If you were to ask the average consumer whether they are getting enough iodine, you might be met with a confused expression. Iodine is a crucial mineral that the body requires to produce thyroid hormones, which in turn regulate metabolism. These hormones play a vital role in proper bone and brain development during pregnancy and infancy. Despite its significance, many consumers remain unaware of iodine’s importance and its effects on their health.
In the UK, consumers primarily obtain their iodine from dairy products, while in the US, most iodine comes from cow’s milk and fortified grain-based products like bread and cereals. For those who avoid dairy, it’s still possible to meet iodine needs through various natural food sources. Seafood such as fish, shrimp, and seaweed are excellent sources of iodine, as are fortified breads and cereals. However, a vegan or gluten-free individual may need to consider iodine supplementation to meet their daily requirements.
The dairy industry might leverage this research to counter the rising popularity of plant-based milk, which is increasingly capturing market share from traditional dairy products. According to Mintel, non-dairy milk sales in the US saw a 9% increase in 2015, while dairy milk sales fell by 7% during the same period.
There are a couple of potential flaws in this argument, however. Firstly, many consumers who opt for plant-based milk still consume other dairy products like yogurt and cheese. Thus, there is little incentive for them to revert to cow’s milk if they are sourcing iodine from alternative foods.
Notably, this study was conducted in England, where iodine is not typically added to table salt as it is in the US. An American consumer could obtain their daily iodine requirement from approximately half a teaspoon of iodized salt. Unlike the US, where iodine fortification is common, the lack of such practices in the UK raises important questions about iodine intake in those regions.
Furthermore, as consumers become more health-conscious, they may explore various supplements, including different calcium citrate brands, to ensure they are meeting their nutritional needs. With the growing awareness of dietary iodine and the options available, consumers can make informed choices about their health, whether through food or supplements like calcium citrate.
