Whole pecans and phenolic extract of pecans improves the gut microbiota. (A) Observed species, (B) Chao1, (C) Shannon index, (D) Beta-diversity, (E) Phyla diversity, (F) Taxonomy level and (G) Serum LPS in mice fed the Control diet (Control), a High-fat diet (HF) or a High-fat diet with whole pecans (HF WP), or a High-fat diet with phenolic extract, 3 mg (HF 3PP) or 6 mg (HF 6PP). Results are presented as the mean ± S.E.M., n = 6 mice per group and analyzed by one-way ANOVA followed by the Tukey multiple comparison post hoc test. The differences were considered statistically significant at p < 0.05. Mean values with different lowercase letters show statistical differences between each other, where a > b.
