Torsten BOHN, PhD


Torsten Bohn is a nutritionist and food chemist by training. He works in close collaboration with internal partners (e.g. CIEC) and external collaborators (e.g. networks such as EU-COST actions) and strives to study especially the relation of micronutrient/secondary plant compound (including fiber) intake, their digestion and bioavailability, to markers of health and disease such as inflammation and oxidative stress, also looking for novel biomarkers (e.g. via proteomics, genomics).  Toward this end, Torsten Bohn is involved in conducting and evaluating both human observational studies such as the ORISCAV-LUX studies, and dietary intervention trials. An additional aspect is the interaction between a healthy diet and environmental pollutants, which is studied together with internal collaborators. On top of research, training interns, Master and PhD students is also an important task, in addition to lecturing at the University of Luxembourg. Torsten Bohn also hosts the International Journal for Vitamin and Nutrition Research

“Micronutrients and secondary plant compounds
do influence us in many ways. While micronutrients
are truly essential for bodily functions, many
secondaryplant compounds have been associated
in epidemiological studies with health benefits.
However, their mechanism of action is still discussed,
and could include direct anti-oxidant effects,
but also and especially activity on the cellular level via transcription
factors and nuclear factors. Last but not least, many of these compounds
do interact with the microbiota, which may result in additional
health benefits”, explains Torsten Bohn,  PhD, Group Leader of NutriHealth.
