Official title: A Nutritional Intervention to Prevent Stress Induced Intestinal Hyper-Permeability

Status Recruiting

Clinical Trial Summary

The interaction between the gut microbiome, the intestinal barrier, and the host plays an important role in human health. The integrity of the intestinal barrier is essential to protect against translocation of food antigens and immunostimulatory microbial metabolites from the gut lumen. Accumulating studies show that stress may negatively affect the intestinal barrier function. In a previous study, the investigators developed the Leuven Prolonged Acute Stress Test (L-PAST), which combines physical (cold water), mental (arithmetic), and social (negative feedback) aspects of stress for a prolonged (2h) time. In the current study the investigators would like, as a first aim, to investigate whether the L-PAST 1) increases intestinal permeability compared to baseline intestinal permeability, and 2) whether a nutritional intervention can improve baseline intestinal permeability as well as intestinal permeability after exposure to the L-PAST in both healthy females and men. As a second aim of the present study, the investigators would like to investigate whether prebiotics and/or L-tryptophan can attenuate the cortisol response to stress. Lastly, as acute psychosocial stress impairs cognitive functions, the investigators would like as a third aim to investigate whether prebiotics and/or L-tryptophan supplementation may prevent these impairments.
