Vitamin D and calcium — updated dietary reference intakes from IOM

Vitamin D and calcium have been the focus of much research since the Institute of Medicine set nutritional reference values for them in 1997. Known as Dietary Reference Intakes, the values for these and other nutrients serve as a guide for good nutrition and provide the scientific basis for the development of food guidelines in both the United States and Canada. Updated DRIs for these two nutrients are presented in a new IOM report, Dietary Reference Intakes for Calcium and Vitamin D, which will be released on Tuesday, Nov. 30.
