To compare the traditional yogurt and probiotic yogurt in improving acute noninflammatory gastroenteritis. A double blinded case-control clinical trial, performed in 100 patients aged 6 months to 12 years of age from October 2008 to September 2009 in Ghaem and Dr. Sheikh Hospitals in Mashhad, Iran. The patients were assigned to the following groups: the case group received a probiotic yoghurt and the control group received the ordinary yogurt. There were statistically significant differences between the case and control groups in reducing frequency of diarrhea in the first [p= 0.000], second [p=0.013], third [p=0.028], and fourth [p=0.022], therapy. Also, there was a significant difference [p=0.000] in discontinuation of diarrhea between the case and control groups. Acute non- inflammatory gastroenteritis improvement is accelerated by probiotic yogurt consumption
