Is it right that the body can only digest 30g of protein in each meal?

I need a professional expert to answer me :
Is it right that the body can only digest 30g of protein in each meal?
So, if you take 60g the body will only use 30g and get rid of the rest.
I mean for body builders ...

no that is INCORRECT

It is Parroted Info...

**bigslick7878** · 12-13-2010, 05:40 PM

Uhhh...no.

There are "rumored" numbers out there of around 80grams but I have not seen any science to back it up.

But it is safe to say 30 is not even close.

Agreed with the above. I don't know if there is a definitive answer as to how much the body can handle in one sitting, but I think it can be definitively concluded that 30g is not that number. Most people I know are doing 50g PWO... you think by now they'd have been corrected if there were any truth to that.

Thank you very much guys.

i think 80 or something might be accurate for normal size people but for larger people such as myself it is probably around 130-140.. There is science behind it.. as Your body can only convert so much at such a rate to building/maintaining muscle and the rest would be broken down and used for energy instead.. but it is definitly not at 30g.. it is something ridiculous like anything over 500g of meat in one sitting..

Or stored as bodyfat. Unlikely but possible, and worth mentioning IMO.

100% of the protein you eat gets digested unless your body is not functioning properly

There has never really been a consensus in the scientific literature about how much protein the body can absorb in one sitting. Evolutionarily speaking, it would make no sense for the body to not be able to fully digest and assimilate all the protein that is consumed in a sitting. The only limiting factor would be the physical amount of food stuff a person could eat.

I was waiting for you to chime in. I almost posted the link in your thread haha. I decided to just respond with a smart ass answer that helps nobody instead...

The body definitely "digests" everything, but how much you can absorb for beneficial purposes in one sitting is unanswered. Its gotta dependent on the person though.

I would agree,

Just for sake of argument given ideal physiological conditions. Other food stuffs can effect digestion and absorption. There are so so many variables that my only recommendation would be to get between 1.2 to 1.8 grams of protein per lbs of body weight. Other than that, no one really knows I dont believe.

**Twist** · 12-13-2010, 11:37 PM

I would think that from a scientific standpoint you would say that 1.2 is overkill... Practical application may be different but that could be because of all the variables such as added calories and nutrients etc.. I have yet to read anything about protein Reabsorption(is that what you called it?)

**Twist** · 12-13-2010, 11:47 PM

Also what about kidney damage related to protein intake? My take on it is that you have to be eating insanely large amounts of protein, 85% of calories has to come from protein, and a predisposition to kidney problems will help it along.

Yeah your right, I meant to say per kilogram body weight. As of 2008, the NSCA recommends that a resistance training athletes consume between 1.5-2.0 grams of protein per kilogram of body weight. The broad range is because of the lack of general consensus in the literature about what exactly is the right amount.

I have never read any conclusive studies that have shown a link between high protein intake and kidney disease. Certainly those that have kidney problems may not want to eat 5 pounds of meat a day.

Thank you for the link!

I have a client who developed kidney disease because she thought she should only eat meat because she was getting fat and so she avoided carbs... She said she would eat a pound of meat at every meal. She said something along the lines of, "It was so easy to just eat 1 or 2 pounds of drumsticks you know?" I replied, "no, not really."
