Listening to this Ray Peat Interviewon dairy brought up a question for me. I use to drink milk and it caused me no evident problems. I didn't get mucous or anything. Then in the early 80s, a campaign started against dairy. I swallowed the meme. Later on, the "truth" of the anti-dairy campaign was "verified". I would get somewhat stopped up when I tried to drink milk AND I would get the "runs". I am wondering if, as Peat suggests, I just need to be exposed to it again and that my enzymes will adjust.
Mind you, I am not saying that the above is true for all people. However, it seems to be in my case. So, my question is, did you start out sensitive to dairy or is it something you acquired by halting the use of dairy?
