Bromelain

Okay, so imagine pineapple. You know how it's all juicy and sweet? Yum, right? Well, bromelain is actually a special thing that pineapple has in it. It's kind of like a little helper that helps the pineapple break down its own proteins.

But wait, why does pineapple need help breaking down its own proteins? Well, proteins are really important for living things, like animals and plants, but they can also be really hard to break down. That's where bromelain comes in - it helps pineapple break down those proteins so that they can use them for other things.

But that's not all - humans can actually use bromelain too! People have found that bromelain can help with things like swelling and pain, and it's even been used to treat some illnesses. That's why you might see supplements or pills that have "bromelain" on the label - people are trying to use that special pineapple helper to make themselves feel better.

So now you know all about bromelain - it's a special thing that helps pineapple do its job, and people can use it too to help with things like swelling and pain!
