Sponsor's own description

The Seattle Dietary Biomarker Development Center (S-DBDC) aims to advance the science of measuring dietary intake by identification and validation of dietary biomarkers that improve upon self-reported diet. To accomplish this mission, the Seattle DBDC will carry out controlled feeding studies in healthy human volunteers. Metabolomics assays will be conducted on blood and urine specimens collected during the feeding studies for biomarker identification.
