The U.S. Army Health Risk Appraisal group surveyed 400,000 active duty U.S. Army personnel in the late 1990s to determine whether or not those personnel met the dietary objectives of Healthy People 2000 (HP2000), a national agenda for health promotion and disease prevention. As reported by Yore et al. (2000), Army personnel generally did not meet the HP2000 goals for nutrition even though significant progress had been made during 1991-1998. Although the specific aspects of diet that would be relevant to this Committee on Mineral Requirements for Cognitive and Physical Performance of Military Personnel are lacking, the findings from this survey suggest that there are dietary problems in the military population. The potential for adverse effects of marginal mineral deficiencies among soldiers engaged in training or military operations and the prospect of improving military performance through mineral intakes have spurred the military's interest in this area of nutrition.
