Quick question: Are vegetables less nutritious than they used to be?

You're free to argue about this, because scientists haven't managed to come up with a clear answer.

There's some new data out this week in the journal Crop Science, and at least for broccoli, the answer seems to be no. But keep reading, because the story gets a little more complicated.
