Less iodine in food: risks for pregnant women

Over the past 15 years, the amount of iodine we ingest in the Netherlands through our diet has fallen by a third. This is mainly because the law was changed in 2008 and there is less iodine in the salt that is added to bread. According to a study that the RIVM has done with Lifelines data, men who live in the Northern Netherlands generally get enough iodine. Of women who fall into the age group in which you have children (18-40 years), half appear to be below an intake of 149 micrograms per day. The chance of problems with public health is therefore small, RIVM says, but the amount of iodine should not fall further.

Pregnant women

The researchers are concerned about this. Pregnant women need about twice as much iodine, but often do not know that, says Janneke Dijck-Brouwer. ‘The importance of this cannot be underestimated. Too little iodine can lead to a defective brain development and growth problems in the child.’

A study she did with Frits Muskiet in 2018 showed that 83 percent of the highly educated pregnant women studied did not get the amount of iodine recommended by the WHO. Despite the fact that 61 percent of the group studied took iodine supplements. In 2000, they did a larger study among 200 pregnant women, and this picture was confirmed. In the meantime, RIVM has started an investigation into the intake of iodine among pregnant women.

Fish, shells and seaweed

Frits Muskiet, Janneke Dijck-Brouwer and Gertjan Schaafsma believe that we should ensure that we consume more iodine. They are calling for a reversal of the decision for less iodine in baking soda and a nationwide campaign to eat more fish, shellfish and seaweed. ‘That is not only good for the intake of iodine and selenium,’ says Frits. ‘You also get many other good substances, such as vitamins A, D and B12, iron, zinc, copper and fish oil fatty acids’ Women who are pregnant or want to become pregnant are advised to consider taking not only folic acid, but also iodine. to swallow.
