Table 3.

Genotoxicity and cytotoxicity found in fecal water samples of omnivores (n = 14), lacto-ovo-vegetarians (n = 24), and vegans (n = 20).

Biomarker	Omnivores	Lacto-ovo-vegetarians	Vegans	p-value^∗
Genotoxicity (tail intensity)^a	2.08 ± 0.97^A	0.92 ± 0.46^B	1.49 ± 0.68^A	0.014
Cytotoxicity (percent dead cells)^b	19.86 ± 8.38^A,C	14.25 ± 3.83^A,B	25.70 ± 13.63^C	0.043

Mean values ± SD obtained from samplings carried out in two consecutive weeks. ^∗One way ANOVA. Homogeneity of variances was checked using Bartlett’s test. ^A,B,CValues in a row with different superscript letters are significantly different (p < 0.05) according to Bonferroni’s multiple comparison post-test. ^aComet assay, ^bTrypan blue exclusion.
