I don't know this for a fact by any means, but I have always thought that kidney damage wasn't necessarily caused by the protein itself, but other byproducts of meat, and also a lack of carbs.
When you don't eat enough carbs, you
body will try to burn protein as an
energy source, which makes byproducts that are hard on your kidneys. I have always assumed that if you eat enough complex carbs to allow your
body to fuel off of, that protein won't be burned as an
energy source, and therefore kidney damage is at least minimized.
Also, alot of people who eat alot of protein will eat alot of meat, and the byproducts of the meat, including the animal's lactic acid, will be absorbed into the bloodstream, putting a big load on the kidneys. Supposedly these byproducts can even be absorbed through the colon walls and get back into your bloodstream.
Both of these issues were discussed in the Mountain Bike Training Bible. So, this is why I've always assumed that excess amino acids ALONE isn't necessarily harmful, just not needed. I think it's the other extra baggate that does damage.
