Salt Reduction Efforts in India
Recent studies reveal excessive salt intake is driving a silent health crisis in India. High salt consumption increases risks of hypertension, stroke, heart disease, and kidney disorders. Scientists at the Indian Council of Medical Research’s National Institute of Epidemiology (ICMR-NIE) have launched community-based interventions focusing on low sodium salt substitutes. These efforts aim to reduce salt intake and improve cardiovascular health across urban and rural populations.
Excessive Salt Consumption in India
The World Health Organisation recommends less than 5 grams of salt per person daily. However, urban Indians consume about 9.2 grams per day, nearly double the recommended limit. Rural consumption is lower but still exceeds recommendations at 5.6 grams daily. This high intake is linked with increased hypertension and related diseases.
Low Sodium Salt Substitutes
Low sodium salts replace part of sodium chloride with potassium or magnesium salts. These substitutes help reduce blood pressure and improve heart health. Research indicates switching to low sodium salt can lower blood pressure by an average of 7/4 mmHg. This small change has benefits, especially for people with hypertension.
Community-Led Salt Reduction Study
ICMR-NIE has initiated a three-year intervention in Punjab and Telangana. The project evaluates the impact of structured salt reduction counselling delivered by health workers at Health and Wellness Centres. The focus is on reducing sodium intake and blood pressure in hypertensive individuals. The first year involves baseline assessments and co-creating counselling materials with community health workers to ensure relevance and acceptance.
Market Availability and Pricing Challenges
A survey of 300 retail outlets in Chennai showed low availability of low sodium salt. Only 28% of outlets stocked it, with 52% availability in supermarkets but just 4% in small grocery shops. The price of low sodium salt is more than double that of regular iodised salt, averaging Rs 5.6 per 100g compared to Rs 2.7. This gap reflects low demand and awareness, limiting access and use.
Public Awareness Campaigns
To raise awareness, ICMR-NIE launched the #PinchForAChange campaign on social media platforms. The campaign uses infographics and simple messages to educate people about hidden salt sources and promote low sodium alternatives. It aims to empower individuals to make healthier dietary choices and reduce salt intake.
Potential Impact on Public Health
If successful, the project could integrate sustainable dietary counselling into India’s public health system. It may improve health literacy and reduce the burden of hypertension-related diseases. The initiative emphasises collaborative community engagement and systemic change, promoting balanced diets and better heart health.
