it looks like her new 'obsession' is being healthy and happy  Personally, I call that being psychologically healthy. It's unfortunate that it can be a very difficult "obsession" for patients/clientele to develop, though. I understand why it makes you anxious, though. It's not uncommon for ED patients - those with anorexia, especially - to have a lot of knowledge about nutrition. I'd consider it a mild warning sign, too.
