When you ask the average consumer if they are getting enough iodine, they might respond with a confused expression. Iodine is a vital mineral that the body requires to produce thyroid hormones, which are essential for regulating metabolism. These hormones also play a significant role in proper bone and brain development during pregnancy and infancy. However, despite the crucial function of iodine in maintaining health, many people lack awareness of its importance and how it affects their bodies.
In the UK, consumers primarily obtain their iodine from dairy products, while in the U.S., most iodine comes from cow’s milk and fortified grain-based consumer packaged goods (CPGs) such as breads and cereals. For individuals avoiding all forms of dairy, there are ample natural food sources to meet their iodine needs. Seafood, including fish, seaweed, and shrimp, are excellent sources, along with fortified breads and cereals. Vegans and those following a gluten-free diet may need to consider iodine supplements to ensure they meet their daily requirements. This could be particularly important if they are also taking calcium citrate 200 mg tablets, as dietary balance is crucial.
The dairy industry may attempt to leverage this study to counter the rising popularity of plant-based milk alternatives, which are rapidly capturing market share from traditional dairy products. According to Mintel, sales of non-dairy milk in the U.S. surged by 9% in 2015, while dairy milk sales fell by 7% during the same timeframe. However, there are a few complications with this approach. Many consumers who opt for plant-based milk still consume other dairy items, such as yogurt and cheese, so there’s little incentive for them to revert to cow’s milk if they are receiving adequate iodine from alternative sources.
An important aspect of the study is its context: it was conducted in England, where iodine is not typically added to table salt as it is in the U.S. In America, a consumer could easily meet their daily iodine needs by consuming about half a teaspoon of iodized salt. Given this difference, the conversation around iodine and its sources is essential, particularly for those who might also be taking supplements like calcium citrate 200 mg tablets to ensure they maintain a balanced diet.
