Sea Salt: Any evidence its better than regular salt?

I personally use Coarse Sea Salt on most of my foods simply because it tastes better, but I’ve also heard it’s supposed to have some healthy properties.

Is there any difference between pure sea salt and regular sea salt in that domain?

I agree that sea salt tastes better but perhaps it is not always the best option.

Sometimes a bit of normal old table salt is a good thing.

Sea salt is going to have trace minerals that are not present in pure sodium chloride. That’s probably better for your health, even though most health claims for “natural” foods and nutritional supplements are romantic hogwash.

In terms of health effects, there’s no real difference between sea salt and table salt. I’m trying to find a cite, but my food reference books are unavailable at the moment and a Google search is turning up a lot of useless info. This is the best I’ve got at the moment:

This would depend on your diet. Nearly all processed foods are seasoned with iodized salt, including canned vegetables, soups, meats, etc., as are most frozen foods, potato chips, canned nuts, etc. In addition, if you salt your food in a restaurant, you’re using iodized salt in most cases; same thing goes for those little packets you use in the movie theater and at McD’s. In the US, we get more damn salt than we need, and certainly enough iodine, without adding it at the table. I use sea salt and kosher salt exclusively at home.

On some cooking boards, people have been known to claim that the iodine in table salt gives an off flavor. I have never noticed this. YMMV.
I use kosher or sea salt for the simple reason is that the flakes of the salt tend to stick to the food, rather than rolling off like table salt will.

For people who eat a balanced diet with plenty of fruit, vegtables and seafood, goitre shouldn’t really be a problem.

And Jeffery Steingarten claims that, for most sea-salts on the market, the purported taste difference is purely psychological. In a blind taste test between pure NaCl and many different brands of sea salt, he found very few which tasters could reliably distinguish.

Right- for all intents and purposes, sea salt (or Kosher salt) is NaCl, just as rock salt is. There is no difference in taste or trace minerals. It is unlikely one can distiguise the Iodine, either.

“But wait” you say- “I am sure it tastes different!” Perhaps- when sprinkled on food (rather than added for cooking) the shape of the grains seem to impact your tongue in a different way, imparting it’s saltiness in a different way. Rock salt ground into the same shape will taste the same, I assume you.

However, there is a rather rare product called “grey salt”- which does have trace minerals* and does taste different. It is generally imported from France and has to be specially harvested in order to be imported. It is more or less sea-water that has been evaporated. Many chefs rave about it. I have a small tin- 'Sea Star" brand. Howeve, in cooking, I can see no difference- just when sprinkled- and it seems to only taste better on meat. And of course- it does have Iodine in it (.00007%)

:smack:

For me, there is a very distinct chemical taste to iodized salt. In a blind test, our entire cooking class rejected the Morton’s sample as the worst tasting salt.

That is possible, especially when not used in cooking. But I doubt if many could tell sea, rock or kosher apart- after you ground down each with a morta and pestle to the same consistency.

However, “grey salt” does contain Iodine, and is used by many top French Chefs.
