A new study to be published in PLOS One
suggests that consuming soy protein may benefit weight management, liver and colon health, which are of specific concern for obese individuals. The trial was conducted in mice and aimed to explore the effects of dietary soy protein, or casein, on serum hormones implicated in colon health and body fat deposition. The authors had previously shown that inclusion of soy protein in the diets of mice resulted in lower body fat and promoted normal cell growth in the colons of rats. Results of this study showed that mice fed the soy protein versus casein based diets had significantly reduced body fat, blood insulin levels, fat cell size and expression of genes associated with abnormal colonic cell growth. There was also a trend for lower fat accumulation in the livers of normal mice fed a high fat diet containing soy protein compared to a high fat diet containing casein.
“We are excited by these findings as they continue to support and extend the observations of other researchers that have shown a benefit of soy protein in maintaining healthy fat levels in the livers of other animal models,” commented Elaine Krul, science fellow and lead, Nutrition Discovery at Solae LLC, St. Louis, MO.
