My Kitchen Rules Chef Pete Evans has told his 1.5 million Facebook followers that the act of wearing sunscreen and sunbathing for hours is a "recipe for disaster".

In a 'Question and Answer' post on his Facebook page, a commenter asked the surfing enthusiast and television chef what he used as sunscreen.

Pete Evans: great teeth and some good advice.

Mr Evans said he wore "generally nothing", and said his year-long tan and the short amount of time he spends in the sun keeps him safe.

"The silly thing is people put on normal chemical sunscreen then lay out in the sun for hours on end and think that they are safe because they have covered themselves in poisonous chemicals which is a recipe for disaster," wrote Mr Evans.
