Recent research from the NIH reveals that blood and urine tests can effectively detect ultraprocessed food intake by analyzing metabolites. Scientists created a biomarker score from samples of older adults, correlating specific metabolites with processed food consumption. A clinical trial further validated these findings, uncovering that metabolites linked to ultraprocessed diets affected various biological pathways. This advancement addresses inaccuracies found in traditional dietary surveys, emphasizing the value of objective biomarkers in dietary assessment and potential health impacts related to ultraprocessed food consumption.
In our study, we found that hundreds of serum and urine metabolites were correlated with percentage energy from ultraprocessed food intake.
It was surprising to find that UPF-correlated metabolites are involved in numerous and diverse biological pathways, underscoring the complex impact of diet on the metabolome.
