Recent studies from the literature show more and more the interdependence between diet and intestinal microbiome and the health of the human body and the health of the intestinal microbiome.
It has been shown so far that the intestinal microbiome is itself an “organ” that has its metabolic activity influencing the entire metabolism of the body host. In this paper, the main roles of the intestinal microbiome, its composition, and implications in maintaining the health of the organism and the changes in case of existing pathology were pointed out. Our study combines recent in vivo or in vitro tests that have shown a direct link between microbiota imbalances and certain pathologies. Changes in the composition of the microbiome in pathologies such as Alzheimer disease, intestinal or skin pathologies have been described. However, this paper summarizes the main notions and interdependencies between the health of the bacterial intestinal microflora and the health of the human body.
