PURE: Dairy Intake Linked with Improvements in CVD, Mortality

Consumption of dairy was associated with lower mortality and cardiovascular disease (CVD), according to results from the Prospective Urban Rural Epidemiology (PURE) cohort study.  

Researchers for the study, published September 11 in The Lancet, monitored the dietary dairy intake of 136,384 individuals across 21 countries on five continents. Intake was recorded using validated food frequency questionnaires, with the definition of “dairy products” as milk, cheese, and yogurt. The primary study outcome was a composite of mortality or major cardiovascular events (death from cardiovascular causes, non-fatal myocardial infarction, stroke, or heart failure).  

The analysis recorded 10,567 composite events during its 9.1-year follow-up period. The results suggested that higher total dairy intake was associated with a lower risk for the composite study outcome (HR=0.84; 95% CI, 0.75 to 0·94; Ptrend=0.0004), as well as total mortality (HR=0.83; 95% CI, 0.72–0.96; Ptrend=0.0052), non-cardiovascular mortality (HR=0.86; 95% CI, 0.72 to 1.02; Ptrend=0.046), cardiovascular mortality (HR=0·77; 95% CI, 0.58 to 1.01; Ptrend=0.029), major CVD (HR=0.78; 95% CI, 0.67 to 0.90; Ptrend=0·0001), and stroke (HR=0.66; 95% CI, 0.53 to 0.82; Ptrend=0.0003). Specifically, higher intake of milk and yogurt was associated with a reduction in the composite study outcome.       

“Our findings support that consumption of dairy products might be beneficial for mortality and CVD, especially in low-income and middle-income countries where dairy consumption is much lower than in North America or Europe,” lead study author Dr. Mahshid Dehghan,of McMaster University in Canada, said in a press release.
