When you ask the average consumer if they are getting enough iodine, you’re likely to be met with confusion. Iodine is a vital mineral that the body requires to produce thyroid hormones, which are essential for regulating metabolism. These hormones also play a critical role in the proper development of bones and the brain during pregnancy and infancy. However, despite iodine’s significant health benefits, many consumers remain uninformed about its importance and sources.
In the UK, most consumers obtain their iodine primarily from dairy products, while in the U.S., it is derived from cow’s milk and fortified consumer packaged goods (CPGs) such as bread and cereals. For those who avoid dairy altogether, there are still plenty of natural food sources rich in iodine, including fish, seaweed, shrimp, and other seafood, as well as fortified breads and cereals. Vegans or those following a gluten-free diet might need to consider an iodine supplement to meet their needs.
Interestingly, the dairy industry may attempt to leverage this information against the rising popularity of plant-based milks, which are increasingly capturing market share from traditional dairy products. According to Mintel, the market for non-dairy milk in the U.S. saw a growth of 9% in 2015, while dairy milk sales fell by 7% during the same period.
However, this strategy may have some flaws. Many consumers who opt for plant-based milk still consume other dairy products, such as yogurt and cheese. Therefore, there is little incentive for them to revert to cow’s milk if they can obtain adequate iodine from alternative sources.
A critical aspect of the recent study is its location: 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 can easily meet their daily iodine requirements through salt intake, needing only about half a teaspoon per day. Additionally, for those looking to enhance their overall nutrient intake, it’s worth noting that a calcium citrate source can also provide essential minerals, complementing iodine-rich foods. By ensuring a balanced diet that includes sources of iodine and calcium citrate, consumers can better support their health.
