If you ask the average consumer whether they’re getting enough iodine, you’re likely to see a confused expression in response. Iodine is a vital mineral that the body requires for the production of thyroid hormones, which play a significant role in regulating metabolism. These hormones are essential for proper bone and brain development during pregnancy and infancy. However, despite iodine’s crucial contribution to health, many consumers remain unaware of its significance and effects on their bodies.
In the U.K., consumers primarily obtain their iodine from dairy products, while in the U.S., most iodine comes from both cow’s milk products and fortified consumer packaged goods (CPGs) made from grains, such as breads and cereals. A consumer who avoids dairy entirely can still meet their iodine needs through other natural sources. Foods like fish, seaweed, shrimp, and various seafood are rich in iodine, as are fortified breads and cereals. For those who follow a vegan and gluten-free diet, considering an iodine supplement may be necessary.
It’s worth noting that the dairy industry might leverage this study to bolster their argument against the growing popularity of plant-based milk, which is rapidly gaining market share from traditional dairy products. According to Mintel, U.S. non-dairy milk sales increased by 9% in 2015, while dairy milk sales fell by 7% during the same timeframe.
However, there are a couple of potential issues with this approach. First, many consumers who opt for plant-based milk still consume other dairy items like yogurt and cheese. If they are obtaining adequate iodine from alternative sources, there is little reason for them to revert to cow’s milk. Additionally, an important aspect of this recent study is its location: England. Unlike the U.S., where iodine is often added to table salt and is readily available, this practice is not as common in the U.K. An American consumer could meet their daily iodine requirements by consuming approximately half a teaspoon of salt each day.
Moreover, in considering overall mineral intake, it’s also important to recognize the roles of calcitriol, calcium citrate, and zinc sulfate in maintaining proper health. While iodine is essential for thyroid function, these minerals contribute to bone health and immune function, respectively. Balanced nutrition is crucial, and for individuals focusing on plant-based diets, ensuring adequate intake of iodine, calcitriol, calcium citrate, and zinc sulfate is vital for overall well-being.
