We conducted this study to determine the fatty acid composition of breastmilk of Israeli women and compare it with baby milk substitutes. Samples of mature breast milk, from 29 lactating Israeli Jewish mothers were collected during feedings. Total milk lipids extracts were transmethylated and analyzed by using an improved gas-chromatographic method. About 72% of the total fatty acids in the investigated breast milk comprised oleic (18:1c; 31±4%), palmitic (16:0; 21±4%), and linoleic (18:2n-6; 20±4%) acids. Total saturated fatty acids represented 42±7% of total fatty acids. The monounsaturated fatty acids content was 33±5%, of which 94% was oleic acid, and the polyunsaturated fatty acids content was about 24±4%, of which 85% was linoleic acid. The a-linolenic acid level found in this study, 2.0±0.6%, was higher than the range of values reported for the world population (0.10-1.4%). The main fatty acids composition of the milk substitutes has very similar composition to the breast milk. Docosahexaenoic acid levels are particularly low among the population of Jewish nursing mothers in relation to the milk substitutes, containing docosahexaenoic acid in their formulations.
我们进行这项研究，以确定以色列妇女母乳的脂肪酸组成，并将其与婴儿配方奶进行比较。从 29 名以色列犹太哺乳期母亲的喂养过程中收集成熟母乳样本。通过使用改良的气相色谱法对总乳脂提取物进行了转甲基化和分析。在所研究的母乳中，约 72%的总脂肪酸由油酸（18:1c；31±4%）、棕榈酸（16:0；21±4%）和亚油酸（18:2n-6；20±4%）组成。总饱和脂肪酸占总脂肪酸的 42±7%。单不饱和脂肪酸含量为 33±5%，其中 94%为油酸，多不饱和脂肪酸含量约为 24±4%，其中 85%为亚油酸。本研究中发现的 α-亚麻酸水平（2.0±0.6%）高于世界人口报告的范围（0.10-1.4%）。与配方中含有二十二碳六烯酸的配方奶相比，哺乳期犹太母亲的主要脂肪酸组成与母乳非常相似。人群中二十二碳六烯酸的水平特别低。
