Professor Haller and His Team (IMAGE) Technical University of Munich (TUM) Caption The composition and function of bacteria in the human intestine -- the so-called gut microbiome -- changes as the day progresses. This was established by researchers based in Freising at ZIEL - Institute for Food & Health of the Technical University of Munich (TUM) with one of the largest studies related to microbiomes and diabetes comprising more than 4000 participants. These daily variations in the gut microbiome cease to exist in people suffering from type 2 diabetes. Credit A.
