Almost on a daily basis, conflicting results from the latest diet/disease study stir up a media frenzy ― this food is linked to cancer, then it isn’t.

Most diet/disease studies are based on self-reports and are notoriously unreliable. One way to improve accuracy would be to implement the use of biomarkers in nutritional research, as highlighted in an opinion piece published in the Annals of Internal Medicine.

The use of biomarkers measured in urine, blood, or other biospecimens could strengthen assessments of diet, says Ross Prentice, PhD, member of the Cancer Prevention Program in the Clinical Research Division, Fred Hutchinson Cancer Center, Seattle, Washington.

“These biomarkers may be able to be applied directly in disease association analyses, or may be used to calibrate self-report assessments to reduce systematic and random measurement error influences,” he writes.

Important but “Low-Glory Research”

Whether it is feasible to use biomarkers for dietary research is
