I barely eat fruit, prefer savoury foods usually, I do like canned pineapple in juice (btw pineapple - though only fresh I suspect - has an enzyme called
bromelain which may be an anti-inflammatory, and among more alternative-health type sites is sometimes suggested as part of an anti-cancer diet) and frozen blueberries sometimes, but I tend to eat a ton of veg instead.
Fruit in general will be the kind of thing I add when I get to maintence, for taste alone, eg a banana a day or in winter I like canned prunes in Ready Brek, with a pinch each of cinnamon and powdered ginger, and half a banana sliced in... <drools on keyboard!>
I'm not into the whole "paleo diet" thing but on the other hand I'm pretty sure our ancestors didn't have exotic fruit 12 months of the year on demand, so I doubt it's totally essential to health to suddenly do that, especially swilling large amounts of denatured citrus juices, which are adjusted with chemical additives (extracted from fruit, hence no need to put them on the label) to make every glass of Tropicana or store's own juice taste EXACTLY like every other one...
