Indexes of overall diet quality - A review of the literature

Voedingsindexen - Een literatuuroverzicht


A total diet approach provides an appealing way to evaluate the diet of the Dutch population. We have reviewed the existing literature and found that currently used methods contain several drawbacks and limitations and therefore propose to construct a diet quality index specific for the Netherlands using a new approach. Changes in food consumption habits have both positive and negative effects on the health of the Dutch population. However, the exact health consequence cannot be assessed by considering individual nutrients and foods, a common approach. To assess the quality of the diet of the Dutch population, the diet should be considered as a whole. Two distinct methods are commonly used: diet quality scores, that are defined beforehand based on current nutrition knowledge and dietary patterns, derived afterwards from food consumption data using statistical methods. This report contains a critical review of the literature on diet quality scores and dietary patterns.
