  Whey Protein
Normally supplementing a diet with extra protein was only for bodybuilding and powerlifting. Creating new muscle requires plenty of whole food protein or quality protein supplementation with a protein exhibiting a complete amino acid profile. Today, however, as consumers have begun giving credence to scientific data indicating the importance of quality protein in the diet, the marketplace for all proteins is expanding. Soy, milk, casein and rice protein have defined roles in the market, especially since consumers with food allergies and other health concerns are aware of the potential health benefits of protein.
“Protein is certainly an essential part of any healthy, active lifestyle, but you’re starting to see protein move into different arenas,” said Scott Steil of Humanetics Corp. Protein is increasingly associated with satiety, weight loss and sustained energy because it digests slowly in the human body and aids in controlling insulin fluctuations. Health-conscious consumers are taking note, and the market is diversifying. As sales of functional foods topped $25 billion in 2006 and should gross $39 billion by 2011—demand for protein of all shapes and sizes is high.
Milk, Whey & Casein
Milk proteins haven’t ruled the protein supplement market for over a decade by chance. When whey protein came to be associated with weight lifters, early manufacturers developed keen marketing strategies to create markets outside of muscle building and exercise recovery. The adage about milk doing a body good also benefited marketing efforts for isolated milk proteins. When the health benefits of protein began circulating in media outlets besides muscle mags, manufacturers looking to fortify existing products with protein naturally defaulted to whey and casein.
Dairy proteins have plenty of health benefits. A recent study on milk basic protein (MBP) showed it effectively increased bone mineral density (BMD) in young women, “primarily through the promotion of bone formation and inhibition of bone absorption.”1 Milk protein (casein) also “significantly reduced iron-induced lipid peroxidation”, and improved antioxidant status in athletes taking iron-rich sports supplements.2 Further, postprandial muscle protein synthesis was significantly improved in rats fed meals containing leucine-rich [whey] proteins.3 In the study, 60 rats received experimental meals with differing leucine concentrations. Muscle protein synthesis was then determined in vivo in the postprandial state at the end of the 30-day nutritional period. Results indicated leucine-rich proteins were efficient in improving muscle protein synthesis in old rats, suggesting whey proteins could possibly be efficient in preventing sarcopenia in elderly humans. Milk peptides have also been shown to have “antihypertensive effects in animal and clinical studies”, as well as “mechanisms to lower blood pressure such as opioid-like activities and mineral-binding and antithrombotic properties”, according to one research review.
