 I know I sound like a broken record, but you have to read Good Calories Bad Calories. If you did, you wouldn't have posted that. Seriously.

Actually I still would have. What we have to keep in mind is that we all respond differently to different diets. As I posted in the past when I raced I lived on carbohydrates and was very healthy and full of energy. For example on one bicycle trip I had to go 300 miles in two days. So I did 200 miles the first day and the last 100 the second day with a full touring load on the bike. My average touring day on trips was 115-130 miles per day. That was all on carbohydrate sources, particularly pasta, rice and potatoes. I also did triathlons on a regular basis. But if I tried eating meat my energy would plummet after 3 days and I wold be lucky if I could run a few miles. Back on to the carbs and I was fine.

Protein is not always a good choice. It can be hard on the  liver, it raises uric acid levels that can cause gout and kidney disease for starters. It is also harder to digest and most proteins contain other substances that are not good such as hormones and antibiotics. In addition meat protein sources do not feed the flora, which we need for immunity, protection from pathogens, balancing the hormones, etc.

Regardless of what any book or website says we need a balanced diet. High protein is not good. High carbohydrate is not good, High fat is not good. What is good is a balanced diet providing some of each of these.  And with some people having certain conditions the balance may need to be altered. For example protein has to be limited in people with kidney failure.

As far as the claim about high protein raising cancer risk there is a basis for this. High protein raises insulin-like growth factor-1 (IGF-1), which in high levels can lead to cancer, bone disorders, joint disorders, etc. And protein sources include milk, which frequently contains recombinant bovine growth hormone (rBGH), given to cow's in order to increase milk supply. The problem is that rBGH increases IGF-1 even further. So the problems are not only the amount of protein ingested but also the sources of protein.  But again a balanced diet reduces these risks.

On the other hand though IGF-1 does not always increase cancer. IGF-1 is actually found in higher amounts when we are younger to promote cellular growth. But in a healthy individual its levels are still kept in check. But it declines with age for a good reason and stimulating higher levels of IGF-1 as we age is just asking for trouble if something goes wrong preventing its proper regulation.  It is like estrogen levels drop for a reason as a woman ages. So should they take Premarin to boost their estrogen as they age fighting the body's infinite wisdom that is saying lower the estrogen? Of course not because the body knowns better than we do. This also applies to the drops of IGF-1 as we age. It is not a good idea to increase this with high protein when the body is trying to lower it. 

As a final note I want to point out that the US has the highest kidney disease rate in the world. Much of this is because Americans consume way more protein than the body can utilize, which is only roughly 3 ounces a day or 90 grams. On top of that they do not drink enough water. Not coffee, not tea, not juice but actual water. This creates the perfect storm for kidney damage. Excess protein elevates uric acid levels.  Inadequate water intake prevents proper hydrolysis. This allows the undissolved glass sharp crystals of uric acid to pass through the kidneys shredding the kidney tissues in the process.
