a ATNC levels in faecal water (Mean ± standard error of the mean (SEM); μmol/L) at baseline, after the low drinking water (< 1.5 mg/L) and after the high drinking water (ADI levels) period for the processed red meat group and unprocessed white meat group. ATNC levels and urinary nitrate excretion significantly increased after the high drinking water period in both the processed red meat group and unprocessed white meat group (** p < 0.01, * p < 0.05, respectively); b Nitrate levels in urine (Mean ± SEM; μmol/day) at baseline, after the low drinking water and after the high drinking water period for the processed red meat group and unprocessed white meat group. Urinary nitrate excretion significantly increased after the high drinking water period in both the processed red meat group and unprocessed white meat group (* p < 0.05, *** p < 0.001, respectively)
