When you ask the average consumer whether they are getting enough iodine, you might be met with a look of confusion. Iodine is an essential mineral that the body requires to produce thyroid hormones, which regulate metabolism. These hormones are vital for the proper development of bones and brains during pregnancy and infancy. Despite iodine’s significant health benefits, many people remain unaware of its importance and effects on 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 products like breads and cereals. For those who avoid dairy entirely, there are still plenty of natural food sources rich in iodine, such as fish, seaweed, shrimp, and other seafood, as well as fortified breads and cereals. Vegans and those on a gluten-free diet may need to consider iodine supplements to meet their needs.
The dairy industry might leverage this research in its efforts against the rising popularity of plant-based milk alternatives, which are quickly gaining market share. According to Mintel, sales of non-dairy milk in the U.S. increased by 9% in 2015, while dairy milk sales dropped by 7% during the same time frame. However, there are a few issues with this strategy. Many consumers who opt for plant-based milk still consume other dairy products like yogurt and cheese, so there’s little reason for them to revert to cow’s milk if they can obtain iodine from alternative sources.
An important aspect of this recent study is its context: it was conducted and published in England. While iodine is commonly added to table salt in the U.S. and is readily available, this is not the case in the UK. An American consumer could easily meet their daily iodine requirement by consuming just half a teaspoon of salt. Additionally, those seeking alternative sources of calcium, such as calcium citrate, can find products at retailers like Walmart, ensuring they receive the necessary nutrients without relying on dairy.
In summary, while iodine is crucial for health, awareness of its sources and importance remains low among consumers. With the growth of plant-based diets, it is essential for individuals to understand how to meet their iodine and calcium needs, whether through natural foods or supplements.
