This is not particularly relevant to the article but I’ve been thinking lately about the ‘heriditary-ness’ of gut dysbiosis. I believe there is certainly an inherited predisposition but I do not believe it is genetically inherited.
We know that the GI tract is colonised by bacteria from the urinary and vaginal tract during childbirth… so, if the mother has an unfavourable range of bacteria present then she will ‘contaminate’ the baby with these unfavourable strains and perhaps this sets us up for passive immunity (i’m referring to the lack of an immune response due to long-term presence of a pathogen) which is hard to budge.
If it was just a generally poor immune system (inherited genetically) then the lack of resistance to infection would be hugely correlated with all the other conditions that gut dysbiosis is linked to.
I for one (and my mother and sister for two more) am not susceptible to illnesses any more than the average person (probably less infact).
I think parents have a lot of influence over the state of their kids’ guts. Not just what happens during pregnancy or childbirth, but whether or not the kid is breastfed, as well as the quality of the milk, and what kind of exposure the kid has to bacteria (too much cleanliness?) at the critical phase when new strains are being permitted by the body to colonise. Eating habits that influence gut flora late into childhood and beyond could be considered “inherited” too.
Yes, especially the breast feeding. Bifidobacterium growth factors are found in breast milk and who knows what else is in there to be transferred to the child.
