The effect of lipid diets on the diversity of the gut microbiota. (A) Alpha diversity of colonic microbiota from mice fed high fats diets composed of low-fat chow (blue), milk fat (red), olive oil (purple) or corn oil (green). Observed species richness, Chao1, Shannon’s, and Simpson’s indexes are displayed. (B) PCoA plot of the weighted UniFrac distances of colonic microbial communities from mice fed high-fat diets composed of milk fat, olive oil, corn oil or low-fat chow. The first two principal components from the PCoA are plotted. (C) Statistical summary (p-values after Benjamini–Hochberg adjustment for multiple comparisons) of all alpha and beta diversity measures.
