Biology:Digestible Indispensable Amino Acid Score

From HandWiki
Short description: Protein quality method

Digestible Indispensable Amino Acid Score (DIAAS) is a protein quality method proposed in March 2013 by the Food and Agriculture Organization to replace the current protein ranking standard, the Protein Digestibility Corrected Amino Acid Score (PDCAAS).

The DIAAS accounts for amino acid digestibility at the end of the small intestine, providing a more accurate measure of the amounts of amino acids absorbed by the body and the protein's contribution to human amino acid and nitrogen requirements. This is in contrast to the PDCAAS, which is based on an estimate of digestibility over the total digestive tract. Values stated using this method generally overestimate the amount of amino acids absorbed.[1]

Reference pattern

Amino acid requirements were determined in two parts. The amino acid distribution of breast milk was used for the 0 to 6 month age range, and existing amino acid data was used for older ages after adjustment for digestibility. The reference amino acid requirements are presented below.[2]:29

Requirements by age (mg/g protein)
Amino acid 0 to 6 months 6 months to 3 years Over 3 years
Histidine 21 20 16
Isoleucine 55 32 30
Leucine 96 66 61
Lysine 69 57 48
Methionine + Cysteine (SAA) 33 27 23
Phenylalanine + Tyrosine (AAA) 94 52 41
Threonine 44 31 25
Tryptophan 17 8.5 6.6
Valine 55 43 40

Example values

The table shows the ratings of selected foods comparing PDCAAS to DIAAS.[3][4][5][6][7][8][9][10][11][12][13][14] The quality of various sources of protein depends on how it is processed, refined, stored, or cooked.[12][15][16] (preparation is unspecified for some values in the table, but does not necessarily differ in preparation from the foods where preparation is specified). A major difference between DIAAS and PDCAAS, is that PDCAAS is truncated at 100%, while DIAAS is not. Multiple protein sources can also be combined to increase DIAAS, which can be effective at raising the max DIAAS of plant-based diets.[13]
