Do they not teach you about macronutrients in highschool?

I think nutrition is one of the earliest things you figure out that it depends and nobody really knows what their talking about. My mother and wife have a lot of opinions about nutrition that are obviously unscientific, situational and anecdotal.

There is more nuance involved. What kind of fat? What kind of diet? Calorie surplus? What about salt? What kind of metabolism do you have?

It is just impossible to make blanket statements like eat fat, do not eat fat, eat sugar, do not eat sugar. It's your own responsibility to figure it out instead of being told what to do.
