Salt intake (Indicator 8)


The indicator describes the following: Age-standardised mean population intake of salt (sodium chloride) per day in grams in persons aged 18+ years.

This indicator is part of Target (4): A 30 per cent reduction in the population’s intake of salt/sodium.

We lack information on the salt (sodium chloride) intake of the population of Norway. Measuring salt intake in diet surveys is an imprecise method. Measuring the excretion of sodium in daily urine is an internationally accepted and recommended method of gauging salt intake.

Very few such studies have previously been conducted in Norway. 

Preliminary results

Preliminary results indicate that daily salt intake is around 10 grams for men and 7.5 grams for women. This is clearly higher than the Norwegian national recommendation of a maximum of 6 grams per day but is comparable with countries such as Finland, Denmark, the United Kingdom and Ireland.

The results will be published at a later date. 

Data source: Tromsø Study

The data source for this indicator is the Tromsø Study. A description follows below.


In Tromsø 7 (2015-2016), 24-hour urine collections were obtained from a random sample of approx. 500 people. The examination of salt intake measured via sodium excretion in daily urine was conducted by the Norwegian Institute of Public Health as a sub-project of the Tromsø Study.

Effect measure

Mean salt intake per person per day in grams. The figure forms a preliminary estimate and the age distribution of the population of Norway has not yet been taken into account.

Global indicator definition

Indicator 8. Age-standardised mean population intake of salt (sodium chloride) per day in grams in persons aged 18+ years.
