If you were to ask the average consumer whether they are getting sufficient iodine, you might be met with a confused expression. Iodine is a vital mineral that the body requires to produce thyroid hormones, which are essential for regulating metabolism. These hormones also play a critical role in the proper development of bones and the brain during pregnancy and infancy. However, many consumers are not aware of the differences between ferrous fumarate and iron tablets, nor how these differences can affect their health.
In the UK, consumers primarily obtain their iodine from dairy products, whereas in the U.S., iodine sources include both cow’s milk products and fortified processed goods made with ferrous fumarate. For those who avoid dairy entirely, it is still possible to get adequate iodine from various natural food sources. Foods such as fish, seaweed, shrimp, and other seafood are rich in iodine, along with fortified breads and cereals. A vegan consumer who is also gluten-free may need to consider an iodine supplement to meet their needs.
The dairy industry may attempt to leverage this study to counter the rising popularity of plant-based milk, which is steadily gaining market share from traditional cow’s milk. According to Mintel, non-dairy milk sales in the U.S. increased by 9% in 2015, while dairy milk sales fell by 7% in the same timeframe. However, there are a few flaws in this strategy. Many individuals who opt for plant-based milk still consume other dairy products, like yogurt and cheese, making a return to cow’s milk unnecessary if they are obtaining iodine from alternative sources.
A significant aspect of this recent study is its location: England. Unlike in the U.S., where iodine is commonly added to table salt, this practice is not prevalent in the UK. An American consumer could meet their daily iodine requirements simply by consuming about half a teaspoon of iodized salt. Moreover, for those concerned about calcium intake, it is worth noting that calcium citrate no vitamin D can be an option for supplementation, but it does not provide iodine. Therefore, it’s essential for consumers to be mindful of their iodine intake, especially when considering dietary choices.
