While a wealth of data on the fatty acid composition of mature human milk has been published, limited information is available on the quantities of individual fatty acids supplied to the suckling infant with maternal milk, through the whole first year of life. Our aim was to qualitatively and quantitatively evaluate the fatty acid composition of human milk from Italian mothers, throughout extended lactation with particular emphasis on the long-chain polyunsaturated fatty acids. We have thus measured the total fat content and the concentrations of major fatty acids by quantitative GLC in pooled breast hindmilk collected from all feedings over 24 h at colostrum, 1, 3, 6, 9 and 12 months in ten mothers recruited after delivery of full-term infants. Total saturated fatty acids progressively increase and total monounsaturated progressively decrease as percentage levels, while among long-chain polyunsaturated fatty acids, percentages of arachidonic acid and docosahexaenoic acid decrease from colostrum up to the third month. Hindmilk total lipids (mg/dl) rise more than twofold up to 3 months, and then remain stable. The amounts (mg/dl) of linoleic acid and α-linolenic acid progressively increase, following the trend of total fat, while arachidonic and docosahexaenoic concentrations (mg/dl) remain stable throughout the whole nursing period. Assessment of the intakes per kg body weight shows different trends for the individual major long-chain polyunsaturated fatty acids supplied to the infant from hindmilk during exclusive breast-feeding (3 months). This information may be useful for the evaluation of infant intakes during extended lactation.

An experimental study was carried out with the aim of evaluating the quality of the lipid fraction of Serbian biscuits. Total fat contents of the biscuit samples ranged between 10.2% and 24.5%. The saturated, cis-monounsaturated and cis-polyunsaturated fatty acid contents were within the ranges of 18.585.6%, 10.649.9% and 2.713.3% of total fatty acids, respectively. The content of trans fatty acids (TFA) ranged from 0.0% to 42.5% and the mean was 10.2%. In a total of 34 investigated samples, 10 of them were found to be trans - free, 8 contained low level of TFA (under 2%), 4 samples contained between 2 and 10% of TFA, while 12 samples contained very high amounts of TFA (12.042.5%). The results obtained showed a considerable variability in fatty acid composition of biscuits which indicated that different types of fats and oils were used for production of biscuits in Serbia.

Total fat and fatty acid composition of seven fresh-water and nine marine fish commercially important in Brazil were determined. Palmitic acid was the predominant saturated fatty acid in both freshwater and marine fish. In the fat from freshwater fish the total C-16 fatty acids were higher than in marine fish. Oleic acid was the most abundant monounsaturated fatty acid and it was found in higher levels in freshwater fish. The data revealed that most freshwater fish from Brazil examined were a poor source of eicosapentaenoic (20:5) and docosahexaenoic (22:6) acids. Of the marine fish analysed, only sardine and manjuba could be recommended as a good sources of n-3 fatty acids.

Background: Human milk is a rich source of omega-3 long-chain polyunsaturated fatty acids, which are postulated to be important for brain development. There is a lack of data on the human milk fatty acid composition of Cambodian women compared with data from Western women. Research Aim: The aim of this study was to determine the human milk fatty acid composition of women living in Cambodia and compare it with that of women living in Australia. Method: Human milk samples from Cambodian ( n = 67) and Australian ( n = 200) mothers were collected at 3 to 4 months postpartum. Fatty acid composition was analyzed using capillary gas chromatography followed by Folch extraction with chloroform/methanol (2:1 v/v), and fat content was measured gravimetrically. Result: Compared with Australian participants, human milk from Cambodian participants contained a significantly lower level of total fat (2.90 vs. 3.45 g/dL, p = .028), lower percentages of linoleic acid (9.30% vs. 10.66%, p < .0001) and α-linolenic acid (0.42% vs. 0.95%, p < .0001), but higher percentages of arachidonic acid (0.68% vs. 0.38%, p < .0001) and docosahexaenoic acid (0.40% vs. 0.23%, p < .0001). Conclusion: Differences in human milk fatty acid composition between Cambodian and Australian participants may be explained by differences in the dietary patterns between the two populations.
