Table 1.

PDCAAS and DIAAS values. Limited AA calculated with an AA reference ratio according to different proteins sources.

Protein source	PDCAAS	DIAAS	Limiting AA
Whey protein isolated	1.00	1.09	His
Whey protein concentrate	1.00	1.18	Met+Cys
Soy protein concentrate (mean of two sources)	0.989	0.902	Met+Cys
Pea protein concentrate	0.893	0.822	Met+Cys
Rice protein concentrate	0.419	0.371	Lys
Cooked kidney beans	0.648	0.588	Met+Cys
Cooked rice	0.616	0.595	Lys

PDCAAS: Protein Digestibility-Corrected Amino Acid Score; DIAAS: Digestibile Indispensabile Amino Acid Score; AA: amino-acids
