Wikipedia's first describes this as a proposed eating disorder characterized by an excessive preoccupation with eating healthy food.
People become obsessive about all manner of things. Educated approaches to food intake are a whole different category and shouldn't be vilified or scoffed at.
I'm with you, Keesha. Our bodies tell us what fuel works best (and that sure changes over time, doesn't it!?!).
These days my diet is overall 95% (or more) plant based, low oil, very few processed foods (some vegan ice cream and an occasional Beyond Burger). At most one meal a week contains cheese, more rarely a bit of shellfish. I also avoid simple carbs.
My body and conscience feel better with that eating plan. Other people make their own choices.
