We're talking about a paper that just came out at the end of 2023 and was published a few weeks ago, looking specifically at protein digestion. Hang on, buddy. Come here. Sorry about that. We're going to talk about protein digestion and the upper limits of what we think can happen with protein digestion. So we're going to talk about current protein recommendations based on the current body of research. We're going to talk about what this paper found and the conclusions it drew that may change those protein recommendations. And then we're going to talk about barriers to this research.

CURRENT PROTEIN CONSUMPTION RECOMMENDATIONS
So the paper we're referencing today, the title is the anabolic response to protein ingestion during recovery from exercise has no upper limit in magnitude and duration in humans. was a paper published in December 2023 by Tromelin and colleagues, pardon my sick son coughing, and the journal title is Cell Reports in Medicine. So that's the paper we're referencing. Current protein recommendations quite old and they typically recommend and advocate that humans can't digest or otherwise synthesize protein in amounts above about 20 to 25 grams of protein per hour and If you're like me, you were sitting in a lecture in undergrad maybe 20 years ago and you heard that based on literature from the 90s and the early 2000s and you thought, hmm, that seems really specific and also really impractical given how much protein we're recommending that people eat. How can somebody possibly only synthesize and utilize 20 to 25 grams per hour. That would mean an individual, especially a larger, more muscular individual, would basically need to be always eating protein, right? A lot of these studies look specifically at whey protein, a faster digesting version of protein. Whey protein is essentially the watery porti
