A recent survey conducted by the American Heart Association shows that many Americans are confused about salt options available at grocery stores, but Newsmax Health contributor Dr. David Brownstein says that of the salt choices available — refined vs. unrefined — unrefined salt is the healthiest form.

Unrefined salt, which contains more than 80 minerals, is better for the body compared to refined (regular) table salt, which has all its minerals removed and takes on toxic heavy metals during processing, including aluminum. Refined salt is a “toxic substance” that should be avoided, says Brownstein, editor of “The Natural Way to Health” newsletter.

Unrefined salt, “with its full complement of minerals,” is a better choice than refined sea salt, kosher salt, and salt substitutes, he says. Unrefined salt should be a “vital ingredient in everyone’s diet,” he says.

“It’s a very healthy substance for the body,” Brownstein, author of the book, “Salt Your Way to Health,” says. “The human body was designed to need and acquire unrefined salt.”

With its thicker, larger crystals colored by its mineral content, unrefined salt is available in health food stores. The minerals in it make it a healthy choice for most of his high blood pressure patients, he says.

Studies have shown that when salt is limited, the risk for heart disease, lipid disorders, and diabetes rises, he says.

“The human body needs and utilizes salt,” he says. “We just need the right form of salt in our diet.”

Patients who should avoid unrefined salt are those suffering from kidney failure because they can’t process it, he says.

Brownstein recommends that the average-size adult consume between one-half and one teaspoon of unrefined salt a day.
