In the case of essential minerals, the current military standards are the same as the IOM DRIs and are used to plan operational rations for military personnel. Military surveys suggest that soldiers' mineral intakes might not achieve the levels recommended in the MDRIs.

COMMITTEE'S TASK AND APPROACH Under the auspices of the Standing Committee on Military Nutrition Research, the Committee on Mineral Requirements for Cognitive and Physical Performance of Military Personnel was established to assess the need for setting nutrient intake reference levels specific to the military population and distinct from the IOM DRIs, and, if necessary, to recommend mineral intake levels for military personnel. Specifically, the committee was asked to select essential minerals of importance to military performance and, for those selected minerals, to recommend dietary intake levels for military personnel engaged in garrison training (i.e., training or performing operations from garrison)

In the absence of these data, the committee agreed that basing the current MDRIs on the IOM DRIs is appropriate and recommended that the IOM EARs for appropriate age and gender groups should be adjusted when necessary to set EARs and RDAs for military personnel. In the absence of an IOM EAR, the IOM AI (an estimated intake level that guarantees nutrient adequacy for practically everyone)

The commit tee recommends using the current IOM AI for calcium and the current IOM RDAs for magnesium and selenium as the military requirements. All of the recommended requirements should be updated as new or confirmatory data from appropriately designed studies emerge regarding mineral losses and effects from higher intake doses of specific minerals.

The initial iron status likely will be aggravated by intense physical activity typical of garrison training. There is convincing evidence that iron supplementation improves physical performance of civilian women with low iron stores but no anemia.

In the absence of intake distribution data, the EARMGT cannot be used for the actual planning of cafeteria menus for soldiers, and, for the present, managers should make sure that the food available in the cafeteria contains all the food groups so that the MDRIs are likely to be met and the menus follow nutrition guides such as the Dietary Guidelines for Americans and MyPyramid. Conversely, although variability of nutrient intakes for military personnel eating operational rations is unknown, it can be safely assumed that it will be small if they completely consume the rations issued; therefore, planning rations for individuals (as opposed to planning rations for groups)

The committee concluded that the addition of calcium and magnesium to water consumed by military personnel is warranted only when improving the taste is the desirable outcome. FUTURE NEEDS The committee stresses that the recommendations in this report regarding specific mineral requirements need confirmation based on data collected from

Measurement of Outcomes This experimental design evaluates a doseresponse effect of minerals on ameliorating mineral losses due to heat and sweat and can be used to assess a doseresponse effect of minerals on physical and mental performance. Daily, 24-hour whole-body sweat analysis and potential acclimatization over a short term (five days)

· Determine the magnesium concentrations of food items in operational rations, including MREs and FSRs; estimate the dietary intake levels of military personnel. Specific Research Priorities: Selenium · Quantify selenium losses due to the multiple stressors of garrison training (i.e., heat and physical exertion)
