The flow velocity in our digestive system directly determines how well nutrients are absorbed by the intestine and how many bacteria live inside it. This is the result of a new study by researchers from the Technical University of Munich (TUM) and the Max Planck Institute for Dynamics and Self-Organization (MPI-DS). The researchers revealed the physics mechanisms of how the intestine can regulate itself to optimize nutrient absorption while limiting unwanted bacterial growth at the same time.
