Fruits deliver their best nutritional benefits when consumed on an empty stomach, for much of it passes directly onward to the small intestine for digestion. But unless you eat fruit and fruit juice all day, you should limit your consumption to one or two exclusive fruit meals per day. Eating fresh fruits or drinking their juices between starch and protein meals can severely inhibit digestion because the stomach will still be busy working in the starch or protein when the fruit lands there.
