Influence on serum element and defecation improvement by administration of young rice plant dry powder

Abstract

We manufactured dried young rice plant powder (YR) and analyzed the chemical composition and pesticide. The effect of administration of YR on clinical laboratory data was studied. YR contained 56% dietary fiber and 11% minerals and no pesticide. Three sticks of YR (1.75 g/stick) were administered to ten healthy adult every day for 12 weeks. No adverse effects to glucose metabolism, renal function, hepatic function and an electrolyte and no adverse events, such as induction of diarrhea or other serious problems were observed in the clinical laboratory data. To study the safety of excess intake of YR, six sticks were administered to six healthy adult. There were no adverse events too. Two or/and three sticks YR were given to 19 subjects for two weeks. The subjects filled out a questionnaire about the defecation frequency and fecal characteristics. In 10 subjects whose defecations was four or less than four days a week, the defecation frequency was increased significantly by two sticks of YR administration. The defecation frequency and quantity were increased significantly and improvement of fecal shape was observed by three sticks of YR administration. In 9 subjects whose defecations was more than four days a week, the defecation frequency and fecal characteristics didn't changed. There were no change on the number of fecal Bifidobacterium, total microflora, lecithinase positive Clostridium and pH. These results show that the intake of 5.3 g YR containing 3 g of dietary fiber improves the defecation frequency and the fecal characteristics, There was no adverse events by YR intake.
