See but here is where I get confused. The advice you are saying is to "completely eliminate added sugar" but then you say it's due to fiber, nutrients, and hard to overeat.

I'm not trying to be pedantic, but people who go to the level of "eliminate sugar completely" are usually pretty knowledgeable, so I'm trying to get into the specifics.

On a societal level the idea of reducing sugar is a positive one, but trying to eliminate sugar is the wrong idea. As far as I know eating a bowl of greek yogurt with homemade granola, raspberries, and maple syrup (or even some powdered cane sugar, which I don't use), has substantially more fiber, less sugar, and more nutrient balance (and less likely to overeat) than sitting down and eating a mango, yet under the current advice trend I'm doing it wrong by "adding sugar" to the greek yogurt, and I'm totally fine to eat the mango since the sugar was in there by default.

Given that factory farmed fruit has been having increasing amounts of sugar over time it's really a lot more about nutrients, fiber, and sugar, than it is about blanket rules.

Saying "no added sugar" is a positive high level societal rule, like "eat 3-5 servings of vegetables and fruit a day" but if you get into absolute rules among nutritionally educated people, things like "no added sugar" don't really track.

you can overeat fruit and vegetables and not all fruit is the same. Bananas vs kale is a good example. You should eat more kale, but you should avoid bananas unless they’re green (lots of resistant starch)
