Celebrity chef Pete Evans is once again in the spotlight, after he was named the winner of this year's Australian Skeptics Bent Spoon award.

The "uncoveted" honour recognises the "perpetrator of the most preposterous piece of paranormal or pseudo-scientific piffle", according to Australian Skeptics Inc.

It was awarded to Evans - who was not there to accept the title - at a gala dinner of the Skeptics National Convention in Brisbane on Saturday night.

Evans is a public supporter of the Paleo diet, which advocates eating only what was available to our ancestors; avoiding food groups like dairy, grains, and any processed food.
