Blood Type Influences Breast Milk

Blood type and secretor status can influence the breast milk of nursing mom’s.

Mom’s secretor status has a lot of influence on the microbiome of her breast-fed child. The principal sugars in human breast milk are rich in the glycan fucose, but milk from non-secretor moms is much lower in its fucose content. Bifidobacterium longum, a critical early colonizer of the gastrointestinal tract of infants, loves fucose, which is why it grows so readily in breast-fed infants of ABO secretor moms. Non-secretor moms who breast feed infants might benefit using a dietary fucose source as a prebiotic for the infant, or consider consuming sea vegetables, such as seaweeds. Since neuronal attachments are largely mediated through fucose-specific lectin ligands, developmental benefits may also result.
