Abstract

Background Coffee is a widely consumed beverage, and studies suggest that drinking coffee has beneficial health effects. The phytohormone trigonelline is present in large amounts in coffee beans, and circulating concentrations of trigonelline have been shown to be positively related to dietary intake of coffee and to increase significantly after the consumption of a bolus dose of coffee.Objective We cross-sectionally investigated the utility of plasma trigonelline as a marker of coffee consumption in an epidemiologic setting. We secondarily investigated if coffee intake is related to plasma concentrations of vitamin B-3 (niacin) forms.Design In a Norwegian cohort of 3503 participants, we combined questionnaire data on the number of cups of coffee consumed per day with plasma trigonelline to evaluate trigonelline as a marker of coffee intake. The suitability of plasma trigonelline to discriminate those not consuming from those consuming coffee was investigated by receiver operating characteristic (ROC) analysis. Plasma collected at 2 time points 1 y apart was used to determine the within-person reproducibility of trigonelline.Results We found that plasma trigonelline concentrations increased strongly with increasing amounts of coffee consumed. ROC analysis showed that trigonelline had an area under the curve of 0.92 (95% CI: 0.90, 0.94) for distinguishing coffee abstainers from coffee drinkers. Plasma trigonelline had a good within-person reproducibility (0.66; 95% CI: 0.64, 0.68) for samples collected 1 y apart. The amount of coffee consumed was not associated with plasma concentrations of the niacin vitamers nicotinamide and N1-methylnicotinamide.Conclusions Plasma trigonelline performs well as a marker of coffee intake. Data used in this study were derived from the clinical trial registered at www.clinicaltrials.gov as NCT00354081.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
