Cutting up foods in advance?

I have a hard time getting up early. I try to drink a green lemonade every day for breakfast (as Natalia Rose describes in her book) and I always prepare it fresh, as she says vitamins get lost so quickley you should not prepare it the night before.

Now does the same thing apply to cutting up fruit? Because I like to take some kind of fresh fruit salad with me to work... do you think I could do this the night before or rather not?
