An analysis of the fatty acid content of 110 early morning samples of breast milk from 26 mothers shows a shift in the fatty acid pattern toward higher values for C 18:2 fatty acids than those reported previously. This shift has paralleled an increase in the use of vegetable oils and an increase in the P/S ratio of the American diet. The fatty acid pattern varied from day to day only for C 18:1. There were no significant variations among morning, midday, and evening values for samples provided by eight mothers.
对26位母亲的110份清晨母乳样本的脂肪酸含量分析表明，脂肪酸模式出现了变化，C 18:2脂肪酸的值高于先前报道的值。这种变化与植物油使用量的增加以及美国饮食中P/S比值的增加相一致。脂肪酸模式仅在C 18:1方面存在每日变化。八位母亲提供的样本在上午、中午和晚上的值之间没有显著差异。
