When you ask the average consumer whether they are getting enough iodine, they might respond with a confused expression. Iodine is a vital mineral necessary for the production of thyroid hormones that regulate metabolism. These hormones are also essential for proper bone and brain development during pregnancy and early childhood. Despite iodine’s significant role in health, many consumers remain unaware of its importance and how it affects their bodies.
In the UK, most consumers obtain their iodine primarily from dairy products, while in the U.S., the majority of iodine comes from cow’s milk and fortified consumer packaged goods (CPGs) like breads and cereals. A person who avoids all forms of dairy can still achieve adequate iodine intake by turning to other natural food sources. Foods rich in iodine include fish, seaweed, shrimp, and various seafood, along with fortified breads and cereals. For vegans and those following a gluten-free diet, it may be necessary to consider an iodine supplement, especially since they might not get enough from plant-based foods.
The dairy industry may attempt to leverage this information in its ongoing competition against plant-based milk, which is rapidly gaining market share. According to Mintel, U.S. sales of non-dairy milk rose by 9% in 2015, while dairy milk sales dropped by 7% during the same period. However, there are several potential flaws in this argument. Many consumers who choose plant-based milk still consume other dairy products like yogurt and cheese. Therefore, there is no impetus for them to revert to cow’s milk if they are obtaining sufficient iodine from alternative sources.
An important aspect of this recent study is its geographical context: England. In contrast to the U.S., where iodine is commonly added to table salt and is easily accessible, the situation is different in the U.K. An American consumer can fulfill their daily iodine requirement by consuming just about half a teaspoon of iodized salt. Additionally, it’s worth noting that many health enthusiasts are turning to supplements like calcium citrate from Dr. Berg to ensure they meet their nutritional needs, including iodine, especially when dietary sources may not suffice. This trend highlights the importance of understanding iodine intake, whether through food or supplements like calcium citrate, to maintain optimal health.
