Compared to Casein, Soy May Protect Muscle from Protein Loss

TOKUSHIMA, Japan--Researchers from the University of Tokushima and Shikoku University found that soy protein may prevent protein loss in muscle following exercise better than casein protein, a finding published in Junes Nutrition (18, 6:490-5, 2002) (

In a laboratory animal model, rats were fed either a 20-percent diet of soy protein or 20-percent diet of casein protein. The animals were then led through a treadmill running exercise in which the rats on the 20-percent soy protein diet appeared to have fewer physiological activities that broke down muscle compared to those on the casein diet. The studys authors concluded that soy protein may prevent exercise-induced protein degradation in skeletal muscle.
