Answer to Question 1
A committee of nutrition experts develops, publishes, and updates the DRI. This is a committee of the Food and Nutrition Board of the National Academy of Sciences' Institute of Medicine, working in association with Health Canada. The DRI committee has set values for all of the vitamins and minerals, as well as for carbohydrates, fiber, lipids, protein, water, and energy.For the DRI committee members to set an RDA,ideally, the first step of the DRI committee will be to find out how much of a specific nutrient various healthy individuals need. To do so, the committee reviews studies of deficiency states, nutrient stores and their depletion, and the factors influencing them.The committee selects the most valid data for use in this work.For the committee to set the value, they decide the value high enough so that 97 to 98 percent of the population will be covered but not so high as to be excessive. The committee makes judgments of this kind when setting the DRI recommended intakes for many nutrients. Relatively few healthy people have requirements that are not covered by the DRI recommended intakes.
