I have this full 6 hours of this seminar (8 minute summary) and Mat Lalonde says the whole acid-base arguments that Cordain puts forth is bunk and Robb Wolf relies upon Mat's professional opinions.

We understand pretty clearly from the research on this stuff that--they had a great study. I know I've linked to it a couple of times. I think I did a blog post on it, related to increased protein intake in post-menopausal women improving bone mineral density. So at the end of the day, the questions that typically pop up related to this are around (1) bone mineral density and then (2) cancer which we'll get to in a second. But what we find is that when people increase their protein intake, you may in fact get some increased urine excretion of hydrogen ions in acid excretion, but we also see a bunch of other compensatory mechanisms hat make it just fine with regards to a bone mineral status and it may actually improve it, and that seems to be the stuff that we're seeing.
So looking at simply what we are peeing out is neglecting several other avenues on this acid-base piece, not the least of which is respiratory acid-base balance in the bicarbonate shuffling either into or out of the blood as acid-base buffer. So that's one piece."
Would I be putting a grain-feed cow on a fad diet if I took it out of the feedlot and put it on pasture eating the grass nature intended?
