Reader Marilyn asks about something a relative found on the web:
Rock Salt or Sea Salt
STRESS RELIEF… Is salt bad for hypertensive?
What is bad for hypertension is iodized salt, which is a fake salt. It is made up of only 3 synthetic chemicals, sodium, chloride, iodine. It does not melt in water (glistens like diamonds), does NOT melt in the body, does not melt in the kidneys, gives kidney stones, and raises blood pressure. However, it is the salt favored by the synthetic drug-based doctors who say it is very clean and sanitary, pointing to how white it is and how it glistens like diamonds. The fake salt is man-made in a factory.
The true salt, which comes from the sea and dried under the sun and commonly called rock salt, has 72 natural minerals including natural sodium, chloride, iodine. It melts in water, melts in your body, melts in the kidneys, do not give kidney stones, and best of all brings down blood pressure and stops/prevents muscle cramps, numbness, tingling. If youget muscle cramps in the lower legs at night, just take 1/2 teaspoon of rock salt and a glass of water, and the cramps with its horrific pain will be gone in 5 minutes.
Marilyn was right to be suspicious – this is utter nonsense. Common table salt comes from evaporating seawater (like what happens up at Useless Loop on our west coast). Rock salt comes from mineral deposits and is mined.
It’s the same stuff. It’s possible that the rock salt is higher in other minerals, but that’s the only difference. The chemical behaviour of both types of salt in the body (and everywhere else) is identical.
