Thank you. I have not checked all the research about that, that's why, thank you for that comment.
However, I tend to trust mu doctor, since she has IBS (she has it much worse than me, btw, I'm just a "mild case" compared to her) and is up to speed with the clinical literature. If she sais that FF dairy should be OK (and she did all my bloodwork, I am not lactose intollerant, no protein/enzyme imbalances and so on), I believe her.
I am just trying to raise some awareness that the EFI guidelines are not guidelines only concerning everything but dairy, but apply as GUIDELINES (not rigid rules) to dairy as well.
