Through collaboration between the dairy industry, advisors, feed companies, and others, the iodine content in Swedish milk has improved. This is shown by data from LRF (Lantbrukarnas Riksförbund).
Milk is a good source of iodine, but from 2001 to 2019, the iodine content in Swedish milk decreased from 16 micrograms to 10 micrograms per 100 grams of milk. This is evidenced by LRF Milk’s ongoing analyses of Swedish milk.
In March 2024, follow-up analyses showed that the iodine content had recovered to 22 micrograms per 100 grams of milk. This means that Swedish milk is now at the same level as milk produced in Finland and Norway.
– Iodine is one of the most important nutrients in milk. Therefore, it is important that we can continue to be confident that milk is a good source of iodine and maintains a level that allows us to declare iodine in the milk’s nutritional value table, says Ann-Kristin Sundin, LRF’s nutrition expert.
The reason for the decline in iodine in Swedish milk in recent years is unclear. A probable cause is the increased use of rapeseed products in cow feed. Several studies have shown that rapeseed products can inhibit the uptake of iodine.
