If I may nitpick:
- Human amino acid requirements vary with age, physical condition, and physiological state. PDCAAS and DIAAS use a young child as reference pattern.
- Amino acid proportion also varies across animal foods: eggs closely match the child pattern, while beef is slightly lower in tryptophan.[0]
- Some plant proteins are considered complete above scoring systems: soy, quinoa, buckwheat, amaranth, hemp, chia, and potato protein, though potatoes themselves are low in protein/carb.
