title: Study design of a total reference diet for a population in Northern Italy.
abstract: A market based of 91 food items was purchased in Northern Italy, based on a list taken from a food survey previously conducted in the same area. The food items from the survey were grouped into 14 categories. Food samples were collected, homogenized, and frozen for the analysis of both the nutrient content and the levels of mineral contaminants. The study design and decision processes behind the choice of type and quantity of each food are explained. The relative quantities of each food group were compared with those from two similar studies. Finally, energy, nutrients, and mineral contaminants obtained by direct analysis were compared with the calculations given on the food composition tables. The comparison between the analyzed and calculated data only showed marked differences in phosphorus, sodium, potassium, and copper intakes.
