In a groundbreaking new study, researchers have developed a blood and urine test capable of identifying how much ultra-processed food is in your diet. By analyzing metabolites—chemicals produced as the body breaks down food—researchers can now distinguish between individuals who consume high amounts of ultra-processed foods and those who eat little to none. Listen in this week as Dee discusses the details of this study and how the test works, what it means for the future of nutrition research and personalized nutrition, and how it could help guide healthier food choices.
