brain macrophages/microglia in variant CJD: a report on two cases

We present the neuropathology of two cases of variant Creutzfeldt-Jakob disease (vCJD) showing significant vacuolar degenerative alterations specifically affecting brain macrophages/microglia within the thalamus and, to a lesser extent, within the neocortical grey matter. Vacuolar degeneration in these cells was extensive, and likely to be associated with the development of a uniform sub-type of ‘spongiform’ vacuole seen in vCJD. The extensive morphological alterations described here closely resemble those very recently reported by Zucconi and colleagues, in response to experimental copper deficiency induced through dietary restriction, but could not be detected in cases of sporadic CJD examined. The significance of these novel findings are discussed in relation to copper homeostasis, loss of function of cellular prion protein and aberrant lysosomal catabolism within brain macrophages/microglia. This type of vacuolation may constitute a component of the overall profile of spongiform changes associated with vCJD
