This kind of false attribution is how we got a market full of "low fat" foods packed with sugar. It seems like "don't eat too much sugar" should be a harmless, practical abstraction, but people will go off and eat a diet that still leads to type 2 diabetes while avoiding obvious sugars. And missing non-obvious ones. For example: A "healthy" serving of plain corn flakes with a serving of plain milk has lots of sugar in it. Foods can have low added sugar, or low some-kind-of sugar, and still lead to type 2 diabetes. Focusing on sugar will lead to the same health disaster that came from focusing on salt or fat.
