Depends on how much you eat - eating 7 apples a day & no other superfree is not great. General nutritional advice is that 2/3rds of your fruit & veg intake should be veg. You aren't necessarily going to get fat eating too much fruit, but as you get closer to target you could see a reduction in your losses.
However, if you are choosing fruit over a chocolate bar/biscuit to get a sugar fix, carry on - you're making a better choice after all.
As said before, variety is best - try to have a variety of colours as this will help make sure you get all the vits you need
