When inquiring about the therapeutic effects of ferrous sulfate, the average consumer might respond with confusion regarding their iodine intake. Iodine is a vital mineral necessary for the production of thyroid hormones, which regulate metabolism. These hormones are also essential for proper bone and brain development during pregnancy and infancy. Despite iodine’s crucial role in health, many individuals remain unaware of its significance and influence on their bodies.
In the UK, consumers primarily obtain their iodine from dairy products, while in the U.S., the majority comes from cow’s milk and fortified consumer packaged goods (CPGs) derived from grains, such as breads and cereals. For those avoiding dairy altogether, sufficient iodine can still be sourced from other natural foods. Fish, seaweed, shrimp, and various seafood options are abundant in iodine, in addition to fortified breads and cereals. However, a vegan and gluten-free consumer might need to contemplate taking an iodine supplement to meet their needs.
The dairy industry may attempt to leverage this research to strengthen its position against the rising popularity of plant-based milks, which are rapidly gaining market share from traditional dairy products. According to Mintel, U.S. sales of non-dairy milk increased by 9% in 2015, while dairy milk sales saw a 7% decline during the same timeframe.
There are a few potential flaws in this approach, though. Many consumers who opt for plant-based milk still incorporate other dairy items, such as yogurt and cheese, into their diets. Thus, there’s little incentive for them to revert to cow’s milk if they can obtain iodine from alternative sources.
A significant aspect of this recent study is its geographical context: England. While iodine is commonly added to table salt in the U.S. and is widely accessible, this is not the case in the UK. An American consumer could meet their daily iodine needs with approximately half a teaspoon of salt.
Additionally, for individuals looking to enhance their nutrient intake, incorporating supplements like Citracal calcium citrate with vitamin D slow release can be beneficial, especially for those who may not get enough calcium and vitamin D from their diet. This supplement could play a supportive role in overall health, particularly for those limiting dairy and seeking alternative sources of essential nutrients.
