I don’t know but I have heard that it is possible to reverse dairy intolerance. I was off dairy for years and am now trying to reincorporate it, just a little each day. I take lactase enzymes and drink a little plain kefir each day. Some things I tolerate well, and others I don’t, and it’s often a surprise which is which, so this is all a big experiment. BTW, unfermented soy is estrogenic and can kill your libido, so everyone should avoid it anyway. Good luck!
