RESULTS
After cod intake, serum concentrations of trimethylamine N-oxide (TMAO, p = 0.0043), creatine (p = 0.024) and 1-methylhistidine (1-MeHis, p = 0.014), and urine concentrations (relative to creatinine) of TMAO (p = 2.8 × 10-5), creatine (p = 8.3 × 10-4) and 1-MeHis (p = 0.016) were increased when compared to Control group. After salmon intake, serum concentrations of 1-MeHis (p = 2.0 × 10-6) and creatine (p = 6.1 × 10-4), and urine concentrations (relative to creatinine) of 1-MeHis (p = 4.2 × 10-6) and creatine (p = 4.0 × 10-5) were increased when compared to Control group. Serum and urine concentrations of TMAO were more increased following cod intake compared to salmon intake (p = 0.028 and 2.9 × 10-4, respectively), and serum and urine 1-MeHis concentrations were more increased after salmon intake compared to cod intake (p = 8.7 × 10-5 and 1.2 × 10-4, respectively). Cod and salmon intake did not affect serum and urine concentrations of 3-methylhistidine, and only marginally affected concentrations of free amino acids and amino acid metabolites.
