Are the Animals Taking Over the Protein Market?
Exercisers around the United States are constantly shopping for a quality source of protein to use post workout. What they usually grab is a tub of their favorite flavor of whey protein from a manufacturer they trust. Whey has been used for a very long time, giving the consumer the protein requirements needed to help pack on lean muscle. But, is someone new coming to the protein market?
A recent study is showing animal sources in the protein market might be just as beneficial, if not better.
A new double-blind study published in the Journal of the International Society of Sports Nutrition is showing that protein found in beef and chicken sources are just as effective at increasing lean body mass than the dairy version (whey) everyone is used to using. Researchers at the University of Tampa had 41 subjects (comprised of males and females aged between 18 and 30) complete an 8-week resistance training protocol where they were given 48g (2 servings of 24g each) a day of beef protein, chicken protein, whey protein, or maltodextrin. At the end of the study, the beef group gained 3.5 kg of lean mass; the chicken group gained 2.9 kg of lean mass; and the whey group gained 3.3 kg of lean mass. They also noted that there was a significant reduction in fat mass in the groups that were using the protein sources versus the maltodextrin. The beef group lost 2.7 kg; the chicken group lost 2.1 kg; and the whey group lost 1.4 kg. Oddly enough, while the maltodextrin group didn’t yield any lean mass gains, after the 8-weeks, the maltodextrin group actually lost 2.3 kg of fat mass.
As we know, the amino acid profiles are different in all the sources mentioned above. However, the study concluded that using beef or chicken as a post-workout protein source can be just as effective as using whey. So, will this create a demand in the protein market? The researchers mentioned that this is great news for those following the paleo diet and lifestyle.
