Sets of metabolites found in blood and urine reliably correspond with how much energy from ultra-processed food (UPF) a person consumes, according to a new study published in the open-access journal PLOS Medicine by Erikka Loftfield of the National Cancer Institute, USA and colleagues.
“The identified poly-metabolite scores could serve as objective measures of UPF intake in large population studies to complement or reduce reliance on self-reported dietary data,” the authors say. “Poly-metabolite scores should be evaluated and iteratively improved in populations with diverse diets and a wide range of UPF intake.”
