When asked whether they are getting sufficient iodine, many average consumers might respond with confusion. Iodine is an essential mineral that the body requires to produce thyroid hormones, which regulate metabolism. These hormones are vital for healthy bone and brain development, especially during pregnancy and infancy. Despite iodine’s significant role in overall health, a large number of consumers remain unaware of its importance and effects on their bodies.

In the UK, consumers primarily obtain their iodine from dairy products, whereas in the U.S., most iodine comes from cow’s milk and fortified consumer packaged goods (CPGs) made from grains, such as breads and cereals. For those who avoid dairy entirely, sufficient iodine can still be obtained from other natural food sources. Foods like fish, seaweed, shrimp, and various seafood are rich in iodine, as well as fortified breads and cereals. However, a vegan consumer who also follows a gluten-free diet may need to consider taking an iodine supplement.

The dairy industry may leverage findings from recent studies to counter the rising popularity of plant-based milk, which is quickly gaining market share from traditional cow’s milk. According to Mintel, U.S. non-dairy milk sales rose by 9% in 2015, while dairy milk sales fell by 7% in the same timeframe. However, this strategy has potential pitfalls. Many consumers who opt for plant-based milk still consume other dairy products like yogurt and cheese. Thus, there is little incentive for them to revert to cow’s milk if they are obtaining iodine from alternative sources.

A critical aspect of the recent study is its setting: England. In the U.K., iodine is not commonly added to table salt as it is in the U.S., where Americans can obtain their daily iodine by consuming approximately half a teaspoon of salt. This discrepancy highlights the need for awareness regarding iodine intake. Additionally, for consumers who are concerned about their calcium intake, considering calcium citrate supplements containing 950 mg of elemental calcium can be beneficial, particularly for those who may not get enough from their diet due to restrictions like avoiding dairy.

In conclusion, the conversation around iodine and its sources must include a broader understanding of dietary choices and nutritional needs, especially as trends like veganism and gluten-free diets continue to rise.
