Regarding biomarkers of liver function, levels of total bilirubin, direct bilirubin and indirect bilirubin were unaffected by walnut consumption, although an increasing trend in total bilirubin and indirect bilirubin was observed in participants regardless of their group with a near-significant main effect of time ( p = 0.0505 and p = 0.0729), suggesting that academic stress may lead to a mild increase in total bilirubin levels.
