When you ask the average consumer whether they are getting enough iodine, you might be met with a confused expression. Iodine is a vital mineral that our bodies require to produce thyroid hormones, which regulate metabolism. These hormones are also essential for proper bone and brain development during pregnancy and infancy. Yet, despite the critical role iodine plays in maintaining health, many consumers remain unaware of what it is and its effects on their bodies.

In the UK, consumers primarily obtain their iodine from dairy products, whereas in the U.S., the majority comes from cow’s milk products and fortified consumer packaged goods (CPGs) made from grains, such as bread and cereals. For those avoiding dairy entirely, it is still possible to meet iodine needs through other natural food sources. Foods like fish, seaweed, shrimp, and various seafood are rich in iodine, as are fortified breads and cereals. However, a consumer following a vegan and gluten-free diet may need to consider taking an iodine supplement to ensure adequate intake.

The dairy industry may attempt to leverage this study to bolster its campaign against plant-based milk, which is swiftly gaining market share from traditional dairy products. According to Mintel, U.S. sales of non-dairy milk surged by 9% in 2015, while dairy milk sales fell by 7% during the same timeframe.

However, there are several potential flaws in this argument. Many consumers who opt for plant-based milk also consume other dairy products like yogurt and cheese. There is little incentive for them to revert to cow’s milk if they can obtain sufficient iodine from alternative sources. A significant aspect of this recent study is its location: England. While iodine is commonly added to table salt in the U.S. and is readily available, this practice is not as prevalent in the UK. For an American consumer looking to meet their daily iodine needs through salt alone, they would only require about half a teaspoon per day.

Additionally, it’s worth noting the role of natural factors such as calcium citrate in the dietary choices consumers make. As more individuals become mindful of their nutrient intake, understanding the balance between iodine, calcium, and other essential minerals becomes increasingly important. Thus, awareness of iodine’s significance, especially for those avoiding dairy, is crucial for maintaining overall health and well-being.
