Food Additives and Contaminants - Part A Chemistry, Analysis, Control, Exposure and Risk Assessment | Year: 2012

The aim of this work was to analyse the furan concentrations in coffee products targeted to adolescents and to estimate the health risk for those consumers by using the consumption data of the Dortmund Nutritional and Anthropometric Longitudinally Designed Study (DONALD). Three different kinds of coffee beverages were analysed: 'coffee ready to drink' (i.e. industrially manufactured and packaged products available in cans or plastic cups), 'coffee instant' (i.e. soluble coffee in powder form) and 'coffee from coffee chains' (i.e. freshly prepared coffee sampled on-site). Furan was analysed according to the US Food and Drug Administration (USFDA) method using headspace-GC-MS and quantification with standard addition. The lowest furan concentrations were found within the category 'coffee instant', with an average of 4.6 μ-1, followed by the category 'coffee ready to drink', with an average of 41.3 μgkg-1, while the products from the coffee chains showed the highest concentrations, on average 100.5 μgkg-1. According to the obtained furan contents, it seems that the highest furan exposure for adolescents is generally given in the consumption of products within the category 'coffee from coffee chains', while the lowest is given in the category 'coffee instant'. Risk assessment based on the margin of exposure (MOE) approach showed that in different consumption scenarios except for consumers of instant coffee, the MOE lay below 10,000, a range that is judged to be of public health relevance. The lowest MOE was found for consumers in the age group 10-12 years (especially females) and for both sexes in the age group 16-18 years. © 2012 Taylor & Francis.

Furan is a possible human carcinogen regularly occurring in commercially jarred complementary foods. This paper will provide a detailed exposure assessment for babies consuming these foods considering different intake scenarios. The occurrence data on furan in complementary foods were based on our own headspace-gas chromatography/mass spectrometry (HS-GC/MS) analytical results (n=286). The average furan content in meals and menus was between 20 and 30μgkg-1, which is in excellent agreement with results from other European countries. Using measured food consumption data from the Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study, the average exposures for consumers of commercially jarred foods ranged between 182 and 688ngkg-1 bwday-1, with a worst case scenario for P95 consumers ranging between 351 and 1066ngkg-1 bwday-1. The exposure data were then used to characterize risk using the margin of exposure method based on a benchmark dose lower confidence limit for a 10% response (BMDL10) of 1.28mgkg-1 bwday-1 for hepatocellular tumours in rats. The margin of exposures (MOEs) were below the threshold of 10000, which is often used to define public health risks, in all scenarios, ranging between 7022 and 1861 for average consumers and between 3642 and 1200 for the P95 consumers. Mitigative measures to avoid furan in complementary foods should be of high priority for risk management. © 2010 Blackwell Publishing Ltd.

Benzene was previously detected as a heat-induced contaminant in infant carrot juices. This study shows that carrot juice contains substances such as β-carotene, phenylalanine or terpenes that may act as precursors for benzene formation during food processing. As benzene exposure has been associated with childhood leukaemia and other cancers, this study aimed to provide a quantitative risk assessment. To accomplish this, we used measured food consumption data from the Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study, along with survey data on benzene in different juice categories. The calculated exposures for infants between 3 and 12 months were low, with averages between 1 and 10 ng/kg bw/day, resulting in a margin of exposure above 100,000. The exposures were judged as unlikely to pose a health risk for infants. Nevertheless, carcinogenic contaminants should be reduced to levels as low as reasonably achievable. The focus should be set on improving the sterilization conditions. © 2009 Elsevier Ltd. All rights reserved.

Background: The nutrition of children is also characterized by the cultural background. Till now, current recommendations do not consider this. Methods: 10 qualitative guideline-based interviews from German (n = 5) and Turkish (n = 5) mothers were conducted for this analysis, dealing with attitudes and behaviour towards nutrition and health of infants. The interviews were analysed by qualitative textual analysis. Results: The implementation of existing recommendations (e.g. breastfeeding, complementary food) in everyday life did not work as desired by Turkish as well as German mothers. Therefore, mothers were in a state of inner conflict and stress situation. That was expressed in subjective justifications of behaviour. Further more, standard terms of infant nutrition were understood differently by German and Turkish mothers. Therefore, the findings suggest that German recommendations for infant nutrition are interpreted differently from Turkish mothers. Conclusion: In advice, it can be useful to consult language or cultural mediator or choose simple words, so that language skill of parents doesn't decide on the quality. © 2014 Springer-Verlag Berlin Heidelberg.

There is still little evidence for effective interventions that prevent childhood overweight. A number of behavioral interventions have been implemented, but in order to achieve sustainable preventive effects, they should be combined with environmental interventions which target the obesogenic environment. A modifiable obesogenic factor is beverage consumption and targeting this behavior seems promising to prevent overweight in children. The behavioral and environmental approaches were combined in the "trinkfit" study, and effectiveness and feasibility were tested in a controlled intervention study. In order to prevent overweight, the intervention focused on increased water consumption of children in elementary schools. The intervention consisted of lessons on water given by the teachers (behavioral intervention) and the provision of water fountains and water bottles (environmental intervention). After one school year, the intervention had been effective in decreasing the risk of overweight in the children of the intervention group. However, this preventive effect was not observed among children with an immigrant background. Process evaluation results indicate that the combined intervention focusing on increased water consumption was sustainable and feasible in the school setting. © 2011 Springer Medizin Verlag.
