Body adiposity shifts gut microbiota patterns within dietary patterns. a Relative abundance of bacterial species in different fecal samples is visualized by bar plots. Each bar represents a subject and each colored box a bacterial taxon. The height of a color box represents the relative abundance of that organism within the sample. “Other” represents lower abundance taxa. Lean Mediterranean diet-fed subjects are shown in dark blue; heavy Mediterranean diet-fed subjects are shown in light blue; lean Western diet-fed subjects are shown in dark green; and heavy Western diet-fed animals are shown in light green. b Lean Mediterranean diet-fed animals display higher Lactobacillus animalis abundance when compared to heavy Mediterranean diet-fed subjects, lean Western diet-fed subjects, and heavy Western diet-fed subjects. Lean Western diet-fed monkeys displayed increased gut abundance of Bacteroides uniformis (c) when compared to heavy animals fed the same diet. Heavy Western diet-fed subjects displayed increased Ruminococcus champaneliensis (d) when compared to the relative abundance of these species within lean Western diet-fed NHPs. n=7-8. *p from pairwise comparison in two-way ANOVA diet × group interaction used alpha=0.10. Error bars show the min to max distribution
