Raising the World’s I.Q.

Travelers to Africa and Asia all have their favorite forms of foreign aid to “make a difference.” One of mine is a miracle substance that is cheap and actually makes people smarter.

Unfortunately, it has one appalling side effect. No, it doesn’t make you sterile, but it is just about the least sexy substance in the world. Indeed, because it’s so numbingly boring, few people pay attention to it or invest in it. (Or dare write about it!)

It’s iodized salt.

Yet the strategy hasn’t been fully put in place, partly because micronutrients have zero glamour. There are no starlets embracing iodine. And guess which country has taken the lead in this area by sponsoring the Micronutrient Initiative? Hint: It’s earnest and dull, just like micronutrients themselves.

Ta-da — Canada!

(Years ago, New Republic magazine held a contest for the most boring headline ever. The benchmark was from a Times Op-Ed column — not mine — that read “Worthwhile Canadian Initiative.” Alas, that’s salt iodization!)

Pakistan is typical of the challenges. Until recently, 6 in 10 Pakistani schoolchildren were iodine-deficient. Iodine just wasn’t on anyone’s mind.

Indeed, the problem used to be widespread in the Alps. The word “cretin” is believed to come from a mountain dialect of French, apparently because iodine deficiency in the Alps produced so many cretins. The problem ended when food was brought in from elsewhere and salt was iodized.

There is talk that President-elect Barack Obama may reorganize the American aid apparatus, perhaps turning it into a cabinet department. There are many competing good causes — I’m a huge believer in spending more on education and maternal health, in particular — but there may be no investment that gets more bang for the buck than micronutrients.

So, yes, salt iodization is boring. But if we can add 1 billion points to the global I.Q., then let’s lend strong American support — to a worthwhile Canadian initiative.
