Drinking coffee leaves biomarkers in your body

0

In the search for new biomarkers to study nutrition and health, the research team discovered and characterized three metabolites that can be considered as specific markers that remain in the body after coffee consumption.

These are the breakdown products of a group of substances that are formed in large quantities during coffee roasting, but are rarely found in other foods.

This and the fact that potential biomarkers can be detected in very small amounts of urine make them interesting for future research.

Regarding the amount of coffee consumed, observational studies rely on self-reports from participants, which are difficult to verify.

“Therefore, it would be desirable to conduct additional studies in which coffee consumption could be objectively verified using biomarkers to further determine the health value of coffee,” says Roman Lang, who leads the research team.
