Five Servings of Fruit and Veggies a Day Cut Mortality

TUESDAY, Aug. 5, 2014 (HealthDay News) -- Consuming five or more servings of fruit and vegetables daily is associated with reduced risk of all-cause mortality, particularly cardiovascular mortality, according to research published online July 29 in BMJ.
Xia Wang, of Shandong University in Jinan, China, and colleagues conducted a systematic review of the literature and performed a meta-analysis of data from 16 prospective cohort studies involving 833,234 participants. The authors sought to assess the dose-response relationship between fruit and vegetable consumption and the risk of mortality.
The researchers found that the risk of all-cause mortality was reduced for each daily serving of fruit and vegetables (pooled hazard ratio [pHR], 0.95; 95 percent confidence interval [CI], 0.92 to 0.98; P = 0.001), fruit (pHR, 0.94; 95 percent CI, 0.90 to 0.98; P = 0.002), and vegetables (pHR, 0.95; 95 percent CI, 0.92 to 0.99; P = 0.006). At a threshold of five servings of fruit and vegetables daily, no further reduction in the risk of all-cause mortality was observed. Each additional serving of fruit and vegetables per day was associated with decreased risk for cardiovascular mortality (HR, 0.96; 95 percent CI, 0.92 to 0.99), but not cancer mortality.
"This meta-analysis provides further evidence that higher consumption of fruit and vegetables is associated with a lower risk of mortality from all causes, particularly from cardiovascular diseases," the authors write.
