Abstract

Juice Valley and Gogu Valley were administered to twelve healthy young volunteers for 4 weeks to study their clinical effects on human intestinal microflora. Changes in fecal microflora, fecal moisture, and fecal pH were observed for Juice Valley intake. Administration of Juice Valley significantly increased numbers of Bifidobacterium and Lactobacillus from 8.69 and 7.02 to 10.89 and 9.02 (Log CFU/g wet feces), respectively, whereas those of Clostridium perfringens and Escherichia coli decreased. Moisture content of feces increased, and fecal pH decreased after 4 weeks of Juice Valley intake, intake of Gogu Valley slightly increased growth responses of Bifidobacterium and Lactobacillus and decreased growth responses of C. perfringens and E. coli. Su-mi potato, as a reference, had no effect on Bifidobacterium and Lactobacillus numbers. This study confirmed Juice Valley has better effects than Gogu Valley and Su-mi, and has important role on growth promotion and inhibition of human intestinal bacteria.
