Actually, the real crime in this report is that it's scare mongering based on insufficient data and evidence.

Five people, and no control group is NOT research. This is merely an experiment. It's also worth noting that the five subjects did not restrict carbohydrate intake during the "experiment".

... increased protein intake leads to an excess build-up of nitrogen in the blood. "In the end, the nitrogen ends up at the kidney in the form of urea where it needs to be filtered out and excreted in the urine."

Indeed. This is what normal, healthy kidneys do. This is not an added stressor or something harmful to kidneys, this is exactly their role and function. To state that increasing the amount of urea increases workload on the kidneys and will therefore be damaging, is like saying exercise is harmful to the heart and lungs because it makes them work harder to take in oxygen and get rid of the excess carbon dioxide and lactate that builds up in the blood.  duh!!
Excessive protein CAN be stressful to kidneys that are already damaged and diseased.

Common sense. If the solution is so simple and obvious, then why the scare tactics and campaign against protein as if some sort of irreparable damage will ensue???
