A randomized controlled single-blinded three-waycross-over meal study was conducted in 16 overweight men. The intervention meals consisted of sea buckthorn puree, strawberry puree or an iso-caloric control drink.

Only a few common markers appeared for the two berries, and all except one were in very low concentrations and therefore not identified. Nine and 11 markers were(tentatively) identified for strawberry and sea buckthorn, respectively, the most specific being conjugates of aroma compounds and coloring flavonoids. Metabolites reflecting the step-wise aromatization of quinic to hippuric acid were observed after sea buckthorn intake. Three of the identified compounds validate previously proposed exposure biomarkers for the New Nordic Diet, which is high in berries. Potentially common berry exposure markers, as well as an aromatization pathway have been distinguished by human urine profiling after consumption of sea buckthorn or strawberries.
