But that's not what I'm talking about here.
Here I'm talking about the knee jerk comfort people have in ascribing a disorder to someone else's dietary concerns or choices, especially in the both traditional and social media.
Just because you might personally find someone else's attention to their diet excessive, that doesn't mean it is to them. Their caring about the choice and types of their foods, so long as it isn't negatively affecting their physical health, mental health, or their quality of life, isn't an eating disorder!
