“higher consumption of fruit and vegetables is associated with a reduced risk of all-cause mortality”
The Answer is a resounding YES: What is common sense, even your grandmother knows, is now “proven” in a study.
According to a recent study published in The British Medical Journal (BMJ), “[h]igher consumption of fruit and vegetables is associated with a reduced risk of all-cause mortality, with an average reduction in risk of 5% for each additional serving a day (6% for fruit and 5% for vegetables).”and Reduction CV disease
A meta-analysis of 16 prospective cohort studies demonstrated that the “average reduction in the risk of cardiovascular disease mortality was 4% (hazard ratio 0.96, 95% confidence interval 0.92 to 0.99; P=0.02) for each additional serving per day of fruit and vegetables combined, 5% (0.95, 0.91 to 1.00; P=0.03) for fruit consumption, and 4% (0.96, 0.93 to 0.99; P=0.01) for vegetable consumption.”
