Background: Partially hydrolysed guar gum (Benefiber) added to a diet is fermented in the colon, producing short chain fatly acids, which improve intestinal function, including colonic salt and water absorption. Aims: To evaluate the effect of Bene-fiber supplemented comminuted chicken diet in the treatment of persistent diarrhoea. Methods: One hundred and sixteen children (aged 5-24 months), presenting to Dhaka Hospital with a history of watery diarrhoea for more than 14 days (persistent diarrhoea), were randomised to receive either (1) comminuted chicken diet with Benefiber (study diet); or (2) comminuted chicken diet without Benefiber (control diet). The study period was seven days. Results: Of 116 children, 57 received the study diet and 59 received the control diet. Diarrhoea resolved in a greater number of children with the study than with the control diet (46/55 (84%) v 36/58 (62%); odds ratio 3.12, 95%CI 1.19 to 8.4). Survival analysis for the duration of diarrhoea also showed a reduced duration of diarrhoea in children receiving the study diet. There was also a trend in daily stool reduction in children receiving the study diet, significant on days 4-7. Conclusion: Results show that Benefiber supplemented comminuted chicken diet enhances recovery of children with persistent diarrhoea, indicating its therapeutic potential.
