Results Systolic blood pressure decreased from 144 (SE F1.1) to 134 mm Hg (SE F2, P b .001), and diastolic
blood pressure decreased from 87.4 (SE F1.2) to 83.4 mm Hg (SE F1.2, P b .05). No changes in blood pressure
were demonstrated during placebo periods. Thiobarbituric acid–reactive substances, a lipid peroxidation products
marker, decreased from 4.58 (SE F0.27) to 3.81 nmol/mg (SE F0.32, P b .05). No significant changes were found in
lipid parameters.
