Iron Dietary Reference Intake

This recommendation relates to breast fed babies.

Iron dietary reference intake. Predicted absorption values at a serum ferritin concentration of 30 µg l of 16 for men and 18 for women were used to convert physiological requirements to dietary iron intakes.

The dris represent the most current scientific knowledge on nutrient needs of healthy populations.

These include average requirement ar and population reference intake pri. Beans like black beans navy beans and kidney beans can all help easily bump up your iron intake. Mostly a hereditary disease hemochromatosis is the result of a genetic mutation that leads to abnormal iron metabolism and an accumulation of iron in certain tissues such as the liver pancreas and heart.

On the basis of intake data and isotope studies iron bioavailability has been estimated to be in the range of 14 18 for mixed diets and 5 12 for vegetarian diets in subjects with no iron stores and these values have been used to generate dietary reference values for all population groups. For adults whole body iron losses were modelled using data from us adults. The ai for 0 6 months was calculated by multiplying the average intake of breast milk 0 78 l day by the average concentration of iron in breast milk 0 26 mg l and rounding butte et al 1987 dewey lonnerdal 1983 lipsman et al 1985 picciano guthrie 1976 vaughan et al 1979.

Dri is the general term for a set of reference values used for planning and assessing. The iron in formula is much less. Please note that individual requirements may be higher or lower than the dris.

Based on a heme iron intake of 11 percent of total iron for children 1 to 8 years old the upper limit of absorption is 18 percent see factors affecting the iron requirement algorithms for estimating dietary iron bioavailability and appendix table i 2. The dietary reference intakes dris are developed and published by the institute of medicine iom. The iom has set tolerable upper intake levels of iron table 11 2 dietary reference intakes for iron.
