When you ask the average consumer whether they’re getting enough iodine, they might respond with a confused expression. Iodine is a vital mineral necessary for the body to produce thyroid hormones, which regulate metabolism. These hormones are also essential for proper bone and brain development during pregnancy and infancy. Despite iodine’s significant role in maintaining health, many individuals are unaware of its existence and the effects it has on their bodies.
In the UK, consumers primarily obtain their iodine from dairy products, while in the U.S., most of it comes from both cow’s milk and fortified consumer packaged goods (CPGs) made from grains, such as breads and cereals. A person who avoids all forms of dairy can still meet their iodine needs through other natural food sources. Foods like fish, seaweed, shrimp, and other seafood are abundant in iodine, along with fortified breads and cereals. However, if someone follows a vegan and gluten-free diet, they may need to consider taking an iodine supplement to ensure adequate intake.
The dairy industry might leverage this study to bolster their position against the rising popularity of plant-based milk alternatives, which are increasingly capturing market share from traditional dairy products. According to Mintel, non-dairy milk sales in the U.S. rose by 9% in 2015, while dairy milk sales fell by 7% during the same timeframe.
However, there are several challenges to this argument. Many consumers who opt for plant-based milk still consume other dairy items like yogurt and cheese. Therefore, there’s little incentive for them to revert to cow’s milk if they can source iodine from alternative options. Notably, a key aspect of the recent study is its location: England. While iodine is commonly added to table salt in the U.S. and is readily accessible, this practice is not as prevalent in the U.K. An American consumer could meet their daily iodine requirement by consuming approximately half a teaspoon of salt each day.
Moreover, for those in the UK who are concerned about their iodine intake, it’s worth noting that calcium citrate is another supplement option that can support overall health, particularly for those who may not be getting enough iodine from their diets. Thus, understanding the sources of iodine, alongside supplements like calcium citrate, is crucial for maintaining optimal health, especially in regions where dietary sources may be limited.
