The Study
Digestibility Issues of Vegetable versus Animal Proteins: Protein and Amino Acid Requirements—Functional Aspects
This isn't a real study with experiments or data — it's just a scientist saying what they think should be done. It's like saying 'I think we should use a new ruler to measure things' without showing any measurements. You can't prove anything from it.
Analysis score
Maximum 0 for a editorial/opinion.
Where the score came from
The study says even though tofu has all the good amino acids your body needs, your body can't use them as well as it can from eggs or meat.

Key takeaways
Summary
Based on the study abstract and findings.
- 1This matters because how well your body can use protein affects muscle building and overall health, especially for people relying on plant-based diets.
- 2Tofu has better amino acid mix than most plants but lower absorption than animal proteins; PDCAAS should be replaced by DIAAS.

Tofu contains all essential amino acids in better proportions than most plant proteins, but the body absorbs fewer of those amino acids from tofu than from eggs, meat, or dairy.
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.
