The World Health Organization (WHO) has introduced new guidelines encouraging individuals to replace regular salt with lower-sodium salt substitutes (LSSS) at home to help reduce the risk of hypertension and cardiovascular diseases (CVDs).
Why is This Important?
Excessive sodium intake is a well-documented contributor to elevated blood pressure, increasing the risk of heart disease and stroke.
Current global sodium consumption averages more than double the WHO's recommended limit of 2 grams per day, leading to approximately 1.9 million deaths annually.
The new guidelines suggest that adopting LSSS can significantly lower blood pressure and consequently, the risk of cardiovascular events.
What Are Lower-Sodium Salt Substitutes?
LSSS are alternatives to regular salt (sodium chloride), where part of the sodium is replaced with potassium chloride (KCl) or other minerals. This helps reduce sodium intake while maintaining flavor.
Research reviewed by the WHO, including 26 randomized controlled trials (RCTs), has shown that LSSS can help lower blood pressure by reducing both systolic and diastolic levels.
Studies also indicate that replacing regular salt with LSSS can reduce the risk of stroke and cardiovascular-related deaths, making it a valuable tool in preventing heart disease.
Additionally, incorporating LSSS into daily cooking and meals can contribute to an overall reduction in sodium intake, supporting broader public health efforts to combat high blood pressure and related conditions.
WHO Recommendations on Potassium Intake
WHO suggests that adults consume at least 90 mmol/day (about 3,510 mg/day) of potassium. This increase, the WHO claims, will help regulate blood pressure and promote cardiovascular health.
For children, the recommended intake is adjusted based on their energy requirements, ensuring they get the essential nutrients for growth and development.
Potassium offers several key health benefits, including blood pressure regulation. It works to counterbalance the effect of sodium, which is known to raise blood pressure.
The mineral is also important for reducing the risk of stroke and coronary heart disease by supporting healthy heart function.
Additionally, potassium plays a critical role in ensuring proper muscle contractions and nerve signaling, which are essential for daily bodily functions.
*Disclaimer: Individuals with kidney disease or conditions that affect potassium excretion should consult a doctor or healthcare professional before using lower-sodium salt substitutes (LSSS).
