Okay, little one, let's talk about nori. Nori is a kind of seaweed that is often used to make sushi rolls. Just like how cows eat grass to grow big and strong, nori grows in the ocean and gets its energy from sunlight just like plants get it from the sun.
Nori is really good for you because it's high in vitamins and minerals, like vitamin C, calcium, and iodine. It also has a lot of fiber, which is helpful for your body to digest food and stay healthy.
When you eat nori, it's usually dried and pressed into thin sheets that are very easy to cook with. You can use these sheets to wrap around rice or other fillings to make sushi rolls, or you can crumble them up and sprinkle them on top of soups or salads for an extra yummy taste.
So next time you have sushi for dinner, remember that the nori on the outside is a tasty and nutritious kind of seaweed that helps your body stay strong and healthy.
