Salt Substitute Use Low Despite High Blood Pressure
Summary of Article: Salt Substitute Use in US Adults with High Blood Pressure
This article discusses a study examining the use of salt substitutes (products replacing sodium with potassium) among US adults, notably those with high blood pressure. The research was presented at the Scientific Sessions 2025 in Baltimore (September 4-7, 2025).
Key Findings:
Low Usage: Salt substitute use remains very low in the US, peaking at 5.4% in 2013-2014 and falling to 2.5% by 2017-March 2020.
Eligible Population: Even among those eligible to use salt substitutes (normal kidney function, not taking interacting medications), usage is only 2.3-5.1%.
Highest Use in Controlled BP Group: Those with high blood pressure controlled by medication showed the highest usage (3.6-10.5%), followed by those with uncontrolled high blood pressure despite medication (3.7-7.4%).
low Use in Untreated/Normal BP: Usage remained consistently below 5.6% for those with untreated high blood pressure and those with normal blood pressure.
Restaurant Dining: Frequent restaurant dining appeared to correlate with lower salt substitute use, but this wasn’t statistically notable after adjusting for demographics.Significant Context:
High Blood pressure is a Major Problem: 122.4 million (46.7%) US adults have high blood pressure,contributing to over 130,000 deaths. Dietary Factors: High sodium and low potassium intake are risk factors for high blood pressure.
Salt Substitutes are Effective & Inexpensive: They can help control blood pressure, especially in those with challenging-to-treat hypertension.
Caution Advised: Individuals with kidney disease or those taking certain medications should consult a healthcare professional before using salt substitutes due to the risk of dangerously high potassium levels.
American Heart Association Recommendations: Limit sodium intake to no more than 2,300mg per day, ideally less than 1,500mg for most adults.
The study highlights a significant gap between the potential benefits of salt substitutes and thier actual utilization, suggesting a need for increased awareness and discussion between healthcare professionals and their patients.
