The digestive tract is an extraordinary tool for transforming matter. As it

is highly compact and adaptable, it ensures the transformation of ingested foods

into nutrients that can be absorbed by our digestive mucosa through mechanical,

chemical, biochemical and biological processes. INRA currently possesses a

combination of knowledge and tools that make it possible to integrate all of

these events to create an in silico model of the fate of food in the digestive

tract. The aim is to improve our knowledge about the digestive process: What is the role of the "structure" of a food at different scales, on the availability kinetics of "molecules of interest" during digestion, and what are their effects on humans?
