7 foods that were supposed to be incredibly unhealthy, but are actually anything but

They've got some of this right-  milk, eggs, coconut oil, for example.

A couple comments:
Antioxidants have been proven not to help anything and sometimes increase cancer.
Dark Chocolate may be healthful, but it's not because of the antioxidants.   It's also got lots of arginine and promotes oropharygeal microbial activity.

Coffee may have lots of antioxidants, but that's not why it's healthy.   It lowers insulin resistance and has antimicrobial properties which inhibit mouth infections...  if you put sugar in it, you cancel those effects.

Salt also lowers insulin resistance,  that's probably why it's so wonderful on chips and fries.   But helicobacter pylori bacteria in your stomach thrive on that combination.

No, popcorn is not healthy in any way.   And it's not because of the "butter flavored saturated fats".  It's because it's practically 100% carbohydrates that convert to sugar in your mouth.  And that "whole grain husk" is as common an allergen as wheat and soy.   And it tears up your gums.
