Investigation of Potential Food Intake Biomarkers by LC-MS/MS: Suitability Under Conditions Close to Everyday Live.
Article in Molecular nutrition & food research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
scopeFood intake biomarkers are proposed to be a more reliable tool for investigating the nutritional status compared to food diaries or food frequency questionnaires. Nevertheless, biomarkers have some disadvantages such as the influence of the individual lifestyle, different metabolism, nutrient-nutrient interaction or the specificity of the used biomarkers. To evaluate the suitability of several biomarkers, a study under conditions close to everyday life was conducted. METHODS AND
resultsTen healthy volunteers were divided into three groups who followed different meal plans for 24 h and collected their entire urine. Afterward, several potential biomarkers were quantified using an LC-MS/MS approach. To further investigate the suitability of those biomarkers, the results were investigated with the main goal of grouping the participants according to their provided diet, while the first author did not have any knowledge of the meal plans or other specific knowledge about the study design.
conclusionThe use of different biomarkers enables the evaluation of different eating habits without any prior wash out period or bigger than usual portion sizes. Especially long-term biomarkers seem to have a good suitability. Very high intakes and very low intakes are easier to distinguish than a moderate intake. Food intake biomarkers are proposed as a more reliable tool than food diaries or food frequency questionnaires. Nevertheless, data under realistic conditions are rarely available. In this study, ten volunteers were divided into three groups with different meal plans. An LC-MS/MS approach was performed and the data were further investigated with the main goal of grouping the participants according their provided diet, while the first author did not have any knowledge about the meal plans.
