New research on how maternal BMI, glucose tolerance status, mode of birth and ethnicity influence the diversity of microbes in breast milk

 New research on how maternal BMI, glucose tolerance status, mode of birth and ethnicity all influence the diversity of microbes that are in breast milk.

A couple of interesting points:

- Women with a pre-pregnancy BMI > 30 kg/m2 (obese) had a greater incidence of Bacteroidetes and a reduced incidence of Proteobacteria in their milk, compared to women with an overweight BMI.

- An increased incidence of Brevundimonas was found in the milk of women who underwent an unscheduled C-section versus vaginal delivery.

“Human milk has a diverse microbiota of which its diversity and differential abundance appear associated with maternal BMI, glucose tolerance status, mode of delivery, and ethnicity”
