When you ask the average consumer whether they are getting enough iodine, you’re likely to receive a confused expression in response. Iodine is an essential mineral that the body requires for the production of thyroid hormones, which are vital for regulating metabolism. These hormones also play a key role in the healthy development of bones and the brain during pregnancy and infancy. Despite the significant role iodine plays in overall health, many consumers remain unaware of its importance and sources.
In the UK, most consumers obtain their iodine primarily from dairy products, while in the U.S., iodine is mainly sourced from both cow’s milk and fortified consumer packaged goods (CPGs) made from grains, such as bread and cereals. A consumer who avoids dairy completely can still obtain sufficient iodine from various natural food sources. Foods like fish, seaweed, shrimp, and other seafood are abundant in iodine, along with fortified breads and cereals. However, for those who are vegan and gluten-free, it may be necessary to consider an iodine supplement.
Interestingly, the dairy industry might attempt to leverage this study to counter the growing popularity of plant-based milk, which is rapidly gaining market share from traditional cow’s milk products. According to Mintel, U.S. sales of non-dairy milk climbed by 9% in 2015, while dairy milk sales saw a decline of 7% during the same timeframe.
However, there are several issues with this approach. Firstly, numerous consumers who prefer plant-based milk still consume other dairy items like yogurt and cheese, so there is little incentive for them to revert to cow’s milk if they can obtain iodine from alternative sources. A critical aspect of this recent study is its location: England. Unlike the U.S., where iodine is commonly added to table salt and is readily available, this practice is not as prevalent in the U.K. An American consumer aiming to meet their daily iodine requirement through salt alone would only need to consume about half a teaspoon each day.
Moreover, it’s worth noting that calcium citrate plus magnesium can also play a role in overall mineral balance, and consumers should be aware of their intake of various essential nutrients, including iodine. The inclusion of calcium citrate plus magnesium in a balanced diet can further support health, particularly for those who may not be getting enough iodine from their food sources. Therefore, understanding the importance of iodine, along with other minerals like calcium citrate plus magnesium, is crucial for maintaining optimal health.
