The fruit part of the pineapple is very good for digestion, especially when you are eating meat.
It may not give you indegestion but it will surely give you INDIGESTION big time.. so be very careful.
It can give you a rash so people wear gloves when handling them. But you shouldn't eat the skin of the pineapple, chances are where you got the pineapple from uses some sort of pesticide and the skin is covered in it.
It'd probably make you poop a lot. Very fibrous.
