View Full Version : Dangerous protein amounts?

Ok so I am a geek and I was reading a book by M.D.'s, the ones who did Clinton's triple/quadruple? bypass surgery.

In the book and I quote "Ultra high protein diets can accelerate bone loss. Large amounts of protein eaten every day-in amont of 140 grams a day- are believed to be threatening to your bones because the extra protein can cause your body to excrete calcium rather than absorb it."

Has anyone ever heard of this? They dont site a source here in the book so I was just wondering. I am trying to figure out if it is a good idea to take more calcium than my multivitamin has in it? They say caffiene does the same thing too which is like a double whammy...

Thanks in advance for thoughts on this, just wanna make sure when I am old the ol' bones hold up.

Well, I'm old, I take 1000 mg caffeine daily, and I usually consume about 200g of protein every day.

Probably gonna hear my spine shatter next time I squat 185 ...

Unless there were multiple studies backing up this claim, I'd say opinions are like *******s dude.

It's funny, last night I had a bone scan and found out I may have osteopenia. I was shocked. I'm following up to see if I really have an issue with bone density, and what I can do about it. Whether this has anything to do with a high protein diet is near impossible to say. There are a lot of other factors. I'm lactose intolerant for one, which could definitely have contributed to a calcium deficiency throughout my life. This is something I'll do some research on and see if there is any foundation.

There were some studies done with protein that showed an increase in protein causing calcium to drop from the body into the urine...which would lead to an eventual problem with bone density later on, unless of course adequate calcium was supplied to the body. But that's about the only study I read about that had any correlation with bone density and increased protein intake. Also, at the end of your 20s is when the door closes for you to have maximum bone density. After that, no matter what you do your bone density slowly worsens over time. Weightlifting and such keeps the bones strong for longer, though.

I am lactose intolerant as well, that is why I was so curious. I dont want osteoporosis when I get older. Its so common in older women and the only way to prevent it is at my age now. No study was referenced, which makes me leary, it was just nation renowned(?) docs saying this. I am in training this week at work so no computer all week, so I couldnt research it. Of course when I get home I go lift :).

Even if it is true, the amount of milk most of us drink probably would offset it. There's no way the body would ever excrete 100% of the calcium you take in. You would just die. There would be no bone density deficiency to worry about then.

I don't think that it is safe to assume that "most of us" drink a large enough "amount of milk" to not worry about osteoporosis. Osteoporosis is very common. My arguement is that exercise and a diet that includes appropriate amounts of calcium will have a much greater preventative effect on osteoporosis than avoiding protein and caffeine will.

Don't forget the positive effects of resistance training on bone health... those of us eating 250g of protein a day are also lifting weights.

Is 353grams of protein too much for a 160lbs. person?

goodnick yes probably...you should take in 1 to 1.5 grams of protein per lb of body weight

and does that study take into account how drinking soda pop ABSOLUTELY causes the body to leech calcium from teeth and bones to balance blood-calcium levels to counteract all the phosphorus in the bloodstream (from phosphoric acid in soda)?

yet another reason that soda pop is EVIL. if it doesn't rot your teeth, it'll weaken them from the inside out, along with your bones...because if your blood-calcium levels get off balance...you die. A smidge off and you get irregular heartrate...a smidge more off and the heart stops beating.

malkore yes it mentions soda... but i dont drink that so no worry there for me. :)

scarz:i drink the way to expensive lactaid milk and take some lactaid when I want to eat other dairy but honestly I just usually avoid it...

pruneman: I don't plan on not eating my 1.5 grams of protein or taking my energy saving caffiene I am just curious if I should be uping my daily calcium dose due to the protein intake? The lifting will help the bone health only if I have enough calcium to give the bone when it wants it... come to think of it i don't know if there is a thing as too much calcium... or bad amount either

A trainer told me once the more you lift the less protein you need. So if you eat to much protein it will acutally be counter productive.
That's the only thing I've heard on "too much protein".

The more you lift, the LESS protein you need?

Because muscles are made out of air?

No, they way he put it is like "you absorb it better" or something. I dunno, just what I heard.

Oh, I'm not really surprised at anything I hear from PTs anymore. Hell, I still see a lot of 'em putting people on high reps for cutting.

What do they TEACH these people? I KNOW there ARE some good ones, but, um, not many.

Yea.. the guy was kind of young (and short).

I'll be a good one Built.

Maybe he was referring to how not much gets absorbed if you take it all at once?

Built

Good boy, Nick.

I doubt he'd think you'd get LESS efficient at absorbing protein if you lift. I think he was just stupid.

Even then it's a stupid thing to say, and obviously screwed up at least on persons outlook on protein intake.

Why do people call them PTs!? PT=Physical Therapist, not personal trainer

You say tomato.

If this was some type of medical related board I could understand but we all understand the abbreviations.
