I've been trying to actually read the source material for all this "bio availability" scoring like DIAAS and I keep finding weird things. For example, for DIAAS they took current food production, averaged the total protein ratios, and assumes that's ideal protein ratio for humans. It makes me think they're overstating the score of things like whey because of the severe amounts of cheese people eat.

Do you have any source studies with test methodology described? I don't buy that humans should be devouring milk all day when dairy as a nutrition source is so wildly varied across the globe.
