People fail to realise that a lot of fruit/veg lose its nutrional value minutes after being cut open/processed/juiced/blended/etc. The best way to eat something is in its natural form. If you're going to blend a smoothie for yourself, drink it within 15 minutes before all the vitamins have a chance to disappear.
Addtionally, fruit IS sugar. A lot of people fail to see this. It's natural and contains benefits, but it WILL spike your blood sugar like a piece of white bread. Vegetables don't do this as much, since they contain on the whole much more fibre & vitamins than most fruits. Fruit is good as PART of your 5-a-day and part of a healthy eating plan, but it is not the end-all be-all solution to good nutrition.
That said, I always have an apple in my lunch!
