If you ask the average consumer whether they’re getting enough iodine, you’re likely to be met with a confused expression. Iodine is a crucial mineral that the body requires to produce thyroid hormones, which are essential for regulating metabolism. These hormones also play a vital role in the proper development of bones and the brain during pregnancy and infancy. Despite iodine’s significant contributions to health, many consumers lack awareness of what it is and how it affects their bodies.
In the U.K., consumers primarily obtain their iodine from dairy products, while in the U.S., most iodine comes from cow’s milk and fortified consumer packaged goods (CPGs) made from grains, such as bread and cereals. A person who avoids all dairy can still meet their iodine needs through other natural food sources. Foods like fish, seaweed, shrimp, and various seafood are rich in iodine, as are fortified breads and cereals. For those following a vegan and gluten-free diet, taking an iodine supplement may be necessary.
The dairy industry might attempt to leverage this research in their ongoing battle against plant-based milk, which is increasingly capturing market share from traditional dairy. According to Mintel, U.S. non-dairy milk sales surged by 9% in 2015, whereas dairy milk sales fell by 7% during the same timeframe.
However, there are a few potential flaws in this argument. Many consumers who opt for plant-based milk still consume other dairy products, such as yogurt and cheese. Therefore, they would have no reason to revert to cow’s milk if they can obtain iodine from alternative sources. Moreover, an essential aspect of this recent study is its location: England. While iodine is commonly added to table salt in the U.S. and is readily available, the same cannot be said for the U.K. An American consumer could meet their daily iodine requirement simply by consuming about half a teaspoon of salt.
For those concerned about their iodine intake, considering supplements like UpCal D calcium citrate powder may be beneficial, especially if they are on restrictive diets. This powder can help ensure adequate mineral intake, including iodine, in conjunction with a balanced diet. Ultimately, raising awareness about iodine’s importance and exploring dietary options, including the use of supplements like UpCal D calcium citrate powder, can help consumers maintain optimal health.
