The added value of food frequency questionnaire (FFQ) information to estimate the usual food intake based on repeated 24-hour recalls.

ABSTRACT:

Background

Statistical methods to model the usual dietary intake of foods in a population generally ignore the additional information on the never-consumers. The objective of this study is to determine the added value of Food Frequency Questionnaire (FFQ) data allowing distinguishing the never-consumers from the non-consumers while modeling the usual intake distribution.
