Guar gum reduces the incidence of streptozotocin-induced renal tumors in Wistar rats

The effect of feeding guar gum or bran fibre diets upon the incidence of renal tumors was examined in streptozotocin diabetic rats. Guar gum fed rats gained significantly less weight during the first 14 weeks of the study than the bran fibre group.
