Nutrition, Microbiome, and Chronic Disease: Experts Converge at DGE Congress

At the 63rd Scientific Congress of the German Nutrition Society (DGE) in cooperation with the Technical University of Munich, leading scientists will explore the intricate relationship between nutrition, the gut microbiome, and the development of chronic diseases. The congress, taking place from March 4th to 6th, 2026, in Kassel, will bring together nearly 800 scientists, young researchers, and nutrition experts to discuss current findings in this rapidly evolving field.

Unraveling Causality: A Key Focus

“We are at a point where we know numerous associations between nutrition, microbiome and health, but the crucial question of causality is still open,” states Prof. Dr. Dirk Haller, head of the Chair of Nutrition and Immunology at the Technical University of Munich [1]. Researchers are working to determine whether dietary factors directly influence the microbiome, or if the microbiome dictates our nutritional needs and responses.

Congress Highlights: A Deep Dive into Current Research

The 2 ½ day program features over 200 lectures and posters covering a wide range of topics. Symposia from the DGE specialist groups and working groups, as well as from nutrition and food sciences and related disciplines, will address current research. Key themes include:

• Microbiome-Host Interactions: Exploring the question of “Are we feeding our microbiome or is it feeding us?”
• AI in Public Health Nutrition: Investigating the role of artificial intelligence in optimizing dietary recommendations and public health initiatives.
• Alternative Plant-Based Products: Evaluating the evidence-based benefits and considerations of plant-based alternatives to traditional foods.

Plenary Lectures and Early Career Scientist Showcase

Two plenary lectures will highlight the close links between the microbiome and nutrition, their roles in chronic diseases, and their potential for future diagnostics and therapies. The Early Career Scientists specialist group will also present its 7th Science Slam, showcasing innovative research from emerging scientists.

The Future of Microbiome Research

In a final discussion round, experts will tackle the complex question of what constitutes a healthy microbiome and what interventions can be implemented to promote optimal gut health based on the latest research. This congress represents a critical step towards understanding the causal relationships between diet, the microbiome, and chronic disease, paving the way for more effective preventative and therapeutic strategies.
