Impact of fruit and vegetables on oxidative status and lipid profiles in healthy individuals.

Abstract

This study aims to investigate the effect of different amount of low, medium and high (3, 5 and 8 servings/day) fruit and vegetables (F+V) consumption on blood lipid profile and plasma malondialdehyde (MDA) in healthy individuals. In a parallel trial, 63 subjects were randomly assigned into one of the three different dietary interventions. Anthropometric, blood lipid profile and MDA were evaluated at baseline and after 4 weeks intervention. The results showed that consumption of F+V 5 and 8 servings/d could significantly reduce low density lipoprotein (LDL-C) concentrations with a mean difference (95% CI) of -13.28 , (-4.00, - 22.55) and -9.31(-2.25, -16.38) mg/dL respectively. In addition, 8 servings/d of F+V consumption had shown to significantly reduced plasma MDA concentrations with a mean difference (95%CI) of -0.15 (-0.09, -0.2) mg/dL, and p-value <0.05. Therefore, consumption of 8 servings F + V daily pose health benefits on both reducing LDL-C concentrations and improving oxidative status.
