title: [Fatty acid composition in breast milk of women from Gdansk and the surrounding district in the course of lactation].
abstract: Breastfeeding is the optimal way of feeding infants and young children. For the human infant, very important ingredients of milk are fatty acids (FA), including long-chain polyunsaturated fatty acids LC-PUFA, which are necessary for the development of human nervous system. The aim of this study was to determine the content and composition of FA in the fat of human milk in the course of lactation, taking into account the composition of FA in mothers' diet.
  
  
  METHODS
  Milk samples were obtained from 80 puerperal women hospitalized in the Obstetrics Department in Gdansk, on the 2nd, 14th, 30th and 90th day of lactation. The mothers were questionnaired about the health state and diet. Based on food frequency questionnaires the content of individual groups of FA in the daily food portions were estimated. The composition and content of FA were determined by HR-GC technique.
  
  
  RESULTS
  In the studied human milk fat about 60 different FA were found. Main FA detected were: oleic, palmitic, linoleic, stearic, myristic and lauric acids. PUFA accounted on average for 13.2% of total FAs. The mean levels of trans FA in the human milk fat was 2.45% of total FAs. Percentage of each group of FA in the diet of the studied population of women averaged to 43.67, 41.74 and 14.59%, for saturated, monounsaturated and polyunsaturated FA, respectively.
  
  
  CONCLUSIONS
  1. Studies have shown that the biggest differences in fatty acid content in the human milk were observed between 2 and 14 day of lactation. 2. A positive correlation and statistically significant eff ect was observed between the composition of particular groups of FAs in human milk and the breastfeeding women's diet.
