Milk fat serves as the main contributor for energy, essential fatty acids and fat-soluble vitamins for exclusively breastfed infants.
Data on fatty acid composition in human milk of Sri Lankan mothers is limited. Present study was conducted to determine
the composition of fatty acids in breast milk during the period of exclusive breastfeeding and to assess whether the fat mass of
lactating mother influences the fatty acid composition of breast milk. In this cross sectional study, milk samples from healthy lactating
mothers (n=48) were collected in three phases of lactation (0-2, 2-4 and 4-6 months) and analyzed by Gas Chromatography with
a flame ionization detector. Mother’s body composition was determined by deuterium dilution technique. Composition of 17 fatty
acids in breast milk was detected. Lauric acid was the most abundant fatty acid (22.3±5.2%) in breast milk of these mothers. Oleic
acid, Palmitic acid and Myristic acid contents were also higher (21.9±4.4, 19.2±2.6 and 15.7±2.7 respectively). The percentages of
C18, C14:1 and C20:3n6 were significantly different between the studied three phases of lactation. Mothers’ age showed a significant
positive correlation with the percentage of Docosapentaenoic acid. Mother’s body weight was positively correlated significantly to the
percentages of C14:1, C16, C18, C18:1c, C20:4n6, C22:5n3 and C22:n3. C16:1 showed positive significant correlations to the %FM
of the mother. Fatty acid composition of the breast milk of Sri Lankan mothers was considerably varied with respect to C8, C18:1t,
C18:3n3, C20, C20:3n6, C20:4n6, C22:5n3 and C22:6n3. Although the percentages of arachidonic acid and DHA were higher, linoleic
and linolenic acid percentages were fairly low. Supplementation of these essential fatty acids during lactation is recommended.
