When you ask the average consumer if they are getting enough iodine, you might be met with a puzzled expression. Iodine is an essential mineral that the body requires to produce thyroid hormones, which regulate metabolism. These hormones are particularly important for the proper development of bones and brains during pregnancy and infancy. Despite iodine’s significant role in health, many consumers lack awareness about its importance and effects on their bodies.
In the UK, most consumers obtain their iodine from dairy products, whereas in the U.S., iodine is primarily sourced from cow’s milk and fortified grain products such as breads and cereals. Those who avoid dairy entirely can still meet their iodine needs through other natural food sources. Seafood, including fish, seaweed, and shrimp, are excellent sources of iodine, along with fortified breads and cereals. However, a vegan and gluten-free consumer might need to consider taking an iodine supplement to ensure adequate intake.
The dairy industry could potentially leverage this information as part of their strategy against the growing popularity of plant-based milk, which has been rapidly gaining market share. According to Mintel, non-dairy milk sales in the U.S. increased by 9% in 2015, while dairy milk sales fell by 7% during the same period.
However, there are a few flaws in this argument. Many consumers who opt for plant-based milk still consume other dairy items like yogurt and cheese. If they’re receiving sufficient iodine from alternative sources, there’s little incentive to revert to cow’s milk. One crucial aspect of this study is its location: England. While iodine is commonly added to table salt in the U.S., this practice is not prevalent in the UK. An American consumer could easily obtain their daily iodine requirement by consuming just half a teaspoon of iodized salt.
Additionally, it’s worth noting that some individuals are turning to supplements like calcium citrate, as suggested by Dr. Berg, to enhance their overall nutrition. This type of supplement can help ensure that they receive essential minerals, including iodine, especially in diets that may lack adequate dairy or seafood sources. Hence, awareness of iodine’s role and the availability of supplements like calcium citrate can play a pivotal role in maintaining health.
