I'm not trying to lose weight, and I've never knowingly bought a specialty orange. Sugar is in basically every plant food, and saying "give up all sugar" means going carnivore plus eggs and a select few dairy products.
The point here is saying "fruit is healthy" is just not true in any sort of black and white sense. Someone can easily get fat and be unhealthy by eating fruits with lots of sugar, and if they are juicing them, even more so.
