Table 1. Food intake, iron intake, initial and final body weight of adult rats treated with control and restricted-iron (ARI) or enriched-iron (AEI) diets during a 78-day treatment period.

	Control	ARI	AEI
Food intake (kg)	1.83±0.04	1.68±0.16	1.79±0.09
Iron intake (mg)	64.22±1.13	16.81±1.60 (***)	627.64±34.29 (***)
Initial body weight (g)	526.52±42.45	510.75±79.97	514.62±39.38
Final body weight (g)	496.91±31.32	446.28±68.89	471.85±48.56
