"Your body can't absorb more than 30g of protein in 1 sitting"

So I've spent some time reading up on if there is a limit on how much protein (especially from shakes because real food sources take longer to digest) your body can absorb in 1 sitting. Most fitness experts suggest that anything past 30 grams, your kidneys won't absorb and it just goes straight into the bowl.

Does anyone here think there is any truth in this?

(I began looking into this, because I don't have much of an appetite yet, so I try to cram as much protein possible in each meal AKA more than 30)

I know there is a limit on how much your body will use in one sitting.  Not sure the exact number.  I was told at one point it was under 20 grams.  Truth is, it probably depends on how well you chew the food and how easily it is digested as well.  I know it should be scattered throughout the day, but sorry, I am unclear on the exact number of grams at one time.  Will watch this post to see what others have found. 

My doctor told us 35g. That's why do many shakes are formulated to come out at that number.

I think its a crock of hooey. But I do think there is probably more to it than that. I think if you drink a 30 gram protein shake and go and sit down to watch TV all day, then yes you probably are not going to absorb much of it. But if you are gunning down 50 grams of protein within the next hour you hit the gym for a weight lifting session then you are probably going to use it all and possible some more. I think what they talk about is a general rule. You are not getting much protein in your normal diet. 

The one rule I try to follow is 30 grams within 30 mins of waking up. But I routinely get more than 30 and I don't see any difference in my urine or feces so I don't think I am dumping it.

Yea, as there's no definite way to prove how much your body absorbs, & everyone's body functions differently - there are conflicting answers.

But supposedly when it comes to protein shakes (whey) your body absorbs 10g per hour

Bodybuilder have been debunking this for years. Remember most of them take in 200grams of protein when training.

Thanks for the link! :)   If I wasn't able to have more than 25 or 30 grams in one sitting there is no way I'd meet my protein requirements, as I have enough trouble as it is.

The funny thing is that most of the proponents of the "no more than 30g at once" rule were in the bodybuilding.com forums.

Well, your kidneys don't absorb your food---your intestines do. (*grin*) There probably is a limit, but I'm sure it varies from person to person.

After reading the article, I wonder what the digestibility is of those protein shots I see advertised.  The article mentioned the digestibility of meat at 97%. 

The shots are garbage for us post op folks. It is the nails,skin and hair of the pig.
