Ok so i've been hearing alot of stuff about how high protein diets are actually very harmful to your body. Ketoacidosis, putting extreme strain on the kidneys to filter out excess protein, blocking various functions of the body such as calcium absorption and bone growth. Even build of of toxins in the digestive track leading to cancer and tumors later on in life. This isn't just some small niche of people either, its nutritionists and scientist performing trials and test to look into this, and from what ive seen it all shows that high protein diets are bad for you really bad. Has anyone else been seeing or hearing about this? What do you guys know about this? Is that only for non-builders, and were safe because we use the protein? or are we all slowly poisoning ourselves?

keto acidosis is usually found in diabetics
also the reason why is due to muscle catabolism of BCAAs causing amonia to be filted through the kidny and causing harmful toxins in the body however in all these studies how much protein and how much water are the individuals taking>? in most protein studies i dont believe i see a water intake consistent of what we take in

thats is another thought i had about it. since we all take in excess water to feed our muscles and help with growth. wouldn't it also take the load of the kidneys by diluting the filtering process with the excess water?

It's a few years old now, but Berardi's article is still relevant. There is a bit more calcium loss, but overall it may actually be better in some other respects. To browse the literature, see http://scholar.google.ca/scholar?q=H...=r&as_ylo=2004

Yes, kidney/renal disease leading to failure can be a side effect of high protein diets for sustained periods. The majority of people believe they require much more protein than actually needed. For the most intense athletes they only require 1.5 - 2.2 g protein per kilogram of body weight.

I have heard about studies that showed how Casein protein could cause cancer and hw its bad. After hearing that I never took my bedtime ON Casein protein shake again.

If that's true then why do professional athletes eat carbohydrates? Why does anyone eat them?

So Im still seeing alot of conflicting ideas still, but the main idea im getting from this is:
-Athletes do need higher levels of protein to construct increased muscle and help boost body function and repair.
-Although higher levels are needed, its best not to over do it because too much excess can cause problems.
-After getting protein intake close to "optimization" levels, drinking added water and taking a multivitamin(to keep you system balanced and avoid the excess water flushing necessary nutrients out of your system), it should stave of any negative effects as the body will use most of the protein and any excess will by diluted by the water intake and preventing any damaging effects.
Did i get that all right?

Ok lets look at this practically. When your average person talks about high protein diets being bad for you they generally are speaking about people who do not perform an abundance of resistance training and often people who do not consume the amount of water condusive to the amount of protein they take in.
If your performing high amounts of strenuous exercise you obviously need more protein than the average Joe, and if your doing it to gain muscle mass even moreso. As you know protein is necessary for reparation of muscles during recovery. That is, as most of you know how muscle is built. If you are taking in increased amounts of protein then you will have to take in more water.
Yah you can do damage on high protein diets if it's more protein than you should be taking over an extended period. What is too much for Person A however may not be too much for Person B. Generally I think a lot of us do use a little too much. I myself am getting by on much less with very good results. Most would still consider my diet high at around 250-70 grams a day. I weigh 240 and am quite lean so that definitely is not that excessive. I believe it to be a healthy level for my lifestyle.
I think it is definitely think it is something each one of us should consider but don't get caught up in the hype about high protein is bad... it could be but not neccessarily.

Notice all the aging bodybuilders dying from kidney failure? neither do I.
Lean/Clean Protein + adequate water you will never have issues.
I take in at least 240 grams of protein and minimum of 150oz water per day for decade, I get a full checkup (including kindey/liver/thyroid/etc..) once a year. Everything according to Doc is perfect.

i saw a study linking too much protein consumptions to health problems a while back...i believe it was 5g/lb of body weight...so a 200 lb bodybuilder would have to eat 1000g of protein a day...again in excess everything is dangerous. alot of idiots took this and misconstrued the information..
