Essential fatty acids (EFA), including linoleic acid (LA) and alpha‐linolenic acid (ALA), are indispensable for proper brain growth especially in the first months after birth when it develops most rapidly. Since fats, especially EFA, in breast milk are highly variable between mothers, we indirectly examined whether milk energy, LA and ALA content in breast milk affect volume and shape of the infant's head.

母乳中能量和必需脂肪酸含量对婴儿头部尺寸的影响。

必需脂肪酸（EFA），包括亚油酸（LA）和α-亚麻酸（ALA），对于大脑的正常生长是必不可少的，尤其是在婴儿出生后的头几个月中，它发展最快。由于母乳之间的脂肪（尤其是EFA）差异很大，因此我们间接检查了母乳中的乳汁能量，LA和ALA含量是否会影响婴儿头部的大小和形状。
