People do this, and the good ones don't have anything to do with processed food, or if they do, it's entirely superfluous. The Mayo Clinic publishes on this topic and, as I recall, strongly recommends the Mediterranean diet - high in fiber and protein, nutritionally diverse, inclusive of fats and carbohydrates.
I know multiple people that are drinking litres of olive oil daily because of the Mediterranean diet. Because of this critical oversight, I am forced to conclude it's bogus. A real recommendation would address this.
I don't understand anything you're saying. A diet can not compel you to do anything, let alone drink liters of olive oil. I assume this is attempting to parody something about Nova but I frankly can't unpack whatever it's supposed to be.
