New research from our members, Professor Margaret Rayman and Dr Sarah Bath, has shown that the iodine concentration of milk alternatives (such as soya and almond drinks) is low. The research sampled 47 drinks in the UK (not those aimed at infants and children) and found that just three were fortified with iodine (as stated on the product label). The unfortified drinks had an iodine concentration that was just 2% of that of cows’ milk. As milk and dairy products are the main source of iodine in the UK diet, those who switch to alternatives will miss out on this source of iodine.
Information on other sources of iodine can be found on our food fact sheet page.
