Absence of post-prandial gut anabolism after intake of a low quality protein meal

In the post-prandial phase after intake of a low protein quality meal, net anabolism in the healthy intestine is absent. It is likely that the intestine responds with a net breakdown of endogenous (labile) proteins to secure amino acid availability for the body. Addition of the first limiting essential amino acid to this meal improved protein anabolism in the intestine. Protein quality of a meal is related to the anabolic response of the intestine during the meal.
