Abstract
This study examined the effects of soybean beta -conglycinin, from which ph ytate was mostly removed, on the plasma lipids in young and adult rats. Mal e Wistar young (6 week-old) and adult (21 week-old) rats were fed high chol esterol diets containing 20% casein, soy protein isolate (SPI), or soybean beta -conglycinin for 10 days. In young rats, although the food intake of t he beta -conglycinin group was higher than those of the casein and SPI grou ps, the weight gain was significantly lower than those of the other groups. However, in adult rats, the weight gain was not different among the groups . In young and adult rats, relative liver weights of SPI and beta -conglyci nin groups were significantly lower than that of the casein group, and the degree of the reduction was more marked in the beta -conglycinin group than in the SPI group. In young rats, the plasma triglyceride level was signifi cantly lower in the SPI and beta -conglycinin groups than that in the casei n group. In addition, the plasma triglyceride level of the beta -conglycini n group was significantly lower than that of the SPI group. Plasma total ch olesterol levels of the SPI and beta -conglycinin groups were significantly lower than that of the casein group. However, there was little difference in the lowering effect between SPI and beta -conglycinin. These results ind icate that soybean beta -conglycinin may have lowering functions not only o n plasma total cholesterol level, but also on plasma triglyceride level.
