Was wondering if anybody had a link to some medical articles on protein absorption. I know there have been a few threads on this, and I've read that one can only absorb ~30gms a sitting. I would think not everybody could be categorized into one category (120lb female vs 220lb BBer), however I was looking for studies.

I'm taking a Human Nutrition class and they are putting the RDA of protein at around 65gms, and an upper level of around 130. I'm sure most of you including myself get at least double that. I'm all natural so my intake would be different from somebody who's on AAS, but I'm wondering why people would consume so much in one sitting if you can only absorb ~30-40. Anyway, studies on this would be appreciated.
