Too many salt options? Based on health properties alone, all salt is similar

Have you stood in the seasonings aisle of your local grocery store lately looking for salt and found yourself face to face with more salt choices than you knew existed? There’s the old standby, standard table salt. Or maybe sea salt in a fancy grinder? Light pink Himalayan salt is pretty. And it sounds healthy — is it? 

Salt is in nearly everything we eat, and most recipes call for salt. So how can you know which to choose? 

In the U.S., most people’s dietary sodium comes from processed foods and eating out at restaurants. If you’re aiming to cut back on your sodium intake, experts recommend you start by making more meals at home. 

Thanks to social media buzz, you might have heard that some salts are healthier or gotten the impression iodized salt is overrated, but these salts aren’t so nutritionally different from your average table salt. 

That means you probably don’t have to shell out extra money to arm yourself with a wide array of fancy salts. There’s no sign they’ll improve your heart health or overall wellness. But, if you’re looking to explore the world of salts, they could elevate your home cooking. 

Here are some things to keep in mind.

First, a word about sodium and its risks

People sometimes think salt and sodium are the same thing. But sodium chloride is salt’s largest component, no matter what kind. 

For years, U.S. health officials have recommended that most adults consume less than 2,300 mg of sodium daily. That’s less than about 1 teaspoon of table salt. A single teaspoon of other salt types may contain a little less sodium than that, partly because of grain size. 

Overall, most people in the U.S. consume more sodium each day than public health officials recommend. 

Some research shows that higher sodium intake is linked to health problems such as kidney disease and higher cardiovascular risk. 

Table salt

This is the most widely used salt. It’s the fine white grains you find in many salt shakers. It is typically mined from underground salt rock deposits. Standard table salt, which is processed to remove other nutrients, is about 40% sodium and 60% chloride. 

The other thing you’ll sometimes encounter when reading the food label on table salt falls into a category of ingredients known as anti-caking agents. These ingredients are sometimes added in extremely small amounts to prevent foods such as salt or flour from clumping together.

Iodized salt 

If salt is iodized, it means iodine was added during the manufacturing process. Your body doesn’t make iodine, but it needs the nutrient to make thyroid hormones that control metabolism and other functions. That’s why iodized salt can be a valuable, reliable source of iodine — something you probably need if you don’t often eat other sources of iodine such as seaweed or seafood. 

Different salts can be iodized. Table salt is often iodized, and you can buy iodized sea salt or iodized Himalayan salt. 

To some sensitive palates, iodine can have a slightly bitter or metallic taste.

Kosher salt

Kosher salt is sodium chloride that has a coarser, more uneven grain than table salt. Similar to table salt, it is mined from salt deposits. Unlike table salt, there usually aren’t anti-caking agents or iodine in kosher salt, so some people prefer it for a purer flavor. 

Chefs often prefer using kosher salt because it’s easy to pinch and distribute — and because it doesn’t include components like iodine that can introduce bitter or metallic notes to a dish. Different brands of kosher salt can vary when it comes to density or grain size, so a recipe might even call for a particular brand. 

It’s worth noting: Not all kosher salt meets the requirements of Jewish dietary laws. If you’re looking for true kosher salt, you’ll need to buy a package labeled "kosher-certified."

Sea salt 

Sea salt is produced by evaporating sea water. Some people promote sea salt as healthier than table salt, but it is about 90% sodium chloride and both salts have essentially the same nutritional value and amount of sodium by weight. Sea salt crystals are often larger than table salt grains, though, so a teaspoon of sea salt might contain less sodium. 

Sea salt is less processed than table salt, which means it can contain trace amounts of more minerals than table salt. Magnesium, calcium and potassium are often found in sea salt. Ultimately, the minerals present depend on where a company got the water that was evaporated to make its sea salt — something that can also affect the salt’s taste or color. China is the world’s largest salt producer. 

Sea salt is often coarser, has larger crystals and tastes stronger than table salt, so it might be preferred if you’re hoping to add some texture to a dish or want a particular flavor.

Himalayan salt 

This light pink salt is mined in Pakistan near, you guessed it, the Himalayas. It is extracted from the mine by hand and undergoes limited processing, meaning it retains other minerals and elements such as the iron oxide that give it its pink color. 

Different brands of Himalayan salt can contain different amounts of sodium. Along with the standard sodium chloride and iron oxide, Himalayan salt often includes minerals such as calcium, iron, potassium, magnesium and zinc. 

Overall, the minerals sometimes found in Himalayan salt can be beneficial to a person’s health, but salt isn’t the best way to get them into your diet. A 2020 Australian study found that these minerals appear in Himalayan salt in such small quantities that a person would need to consume too much — about 6 teaspoons each day — for the salt to significantly add to a person’s overall nutrient intake. That much salt is "a level that would provide excessive sodium and potential harmful effects," researchers wrote.

Research has not proved that consuming this pink-tinted salt is healthier or offers particular benefits that other salts cannot. 

Himalayan salt is a popular finishing salt — added right before you eat your food. Its larger grains add texture.
