From: Variable responses of human and non-human primate gut microbiomes to a Western diet
A Western diet reduces gut microbial diversity in humans but not vervets. Chao1 estimates (average ± SD) of microbial community richness at 1000 sequence reads per sample for vervets and humans consuming a non-Western vs. a Western diet. Star indicates significant differences (FDR-corrected p < 0.05) in microbial richness between diets. Western humans are from Italy (Schnorr et al. [3]) and the USA (Yatsunenko et al. [2]). Non-western humans are from Tanzania (Hadza, Schnorr et al. [3]), Venezuela (Guahibo, Yatsunenko et al. [2]), and Malawi (Yatsunenko et al. [2]). (N = 13 non-Western vervets; N = 14 Western vervets; N = 17 non-Western (Schnorr et al.) humans; N = 11 Western (Schnorr et al.) humans; N = 76 non-Western (Yatsunenko et al.) humans; N = 118 Western (Yatsunenko et al.) humans)
