Abstrakt: Five young women 18 years of age, in good health, with normal serum iron, hemoglobin and red cell counts were placed on a diet containing 7 mg of iron which was judged to be the lowest intake that would be adequate. For 2 weeks minor adjustments were made in the diet and the subjects were accustomed to a 7 mg level. During the next 8 weeks the adjusted basal diet was administered. During the last 4 of the 8 weeks 2 100‐gm patties of ground beef (▪ lean meat and ▪ fat) containing 3.4 mg of iron were added, 1 at breakfast and 1 at lunch. During the 4‐week basal period and the 4‐week beef period, weekly collections of feces were made and during the entire 10 weeks, weekly composites of the foods were preserved for analysis.
