New research finds blood glucose and body mass index (BMI) levels in the US are rising, warning of worsening cardiometabolic health despite improving cholesterol and triglyceride levels. The study, which weighed 52,000 participants, represents 264 million adults. Lead author Xiaoning (Jack) Huang, research assistant professor of medicine at Northwestern University Feinberg School of Medicine, tells Nutrition Insight that “up to 80% of the changes in the trends” between birth cohort trends and cardiometabolic health are “not related to BMI.”
