i've heard a few times, and again today, that applying heat to whey will cancel out it's protein content. unfortunately i have never been able to uncover any studies.

to vary up my diet, i eat protein pancakes regularly - these are made from primarily from cottage cheese. i suppose if the above statement is true, then some protein content of regular cheese (mont jack, etc) is affected as well.

if protein is lost, what % of it is lost?
