If you ask the average consumer whether they are getting enough iodine, you might receive a confused expression in response. Iodine is a vital mineral necessary for the production of thyroid hormones, which regulate metabolism. These hormones are also essential for proper bone and brain development during pregnancy and infancy. Despite the significant role iodine plays in health, many consumers remain uninformed about its importance and how it affects their bodies.
In the U.K., most consumers obtain their iodine primarily from dairy products, while in the U.S., the majority comes from cow’s milk and fortified consumer packaged goods (CPGs) such as breads and cereals. For those avoiding dairy, it is still possible to meet iodine requirements through other natural food sources. Foods like fish, seaweed, shrimp, and various seafood are rich in iodine, alongside fortified breads and cereals. However, a vegan consumer who is also gluten-free might need to consider an iodine supplement to ensure adequate intake.
The dairy industry may leverage findings from this study to bolster its arguments against the growing popularity of plant-based milk, which is rapidly gaining market share from traditional dairy products. According to Mintel, U.S. sales of non-dairy milk increased by 9% in 2015, while sales of dairy milk fell by 7% during the same timeframe.
However, there are several issues with this approach. Many consumers who opt for plant-based milk still incorporate other dairy items, such as yogurt and cheese, into their diets. There’s no compelling reason for them to revert to cow’s milk if they are obtaining sufficient iodine from alternative sources. Furthermore, 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 widely accessible, this practice is not common in the U.K. An American consumer can meet their daily iodine needs by consuming approximately half a teaspoon of iodized salt.
In this context, it is essential for consumers to explore various options for maintaining their iodine levels, including potential supplements like Solgar Liquid Calcium Magnesium with Vitamin D3, which can support overall health. Ultimately, whether they consume dairy or not, consumers should be aware of their iodine intake to ensure their well-being.
