Research has shown that breastfed infants have a high abundance of beneficial bacteria, such as bifidobacteria.1-3 Infants breastfed by secretor mothers with higher levels of 2-fucosylated HMOs, such as 2’FL, in their breast milk had a higher abundance of beneficial bifidobacteria and lower levels of Streptococcus in comparison with infants of non-secretor mothers.4\r\rReferences:\r\r\r Collado MC, Cernada M, Baüerl C, Vento M, Pérez-Martínez G.
