Crohn’s disease (CD) is a chronic, relapsing multifactorial inflammatory condition of the gastrointestinal tract, which is diagnosed under the age of 17 in 25% of patients, categorized as pediatric CD (pCD). Exclusive enteral nutrition (EEN) is a first-line therapy for inducing remission in pCD, yet its precise mechanisms remain poorly understood. This review summarizes the complex interplay of EEN-induced protective changes i...
Controversy on health-based guidance values for bisphenol A—the need of criteria for studies that serve as a basis for risk assessmentNARA Subscribed
Since 2006, the responsible regulatory bodies have proposed five health-based guidance values (HBGV) for bisphenol A (BPA) that differ by a factor of 250,000. This range of HBGVs covers a considerable part of the range from highly toxic to relatively non-toxic substances. As such heterogeneity of regulatory opinions is a challenge not only for scientific risk assessment but also for all stakeholders, the Senate Commission on F...
Commentary of the SKLM to the EFSA opinion on risk assessment of N-nitrosamines in foodNARA Subscribed
Dietary exposure to N-nitrosamines has recently been assessed by the European Food Safety Authority (EFSA) to result in margins of exposure that are conceived to indicate concern with respect to human health risk. However, evidence from more than half a century of international research shows that N-nitroso compounds (NOC) can also be formed endogenously. In this commentary of the Senate Commission on Food Safety (SKLM) of the...
Opinion on acetaldehyde as a flavouring substance: considerations for risk assessment Acetaldehyde occurs naturally in many foods and is also used as a flavouring due to its fruity aroma. The International Agency for Research on Cancer (IARC) classified acetaldehyde as possibly carcinogenic to humans and, in combination with oral intake via alcoholic beverages, as carcinogenic to humans. Therefore, the question arises whether...
Reduced microbial diversity and high numbers of one single Escherichia coli strain in the intestine of colitic miceNARA Subscribed
Summary Commensal bacteria play a role in the aetiology of inflammatory bowel diseases (IBD). High intestinal numbers of Escherichia coli in IBD patients suggest a role of this organism in the initiation or progression of chronic gut inflammation. In addition, some E. coli genotypes are more frequently detected in IBD patients than others. We aimed to find out whether gut inflammation in an IBD mouse model is associated with a...
