A little tidbit I found
NUTRITION CORNER: How many grams of protein per meal?
Quote:
There is a prevailing belief that the body can only process 30 grams of protein at a sitting. I can't even begin to count the number of times that I've heard this "30 gram rule" cited by so-called fitness experts. The fact is, however, there's simply no science to back up the claim. To understand why, a little physiology is in order.
The digestion of protein takes place in the small intestine and is facilitated by various "enzymes" and "transporters". Protein is broken down into its constituent components, the amino acids, which are then taken up by the intestinal cells (called enterocytes). Enzymes speed up the breakdown and assimilation of protein, and transporters assist the amino acids in their passage through the intestinal cells and into the bloodstream. Both enzymes and transporters are very sensitive to the presence of amino acids. When protein intake is increased, the body increases the amount of protein enzymes and transporters in the intestines to accommodate increased protein consumption. Hence, increased protein consumption is met by increased protein absorption.
In final analysis, there is no magic amount as to how much protein can be consumed per meal. No evidence exists that 30 grams of protein, or any other amount for that matter, is an upper limit for protein intake. That said, a good case can be made for consuming smaller, more frequent protein meals throughout the day. Doing so ensures a steady stream of protein into the body, providing the nutrients needed for muscular development.
