The Salt Wars

Salt is a magical substance. It reduces bitterness, enhances
sweetness, boosts flavor, and preserves perishable foods. Without
it, we would die: the human body can’t make sodium, but our nerves
and muscles don’t work without it. It was considered rare until
quite recently, so it’s hardly surprising that, throughout history,
salt has been the engine behind empires and revolutions. Today,
there’s a new battle in the salt wars, between those who think that
we eat too much of it and it’s killing us—and those who think most
of us are just fine. Join us for a serving of salt, seasoned
with science, history, and a little politics.   Learn
