Does colour variety accurately quantify nutritional value in children's lunchboxes? A pilot study

Objectives

In advocating a diet rich in fruit and vegetables, public health authorities emphasise dietary colour variety to ensure adequate nutrient consumption. The relationship between food colour variety and nutritional value in children's lunches attending one school was evaluated.
