Influence of banana intake and ethanol infusion on plasma SAL and DA in nonalcohol human subjects. Total SAL levels before and after banana intake (A) are shown with time profiles of total SAL levels (B), R / S ratios (C), and DA levels (D). Plasma samples were collected from healthy subjects at various time points; T = −60 (1 hour before banana intake), T = 0 (beginning of ethanol infusion marked with a dashed line; 1 hour after banana intake), and T = 15, 30, 45 minutes (duration of ethanol infusion).
