Associations Between Usual Plant & Animal Protein Intake and Select Serum Biomarkers of Chronic Disease Risk

The prevalence of diet-related chronic diseases has increased significantly in the U.S. over the last two decades, and nutrition interventions may help reduce disease risk. However, studies linking diet with disease risk factors have yet to confirm optimal proportions and sources of certain dietary components such as protein. To identify associations between usual intake of plant and animal protein and serum concentrations of select biomarkers of chronic disease risk, a quantitative statistical analysis was conducted using baseline screening data from a set of controlled feeding trials within the Seattle Dietary Biomarker Development Consortium. The results of this analysis are intended to add to the body of research on this topic and help to inform nutrition recommendations for at-risk individuals.
