Duplicate plate technique is currently the most reliable method to measure dietary intake of nutrients. However, there is no control for alterations in the diet, conscious or subconscious, due to the collection process. Duplicate diet samples were collected by 19 adult subjects, 11 females (F) and 8 males (M), while consuming freely-chosen diets. Subjects were then placed on a controlled diet to determine actual caloric requirement. Most subjects consumed fewer calories during the freely-chosen diet collection day than their actual caloric requirement. The ratio of the determined caloric intake to the calories measured in the duplicate plate sample varied from 0.90 to 2.2. The data demonstrate that derived nutrient intake may be a better measurement of actual intake than duplicate technique alone.
