Across the world, consumption of foods with a high glycemic index was a predictor of cardiovascular disease (CVD) and death, researchers reported from an observational study.
Compared with people eating foods with a low glycemic index, those eating higher-ranking carbohydrates were at greater risk of CVD events, such as CV death, MI, stroke, and heart failure, and all-cause mortality over a median 9.5 years of follow-up.
This was true whether study participants had preexisting CVD at baseline (adjusted HR 1.51, 95% CI 1.25-1.82) or not (adjusted HR 1.21, 95% CI 1.11-1.34), according to David Jenkins, MD, PhD, of the University of Toronto, and colleagues in the PURE group.
