In 1958 the Army added two grades to the NCO ranks. With the addition of these grades, the ranks of the NCO were corporal, sergeant, staff sergeant, sergeant first class, master sergeant and sergeant major.
DRI is the general term for a set of reference values used to plan and assess nutrient intakes of healthy people. These values, which vary by age and gender, include: Recommended Dietary Allowance (RDA): average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%-98%) healthy people.
The US standards are based primarily on the 1968 Recommended Dietary Allowances (RDAs), whereas the Canadian standards are based on the 1983 Recommended Nutrient Intakes. As the committee noted, it is appropriate to use the new Dietary Reference Intakes (DRIs) as the basis for these reference values. The reference values in the Nutrition Facts box of food and supplement labels (Figure 1â and Figure 2â) are called Daily Values (DVs).
