Dietary nucleotides and nucleosides obtained from meat, collagen, and organs are necessary for repair and can increase mucosal protein, DNA concentration, and villi length in the small intestine.

“do you think we should be getting nucleotides and nucleosides from meat for repair yes yes from collagen from meat from organs yes most dietary nucleotides are absorbed as nucleosides subsequently rephosphorylated in the enterocyte that's how they're absorbed dietary nucleotides may increase the formation of mucosal protein the concentration of dna and the length of the villi in the small intestine”
