When you ask the average consumer if they are getting enough iodine, you might be met with a confused expression. Iodine is a vital mineral that the body requires to produce thyroid hormones, which are essential for regulating metabolism. These hormones are also critical for proper bone and brain development during pregnancy and infancy. However, many consumers remain unaware of iodine’s significance and its effects on their health.
In the UK, most consumers obtain their iodine primarily from dairy products, while in the U.S., iodine is largely sourced from cow’s milk and fortified consumer packaged goods (CPGs) made from grains, such as breads and cereals. For those who avoid dairy entirely, there are ample natural food sources to provide sufficient iodine. Fish, seaweed, shrimp, and various seafood are abundant in iodine, as are fortified breads and cereals. However, if a consumer follows a vegan and gluten-free diet, they may need to consider taking an iodine supplement to meet their nutritional needs.
The dairy industry might attempt to leverage this study as a defense against the growing popularity of plant-based milk, which is increasingly capturing market share from traditional dairy. According to Mintel, U.S. sales of non-dairy milk increased by 9% in 2015, while dairy milk sales fell by 7% during the same period. Nevertheless, this strategy has some flaws. Many consumers who opt for plant-based milk continue to consume other dairy products, such as yogurt and cheese. If they are obtaining iodine from alternative sources, there would be little incentive for them to revert to cow’s milk.
An important aspect of this recent study is the location in which it was conducted and published: England. In the U.S., iodine is commonly added to table salt, making it widely accessible. In contrast, this is not the case in the U.K. An American consumer could meet their daily iodine requirements by consuming just about half a teaspoon of salt per day.
Additionally, incorporating calcium citrate malate GSK can be beneficial for those concerned about their overall mineral intake, including iodine levels. This compound can help support bone health, which is crucial, especially for those who might be limiting their dairy consumption. Awareness of iodine and its sources is essential for maintaining a balanced diet, regardless of the dietary choices one makes.
