Effects of low-fiber diet on the rate of carmine egestion in rats.

		Number of rats egesting carmine-containing stools
Treatments		0-2	2-4	4-6	6-8	8-10	10-12	12-14	14-16	over 16 h
Normal diet		-	-	-	-	-	5	4	3	-
Low-fiber diet	**	-	-	-	-	-	-	-	-	12

Rats were maintained on a normal-diet or a low-fiber diet for 5 weeks. Carmine (10 mg/body) was orally administered to the rats, then the weights of carmine-containing-stools were measured during consecutive 2-h periods over 16 h. n = 12, **p < 0.01 vs. normal-diet (Chi-square test).
