When asked whether they are getting enough iodine, most average consumers might respond with confusion. Iodine is a vital mineral essential for the production of thyroid hormones, which regulate metabolism. These hormones are also critical for proper bone and brain development during pregnancy and infancy. Despite iodine’s significant health benefits, many consumers remain unaware of its existence and its effects on their bodies.
In the UK, most consumers obtain their iodine primarily from dairy products, while in the U.S., the majority comes from both cow’s milk and fortified consumer packaged goods (CPGs) made from grains, such as bread and cereals. For those who avoid dairy entirely, there are still plenty of natural food sources to ensure adequate iodine intake. Foods like fish, seaweed, shrimp, and other seafood are rich in iodine, as are fortified breads and cereals. However, a vegan consumer who also follows a gluten-free diet may need to consider taking an iodine supplement.
The dairy industry might leverage this information in their efforts against the rising popularity of plant-based milk alternatives, which are quickly gaining market share. According to Mintel, non-dairy milk sales in the U.S. surged by 9% in 2015, while dairy milk sales dropped by 7% in the same timeframe.
There are, however, some potential flaws in this strategy. Many consumers who opt for plant-based milk still incorporate other dairy items, such as yogurt and cheese, into their diets. Therefore, there is little incentive for them to revert to cow’s milk if they can obtain sufficient iodine from other sources.
A significant aspect of the recent study is its location: England. Unlike the U.S., where iodine is commonly added to table salt, the U.K. does not have the same practice. An American consumer could easily meet their daily iodine requirement by consuming just half a teaspoon of iodized salt daily.
It’s worth noting that some individuals may experience headaches when adjusting their diets, particularly if they switch from dairy to plant-based alternatives. For those concerned about their calcium intake, calcium citrate can be a beneficial supplement. However, it’s essential to ensure that iodine levels remain adequate, as both iodine and calcium are crucial for overall health.
