Another important thing I didn't know

From the Lancet via Nicholas Kristof:

Iodine deficiency is the most common cause of preventable mental impairment worldwide.

Other micronutrients matter, too, and are similarly as cheap as dirt.

There is a huge amount of knowledge loose in the world. Why is it that news outlets provide so little of it? Because, as Kristof says, "There are no starlets embracing iodine"?

Something tells me that other cultures are not so stuck on entertainment as we are. But it is what it is, hence my illustration.
