In terms of food sources of vitamin D, our results agree well
with current knowledge.
Fatty fish such as salmon or herring is
a well-established good source of naturally occurring vitamin D.
The contribution of 28% of vitamin D from canned fish for this
study population is fairly high, considering that only 2% of the
participants ate one serving of canned fish per day, and 45% of
participants ate one serving of canned fish per week.
There is therefore large potential to raise vitamin D intake if consumption
of fish is increased.
