I have never in my life heard that before. Personally, it sounds to me like someone with not enough to do made that up just to have something to do. That sounds ridiculous. If it were true, I'm sure something would've been said about it already like waaaaaaay long ago.
You should ask a professional. I don't know what kind of professional, maybe a nutritionist, organic farmer, any kind of farmer. Maybe a peanut farmer website xD

Good luck! I'm going to go look up some stuff to see if I can help here some.
