I doubt it as well but Capo this is your issue you know more about it than we do, i really doubt though that your skull would "grow back down" like you say, once your skeletal features are growing to a certain size they don't just go back down because the nutrients are compromised.
Fatty fish like salmon is pretty much all i eat, salmon is low in mercury & high in everything good for us.
Does anyone else think it's pretty different that the only foods high in Vitamins A & D minus nasty vegetables are fatty fish, organ meats, raw milk & dairy products, & sweet potatos?!?!?!
