Renal failure can be caused by dozens of pharmaceutical products that are available OTC and for which no medical supervision (yet alone strict medical supervision) is practised.I did provide the link. You didn't read it, or at best just skimmed it. Also read the references.
The article clearly stated that renal failure was a risk and that this diet needed to be used only for a limited time and under strict medical supervision.
If you are not interested, have made up your mind, and will ignore anything that the experts say : fine, but don't try to act all high and mighty and come up with expansionist statements.
Just do what the others do. Blissful ignorance.
I am all for wanting proper information and scientifically premised warnings to be issued but the hyperbole as to danger is simply nonsense.
