Associations between gut microbiota and host biological parameters after dietary intervention. Heat map of Spearman’s rank correlation coefficients rs (blue = negative rs, red = positive rs). All mice from the three experimental groups at 8 weeks (n = 18) were analyzed. The p-values of the associations were estimated via permutation testing (Monte Carlo procedure). The significant correlations (q < 0.05) are indicated by ‘ + ’; only host variables and bacteria with at least one significant correlation are shown
