The Claim
The protein digestible indispensable amino acid score (PDCAAS) should be replaced by the digestible indispensable amino acid score (DIAAS) because evaluating proteins based on their digestible indispensable amino acid content, with each amino acid treated as an individual nutrient, provides a more accurate reflection of human nutritional needs.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Proteins should be rated using the DIAAS method instead of PDCAAS because DIAAS measures how well the body can absorb each essential amino acid individually, leading to a more accurate assessment of nutritional value for humans.
See the scientific wording
Proteins should be evaluated based on their digestible indispensable amino acid content, with each amino acid treated as an individual nutrient, and the protein digestibility corrected amino acid score (PDCAAS) should be replaced by the digestible indispensable amino acid score (DIAAS) to better reflect human nutritional needs.
When you eat protein, your body breaks it down into individual amino acids, and how many of those essential amino acids your intestines can absorb determines how well the protein supports your body's needs. Some proteins lose more amino acids during digestion, so measuring what actually gets absorbed gives a clearer picture of their nutritional value than older methods.
What the research says
1 studyScientists say we should measure how well our bodies can absorb each essential amino acid from food, instead of using the old method, because the new method (DIAAS) gives a more accurate picture of which proteins are best for our health.
