It is important to be able to determine the actual supply of vitamins and minerals in the population, a procedure that can be carried out by using parameters applied to blood or urine. This is also called nutritional status assessment. At the moment, the intake of vitamins and minerals is determined in the Dutch National Food Consumption Surveys. In these food consumption surveys, dietary monitoring is done via 24-h dietary recalls. Signals of possible inadequate intake (vitamin B2, folate, vitamin B12, vitamin D, magnesium, iron, zinc) and the potential risk of an excessive intake (vitamin D, sodium, zinc) from the surveys can be evaluated through a nutritional status assessment. Information gained through such an assessment can also compensate for the lack of knowledge in the Netherlands about the nutrient supply of iodide, sodium and selenium. And finally, status assessment is recommended as being more practical than dietary monitoring for immigrant groups. Parameters for the vitamins B2, folate, B12 and D, and the minerals magnesium, sodium, iron, iodide, selenium and zinc are also discussed in the report. Although status assessment is also advisable for determination of the supply of vitamin A, calcium and chrome, appropriate parameters are not currently available.
