Doggiemama: I also tested negative to milk intolerance, but I have since concluded for myself that I have an intolerance nevertherless. I always react strongly to dairy; get swollen (water retention in the body) and also get aches and pains in joints and muscles. So it is obvious that there is inflammation in the body provoked by dairy. Taking kefir (made with milk) for example did not go well at all. I got extremely bloated.
But maybe you are right it might be a leaky gut reaction? I have a leaky gut too. And if it is then here’s hoping that one day when the gut is healed dairy will no longer be a problem.
