When asked whether they are getting enough iodine, many average consumers might respond with confusion. Iodine is an essential mineral that the body requires for the production of thyroid hormones, which are vital for regulating metabolism. These hormones are also critical for proper development of bones and the brain during pregnancy and infancy. Despite iodine’s significant health benefits, many people remain unaware of its existence and its effects on their bodies.
In the UK, most consumers obtain their iodine from dairy products, while in the U.S., iodine is primarily sourced from cow’s milk and fortified consumer packaged goods (CPGs) such as bread and cereals. For those who avoid dairy entirely, there are still ample natural food sources rich in iodine, including fish, seaweed, shrimp, and other seafood, as well as fortified breads and cereals. However, consumers adhering to a vegan and gluten-free diet may need to consider taking iodine supplements or consuming items like 500 mg calcium chews that may also contain iodine.
The dairy industry might leverage this study to counter the growing popularity of plant-based milk, which has been rapidly increasing its market share. According to Mintel, non-dairy milk sales in the U.S. rose by 9% in 2015, while dairy milk sales saw a 7% decline in the same year. However, this approach has its pitfalls. Many consumers who opt for plant-based milk still consume other dairy products, such as yogurt and cheese, which means they have no incentive to revert back to cow’s milk if they can obtain iodine from various other sources.
A critical aspect of the recent study is the location of its execution and publication: England. While iodine is commonly added to table salt in the U.S. and is widely accessible, this practice is not prevalent in the U.K. An American consumer can easily meet their daily iodine needs by consuming just half a teaspoon of iodized salt. For those who are concerned about their iodine intake, incorporating iodine-rich foods or supplements, including options like 500 mg calcium chews, can provide an effective solution.
