New study finds rice protein on par with whey

Double-blind study showed for the first time that plant-based rice protein has identical benefits to dairy-based whey protein for muscle growth and repair. 

The findings of a double-blind study showed for the first time that plant-based rice protein has identical benefits to dairy-based whey protein. The study used Growing Naturals' Organic Rice Protein made with Axiom Foods’ Oryzatein®, with a controlled population of bodybuilders and measured how they built muscle and experienced rates of repair and soreness. The study was published by the Nutrition Journal (June 19, 2013) and acknowledged by sports nutrition experts at the International Society of Sports Nutrition's 10th Annual Conference (June 14 to 15, 2013) and the Nutrition and Exercise Summit (July 10 to 13, 2013). Oryzatein was chosen for the study for its unique qualities, foremost being the hexane-free fractioning process used to isolate protein from whole grain brown rice. The paper of the study in the Nutrition Journal was so well received, it was awarded the status of number-one most "highly accessed."

"Previously, studies have shown that animal-derived protein had a different effect on muscle growth than plant-based protein such as soy," said Dr. Jaeger. "This has changed. We found that rice protein isolate administration post–resistance exercise decreases fat mass and increases lean body mass, muscle hypertrophy, power and strength comparable to whey protein isolate."

Dr. Jaeger and his coauthor, Dr. Jacob Wilson (University of Tampa, Department of Health Sciences and Human Performance), used 24 healthy, college-aged, resistance-trained participants who consumed 48 grams of rice or whey protein isolate immediately following training for eight weeks. 

David Janow, CEO, Axiom Foods Inc., creator of Oryzatein, said. "Whey protein has been the gold standard of the fitness industry, but intolerance to lactose affects nearly 70 percent of the world's population; as such this study will make a huge impact."
