Some imp facts about RDA:
It is defined as the amount of the nutrient sufficient for the maintenance of health in nearly all people.
They are reference standards of nutritional intakes.
For all nutrients except energy, estimates of allowances are based on the defined minimum requirement plus a safety margin often generous.
In some cases this has entailed adding to the observed mean, twice the SD of the distribution of the minimum requirement for the subjects measured. It is important to emphasize that the RDA of nutrients does not apply to sick people.
