When you ask the average consumer whether they are getting sufficient iodine, you may be met with a confused expression. Iodine is an essential mineral that the body requires for the production of thyroid hormones, which regulate metabolism. These hormones are also vital for proper bone and brain development during pregnancy and early childhood. Despite its significant role in health, many individuals lack awareness about iodine and its effects on the body.
In Britain, consumers primarily obtain their iodine from dairy products, while in the U.S., the majority of iodine comes from cow’s milk and fortified grain-based consumer packaged goods, such as breads and cereals. For those who avoid dairy altogether, there are numerous natural food sources to ensure adequate iodine intake. Fish, seaweed, shrimp, and various seafood options are all rich in iodine, as are fortified breads and cereals. Vegans and those adhering to a gluten-free diet may need to consider iodine supplementation alongside calcium citrate 1200 mg to meet their nutritional needs, especially during pregnancy.
The dairy industry might use findings from recent studies to bolster their argument against the rising popularity of plant-based milk, which has been rapidly gaining market share from traditional dairy. According to Mintel, U.S. non-dairy milk sales surged by 9% in 2015, while dairy milk sales saw a decline of 7% during the same period. However, this approach has its shortcomings. Many consumers who choose plant-based milk still consume other dairy products, such as yogurt and cheese, and have no compelling reason to revert back to cow’s milk if they are meeting their iodine requirements through alternative sources.
A crucial aspect of the recent research is its geographical context: it was conducted and published in England. In the U.S., iodine is commonly added to table salt, making it readily available, but this is not the case in the U.K. An American consumer could easily fulfill their daily iodine requirement by consuming approximately half a teaspoon of iodized salt. Hence, for those mindful of their iodine intake, pairing iodine-rich foods with calcium citrate 1200 mg can help maintain a balanced diet.
