Iodized salt, otherwise known as table salt, is salt mined from underground, while sea salt is obtained by evaporating sea water. By weight, the two types contain the same amount of sodium, but sea salt is sometimes seen as more healthy, because it contains more minerals. However, these are insignificant amounts.
edit Health effects
Iodized salt contains added iodine, a nutrient that helps maintain a healthy thyroid. It is also good for pregnant women.
Some argue that sea salt is more natural and contains more minerals, and so is better for your health. It contains iron, sulfur and magnesium. However, the difference is so minimal to be insignificant.
Iodized salt and sea salt contain the same amount of sodium, and so should not be taken in excess of 1500 milligrams per day.
Sea salt comes in a wide range of varieties at different prices, including Real Salt from Oregon, Fleur de Sel from France, smoked sea salt, Chardonnay sea salt, gray sea salt, flake sea salt, Celtic sea salt, and Pink Himalayan salt.
edit Pros and cons
Iodized salt is significantly cheaper and contains iodine, which is vital for a healthy thyroid. Iodine deficiencies are common in Americans. However, some argue that it has less taste, and dislike that it includes an anti-caking agent, silicon dioxide, which is found in sand.
Sea salt is considered healthier, but is more expensive, and the difference is minimal. It has more texture and taste, but this can be lost when cooking.
edit Taste and usage
Because it goes through less processing, sea salt can be crunchier and sharper in flavor than iodized salt. However, sea salt may lose its flavor and color when cooked or dissolved, and it tastes less “salty” than table salt, due to the presence of extra minerals.
Iodized salt is the preferable salt for baking, as the fine granules quickly dissolve.
Sea salt has become increasingly popular, especially in restaurants, because of its healthy and natural image.
Iodized salt is cheaper than sea salt. While iodized salt may cost $0.49 per pound, sea salt can cost upwards of $0.79. Himalayan sea salt costs $39.40 per pound.
