Advise on fruit

I know my diet is 3 fat 5 sugar, but i bought grape fruits not realizing they have 11 sugars should i throw them away or what?

Have you tried grapes? Do they make you dump? I was told No grapes because the skin may block our opening to the intestines; but yet I see it on our list of acceptable fruits. They say that bananas have lots of sugars and that is also on the list. I guess if in doubt, throw it out.
