HealthDay News — Consumption of a plant-centered, high-quality diet starting in young adulthood is associated with a lower risk for cardiovascular disease (CVD), while a higher adherence to the plant-based Portfolio Diet is associated with a reduction in CVD events among postmenopausal women, according to two studies published online in the Journal of the American Heart Association.
Yuni Choi, PhD, from the University of Minnesota-Twin Cities in St Paul, and colleagues examined the association between cumulative intake of a plant-centered diet with incident CVD among 4946 adults in the Coronary Artery Risk Development in Young Adults prospective study who were initially 18 to 30 years old and free from CVD. During 32 years of follow-up, the researchers identified 289 incident CVD cases. The risk for CVD was lower with both long-term consumption and a change toward such diet. Comparing the highest quintile of the time-varying average A Priori Diet Quality Score to the lowest quintiles yielded a multivariable-adjusted hazard ratio of 0.48.
Andrea J Glenn, RD, from the University of Toronto, and colleagues followed 123,330 postmenopausal women initially free of CVD from 1993 to 2017. The researchers found that adherence to the Portfolio Diet was associated with a lower risk for total CVD, coronary heart disease, and heart failure when comparing the highest to lowest quartile of adherence and after multiple adjustments (hazard ratios, 0.89, 0.86, and 0.83, respectively). No association was noted for stroke or atrial fibrillation.
“Our results support the Portfolio Diet as another therapeutic dietary approach for managing CVD risk that fits with current guidelines emphasizing plant-based diets,” Glenn and colleagues wrote.
