National Food Institute - Technical University of Denmark (DTU) Danish Food Composition Databank - ed. 7.01


Special lists

For certain foods/components, the amount of information is so sparse that a general food entry in the food composition databank is not possible. Instead, special lists are presented.

As an example of such a special list is the mineral content of tap water from 51 localities distributed in all of Denmark.

To begin with, the iodine content of tap water is presented. This will be followed at a later stage by information on additional 12 minerals when the analytical work has been completed.

Iodine content of Danish tap water

In the following list, the average iodine content (µg/100 g) from 47 localities is shown with information on the variation and number of samples. The samples have been taken in households:
