Abstract
The fatty acid (FA) composition of samples of breast milk obtained from well-nourished Sudanese women was determined by capillary gas chromatography. Saturated fatty acids (SFA) constituted 46%, monoenoic acids (MONOENE) 33% and polyunsaturated fatty acids (PUFA) accounted for 21% of total fatty acids. The mean value (18.28%) of the essential fatty acid linoleic acid was comparable to the levels reported for well-nourished mothers from industrialised countries. The proportions of fatty acids synthesised de novo in the mammary gland (10:0, 12:0, 14:0) were less than expected from published studies of mothers consuming low fat diet averaging 17.4%. The amount of 22:6 n-3 which is synthesised from 18:3 n-3 and also taken up by consumption of fish were found to be low. The possible nutritional implications of the low n-3 fatty acids for the infants should therefore be investigated.
