title: Investigating the effect of black tea consumption during pregnancy on the oxidant/antioxidant status of breastmilk.
abstract: OBJECTIVE
  Black tea is associated with antioxidant properties. The objective of this study was to investigate the effect of the amount of black tea consumption during pregnancy on the oxidant/antioxidant status of breastmilk.
  
  
  METHODS
  Breastmilk was obtained from 30 mothers and analyzed for lipid peroxidation based on levels of malondialdehyde (MDA) and of reduced glutathione (GSH). In a survey completed by all participants, daily black tea consumption during the pregnancy was reported.
  
  
  RESULTS
  No correlation was found between the amount of black tea consumed and levels of MDA (p=0.401) and/or GSH (p=0.473). The results of this study indicate that consumption of varying amounts of black tea does not affect the oxidant/antioxidant status of breastmilk.
  
  
  CONCLUSIONS
  The insensitivity of breastmilk to antioxidant contributions by black tea reflects the capacity of breastmilk to be resistant to the myriad of factors that otherwise affect a pregnant woman.
