From the moment it was touted as a Paleo baby diet book there were concerns over its safety but it seems now these very real fears may finally been acted upon.

The Australian Women’s Weekly has reported that publishers Pan Macmillan have held back the upcoming release of Bubba Yum Yum: The Paleo Way – after health officials expressed concerns that a baby might die if fed some of the recipes.

“In my view, there’s a very real possibility that a baby may die if this book goes ahead,” Professor Heather Yeatman, president of the Public Health Association of Australia, has told The Weekly.

The Federal Department of Health has been reportedly scrutinizing the recipes.

The cause of concern is the high levels of vitamin A in a DIY formula recipe which “contains more than ten times the safe maximum daily intake of vitamin A for babies and inadequate levels of other nutrients.”

The formula, made from bone broth includes ingredients like chicken liver, oils and a probiotic supplement which “could potentially cause a vitamin A overdose in infants, the symptoms of which include loss of appetite, dry skin, hair loss, bone pain, fissures in the corners of the mouth and failure to thrive,” says The Weekly.
