Goebelbecker; Patrick C. Ruff The current draft of Regulation (EC) 852/2004 promotes a food safety culture as a general principle. The various stakeholders evaluate this planned new development quite differently. While this is very welcome from a scientific point of view, there are still considerable objections from stakeholders of the area for implementation and monitoring. The challenge is how to integrate the principles into industry, and to measure and verify their effectiveness. In this article, the dimensions of food safety culture are illustrated, and an evaluation system is outlined. 2021-01-02T00:00:00Z https://fuldok.hebis.de/xmlui/handle/fuldok/844 Self-administered use of complementary and alternative medicine (CAM) supplements and antioxidants in cancer therapy and the critical role of Nrf-2 – a systematic review Birringer, Marc; Krejbich, Paula Complementary and alternative medicine (CAM) supplements are widely used by cancer patients. Dietary supplements, vitamins and minerals, herbal remedies, and antioxidants are especially popular. In a systematic literature review, 37 studies, each including more than 1000 participants, on CAM, dietary supplement, and vitamin use among cancer patients were identified. Accordingly, cancer patients use antioxidants such as vitamin C (from 2.6% (United Kingdom) to 41.6% (United States)) and vitamin E (from 2.9% (China) to 48% (United States)). Dietary supplements and vitamins are taken for different reasons, but often during conventional cancer treatment involving chemotherapy or radiotherapy and in a self-decided manner without seeking medical advice from healthcare professionals. Drug–drug interactions with dietary supplements or vitamins involving multiple signaling pathways are well described. Since most of the anticancer drugs generate reactive oxygen species (ROS), an adaptive stress response of healthy and malignant cells, mainly driven by the Nrf-2-Keap I network, can be observed. On the one hand, healthy cells should be protected from ROS-overproducing chemotherapy and radiotherapy; on the other hand, ROS production in cancer cells is a “desirable side effect” during anticancer drug treatment. We here describe the paradoxical use of antioxidants and supplements during cancer therapy, possible interactions with anticancer drugs, and the involvement of the Nrf-2 transcription factor. 2022-10-30T00:00:00Z https://fuldok.hebis.de/xmlui/handle/fuldok/835 Ulrich Ermann, Ernst Langthaler, Marianne Penkerund Markus Schermer (2018): Agro-Food Studies.

We therefore conducted a case study in a German region through semi-structured expert interviews with grocery retail store owners. From the collected responses, we applied a qualitative content analysis. The results indicated that store owners try to avoid food waste as this incurs a financial loss for them that directly affects them personally, as opposed to store managers of supermarket chains who receive a fixed salary. The main causes of food waste in the grocery retail stores in the region surveyed are expiration dates, spoilage, consumer purchasing behavior, and over-ordering of food products. The most appropriate food waste prevention strategies developed by store owners are those based on store owners’ experience and their own management style, such as the optimization of sales and management strategies, including precise planning, accurate ordering, and timely price reductions on soon-to-be-expiring food products. The redistribution of food surpluses as donations to food banks, employees, and as animal feed further helps to reduce the amount of food waste, but not the financial loss. This study enhances the literature by revealing that grocery retail store owners have the ability and are willing to successfully implement and enforce food prevention strategies in their stores. 2021-01-08T00:00:00Z
