"Die Warmhaltezeit zubereiteter Speisen ist zu minimieren, möglichst auf maximal 30 Minuten. Eine Warmhaltezeit von über drei Stunden ist inakzeptabel" (DGE 2009). Derartige Empfehlungen sprechen die Deutsche Gesellschaft für Ernährung (2009), der aid infodienst (2010), die Verbraucherzentrale Nord rheinWestfalen (2010) und andere Institutionen zum Warmhalten von Speisen in der Gemeinschaftsverpflegung aus. Ihre Begründung liegt in den ernährungsphysiologischen, sensorischen und gegebenenfalls sogar hygienischen Einbußen der Speisenqualität. Die Realität sieht in der Regel jedoch anders aus. Insgesamt gestattet die vorhandene Datenlage keine fundierte Beurteilung, ob das Warmhaltesystem eine Schulverpflegung von ausreichender ernährungsphysiologischer Qualität ermöglicht. Die empfohlenen Warmhaltezeiten werden in der Praxis häufig überschritten, was zumindest die sensorische Qualität, aber auch den Nährstofferhalt beeinflussen dürfte. Daher sind neue und weiterführende Untersuchungen der Speisequalität im Warmhaltesystem dringend geboten.

The Coronary Health Improvement Project (CHIP) for Lowering and Improving Psychological Health
(2011)
This study extends previous research evaluating the association between the CHIP intervention, change in body weight, and change in psychological health. A randomized controlled health intervention study lasting 4 wk. was used with 348 participants from metropolitan Rockford, Illinois; ages ranged from 24 to 81 yr. Participants were assessed at baseline, 6 wk., and 6 mo. The Beck Depression Inventory (BDI) and three selected psychosocial measures from the SF-36 Health Survey were used. Significantly greater decreases in Body Mass Index (BMI) occurred after 6 wk. and 6 mo. follow-up for the intervention group compared with the control group, with greater decreases for participants in the overweight and obese categories. Significantly greater improvements were observed in BDI scores, role-emotional and social functioning, and mental health throughout follow-up for the intervention group. The greater the decrease in BMI through 6 wk., the better the chance of improved BDI score, role-emotional score, social functioning score, and mental health score, with odds ratios of 1.3 to 1.9. Similar results occurred through 6 mo., except the mental health variable became nonsignificant. These results indicate that the CHIP intervention significantly improved psychological health for at least six months afterwards, in part through its influence on lowering BMI.
Sustainability is a central issue in food business and food retailing since approximately 3 years (See Teitscheid 2011). Various influential factors are significant for this development. On the one hand consumers choices are changing (See GFK et al. 2009). They are looking for natural, good and healthy food; they have a longing for home and an intact world (See iSuN 2010). The image of a highly efficient, but often ruthless industrial food production in regards to mankind and nature is not appropriate here. On the other hand, raw materials are scarce and, thus, very valuable. Bad harvests, mostly interpreted as a result of climate change, worldwide increasing consumption and the production of food in favor of energy production instead of nutritional aims, lead to a re-evaluation of agricultural resources and their producers. Within this context, food industry is searching for new forms of cooperation and partnership along the value chain in order to secure their resource basis. In the light of their significant environmental impact, an increasing number of companies also start to work on the environmental assessment and optimization of their products and value chains. Therefore they need employees with valid knowledge and competencies in sustainability and resources management. Based on this demand, the master's program "Sustainable Services and Nutrition Management" started in 2009 in the University of Applied Sciences in Münster (Germany)1. This text reports about how the topic of resource efficiency in food/nutrition industry has been integrated within the study program, which projects have been worked on and what experience could be gained from them.
