Food-based oral rehydration salt solution for acute childhood diarrhoea.

The efficacy in acute childhood diarrhoea of oral rehydration therapy (ORT) based on staple foods (maize, millet, wheat, sorghum, rice, or potato) was compared with that of standard ORT based on glucose. 266 children aged 1-5 years, with a history of acute diarrhoea for 48 h or less, moderate to severe dehydration, and no complications, were assigned to treatment with one of the food-based oral rehydration salt solutions (ORS) or standard ORS. The mean stool output over the first 24 h of treatment in the group receiving standard ORS was significantly higher than that of any other treatment group, and the groups receiving food-based ORT showed substantial reductions in stool output compared with the standard ORT group. Abnormalities in electrolyte concentrations were corrected in all treatment groups with similar efficiency. The digestibility of the food-based ORS was assessed by the stool pH, glucose content before and after acid hydrolysis, and osmolality; there were no significant differences between the standard ORS and food-based ORS groups. Food-based ORT should be more acceptable to users in developing countries since the mixtures are similar to traditional weaning foods and since, unlike standard ORT, it reduces stool output substantially.
