Relationship of dietary macronutrient intake with the relative abundance of bifidobacteria and lactobacilli in breast milk of normal-weight mothers compared to the obese: a case-control study.

ABSTRACT:

Background

Lactobacillus and Bifidobacterium are members of the probiotic bacteria with many health benefits. Breast milk is an important source of these beneficial genera, which are affected by several factors. In the present study, the population of these genera was measured in milk of obese vs. normal-weight lactating women and their relationship with dietary macronutrient's intake was investigated.

Methods

Twenty women with high body mass index (BMI) enrolled as obese (≥ 30 kg/m2) and 20 women with normal BMI (18.5-24.9 kg/m2) were selected as controls.

DNA was extracted from milk. The population of
