The total amount of fat in the milk of nursing mothers depends on maternal reserves, as well as food intake and its synthesis in the mammary glands. The aim of this study was to assess the contents of fatty acids in the milk of women from the West Pomeranian region of Poland with regards to supplementation and the amount of adipose tissue. We also wanted to find out whether these women, who have direct access to the sea and potential access to fresh marine fish, have higher levels of DHA.
We analyzed milk samples obtained 6-7 weeks postpartum from 60 women. The content of fatty acid methyl esters (FAME) in lipids was determined by gas chromatography-mass spectrometry (GC/MS) using a Clarus 600 device (PerkinElmer).
Women using dietary supplements had significantly higher levels of docosahexaenoic acid (DHA) (C22:6 n-3) ( = 0.000) and eicosapentaenoic acid (EPA) (20:5 n-3) ( = 0.000). The levels of eicosatrienoic acid (ETA) (C20:3 n-3) and γ-linolenic acid (GLA) increased with the amount of body fat, and the level of DHA was lowest in subjects where body fat exceeded 40% ( = 0.036).
The contents of fatty acids in the milk of women from the West Pomeranian region of Poland were similar to that reported by other authors. The levels of DHA in women using dietary supplements was also comparable to the values reported worldwide. BMI had an effect on the levels of ETE and GLA acids.
哺乳期母亲乳汁中的脂肪总量取决于母体储备,以及食物摄入及其在乳腺中的合成。本研究的目的是评估波兰西波美拉尼亚地区妇女乳汁中的脂肪酸含量,以及与补充剂和脂肪组织量有关的含量。我们还想了解这些妇女是否有直接接触海洋和潜在获得新鲜海洋鱼类的机会,因为她们体内的二十二碳六烯酸 (DHA) 含量是否更高。
我们分析了 60 名产后 6-7 周妇女的乳汁样本。使用 Clarus 600 设备(PerkinElmer)通过气相色谱-质谱法(GC/MS)测定脂质中脂肪酸甲酯(FAME)的含量。
使用膳食补充剂的妇女的二十二碳六烯酸(DHA)(C22:6 n-3)( = 0.000)和二十碳五烯酸(EPA)(20:5 n-3)( = 0.000)水平显著更高。二十碳三烯酸(ETA)(C20:3 n-3)和 γ-亚麻酸(GLA)的水平随着体脂量的增加而增加,而 DHA 水平在体脂量超过 40%的受试者中最低( = 0.036)。
波兰西波美拉尼亚地区妇女乳汁中的脂肪酸含量与其他作者报道的相似。使用膳食补充剂的妇女的 DHA 水平也与全球范围内报告的水平相当。BMI 对 ETE 和 GLA 酸的水平有影响。
