When you ask the average consumer if they’re getting enough iodine, you’re likely to receive a confused expression in response. Iodine is an essential mineral that the body requires to produce thyroid hormones, which regulate metabolism. These hormones are also vital for proper bone and brain development during pregnancy and infancy. Despite its significant role in overall health, many people are unfamiliar with what iodine is and how it affects their bodies.
In the UK, most consumers obtain their iodine primarily from dairy products, while in the U.S., it comes mainly from cow’s milk and fortified consumer packaged goods (CPGs) such as bread and cereals. A consumer who avoids dairy completely can still meet their iodine needs through other natural food sources. Foods like fish, seaweed, shrimp, and various seafood are rich in iodine, along with fortified breads and cereals. However, those who follow a vegan and gluten-free diet might need to consider an iodine supplement.
The dairy industry may attempt to leverage this study to bolster its case against plant-based milk, which is rapidly gaining ground against traditional dairy products. According to Mintel, U.S. sales of non-dairy milk rose by 9% in 2015, while dairy milk sales fell by 7% in the same timeframe. Nonetheless, there are several flaws in this argument. Many consumers who opt for plant-based milk still consume other dairy items, such as yogurt and cheese, so there’s little incentive for them to revert to cow’s milk if they can source iodine from other foods.
A crucial detail from the recent study is its location: England. While iodine is commonly added to table salt in the U.S. and is easily accessible, this is not the case in the UK. An American consumer could obtain their entire daily iodine requirement from just about half a teaspoon of iodine-fortified salt.
Furthermore, when considering the nutritional benefits, one might also ponder the comparison of algae calcium vs calcium citrate. Both forms provide essential minerals but come from different sources and have varying absorption rates. Incorporating algae calcium into one’s diet could offer an alternative for those who are concerned about their calcium intake, especially if they are also monitoring their iodine levels. As consumers navigate their dietary choices, understanding these nuances becomes increasingly important for maintaining overall health.
