Agreed, excepting grapes, as long as you are eating fruit itself, not fruit juice, pulp, puree or something else made from fruit.

Fruits are MUCH better than nuts thanks to their lower caloric density. but it's still easy to mindlessly eat hundreds of calories of fruit if you're not careful.

Given that even a hundred calories of surplus a day will certainly make you fat over time... basically any mindless eating is dangerous, in my experience.
