The American Heart Association conducted a survey in 2011 stating that 61% mistakenly said sea salt is lower in sodium and a better alternative to table salt. The truth is though most salts, such as sea salt, table salt, kosher salt, and Himalayan pink salt, all have about 40% sodium.
Do you know why most labels claim to have less sodium? It is because of the volume of the salt itself; the smaller salt crystals are, the more of them can fit onto a measuring spoon. For example, table salt may have about 2300mg of sodium in a teaspoon, but there are about 2000mg of sodium per teaspoon if you are using sea salt and pink Himalayan salt has about 1700 mg of sodium per teaspoon. All their volumes are different because of the size of the salt crystals.
Some companies even claim that certain salts consist of special minerals. Although, this is not true because the amount of minerals noted are exceptionally low. You can, however, eat minerals such as iron and magnesium in these salts. But by eating healthier, you can consume these kinds of minerals through eating foods such as vegetables, fruits, whole grains, fat-free or low-fat dairy, lean meats, poultry, fish and legumes. Eating the healthiest foods can help you acquire all the energy and minerals you need.
