The alpha- and beta-diversity of the gut microbiota collected from LF-PF and HF-HP diet groups. Alpha-diversity analysis based on Shannon index (A), Observed OTUs (B), Faith’s index (C) and Evenness index (D). Beta-diversity analysis based on Unweighted unifrac distance (E), Weighted unifrac distance (F and I), Jaccard distance (G) and Bray–Curtis distance (H and K). Each point represented a sample with different color. Red and green curves were respectively composed of HF-HF and HF-HP diet healthy subjects
