AIIMS And Public Health Experts Endorse Low-Sodium Salt To Combat India’s Hypertension Crisis

With hypertension affecting over 28% of Indian adults, experts are urging households to replace regular table salt with low-sodium alternatives. This simple dietary shift could significantly reduce cardiovascular risk and prevent thousands of deaths annually.  

Why Low-Sodium Salt Matters  

Low-sodium salt substitutes (LSSS) typically contain 70–75% sodium chloride and 25–30% potassium chloride. This composition lowers sodium intake while boosting potassium, which helps counteract sodium’s harmful effects on blood pressure.  

Evidence From Research  

Clinical trials in India and China show measurable benefits. A 2021 Indian study reported a 4.6 mm Hg reduction in systolic blood pressure among hypertensive adults using LSSS. A large Chinese trial demonstrated reductions in stroke (14%), cardiovascular events (13%), and overall mortality (12%).  

Public Health Strategy  

Experts recommend integrating LSSS into national nutrition programs such as school mid-day meals, ICDS, PDS rations, and hospital kitchens. Reformulating packaged foods and restaurant meals with potassium salts is also advised to normalize use across society.  

Safety Considerations  

While generally safe, caution is required for individuals with advanced kidney disease or high potassium levels. Experts emphasize that nearly 90% of the population can safely benefit with proper screening and awareness.  

Key Highlights  

• Indians consume 8–11 grams of salt daily, double WHO’s limit  
• Low-sodium salt substitutes reduce blood pressure and cardiovascular risk  
• AIIMS calls LSSS a “dietary vaccine” for hypertension  
• Trials show reductions in stroke, heart disease, and mortality  
• Public programs urged to adopt potassium-enriched salts
