According to the North Carolina Egg Association, the Protein Efficiency Ratio (PER) of eggs is measured at 3.8, a number that outscores other proteins like beef at 2.9 and peas at 1.4. A food with a higher PER value indicates a more efficient protein source for supporting growth. This article explains why the Protein Efficiency Ratio is important for protein evaluation and which food takes the top spot.

Protein quality is not uniform across all food sources, with factors like amino acid profile and digestibility determining its value. A high-quality protein provides the essential amino acids needed by the human body to support growth and repair. This guide explores the scientific methods used to answer the question: **How do you measure protein quality?**

Over 700 million people globally were undernourished in 2023, partly due to low-quality protein sources in their diets. To determine a food's nutritional value, understanding **what is the best indicator for protein quality?** is crucial, as it goes beyond simply counting grams of protein.
