L.M. Janssen Duijghuijsen

L.M. Janssen Duijghuijsen is a Researcher at Wageningen University's Food, Health & Consumer Research department. Their work focuses on gastrointestinal health, microbiome dynamics, and nutritional interventions, particularly in conditions like lactose intolerance and irritable bowel syndrome (IBS). They completed a PhD in 2017 on protein bioavailability and gut immunity, supervised by Professors Keijer, Wichers, and van Norren.

Research interests include probiotic/prebiotic effects, dietary lipid impacts on the microbiome, and clinical trials evaluating food-based interventions. Key contributions involve studies on acacia fiber and probiotics for IBS symptoms and lactose supplementation adaptations in non-persistent lactase genotypes.

Publications span peer-reviewed journals like European Journal of Nutrition and American Journal of Clinical Nutrition, with notable work on microbiome adaptation and immune responses. Media engagements include expert commentary on lactose tolerance and dairy consumption.

Presentations include discussions on lactose supplementation effects and probiotic interventions at academic and professional conferences. The PhD project, 'Good, bad or risky? Models to study protein bio-availability and effects on gut barrier function and intestinal immunity,' received significant academic and public attention.
