Half-Elemental Diet Shifts the Human Intestinal Bacterial Compositions and Metabolites: A Pilot Study with Healthy Individuals

Figure 2

Elemental diet induces persistent changes of the intestinal metabolite profiles varying with each individual. (a) Principal coordinate analysis (PCoA) plots of Euclidean distances demonstrated that metabolite profiles were different between subjects at all time points. (b) PCoA plots for each subject demonstrated metabolite profiles were different between time points. (c) Principal component analysis (PCA) plots demonstrated that different genera were affected by ED between subjects. The top3 loadings of PC1 and PC2 are shown with red arrows and blue arrows, respectively.
