Results of the pairwise PERMANOVA statistical analysis of beta diversity metrics between high and low fiber content groups of the same diet.

	Pairwise PERMANOVA Results
	WD-High vs. WD-Low (n = 50)	Flex-High vs. Flex Low (n = 52)	VG-High vs. VG-Low (n = 51)	VN-High vs. VN-Low (n = 52)
Beta Diversity	p-Value
Unweighted Unifrac	0.355	0.360	0.130	0.083
Weighted Unifrac	0.113	0.132	0.330	0.151
Bray-Curtis	0.100	0.205	0.034	0.268
Jaccard	0.112	0.280	0.039	0.154

WD = Western Diet; Flex = Flexitarian; VG = Vegetarian; VN = Vegan. Significance levels: p < 0.05, significant; p < 0.01, highly significant.
