Levels of total iron and available iron were estimated in the diets of individuals 1 year and older. The source of data was 1-day dietary recall records from the U. S. ⋯ When compared with the RDAs, total iron presented a more favorable picture of dietary iron intake than available iron. In relation to the RDAs, proportions of available iron were consistently lower than proportions of total iron. Available iron was lower than total iron in relation to recommended allowances because less than 10% of total dietary iron was available.
