Iodized salt

Iodized salt is a special kind of salt that helps keep our bodies healthy. Iodine is a mineral that our bodies need, but we can't make it ourselves. We have to get it from the foods we eat or from iodized salt.

You know how we need food to help us grow big and strong? Well, our bodies also need iodine to grow and work properly. Iodine helps our thyroid gland make hormones, which help to control lots of important things in our bodies, like our energy levels and how we grow.

Iodized salt is created by adding a little bit of iodine to regular salt. When we use iodized salt in our cooking or sprinkle it on our food, we are helping our bodies get the iodine we need to stay healthy.

In some parts of the world, people don't have enough iodine in their diets, which can lead to problems like goiter (a swelling in the neck) or mental and physical disabilities. Adding iodine to salt has helped to prevent these problems in many places.

So, in short, iodized salt is a type of salt that has a special mineral called iodine added to it, which helps our bodies stay healthy by supporting our thyroid gland.
