Dietary factors play an important role in cognitive development and cognitive decline across the lifespan, and development of neurodegenerative diseases. Evidence-based dietary recommendations are intended to minimize the risk of chronic diseases in the population; however, effective strategies to achieve corresponding long-term changes in dietary behavior in the population are missing.

The cluster, Diet – Body – Brain (DietBB), acts in the region of Bonn-Cologne and includes academic partners, the German Center for Neurodegenerative Diseases (DZNE), the German Nutrition Society, and two industry partners, all located within a radius of 30 km around Bonn.

The proposed cluster, Diet – Body – Brain (DietBB), investigates the relation between dietary factors, particularly food intake and dietary patterns, and the development, maintenance, and decline of cognition across the lifespan, and elucidate the mechanisms underlying the relation between dietary factors and cognition. Furthermore, the cluster investigates determinants of food choices to increase the effectiveness of consumer communication. The DietBB cluster jointly addresses these overarching research questions spanning from in-depth epidemiologic and interventional evidence to recommendations to the public to improve health. These goals are achieved through six thematic areas (TA).


DietBB is funded with a total of 5. 5 million € for 3 years by the BMBF. It is one of four research clusters of nutrition research in Germany:

Enable. Competence Cluster for Nutrition. Healthy food choices in all stages of life
NutriAct. Competence Cluster for Nutrition. Nutritional Intervention for Healthy Aging: Food Patterns, Behavior and Products
NutriCard. Competence Cluster for Nutrition and Cardiovascular Health
