So is fruit really good for you or it is actually bad for you?

I had a long conversation recently with a relative who told me that most fruit is not good for you because of the sugar content.  There’s a lot of conflicting information on the Internet, but this advice from an Icelandic guy seems sensible to me.

So it seems that I can keep eating a banana with my granola cereal, but I have to give up my concentrated orange juice.  What do you think?
