I should add an update here in case it is useful to someone.
I've had a fairly clean and successful diet for decades. My bones were always extremely strong - at least they felt that way to me. Never injuries without very rapid and sometimes extraordinary healing. Never did my bones give me an issue.
A few years ago I added dairy to my diet. It was one of the few changes. The grass-fed raw milk that I made into cheese, whey and butter never made me feel bad - only good - at least on a temporary basis. I would go off of it for weeks sometimes - but over the course of a few years it became a general part of my diet - not in excess - just a nice addition.
I not too long ago (in the scheme of things) realized that my bones had become a problem. In exercise my bones would be the first to give out. I was always able to get up and do lots of intense physical labor without any exercise in-between - but I got to the point where I was feeling pain upon exertion in my bones and would get injured.
Tyler posted an article about dairy and I realize that I might have done long-term damage to my mineral balance and hence to my bones even though when I ate dairy I felt good from it generally. So, I gave up dairy. My bones have been getting stronger and stronger from the time I gave it up.
Because my diet had been so clean and basically consistent for decades I was able to evaluate the dairy for me in a way that perhaps few can. It was a clean experiment. I've never had a dairy allergy and when I got into raw grass-fed dairy I thought it was God's gift and I REALLY miss it in terms of taste and variety to my diet - so it's not like I have anything against dairy - actually - I was such a big dairy fan there for those years and still think it has it's place. I just wanted to make sure that people here know what my experience was and that my opinions on dairy have changed.
I am very grateful to this forum for showing me that dairy for me had long-term effects on me that I was not aware of and that in fact, staying away from dairy was and is important for me.
