[Effect of roasted wheat flour on the intestinal absorption and zinc metabolism of rats].
24 experiences have been carried in 8 younger Wistar female rats that been submitted to three different diets considering fibers and phytates, with the purpose to demonstrate if "gofio de trigo" of popular consumption in Canary Islands, and rich in these substances affects intestinal absorption of zinc in the diet. Authors have observed a very significant elevation of zinc in feces, during the control period. An important decrease of zinc in hair has been observed indicating a deficit of corporal ion although zinc in serum remained in its normal limit. Authors emphasize the fact that under these circumstances, removal of urinary zinc is not a useful guide for diagnosis of deficiency state.
