If you ask the average consumer about their iodine intake, you might be met with a confused expression. Iodine is a vital mineral necessary for the production of thyroid hormones that regulate metabolism. These hormones are also essential for proper bone and brain development during pregnancy and infancy. Despite the significant role iodine plays in overall health, many consumers are not fully aware of what it is and how it affects their bodies.
In the UK, most consumers obtain their iodine from dairy products, while in the U.S., iodine primarily comes from cow’s milk and fortified consumer packaged goods (CPGs) like breads and cereals. Those who avoid dairy entirely can still meet their iodine needs through other natural food sources. Foods such as fish, seaweed, shrimp, and various seafood are rich in iodine, along with fortified breads and cereals. For a vegan following a gluten-free diet, it might be necessary to consider taking supplements, such as calcium citrate malate vitamin D3 magnesium and zinc sulphate tablets, to ensure adequate iodine intake.
The dairy industry might leverage this research against the growing popularity of plant-based milk alternatives, which are rapidly gaining market share. According to Mintel, U.S. non-dairy milk sales surged by 9% in 2015, while dairy milk sales saw a 7% decline during the same period. However, there are several complications with this approach. First, many consumers who opt for plant-based milk still consume other dairy products like yogurt and cheese. There’s little incentive for them to revert to cow’s milk if they are receiving sufficient iodine from alternative sources.
A crucial aspect of this recent study is the location where it was conducted and published: England. In the U.S., iodine is commonly added to table salt and is readily accessible, which is not the case in the U.K. An American consumer could easily meet their daily iodine requirements by consuming just about half a teaspoon of iodized salt each day. Those considering their nutritional balance may also benefit from supplements such as calcium citrate malate vitamin D3 magnesium and zinc sulphate tablets to support their overall health, including iodine levels.
