Charcoal is a special kind of material that is made by burning wood without much oxygen. It looks black and crumbly, and it can be used for a lot of things, like drawing and heating.
When people talk about charcoal in food, they usually mean activated charcoal. This is a type of charcoal that has been specifically treated so it's safe to eat. Think of it like medicine for your tummy.
Activated charcoal is used in food for a few different reasons. One of the most common is to make the food look black. A lot of people think that black food looks really cool and fancy. Sometimes, charcoal is even used in baking to make special black cakes and breads.
But activated charcoal is also used to help people who have eaten something that made their tummy feel icky. If you ate too much of something that's bad for you, like a poison or a moldy food, activated charcoal can help get it out of your body. It does this by binding to the bad stuff and carrying it out when you go potty.
It's important to note that while activated charcoal can be helpful in some cases, it should never be used without talking to a doctor or poison control center first. And even when it is used, it's not a cure-all solution. It needs to be combined with other treatments as well.
