PhD Position in Human Nutrition - Ingredient-specific drivers of gastric emptying and satiety Wageningen • Wageningen University & Research

Seeking a PhD candidate for an interdisciplinary research project exploring how ingredients impact food digestion and appetite. Dive into industry-funded research, utilizing in vitro digestion models, gut imaging, and in vivo assessments. Contribute to ingredient processing and product development. Enjoy excellent terms, including sabbatical, study leave, and sports facilities. Join a vibrant international community on an innovative campus. Competitive salary and growth opportunities await. Read on to find out why we could be the ideal fit for you.

Your job

Are you looking for a PhD position and do you like to participate in an exciting interdisciplinary research project to discover how different ingredients affect food digestion and appetite? Are you a nutritionist or food technologist with interest in digestion, metabolism and the regulation of food intake? Then this PhD position may be of interest to you.

Satiety is experienced as the subjective feeling of fullness following food intake, which hinders further consumption of food. Calorie-matched foods have varying effects on the secretion of appetite-related gut hormones and differ widely in their postprandial satiety effects. Dietary fibers are associated with enhanced satiety and reduced later food intake, but currently the mechanisms of how of different dietary fibers contribute to satiety is poorly understood. The co-ingestion of fibers and bulking agents with specific structures and gelling properties can increase the release of appetite-related gut hormones such as GLP-1 and decrease subsequent food intake. However, in how far these effects are due to slower gastric emptying or other gastric processes, increased production of gut-hormones or both remains unknown.

In this industry-funded partnership project you will do multi-disciplinary work to assess the underlying mechanisms of how different ingredients impact on digestion and subsequent metabolic and appetite effects using established in vitro digestion models, gut imaging techniques, and in vivo assessment of metabolic and appetite effects in healthy volunteers. The acquired knowledge can be used to inform ingredient processing and new product development e.g. aimed at achieving a desirable satiety response.

Your duties and responsibilities include:

• you will conduct in-vitro experiments to measure the (gelling) behavior and breakdown of different ingredients;
• you will conduct human feeding trials with selected ingredients to establish their intra-gastric behavior, gut hormone, and appetite effects in-vivo;
• you will analyse data to establish links between in-vitro and in-vivo digestive behavior, metabolic and appetite responses of different ingredients;
• you will use the knowledge gained to better characterize and explain the metabolic and satiety effects of different ingredients;
• you will publish your research in high-quality academic journals, present it at academic conferences and for other audiences, and publish it as your PhD thesis.

Your team
Your WUR supervisors will be Dr. Paul Smeets and Prof. Dr. Ciarán Forde (Sensory Science and Eating Behaviour chair group). Dr. Davide Risso, external research scientist, will co-supervise.
