Dude, “orthorexia” was a thing that was baselessly made up. It doesn’t exist.

It’s not hard to just leave bananas out of recipes, at least for me, it doesn’t feel like a loss in the first place. Just more room for better things.

Spinach is fine, the oxalates bind the spinach’s own nutrients. The only issue there is a higher risk of kidney stones, which is easily avoided by eating a balanced variety of mixed greens regularly instead of any single one.
