摘要

Sugars are more and more replaced with low- or non-calorie sweeteners. This change in diet does not only affect our own caloric intake but also the nutrients provided to our gut microbiota. The relationship between humans and their gut microbiota is mutualistic and the microbiota has an influence on the development of a wide variety of diseases such as obesity, type Ⅱ diabetes and cancer. As such, diet changes affect our health in several ways through the effect on the gut microbiota. Consequently, an interesting approach would be to focus on characterizing and modeling the effect of a diet change, from high to low caloric content, on the behavior of a complex population of gut microbiota. On the other hand, realistic experiments (i.e., experiments that could also be performed in vivo) can be designed to estimate parameters which cannot be easily fixed upfront. In this article a review is presented on the current state of the art of model system development for microbial and physicochemical processes in the human small intestine. The emphasis is on how gut microbiota dynamics are influenced by a diet shift. The authors propose a novel process systems engineering approach for investigating the influence of a low calories diet change on gut microbiota dynamics.
