Virginia Tech researchers with the Fralin Biomedical Research Institute published findings Oct. 5 in Nature Metabolism that ultraprocessed and minimally processed meals produce distinct metabolic and brain responses despite matching nutritional profiles. [^2]

Alex DiFeliceantonio, an associate professor at the Fralin Biomedical Research Institute whose lab led the study, stated that population-level data shows people consuming large amounts of ultraprocessed foods have higher rates of poor health outcomes including obesity, cardiac events, type 2 diabetes, and some metrics of mental health. News-Medical reported the comments. [^1]
