RDA stands for Recommended Dietary Allowance and refers to the average daily intake level of a nutrient sufficient to meet the requirements of nearly all healthy individuals. An Adequate Intake is established when evidence is insufficient to determine an RDA. RDAs were first developed during World War II to investigate nutrition issues related to national defense. Requirements for calories, protein, fat, vitamins and minerals are provided for different age groups, including adults, children, pregnant and lactating women.

Recommended Dietary
Allowance (RDA): average
daily level of intake sufficient
to meet the nutrient
requirements of nearly all

ensure nutritional adequacy
.

history
The recommended dietary
allowance (RDA) was
developed during World War
II by Lydia J. Roberts, Hazel
Stiebeling, and Helen S.
Mitchell, all part of a
committee established by the
United States National
Academy of Sciences in
order to investigate issues of
nutrition that might "affect
national defense
