What do you do with pineapple core?

Just bought a pineapple for the first time. Checked a few videos and posts on internet to see how I am supposed to cut it up, everyone said to throw the core away or use it in a smoothie at best. Even my mom said to throw it away.

Anyway, I tried to eat a small amount of it, and then ate the entire core. It's pretty edible, feels like throwing out pizza crust.

Much more chewable than celeriac. Though I would label it as "Dental floss mandatory" type of food, but so is anything with poppy seeds.

So how do you use it? Do you eat it, throw it out, something else?
