Brief Summary

A new dietary trend is switching from cow\'s milk to plant-based milk alternatives, driven by the belief that this switch is beneficial for health reasons in addition to the sustainability aspect of a plant-based diet. The trend of using plant-based milk alternatives is especially popular among young women, of whom iodine nutrition also is of concern, both globally and in Norway. Some of the plant-based alternatives are fortified with iodine, but both the bio-availability and whether is feasible to consume large enough amounts of the milk to provide an adequate iodine intake is unknown. Another aspect is that the effect of cow's milk intake on blood lipids has been widely studied, however, there is a lack of studies on the effect of oat milk consumption on blood lipids.
