Higher whole grain consumption is associated with lower total and cardiovascular disease (CVD) mortality, independent of other dietary and lifestyle factors, 2 large prospective cohort studies in the US concluded. The studies included 74 341 women (1984–2010) and 43 744 men (1986–2010). All participants were free of CVD and cancer at baseline and quintiles of whole grain consumption was updated every 2 or 4 years by using validated food frequency questionnaires. There were 26 920 deaths documented during 2 727 006 person-years of follow-up. After multivariate adjustment for potential confounders, including age, smoking, body mass index, physical activity, and modified Alternate Healthy Eating Index score, higher whole grain intake was associated with lower total and CVD mortality but not cancer mortality. Every serving (28 g/d) of whole grain consumption was associated with a 5% lower total mortality or a 9% lower CVD mortality, whereas the same intake level was not significantly associated with lower cancer mortality. Similar inverse associations were observed between bran intake and CVD mortality, whereas germ intake was not associated with CVD mortality after adjustment for bran intake. Whole grain consumption has been consistently found to reduce the risk of type 2 diabetes, cardiovascular diseases as well as colorectal cancer.
