Pineapple

Hey girls, this is gonna sound like a stupid question.. But I've heard about how pineapple may help aid implantation. I don't really like them and have never bought one before in my life (partly because I've got a fixed retainer and I don't want the bits to get stuck!) So I went out today and got myself a pineapple.. Which bit do I eat? I was going to buy precut pieces but I thought maybe it was the core I needed to eat and that was cut out of them. Is it the middle part or the general flesh of the fruit, or should I just eat all of it? How many days should u eat it?
