Our gut is colonized by a variety of bacteria at birth. During the first years of life develop these into a relatively stable ecosystem – our normal intestinal flora.
By studying how gut flora develops in nearly 100 babies born at Halmstad County Hospital and comparing the intestinal flora of their mothers Researchers at the University of Gothenburg managed to get a more detailed picture of this process.
The study, conducted in collaboration with Halmstad County Hospital and researchers in China, shows that babies born by Caesarean section inherits fewer bacteria from their mothers.
– More surprisingly seems to weaning from breast milk have great influence of intestinal microflora composition, and even greater impact than the introduction of solid foods, says professorena Fredrik Bäckhed and Jovanna Dahlgren at Sahlgrenska Academy:
– We see that when you introduce solid foods and baby continues delammas changing the intestinal flora to a lesser extent and in a more favorable way than if the baby stops breast-feeding altogether.
The current study the researchers broadened the understanding of how we interact with the millions of bacteria our bodies harbor – bacteria which produces amino acids and vitamins that the body needs.
– The current study lays the foundation for further studies of how individual person’s intestinal flora can predict who is at an increased risk for common diseases, says Fredrik Bäckhed.
