Dietary Reference Intake (DRI) is a system that is used in the U.S. and Canada to guide professionals and citizens on nutrition intake. The Institute of Medicine (IOM) of the U.S National Academy of Sciences is the organization that put this system together.
These guidelines are used when putting together meals for schools, prisons, hospitals, and nursing homes. They also guide industries who are developing new foods.
The DRI has been around since 1997, replacing the former guidelines for nutrition called the Recommended Daily Allowances (RDA). RDA was originally established during World War II when nutrition was seen as a possible national defense issue. The standars were originally used to recommend citizens, armed forces, and overseas populations on what they should be consuming.
