Can someone give me the details on pineapple core?

What part of the cycle is it recommended to eat it? Any success stories from this? Annnnd probably the dumbest question ever but I’m about to make a smoothie is it ok if I just throw it in there or do you need to actually eat it?

Don’t worry I know pineapples can’t perform miracles but it’s just a piece of fruit, I was gonna eat it anyway and it can’t do any harm (unlike some other things people recommend) so why not 😊 just thought I would ask while I’m at it 😊
