I'm actually going to respond indirectly versus to direct questions in this one as I am asked this question rather frequently actually.
The prototypical route this one is asked is:
"I've heard that you can't absorb more than ___grams of protein per meal. Is this true?"
Fill in the blank with the number of the hour for whichever magazine or suggested expert the question-asker seems to be quoting.
There are so MANY variables that dictate the answer, however, and I suppose if it were that easy then it wouldn't tend to lead to so many myths, right? See - even if only a certain number is absorbed, the quotation fails to consider how many amino acids may be required at any one particular time. Also, protein turnover rates also differ for different people.
Further still, let's say you are "cutting" - if you consume too many grams (especially in a reduced-carbohydrate state), you could very well be supplying gluconeogenic pathways (opposite of your goal). On the contrary, if you are consuming too few, you could be placing yourself at a distinct disadvantage in "cutting" or "bulking" due to both caloric deprivation and/or protein turnover requirements to maintain a positive nitrogen balance.
It does NOT matter if you understand all the terms I referenced above! What is important is that you see the question is NOT remotely as easy as either your nutrition profressors, and/or magazine article writers, and/or "gurus" on the net will make it. In fact, quite far from it.
