Abstract (englisch):
Background:Banana is one of the most widely consumed fruits in the world. However, information regarding its healtheffects is scarce. Biomarkers of banana intake would allow a more accurate assessment of its consumption in nutritionstudies.Objectives:Using an untargeted metabolomics approach, we aimed to identify the banana-derived metabolites presentin urine after consumption, including new candidate biomarkers of banana intake.Methods:A randomized controlled study with a crossover design was performed on 12 healthy subjects (6 men, 6women, mean±SD age: 30.0±4.9 y; mean±SD BMI: 22.5±2.3 kg/m2). Subjects underwent 2 dietary interventions:1) 250 mL control drink (Fresubin 2 kcal fiber, neutral flavor; Fresenius Kabi), and2) 240 g banana+150 mL control drink.Twenty-four-hour urine samples were collected and analyzed with ultra-performance liquid chromatography coupled to aquadrupole time-of-flight MS and 2-dimensional GC-MS. The discovered biomarkers were confirmed in a cross-sectionalstudy [KarMeN (Karlsruhe Metabolomics and Nutrition study)] in which 78 subjects (mean BMI: 22.8; mean age: 47y) were selected reflecting high intake (126–378 g/d), low intake (47.3–94.5 g/d), and nonconsumption of banana. ... mehr
