Abstract:

The gut microbiota is a bridge between diet and human health, acting as an important “microbial organ” in the
human body, and is related to nutrient absorption and metabolism. Meanwhile, researchers have already gained attention due
to the important role of this “microbial organ” associated with health and disease as well as diverse physiological functions.
In this paper, we summarize the effect of diet on the structure and metabolites of the gut microbiota, the relationship between
the gut microbiota and physiological functions, and the association with the gut microbiota and human health. It could be
helpful for us to understand the association of diet with the gut microbiota and human health.

Key words: gut microbiota, diet, health, metabolite, metabolic syndrome, obesity
