WHO’s New Guidelines on Low-Sodium Salt Substitutes
A step towards better heart health and lower hypertension risks.
Why Reduce Sodium?
Excess sodium = high blood pressure, heart disease, and strokes; 1.9 million deaths annually linked to high sodium intake; WHO recommends <2g sodium/day (5g salt/day).
WHO’s Key Recommendations
Adults can use low-sodium salt substitutes (LSSS) with potassium, but WHO advises against using them in meals for households with members at risk of hyperkalemia (including children and pregnant women)
Scientific Backing
26 randomized controlled trials (RCT) studies show a decrease in systolic blood pressure (SBP) by 4.76 mmHg and diastolic blood pressure (DBP) by 2.43 mmHg, along with a lower risk of stroke and cardiovascular events.
Considerations & Challenges
Concerns include LSSS adoption, cost, awareness, and taste preferences, with more research needed for children and pregnancy safety; the WHO promotes gradual sodium reduction strategies as a solution.
Future Directions
WHO aims for a 30% global sodium reduction by 2030, urging countries to implement sodium policies, with resources like the SHAKE Technical Package for Salt Reduction available.
Final Takeaway
Use less sodium, switch to LSSS where possible, prioritize whole foods rich in potassium (nuts, greens, legumes), and remember, small changes = big health benefits!
