Whey Protein, A High Quality Protein Source

 
   

Whey has the highest protein quality rating among protein sources.

Digestibility - Whey protein is very easy to digest. It has a Biological Value (BV) of 104. In comparison, egg has a BV of 100, casein a BV of 77, and soy protein a BV of 74.

Utilization by the body - It is also well-utilized by the body for fabricating protein in the body. The Net Protein Utilization (NPU) for whey is 94%, compared to 61% for soy, for example.

Essential Amino Acids (EAA's)* - For those that familiar with the amino acid score, whey protein has a score of 102.** This means that whey protein provides amount of essential amino acids recommended*** per each gram of protein consumed. Another measure of EEA's in protein is the Protein Digestibility Corrected Amino Acid Score (PDCAAS). Both whey and soy protein have a score of 1.0

*Essential amino acids are amino acids that the body cannot produce itself, and thus must be obtained from food.
**A amino acid score of 100 indicates a protein that is complete, or a high-quality protein. A score less than 100 indicates a less complete protein.
***The amino acid score is based on EAA intake recommended by the Food and Agricultural Organization (FAO) of the UN.
