An increased adherence to the Western diet may have contributed to the increased prevalence of IBD. An important feature of a Western diet is the high content of sugars and fats. Upon heating of sugar-rich foods, the Maillard reaction is triggered. It is not known to what extent this contributes to adverse health effects in the intestines. Therefore, there is a need for more knowledge on the toxicological effects of Maillard reaction products in the intestines. Is there an epidemiological relationship between the exposure to Maillard reaction products and the onset of IBD?
Job description

Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract characterized by alternating quiescent and active periods (flare ups) of disease. The chronic and excessive inflammation of the gastrointestinal tract results from complex interactions between (1) genetic background, (2) microbiome composition, (3) environmental factors, and (4) mucosal immune responses. Despite the fact that the pathogenesis of IBD is not yet fully known, our diet appears to be one of the major risk factors of IBD. The increased prevalence of IBD is clearly linked to an increased adherence to the Western diet.  

The Western diet is characterized by a higher intake of red meat, fast food, high-fat dairy products, fried and baked foods, sugar-rich drinks and a reduced intake of fiber and whole grains. An important feature of a Western diet is therefore the high content of sugars and fats. Proper heating has an important role in the preparation of our food. Heating for a certain time at a well-chosen temperature kills micro-organisms and inactivates certain enzymes contributing to safe food consumption. However, heating may also contribute to possible negative health effects due to the formation of Maillard reaction products.

With the increased incidence of IBD, the fact that our diet can be a potential trigger for the development of (symptoms as flare ups) of IBD, and the increased consumption of sugar, fat and protein rich foods, a possible link between exposure to Maillard reaction products and inflammatory diseases in the gut is plausible. To date, too little research has been done on this, and there is a need for more knowledge.

We are therefore looking for an enthusiastic PhD candidate to investigate the toxicological relationship between the formation of Maillard reaction products in food products and their local effects in the intestines that could contribute to the development of IBD. This will be done by conducting in vitro toxicological studies with regards to various endpoints (immune effects, microbiome effects and intestinal integrity). Additionally, the epidemiological relationship between exposure to Maillard reaction products and the onset of IBD will be assessed using Food Frequency Questionnaires. The PhD position will be based at Maastricht University in the department of Pharmacology & Toxicology in collaboration with the department of Internal Medicine.

Department of Pharmacology & Toxicology/Department Internal Medicine
This project is situated within the Department of Pharmacology & Toxicology where a multidisciplinary team of biologists, chemists and toxicologists is working together to address mechanisms by which chemicals and oxidative stress alter cellular processes to cause diseases and study the way in which intervention is possible. To reach these goals, the department's laboratory is well equipped with facilities for chemical analysis including mass spectrometry (MS) and electron spin resonance (ESR), the analysis of DNA damage and multiple state-of-the-art molecular biological techniques. The research will be performed in close collaboration with the Department Internal Medicine. The department of Internal Medicine has a broad expertise in the field of nutrition and intestinal health using well-established in vitro gut models and having biological samples of IBD patients to assess the relationship between nutrition and intestinal health.
