Research Abstract

Soy protein isolate (SPI) is known to improve insulin resistance. Therefore, we measured parameters of whole body glucose metabolism in mice fed with high fat (HF) diet containing casein or SPI as main protein source for 4 weeks. Between mice fed with casein-HF diet and with SPI-HF diet, there is no difference in body weight, blood glucose levels, and plasma insulin levels. At 4 weeks after the initiation of HF feeding, we performed glucose tolerance test to evaluate whole body glucose tolerance between these two group and found no difference of glucose tolerance in these two groups. These findings suggested thatSPI has little effect to improve insulin resistance under the condition of 4 week HF feeding.
