Question

Which of the following are true regarding soy proteins

1. soy is a complete protein
2. soy contains ~85% lower EAA content than milk
3. soy is the highest quality protein available

Answer 1

Soy protein is a complete protein, but it does not have as high essential amino acid content as milk. Therefore, it is not the highest quality protein available.

Step-by-step explanation:

Soy protein is a complete protein as it contains all the essential amino acids required by the body. However, it does not have as high essential amino acid content as milk. Milk protein, such as whey protein, has a higher Essential Amino Acid (EAA) content compared to soy protein. Therefore, statement 1 is true, statement 2 is false, and statement 3 is false as well. Soy protein is a good source of protein, but it is not the highest quality protein available.
