Intake recommendations for zinc and other nutrients are provided in the dietary reference intakes dris developed by the food and nutrition board fnb at the institute of medicine of the national academies formerly national academy of sciences.
Dietary reference intakes zinc. 12 milligrams per day 9 to 13 years. The dris represent the most current scientific knowledge on nutrient needs of healthy populations. The objective of this project was to estimate the effects of increasing. The dietary reference intakes dris are developed and published by the institute of medicine iom.
We compared the sources of the data the concepts and methods used by the 4 expert groups to set the physiological requirements for absorbed zinc the dietary zinc requirements termed estimated and or average requirements recommended dietary allowances or recommended nutrient intakes or population reference intakes and tolerable upper intake levels for selected age sex and life stage. Dri is the general term for a set of reference values used for planning and assessing nutrient. The national academies of sciences engineering and medicine health and medicine division has set dietary reference intakes dris for zinc based on age. Dietary reference intakes 1 to 3 years.
The use of zinc stable isotopes to inform the dietary reference intake process for infants and children presenter. The quantity of total dietary zinc zn and phytate are the principal determinants of the quantity of absorbed zn. Although urinary zinc losses decrease markedly with severe deficiency baer king 1984 across a dietary intake range of 4 25 mg day urinary zinc and non intestinal losses in general appears to be largely independent of dietary intake. Recent estimates of dietary reference intakes dri for zn by the institute of medicine iom were based on data from low phytate or phytate free diets.
