title: [The effect of milk products consumption in mothers during breastfeeding].
abstract: BACKGROUND
  Several studies indicate that milk products consumption by mothers during the nursing period induce colic in the newborns. However, when mothers interrupt milk consumption, the colic of the newborns disappears.
  
  
  OBJECTIVE
  to analyze milk composition in Mexican women according to maternal milk products consumption.
  
  
  METHODS
  Seven women were studied in puerperal period, three of them consumed milky products and four not. All were healthy; they gave a five cc milk sample, which was frozen until the moment of the analysis. A double dimension electrophoresis in polyacrilamide gels was carried out. The protein levels were determined by Lowry's method. Total lipid extraction and cromatography in thin plaque was carried out. Total carbohydrate content was quantified.
  
  
  RESULTS
  No differences were found in protein electrophoresis neither in the chromatographic lipid analysis. Carbohydrate content was similar in both groups.
  
  
  CONCLUSIONS
  Colic in newborn depends on the idiosyncrasy of each one, and not in the supposed induced modifications of milk products on maternal milk consumption.
