Importance of details in food descriptions in estimating population nutrient intake distributions.

ABSTRACT:

Background

National food consumption surveys are important policy instruments that could monitor food consumption of a certain population. To be used for multiple purposes, this type of survey usually collects comprehensive food information using dietary assessment methods like 24-h dietary recalls (24HRs). However, the collection and handling of such detailed information require tremendous efforts. We aimed to improve the efficiency of data collection and handling in 24HRs, by identifying less important characteristics of food descriptions (facets) and assessing the impact of disregarding them on energy and nutrient intake distributions.

Methods

In the Dutch National Food Consumption Survey 2007-2010, food consumption data were collected through interviewer-administered 24H
