I frequently speak to people that have the misconception sea salt is better for your heart health than regular table salt. From a chemical and nutritional standpoint, both are sodium chloride and you want to limit your sodium intake to 2300 mg (~1 tsp of table salt) or less to promote blood pressure control.
If you use kosher salt, which has larger crystals, you benefit because less salt “fits” in one teaspoon due to the larger crystal size. A teaspoon of kosher salt provides about 1900 mg sodium. Sea salt is available in this larger crystal form, also.
