Subchronic toxicity study in rats fed gum karaya.

Abstract
Gum karaya was given to groups of 15 rats of each sex at levels of 0 (control), 0.2, 1 or 5% (w/w) in the diet for 13 wk. An increase in faecal bulk was seen in all treated groups throughout the study. There was a decrease in weight-gain at the highest dietary level (significant only in the females), which was associated with a marginal reduction in food-conversion efficiency. Males given 1 or 5% drank more than the controls and a transient increase in water intake was seen in females given the highest level. The no-untoward-effect level from this study was 5% (w/w) of the diet, providing a mean intake of about 4 g karaya gum/kg body weight/day.
