There are several ways to prevent an iodine deficiency. The best source of iodine is from iodized salt, which is salt that has been fortified with iodine. Other good sources of iodine include seafood, dairy products, and eggs. Vegetables, such as seaweed and spinach, can also contain iodine, but the levels can vary. If iodine deficiency is suspected or diagnosed, a healthcare provider may recommend iodine supplements.

In conclusion, iodine is an essential nutrient that is vital for the proper functioning of the thyroid gland and brain development during pregnancy. Unfortunately, over two billion people have an iodine deficiency, which can lead to several health problems. It’s important to be aware of the signs and symptoms of iodine deficiency and to consume iodine-rich foods or supplements as recommended by a healthcare provider.
