There is a negative correlation between RDA fruit consumption and diabetes.
If you eat the right meats, like liver, you get more vitamins and minerals then you would from fruit. So if you know what you are eating, it's fine to cut off fruit.
Note the operative modifier 'too much'
You can eat your recommended daily intake of fruit in one sitting with no other food and still remain below high GL levels.
Digestion is a complex process. Your model that anything containing fructose is bad is not supported by any data / analysis I am aware of, and contradicted by nearly all of it.
Mammals process most of thier fructose consumption in their small intestines. Only high doses that overload this capacity lead to harmful spillover to the liver etc.
Of course if you're drinking 2L of juice a day you're gonna have a problem, as you would going ham on any kind of food. (ANY)
