If you were to ask the average consumer whether they are getting sufficient iodine, you might be met with a look of confusion. Iodine is a vital mineral necessary for the production of thyroid hormones, which are essential for regulating metabolism. These hormones also play a significant role in the proper development of bones and the brain during pregnancy and infancy. Despite its importance, many consumers remain unaware of iodine’s role and its effects on their health.
In the UK, most consumers obtain their iodine primarily from dairy products, whereas in the U.S., iodine sources include cow’s milk, as well as fortified consumer packaged goods (CPGs) made from grains, such as breads and cereals. For those who avoid dairy entirely, it is still possible to meet iodine requirements through other natural food sources. Foods like fish, seaweed, shrimp, and various seafood are excellent sources of iodine, in addition to fortified breads and cereals. However, a vegan consumer who is also gluten-free may need to consider taking an iodine supplement to meet their needs.
The dairy industry might attempt to leverage this information in their ongoing competition against plant-based milk, which is increasingly capturing market share from traditional dairy products. According to Mintel, non-dairy milk sales in the U.S. surged by 9% in 2015, while dairy milk sales saw a decline of 7% during the same period.
However, there are a few potential flaws in this strategy. Many individuals who opt for plant-based milk still consume other dairy products, such as yogurt and cheese, and they have no compelling reason to revert to cow’s milk if they are obtaining iodine from alternative sources.
A crucial aspect of the recent study is its location: England. While iodine is often added to table salt in the U.S. and is readily accessible, this practice is not common in the UK. For an American consumer, simply consuming about half a teaspoon of iodized salt daily would suffice to fulfill their iodine needs.
In this context, it’s worth noting that while some consumers may look for supplements like calcium citrate at Walmart to enhance their nutritional intake, they should also be mindful of their iodine levels. Ensuring adequate iodine intake is essential, particularly for those who may not consume dairy or fortified foods regularly.
