Overview

• Published in Applied Physiology, Nutrition, and Metabolism, the study analyzed nearly 16,000 U.S. adults aged 19 and older from NHANES III.
• Higher intake of animal-sourced protein was not associated with increased all-cause or cardiovascular mortality.
• Researchers observed a modest, statistically significant reduction in cancer-related mortality among those consuming more animal protein.
• Exposure was estimated using the National Cancer Institute usual-intake method and multivariate MCMC modeling to better capture long-term diet and reduce measurement error.
• Authors stress the findings are observational rather than causal and note NCBA/Beef Checkoff funding with no stated role in the study’s design, analysis, or publication.
