Dietary acculturation may play a stronger role in some heritage groups compared with others according to a new study by researchers at Columbia University Mailman School of Public Health and The University of North Carolina at Chapel Hill. And that adherence to cultural dietary patterns may be impacted by the number of years lived in the United States. This is the first study to take a data-driven approach using foods specific to a population to empirically derive dietary patterns. The findings are published in The Journal of Nutrition.
