Abstract
Polyamines are important constituents of all mammalian cells. We previously found that polyamines in soy yogurt, a mixture of fermented soymilk and okara, absorbed easily in the small intestine of growing rats, but the polyamine level in plasma scarcely increased. The level of polyamine in the body tends to decrease with age. In the present study, we investigated changes in polyamine levels in the intestines and plasma of adult rats to clarify the effect of soy yogurt in supplying polyamine to the plasma in adult rats. The polyamine levels in the intestine and plasma of adult rats increased significantly after ingestion of soy yogurt. It was found that soy yogurt is useful for the recovery of polyamine in adult rats.
