Selected AbstractsThe importance of exposure for healthy eating in childhood: a reviewJOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 4 2007L. Cooke Abstract Children's food preferences are strongly associated with their consumption patterns. Identifying the factors that influence preferences is therefore crucial to the development of effective interventions to improve children's diets. Perhaps the most important determinant of a child's liking for a particular food is the extent to which it is familiar. Put simply, children like what they know and they eat what they like. From the very earliest age, children's experiences with food influence both preferences and intake, and research suggests that the earlier and broader that experience, the healthier the child's diet. Laboratory studies of children's food acceptance have indicated that repeated opportunities to taste unfamiliar foods results in increased liking and consumption. In order to investigate whether these results can be replicated in real-world situations, a series of naturalistic studies testing the efficacy of exposure-based interventions have been carried out. In a school-based study large increases in liking and intake of raw red pepper were seen in 5- to 7-year olds and two further studies, in which mothers used exposure techniques to increase children's acceptance of vegetables, achieved similar results. If future large-scale interventions prove to be successful, training could be offered to health professionals or directly to parents themselves. [source] MOTIVATIONS FOR PRODUCT CONSUMPTION: APPLICATION OF A PROBABILISTIC MODEL TO ADOLESCENT SMOKINGJOURNAL OF SENSORY STUDIES, Issue 2 2004DANIEL M. ENNIS ABSTRACT This paper describes a method that can be used to investigate consumers' reported reasons for using a particular product. This method is applied to ratings of degree of agreement with statements about reasons for product use. The method is illustrated using data on self-reported reasons for smoking among adolescents. The approach used is based on a probabilistic model of similarity (Ennis et al. 1988) and provides a display of the density of respondents' individual motivations concurrent with their perceptions of the statements. Factor analysis and its derived factor scores provide complementary information which is used to understand the interdependence of smoking motivations with the age of respondents and their degree of smoking. The probabilistic similarity model has many applications in studying consumer motivations such as those involved in the consumption of particular food and personal care products. [source] Whole Foods: Revitalization through Everyday Synesthetic ExperienceANTHROPOLOGY & HUMANISM, Issue 2 2000David Sutton This article explores the role of food and eating as part of migrant responses to displacement and strategies for reconstituting community and re-creating cultural continuity. Drawing on Fernandez's concept of "the return to the whole," this paper considers the nature of the cultural revitalization achieved through food events, through particular food sent "from home." Attention is paid to processes of invocation, structural repetition, and synesthesia, concepts developed by Fernandez in his work on religious revitalization movements. [source] Increased intakes of selenium-enriched foods may benefit human healthJOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, Issue 9 2007John Weldon Finley Abstract Selenium is an essential nutrient and deficient intakes compromise health in domestic animals and humans. A recommended dietary allowance (RDA) of 55 µg d,1 has been set for adult males and females in the United States; most North Americans consume more than this amount, but many residents of Europe, Asia and Africa consume less. While there are very few reports of outright Se deficiency in people consuming mixed Western diets that have Se intakes below the RDA, there is evidence that dietary intakes of selenium greater than the requirement may help reduce the risk of cancer, especially prostate cancer, to men. Selenium metabolism depends on the chemical form of Se in the diet, and some forms are better for some actions (e.g., cancer reduction) than other forms. Foods may contain different amounts and chemical forms of Se; consequently the benefits of Se may depend on the particular foods consumed. There are many reports of the chemistry and health benefits of Se from plant foods; animal foods also contain Se, but there are fewer reported studies. Fully understanding the health benefits of Se that may be gained by consumption of Se-enriched foods will require multidisciplinary approaches by teams of medical researchers, chemists, nutritionists, and agricultural scientists.

Bohle Summary Background IgE antibodies specific for the major birch-pollen allergen, Bet v 1, cross-react with homologous allergens in particular foods, e.g. apples, carrots and hazelnuts. In a high number of tree pollen-allergic individuals, this cross-reactivity causes clinical symptoms, commonly known as the ,birch-fruit-syndrome'. Objective To characterize the T cell response to the Bet v 1-related major allergen in hazelnuts, Cor a 1.04, and its cellular cross-reactivity with Bet v 1 and the homologous hazel pollen allergen, Cor a 1. Methods Using recombinant Cor a 1.04, T cell lines (TCL) and T cell clones (TCC) were established from peripheral blood mononuclear cells of tree pollen-allergic patients with associated food allergy. T cell epitopes were determined using overlapping synthetic peptides in Cor a 1.04-reactive TCL and TCC. In parallel, reactivity to Bet v 1 and Cor a 1 was tested. Results In total, 20 distinct T cell epitopes on the hazelnut allergen were identified. Several Cor a 1.04-specific TCL and TCC reacted with pollen allergens albeit less pronounced than with the hazelnut allergen. Several Cor a 1.04-specific TCC did not react with pollen allergens. Interestingly, these clones were found to react with the Bet v 1-related major allergen in carrots, Dau c 1. The cellular cross-reactivity between both food allergens could be associated with the most frequently recognized T cell epitope of Cor a 1.04, Cor a 1.04142,153. Conclusions The major hazelnut allergen cross-reacts with the major allergens of birch and hazel pollen but apparently contains a relevant T cell epitope not shared with pollen allergens. Our finding may have important implications for the specific immunotherapy of tree pollen-allergic patients suffering from concomitant hazelnut allergy. [source] | |||||||||||||
