Pineapple?

Is pineapple just the "popular" trend here right now? Or is it real? Its just on glow that I keep seeing it. Not anywhere else. Is it a myth or is there actually researched science behind this? I love pineapple and I'm down to try anything, its just if this is just a silly trend because everyone else is doing it, it makes me not want to do it a little bit lol.
