Estimating nutrient intakes from DATs

Once dietary information has been collected using a DAT, nutrient intakes can be calculated. Some studies have used software for this process, and this will be discussed in the study-specific sections.

A simplified overview of this process is depicted in the Estimating nutrient intakes from food frequency questionnaires (FFQs) page below. The exact method depends on the DAT used.
