So I say you just quit bodybuilding and pick up Badminton as a hobby, or you can have an 8 ounce hamburger post workout everyday
But make sure thats natural beef your getting because then it could be coming from cows that were raised "Unnaturally" and they were given hormones to make them weight more, and if they aren't free-range animals they get upset and make
sure when the farmers kill them they give off disease and sickness to everyone who eats them.
On a serious note though, I've heard about this debate several times and I think the whole thing is BS. I've personnally used whey protein for over 2 years and I've never experienced any "Kidney Deterioration" and I'm sure there are people on this board who have been using whey protein for over 10 years, and they are fine. Even though I hate to take stuff from Bodybuilding.com for the sake of this debate I will

Are High Protein Diets Safe? Dispelling The Myths.
By: Layne Norton
Ever since the day I first touched a weight, I've heard them, the myths surrounding weightlifting and bodybuilding. I'm sure you've heard some of them at one time or another as well. Everything from "weightlifting stunts your growth" to "lifting weights shrinks your penis" to "you know creatine is a steroid, right?"
While many myths are easy to write off as being ridiculous, the myths surrounding protein intake are more widespread. Many people have the impression that high protein diets are unhealthy. Kidney damage, liver damage, heart disease, osteoporosis and others have all been blamed, to some degree, on high protein intakes.
Even the American Heart Association's (AHA) Nutrition Committee stated in 2001 "Individuals who follow these (high protein) diets are at risk for... potential cardiac, renal, bone, and liver abnormalities." Unfortunately for the AHA, there is very little scientific validity to their claim, and much scientific evidence to the contrary.
Myth One
Kidneys
The kidneys are involved in nitrogen excretion, and thus it has been theorized by some that a high nitrogen intake (protein) may cause stress to the kidneys. Additionally, low protein diets have typically been recommended to people who suffer from renal disorders. To conclude that a high protein intake damages the kidney is very tenuous however.
A study examining bodybuilders with protein intakes of 2.8g/kg vs. well trained athletes with moderate protein intakes revealed no significant differences in kidney function between the groups.1 Additionally, a review of the scientific literature on protein intake and renal function concluded that "there is no reason to restrict protein in healthy individuals."
Furthermore, the review concluded that not only does a low protein intake not prevent the decline in renal function with age, it may actually be the major cause of the decline!2
