Less than 6% of US adults use salt substitutes to control blood pressure. This easy and effective method can help people with high blood pressure. Researchers found that most people still use regular salt despite the benefits.

High blood pressure is a major health issue in the United States. It affects over 122 million adults, leading to more than 130,000 deaths between 2017 and 2020. Diet plays a significant role in developing high blood pressure. Consuming too much sodium and not enough potassium can cause elevated blood pressure.

Salt substitutes are an inexpensive and effective way to control blood pressure. They replace some or all of the sodium in regular salt with potassium. While potassium salt has a similar flavor, it may develop a slightly bitter taste when heated.

Researchers analyzed data from the National Health and Nutrition Examination Survey (NHANES) collected between 2003 and 2020. They found that less than 6% of US adults use salt substitutes, even among those with high blood pressure.

The American Heart Association recommends limiting sodium intake to no more than 2,300 mg per day, with an ideal target of less than 1,500 mg for most adults, especially those with high blood pressure. Reducing intake by 1,000 mg per day can lead to meaningful improvements in blood pressure and overall heart health.

Health care professionals can raise awareness about the safe use of salt substitutes by having conversations with their patients who have persistent or hard-to-manage high blood pressure.
