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

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.
