Consuming a blend of proteins (isolated soy protein, whey protein and casein) may have advantages for sports performance and provide nutritional advantages over consuming just one type of protein, according to a review by Dr. Greg Paul, global director of sports nutrition, Solae, LL, which was published in a supplement accompanying the Journal of the American College of Nutrition.
The review is titled “The Rationale for Consuming Protein Blends in Sports Nutrition.” Dr. Paul said of the study, “My review proves not only the importance of protein, but also potential benefits of combining different proteins, particularly to help promote recovery after exercise activity.”
According to the U.S. Food and Drug Administration (FDA) labeling guidelines, isolated soy protein, whey protein and casein are all nutritionally complete proteins. However, all three proteins differ in digestion rates, potentially creating a “timed-release” effect that could prolong the time that absorbed amino acids are delivered to muscle resulting in faster recovery. Additionally, comparative studies between isolated soy protein and whey protein show similar increases in lean body mass whereas whey protein may have an advantage over casein.
