So the one the most obvious one I guess is type one diabetes and we've known for some time that there are these associations with early life exposure to dairy protein and developing type one diabetes. This is not proven yet. It appears that A2, the A2 protein compared to the A1 might not elicit the same response, but it's because later the body recognises the protein that it's been exposed to, which looks a bit similar. To the to the beta cells and it kills off your own beta cells that make insulin, and you can't make insulin and you get type one diabetes. So again, it's happening because things are getting in through the gut and there's word sometimes they used to call it little gut. You've gone by, I think naturopaths use that word, but it makes sense. It's we call it in the. Science insectional permeability as Joanna mentioned.
