Popis:	Background: The bioavailability of isoflavones in children after soy exposure is uncertain. Objective: We aimed to compare isoflavone patterns in infants exposed to isoflavone-containing breast milk (BF), in tofu-fed (TF) infants, and in mothers consuming a soy beverage. Design: Eighteen nursing mothers who were not feeding soy foods totheirinfantsconsumedonedailyservingofasoyproteinbeverage for 2–4 d and collected their own milk and urine and infant urine. Plasma was collected from infants if venous blood draws were ordered by pediatricians. Blood and urine were collected from additionalchildrenaftertheyconsumedtofu.Isoflavonesweremeasured by liquid chromatography–mass spectrometry. Results: In 7 subjects, isoflavone values increased significantly from baseline after mothers ate soy: in maternal urine (x SEM) from18.413.0to135.126.0nmol/mgcreatinine,inbreastmilk
