Maybe we're too inclined to believe the worst about supermarket food.

How else to explain the reaction to a recent report about honey on the web site Food Safety News? Food Safety News is published by a lawyer who represents plaintiffs in lawsuits against food manufacturers and processors.

Local food is fashionable. Customers are swarming farmers' markets. Organic vegetables sell at a premium. So what's to keep a young, smart, enthusiastic would-be farmer from getting into this business and making a good living?

Allegedly, there's a tsunami washing up on American shores. It originates in Chinese beehives and the American beekeepers who've spotted it are hopping mad.

In 2008, food prices around the world surged and awakened fears – which continue to this day — that the world could re-live the disastrous food shortages of the early 1970s.

Nothing is more basic and simple than food. Yet it comes to us courtesy of a long, complicated supply chain that spans the globe.

That chain delivers food cheaply — but it can break. Four years ago, it blew up in most spectacular fashion, affecting hundreds of millions of people who rely on rice for sustenance. That crash — the great rice crisis of 2008 — was a true disaster for some of the poorest people in Asia and West Africa.

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.
