The organisation's federal vice-president, Tony Bartone, went even further, accusing Evans of "wilful arrogance" in "mischievously questioning medical advice".
Speaking on Sunday Night, Evans dismissed criticism of his paleo diet, saying: "What do you need a qualification for to talk common sense? That's what I say to it".
His most headline-making views have been about the what to feed babies (the "bone broth" debacle) and whether he uses sunscreen.
So what should you feed babies, according to Paleo Pete? "Breast milk, breast milk, breast milk, breast milk. I don't know how many more times I have to say it," Evans said, when asked to clarify comments he made in one of his books about feeding bubs "bone broth".
Evans also insisted he does wear sunscreen ... just a "non-toxic" one.
"I did say if we go out in the middle of the day, for long periods of time, then I use a non-toxic sunscreen," Evans told Sunday Night.
"A lot of sunscreens, as I said, are full of toxic chemicals you just would not put on your face or your children's faces. I never said 'don't use sunscreen'.
"Make sure you choose one that is the least toxic."
Speaking to Sunday Night, he also criticised the use of fluoride in water and rejected the health benefits of dairy.
"The calcium dairy myth is the best piece of marketing I've ever heard," Evans told the programme.
When questioned by Sunday Night journo Alex Cullen about the sources of his claims, Evans responded bluntly: "You're a journalist, you should be doing the research yourself."
Meantime, Evans also dismissed reports of a rift with his My Kitchen Rules cast mate, Manu Feildel, saying they're "best mates".
"Manu and I are best mates, yes. Hand on my heart. And he would say exactly the same thing," Evans said.
