I was reading in a book about IBS written by Professor John Hunter that the gut is sterile in the first couple of weeks. If I remember right the gut is colonised by gut bacteria from the family members within 6 weeks. Bacteria coming from Mom, dad and sibling will enter the child and after that the immune system will react to any additional bacteria and reject these. If the child or later the adult looses the good bacteria and wishes to fill up the lost specimen then ONLY the bacteria which got the marking as being “good” bacteria will be able to survive and attach itself to the guts. That means even if we push in other “good” bacteria, our body will only recognise these as friendly which got their markers as being friendly in the first 6 to 8 weeks.
I wonder if that explains why I get violent reactions to probiotics, much like an allergic reaction. He is not making the conclusion. He even says that probiotics are good and can help but I doubt they would colonise if they haven’t been marked as friendly from the beginning of your time as a baby. In that way probably getting fecal planting from your mother would be best. Why it is good to get a wide spectrum probiotic I guess is that you are more likly to have a homerun with some of the bacteria then buying a single spectrum and maybe buying just one which never was a part of your system.
What do you think about that Djorge? Do you have any information? I am mainly interested in my thoughts about even good bacteria will not do good if it never has been marked as friendly in the first 6 weeks and the thought about that only bacteria which had been marked as friendly from your immune system will be allowed to attach itself to the gut.
