Iodine fuels body and cognitive functions.
Iodine is an essential nutrient that the human body needs to function properly. There are a variety of food sources that provide iodine, including seafood, dairy products, and some grains. Iodine plays a critical role in the production of thyroid hormones, which regulate metabolism and support cognitive development.
Consuming the recommended daily amount of iodine is particularly important for pregnant women and young children. A deficiency during pregnancy can lead to complications such as miscarriage, stillbirth, and congenital abnormalities. In children, iodine deficiency can cause intellectual impairments and delay physical development.
While some people may be able to obtain iodine through fortified salt, it’s important to note that not all salt is iodized. Therefore, it’s important to pay attention to the food sources that naturally contain iodine, such as seafood and dairy, and consider supplementation if necessary. Incorporating these foods into your diet can help ensure that you receive the necessary amount for optimal health.
Adults need 150 micrograms/day, while pregnant/breastfeeding women need 220-290 micrograms/day. Children/adolescents require 90-150 micrograms/day depending on their age.
