  • Sea salt is made by evaporating seawater to leave behind trace minerals and elements, which then add various flavors and colors to the salt, depending on its source location. In general, it is not highly processed.
  • Table salt is mined from underground deposits and processed to eliminate minerals, which are seen as contaminants by some consumers. In contrast to sea salt, it usually contains a manufactured (synthetic) anti-clumping agent such as sodium aluminosilicate. It may be found in either a fine or a coarse (Kosher salt) version.
  • Both kinds of salt are used to enhance flavors in cooking. Some people taste a difference between the two. Taste differences are most likely due to the variety of minerals specific to a sea salt’s region of origin. Sea salt may be beneficial if you enjoy the taste of sea salt better, and, so, end up using less.


  • Some people have what is called “salt-sensitive” hypertension. This means that their elevated blood pressures are caused, at least in part, by the amount of salt in their diet. Blood pressure usually improves by decreasing the amount of salt (regardless of type) in the diet.
  • Sea salt is no better health-wise, and actually may be worse for you than table salt.
  • Table salt is iodized, which means that iodine has been added to prevent goiters (large thyroid gland tumors). Now understood to be caused by an iodine deficiency, goiters were once much more common in the population.


DOSAGE:No more than 1500 mg a day for those with hypertension and other risk factors. Up to 2300 mg a day for others.

CONCLUSION:We conclude that sea salt is a safe product. If you prefer the taste of sea salt, use it in moderation. If you happen to know that you have salt-sensitive hypertension, it is unlikely that you will tolerate sea salt any better than table salt.
