Can we track what we ate from our blood? From our pee? The Nutri-Markers team from UCD are exploring this as part of the UCD-Nutrimarkers study, gaining a deeper understanding of the link between nutrition and health. The potential for this is huge - no more food diaries for a start. The science of nutrigenomics, metabolomics, is still very much in it's infancy, with advanced testing with DNA and blood analysis.
