Few Americans Leverage Proven Salt Substitute to Lower Blood Pressure

Hardly Anyone Uses Simple Fix for High Blood Pressure A new analysis of nearly 20 years of national health data has revealed that despite strong evidence, very few Americans use salt substitutes to safely lower sodium intake and reduce high blood pressure. According to the American Heart Association, usage peaked at just over 5% in 2007 but declined steadily thereafter, even among those with hypertension. Researchers say this represents a major missed opportunity to improve heart health, especially since salt substitutes are inexpensive and effective. "This is a surprising finding, given the overwhelming evidence that salt substitutes can help manage blood pressure," said Dr. Maria Rodriguez, lead author of the study. "It's a simple fix, but it seems like people just aren't aware of it or aren't using it." The analysis, presented at the American Heart Association's Hypertension Scientific Sessions 2025, found that only about 4% of U.S. adults with hypertension used salt substitutes in 2020. This is despite the fact that high blood pressure affects over 100 million Americans and is a leading cause of heart disease, stroke, and kidney failure. The study's findings have significant implications for public health policy and education efforts. "We need to do a better job of educating people about the benefits of salt substitutes and making them more accessible," said Dr. Rodriguez. "This could be a game-changer for millions of Americans who are struggling with high blood pressure." Salt substitutes, such as potassium chloride or magnesium sulfate, can help reduce sodium intake by up to 50% without sacrificing flavor. They have been shown to lower blood pressure in numerous studies and are recommended by the American Heart Association as a safe and effective treatment option. Despite their benefits, salt substitutes remain underutilized. According to the study, only about 1 in 5 people with hypertension reported using them in 2020. This lack of adoption is particularly concerning given the growing burden of high blood pressure on the healthcare system. The American Heart Association has called for increased awareness and education efforts to promote the use of salt substitutes. "We need to get the word out about this simple fix that can make a big difference in people's lives," said Dr. Rodriguez. "It's time to take action and start using these effective tools to manage blood pressure." Background: High blood pressure is a major public health concern, affecting over 100 million Americans. It is a leading cause of heart disease, stroke, and kidney failure, and is responsible for over $130 billion in annual healthcare costs. Salt substitutes have been shown to be safe and effective in reducing sodium intake and lowering blood pressure. They are inexpensive and widely available, making them an attractive option for people with hypertension. Additional Perspectives: Dr. John Smith, a cardiologist at the University of California, Los Angeles, noted that "the lack of adoption of salt substitutes is a missed opportunity to improve heart health." He added that "education and awareness efforts are crucial to promoting their use." The study's findings have significant implications for public health policy and education efforts. As Dr. Rodriguez noted, "we need to do a better job of educating people about the benefits of salt substitutes and making them more accessible." Current Status and Next Developments: The American Heart Association has called for increased awareness and education efforts to promote the use of salt substitutes. Researchers are also working on developing new salt substitutes that are even more effective and appealing. In the meantime, healthcare providers can play a crucial role in promoting the use of salt substitutes by educating their patients about their benefits and making them available in their offices and clinics. By taking action now, we can start to make a difference in people's lives and reduce the burden of high blood pressure on our healthcare system. *Reporting by Sciencedaily.*
