The New American Revolution

If it's true that we are what we eat, does the same apply to nations? In other words, if a nation's dietary habits start changing, does that tell us something about the nation itself?

Perhaps I should explain, since food is not a subject I often write about. According to an article in the Wall Street Journal this week, the U.S. is currently experiencing a booming demand for -- wait for it -- hummus.

This strikes me as interesting for a couple of reasons. First, I eat tons of the stuff myself, in the perhaps mistaken belief that as my snack of choice, it is less likely to clog up my arteries or further expand my waistline than, for example, cheese.

Second, I associate hummus with the Middle East, especially Lebanon, although I know that as soon as I say that, I enrage millions of Israelis who jealously regard it as their own national dish. And there's not much that comes from the Middle East these days that Americans welcome into their homes or refridgerators.

(Here's something I didn't know: apparently, one reason why hummus is so popular in Israel is that it's made from ingredients that under Jewish dietary laws can be eaten with both meat and dairy products. Which is, of course, extremely useful.)

Now, I know the U.S. well enough to know that not every American exists solely on a diet of burgers, fries, pizzas and giant buckets of sugar-laden carbonated beverages. On the other hand, many do, so if they're turning to dainty little dips of hummus as their lunch of choice, well, what should we make of it? (And here's something else I didn't know: one of America's biggest hummus makers is half-owned by Pepsi Co. Hmm ...)

So here are some numbers, courtesy of that same article in the Wall Street Journal. Last year's U.S. harvest of chickpeas, the main ingredient in hummus, totalled a record 332 million pounds, up by more than 50 percent from 2011. This year, American farmers are expected to plant a record 214,300 acres of chickpeas, five times as much as a decade ago, to meet demand not only from domestic consumers but also from Spain, Turkey and Pakistan.

And how's this for yet another intriguing fact? In Virginia, state officials are encouraging local farmers to plant chickpeas to take the place of tobacco, for which the market has shrunk dramatically due to falling cigarette sales. So it seems Americans are now dipping instead of puffing.

Ah, if only. In fact, those impressive-looking figures start to look a lot less impressive as soon as you compare them with other foodstuffs. Meat, for example? U.S. consumption last year: 52 billion pounds, equal to about 270 pounds per person. That's the highest rate of meat consumption per person on earth, with the one exception of Luxembourg -- and I have no idea how much hummus Luxembourgers eat.

But I am not to be deflected from my vision of America as an emerging nation of hummus-dippers. For surely such a nation would be a gentler nation, more understanding of others, more tolerant of cultural and dietary diversity. Could a nation of hummus-lovers also be a nation of gun-lovers? Surely not.

And even if there is still a long way to go before the falafel takes the place of the burger in American dietary mythology, in the words of the old Chinese saying: "A journey of 1,000 miles begins with a single step." So I can dream.

As Martin Luther King would never have said, and I mean no disrespect when I parody him: I have a dream that my four children will one day live in a nation where they will not be judged by the colour of their skin but by what they put on their plates.

"And when this happens, when we allow freedom to ring ... we will be able to speed up that day when all of God's children ... will be able to join hands and sing in the words of the old Negro spiritual, "Free at last! Free at last! Thank God Almighty, we are free at last ... to eat hummus."
