Mice on powdered diets containing 35 mg/kg iron exhibit better glucose tolerance than mice fed the same powdered diet supplemented with carbonyl iron to 500 mg/kg. Ob/ob mice (10/group) were placed on the powdered diet containing 35 mg/kg iron, with or without added carbonyl (elemental) iron, to total 500 mg/kg. Glucose tolerance testing was performed at 6 wk (A), at which time the mice were also weighed (B). Individual glucose values are significantly different at 30, 60, and 120 min.
