Please help! I believe melamine and cyanuric acids in our US food supply have been forming crystals in our tubules.I believe this is part of the cause of the recent increase in kidney stones in the US.The damage to the tubules decreases the ability for the kidneys to absorb proteins and filter out salts effectively.Please help with studies and bringing awareness to this deadly and serious problem in the US and the world.
