Celebrity chef Pete Evans has lost yet another profitable deal after being dropped as a celebrity ambassador by the national salad chain, Sumo Salad. The food chain are strongly denying that this move is related to Evans' recent paleo controversies, and maintains that the decision to not renew his two-year contract was made a long time ago. This comes at the same time that Evans announced that his disputed baby cookbook 'Bubba Yum Yum: The Paleo Way' will become a self-published digital book to be released this month.

'I think often when you’re trying to make a difference you have to be a bit radical and stand out. We’ve always been very supportive of Pete and we’re happy with that,' Orrenius said. Pete Evans' paleo cookbook for infants  had been delayed over grave concerns about a recipe for baby formula made from liver and bone broth. 'In my view, there's a very real possibility that a baby may die if this book goes ahead,' said Professor Heather Yeatman, president of the Public Health Association of Australia. However, the book is reportedly set for release online amidst the controversy. 'We now know that [Bubba Yum Yum] will be released by the end of the month,' Evans posted on his Facebook on Thursday afternoon.
