> you have things like wheat/grain proteins which are some ~20% bioavailable
Do you have a source for this claim? It seems very low. It seems to be different ways of measuring, but one source [1] claims 65% postprandial retention (not 100% sure what it means). Another claims "The real ileal digestibility of dietary wheat nitrogen amounted to 90.3 ± 4.3%." [2]
EDIT: So the 20% number somehow account for the low lysine content (seems strange to call that bioavailability, but I'm not a biologist)
