People who choose whole grains over refined grains lower their risk for dying prematurely, state researchers at Soochow University in China. In this meta-analysis of 33 studies, the association between whole grain consumption and risks of dying from any cause, heart disease, and cancer was assessed. Results showed that consuming at least 50 grams of whole grains a day resulted in a 22% decrease in death from any cause, a 30% decrease in heart disease deaths, and an 18% decrease in cancer deaths. The researchers conclude that as whole grain consumption goes up, the risk of dying prematurely from any cause goes down.
