I have a question about the first sentence in the article: "There's a fine line between including foods deemed healthy in your diet and eating nothing but!"
The author admits that there's no such disorder as orthorexia and she can't describe what foods need to be eaten so as not to be orthorexic. Therefore, a parent of a teenager, for example, might just imagine that their child is being too fussy and call a dietition. This article is exactly what I would expect from a dietition: The idea is to find a brand new disorder and some day make it official so that there will be one more problem requiring their services.
