    New Blood Test Can Reveal Your Ultra-Processed Food Intake

    ​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.

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.
