Protein quality

Protein quality is determined by amino acid composition and digestibility.

High-quality proteins contain all essential amino acids.

Animal-based proteins and some plant-based proteins have high digestibility.

Protein Digestibility Corrected Amino Acid Score (PDCAAS) evaluates protein quality, considering composition and digestibility.

A score of 1.0 indicates a complete, digestible protein.

Biological Value (BV) and Net Protein Utilization (NPU) assess protein quality.

Animal-based proteins score higher due to complete amino acid profiles.

Incorporating diverse protein sources ensures meeting protein needs.

Understanding protein quality informs our choices for optimal nutrition and well-being.

Selecting varied protein sources optimizes intake, supporting growth, repair, and maintenance of body tissues.
