Abstract

Abstract: Evidence regarding the effect of fruit and vegetable consumption on metabolic syndrome remains inconclusive. Using MEDLINE, EMBASE, and Cochrane, we searched for relevant studies published before 10 December 2013. Of the 383 articles identified, eight randomized controlled trials with 396 participants (205 in intervention groups and 191 in control groups) were included in the final analyses. Fruit and vegetable intake was associated with a reduction in diastolic blood pressure (standardized mean difference: −0.29; 95% confidence interval: −0.57 to −0.02; p = 0.04); however, such intake did not affect waist circumference, systolic blood pressure, fasting glucose, high-density lipoprotein cholesterol, and triglyceride levels in metabolic syndrome patients. In a subgroup analysis, there were no statistically significant differences found according to the intervention period and provision type. Our results suggest an inverse association between fruit and vegetable consumption and diastolic blood pressure in metabolic syndrome patients.
