A research by PolyU has revealed that Bifidobacteria, a probiotic, was nearly non-existent in the gut of babies born by cesarean section (C-section). Bifidobacteria is viewed as an essential probiotic for proper immune development and good gut health among infants which protects the neonates from various intestinal and immunity disorders.

Commissioned by Danone Nutricia, PolyU researchers from the Department of Applied Biology and Chemical Technology examined 70 fecal samples of newborn babies after their first 2 weeks of life for the study. They found that the Bifidobacterium species almost did not exist in samples from C-section babies. In comparison, 37 fecal samples from vaginally birthed, breastfed babies had the necessary probiotic levels.

Dr. Chiou Jiachi, Assistant Professor of the Department of Applied Biology and Chemical Technology said 38% of births in Hong Kong are C-section deliveries, so it is crucial to understand the special nutrition needs of C-section babies.
