That makes so much sense -- about the leaky gut. And yes, kefir. I have dairy goats and am going to use the raw milk for making raw butter, raw cream, and raw cheese -- my first set of kids just weaned, so now I have milk. The last time I tried kefir, I had autoimmune/histamine issues with it, though it is possible it's because I was at the time feeding GMO grain to my goats --- which I no longer do. I got rid of the goats because I believed it was the dairy itself making me sick. Then a couple of years later I bought some raw goat milk from a woman who fed her goats only pasture, non-GMO hay, and lots of veggies and leftovers from their garden. I drank her milk all summer and experienced excellent results. So then I got some baby goats, and started all over again. I made my first batch of raw cheese yesterday, and will get some kefir grains next time I go to town for supplies. Fingers crossed!
