What are RDA's?

Answer 1

in dentistry it stands for Registered Dental Assistant. i was a certified dental assistant (CDA) and i assisted the dentist, but as an RDA you have expanded functions and you can do more things. pretty much its the person assisting the dentist and performs a range of services that a CDA is not certified to do, and pretty much it allows the dentist to go on to other patients and be more efficient.

Answer 2

Recommended Dietary Allowance (RDA).

The RDA was developed during World War II by Lydia J. Roberts, Hazel K. Stiebeling and Helen S. Mitchell under the auspices of the National Research Council. The National Research Council determined that a set of dietary standards were needed, especially given the possibility that rations would be needed during the war. The standards would be used for nutrition recommendations for the armed forces, for civilians, and for overseas population who might need food relief. Roberts, Stiebeling, and Mitchell surveyed all available data, created a tentative set of allowances, and submitted them to experts for review. The final set of allowances were accepted in 1941. The allowances were meant to provide superior nutrition for civilians and military personnel, so they included a "margin of safety."

The RDA was established by the Food and Nutrition Board of the (US) National Academy of Sciences.

In 1997 at the suggestion of the Institute of Medicine of the National Academy RDA became one part of a broader set of dietary guidelines called the Dietary Reference Intake used by both the United States and Canada.
