Biomarkers in Blood and Urine May Reveal Energy Intake from Ultraprocessed Foods, Study Finds
- Erikka Loftfield and colleagues published a study on May 20, 2025, in PLOS Medicine identifying blood and urine markers that reveal ultraprocessed food intake in older U.S. Adults.
- The study built on data from over 1,000 AARP members collected over a year, addressing challenges in accurately tracking ultraprocessed food consumption.
- Scientists identified hundreds of metabolites correlated with ultraprocessed food energy intake and developed scores from 28 blood and up to 33 urine markers predicting consumption reliably.
- Loftfield said the signature is "predictive of this dietary pattern that's high in ultraprocessed food," and Dr. Mozaffarian called the markers "a major scientific advance."
- These findings may illuminate the biological mechanisms connecting ultraprocessed food intake to health effects, and Loftfield plans to utilize this method with current research involving blood and urine samples to examine cancer risk.

Ultraprocessed foods increase risk of dementia, depression and more. Microplastics may be why
The link between a diet high in ultraprocessed foods and poor mental health, as well as cognitive decline, has been well-documented — and a new paper published Tuesday offers a theory about why they are connected.

Markers in Blood and Urine May Reveal How Much Ultraprocessed Food We Are Eating
(MedPage Today) -- Molecules in blood and urine may reveal how much energy a person consumes from ultraprocessed foods, a key step to understanding the impact of the products that make up nearly 60% of the American diet, a new study found. It...
A Blood Test May Reveal the Amount of Ultraprocessed Foods a Person Consumes
Scientists from the United States proposed a method to analyze the intake of these products. Although the research is at an early stage, they stressed that it could be useful to know the effects of this diet on health.
