Uncovering the influence of diet and gut microbiota in human serum metabolome

Metabolomics is the science focused on the study of the metabolism in living organisms. Their aim is tomeasure the metabolites that are the intermediate and final molecules of the biological processes.The entirecollection of the metabolites is called the metabolome. Changes in the biological system would be reflected in the metabolome, since metabolites are involved in the biological functions. The metabolome is affected by the interaction of different factors such as the host, diet, lifestyle, pharmacological treatment and gut microbiota among others. Being the latter one of the most important factors as the gut hosts the largest number of microorganisms in the body (e.g.up to 109 bacteria per gram of luminal content).
