If you were to ask the average consumer whether they are getting enough iodine, you might be met with a look of confusion. Iodine is a crucial mineral that the body requires to produce thyroid hormones, which regulate metabolism. These hormones are also vital for the proper development of bones and the brain during pregnancy and infancy. Despite its significant role in health, many people remain unaware of what iodine is and its effects on their bodies.
In the UK, consumers primarily obtain their iodine from dairy sources, while in the U.S., the majority comes from cow’s milk products and fortified consumer packaged goods (CPGs) made from grains, such as breads and cereals. A person who avoids all dairy can still get sufficient iodine from other natural food sources. Fish, seaweed, shrimp, and various seafood are all rich in iodine, in addition to fortified breads and cereals. For those who are vegan and gluten-free, considering an iodine supplement may be necessary.
The dairy industry might leverage this information in their efforts to counter the rise of plant-based milk, which has been steadily gaining market share from traditional dairy products. According to Mintel, non-dairy milk sales in the U.S. increased by 9% in 2015, while dairy milk sales fell by 7% during the same timeframe. However, there are a few potential flaws in this strategy. Many consumers who opt for plant-based milk still consume other dairy products, such as yogurt and cheese. If they are getting enough iodine from alternative sources, there is little incentive for them to revert to cow’s milk.
A critical aspect of this study is the country in which it was conducted and published: England. Unlike the U.S., where iodine is commonly added to table salt and is readily available, this is not the case in the UK. An American consumer could meet their daily iodine requirement by consuming only about half a teaspoon of iodized salt each day.
Moreover, for those focused on bone health, incorporating calcium citrate may be beneficial, especially in conjunction with iodine intake. This combination can support overall health, particularly for those who are pregnant or in their early developmental stages. As the conversation around nutrition continues to evolve, it’s essential to consider the role of various minerals, including iodine and calcium citrate, in our diets.
