- PDCAAS is a way to evaluate protein quality
- Scores range from 1 (highest) to 0 (lowest)
- Proteins that score 1 include whey, eggs, and soy
Think all protein is the same? Think again.
Some proteins are the Tom Brady of the nutrition game, while others are more like that kid who just showed up to play pick-up football at the park. That's where the PDCAAS comes in.
The PDCAAS stands for Protein Digestibility Corrected Amino Acid Score, and it's basically like a report card for proteins. It evaluates how well a protein provides our bodies with essential amino acids and gives it a score from 0 to 1, with 1 being the highest possible score. So, the higher the score, the better the protein.
Take whey or soy protein, for instance. It gets a 1.0 on the PDCAAS, which means it's a complete protein and has all the essential amino acids that our bodies need to perform at their best. Meanwhile, protein from wheat only gets a 0.42, which is like getting a C- on your report card. Not exactly a star performer.
Basically, the PDCAAS helps us pick out the all-star proteins from the benchwarmers. At Atlas, we use whey protein because it's one of the few proteins that land a perfect score. So, when choosing your proteins, make sure you choose wisely and go for the Tom Brady of the protein world!
