A study at Sweden's Lund University shows that infants who have an imbalanced intestinal bacterial flora a week after birth are more likely to develop eczema.
The composition of a child’s bacterial flora is dependent on the mother’s microflora, since she is the primary source for the child’s bacteria at the outset.Only it turns out that 1/3 of US women are short of lactobacilli, resulting in an imbalance in their vaginal bacterial flora, that may get passed on to their kid.
“A healthy vagina is totally dominated by lactobacilli, or lactic acid bacteria. With a vaginal delivery the child will come into close contact with the mother’s bacteria. If the mother has a good flora of bacteria, the contact is an important help for the child to be able to be colonized by bacteria in the proper way," [said Göran Molin, professor of food hygiene at the Faculty of Engineering, Lund University, who co-directed the study with Siv Ahrné, also a professor of food hygiene.]
Or not, as Clive speculates in his post on this study; with the steady increase in C-sections in the US, more and more infants may get no exposure to their mothers' vaginal bacterial flora at all.
I'd hoped to discuss some of the sources of these healthy, probiotic lactobacilli, but I'm afraid I've already maxed out my 10-year quota on the phrase, "vaginal bacterial flora." All I can say is "sauerkraut."
