5 facts for one-day exams
SSC, railway, police and teaching exams ask direct questions like these.
- Potassium-enriched salt replaces sodium chloride with potassium chloride.
- It could prevent 4 lakh deaths annually in India.
- Globally, it could prevent 30 lakh deaths and 1 crore new disease cases per year.
- The study was published in Nature Health journal.
- The WHO recommends low-sodium, potassium-enriched salt alternatives.
Why in the news?
A global study published in Nature Health estimates that replacing common salt with potassium-enriched salt could prevent about 4 lakh deaths each year in India and 30 lakh deaths worldwide. The switch reduces sodium intake and increases potassium, tackling two major causes of high blood pressure, heart disease and kidney disease.
Summary
- Replacing regular salt (sodium chloride) with potassium-enriched salt (potassium chloride) could prevent ~4,00,000 deaths annually in India.
- Globally, the switch could avert 30 lakh deaths and 1 crore new cases of heart and kidney disease each year.
- WHO recommends using low-sodium, potassium-enriched salt alternatives to reduce cardiovascular disease burden.
Highlights
Salt Switch Saves Lives
Replacing sodium chloride with potassium chloride in cooking could prevent 4 lakh deaths in India and 30 lakh globally per year.
Heart & Kidney Disease Reduction
The change could also avert 1 crore new cases of heart and kidney disease worldwide annually.
WHO Endorsement
The WHO recommends low-sodium, potassium-enriched salt alternatives to address high blood pressure.
Background
High dietary sodium and low potassium intake are major causes of hypertension globally. Common salt (sodium chloride) contributes to elevated blood pressure, increasing the risk of cardiovascular diseases and chronic kidney disease. Potassium-enriched salt substitutes replace some sodium with potassium chloride, simultaneously reducing sodium and boosting potassium intake.
Key Analysis and Impact
The Nature Health study analysed data from 193 countries. For India, the potential impact is huge: ~4,00,000 deaths prevented annually. Globally, 30 lakh deaths and 1 crore new disease cases could be averted. Two scenarios were modelled: replacing only household cooking salt could prevent 18.5 lakh global deaths; replacing only packaged/restaurant salt could prevent 15.6 lakh global deaths. The dual action on sodium reduction and potassium increase makes this a cost-effective public health intervention.
Way Forward
Widespread adoption would require regulatory support, public awareness campaigns, and reformulation of packaged foods by the food industry. India's ongoing efforts to reduce salt intake under the National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke (NPCDCS) could incorporate potassium-enriched salt as a key strategy.
Sodium chloride vs Potassium chloride
| Feature | Sodium chloride | Potassium chloride |
|---|---|---|
| Common name | Table salt | Salt substitute |
| Effect on BP | Increases blood pressure | Helps lower blood pressure |
| Health impact of excess | Hypertension, heart disease | Generally safe; excess can affect kidneys |
Background GK
Textbook concepts you need to understand this news
- Sodium Chloride (NaCl)
- Common table salt. High intake is linked to hypertension, heart disease and stroke.
- Potassium Chloride (KCl)
- A salt substitute that tastes similar to NaCl but contains potassium instead of sodium. Helps lower blood pressure.
- Hypertension
- High blood pressure. A major risk factor for cardiovascular diseases, kidney failure and stroke.
- WHO Recommendation on Salt Intake
- WHO recommends adults consume less than 5g of salt per day (about 2g sodium) and use potassium-enriched salt alternatives.

How exams will ask this
- Data: 4 lakh deaths preventable in India; 30 lakh deaths globally; 1 crore new disease cases globally
- Nodal Body: World Health Organization (WHO)
Don't make this mistake!
Trap: Confusing the number of deaths preventable in India (4 lakh) with the global figure (30 lakh). Also, swapping potassium-enriched salt with 'low-sodium salt' or 'iodized salt' – the key is potassium enrichment.

Stuck? Get it in one tap
Common salt contains sodium, which raises blood pressure. Potassium-enriched salt replaces some sodium with potassium, which helps lower blood pressure. A new study says if everyone switched to this salt, 4 lakh deaths in India and 30 lakh worldwide could be prevented each year. The WHO also recommends this switch.
- Potassium-enriched salt replaces sodium chloride with potassium chloride.
- It could prevent 4 lakh deaths annually in India.
- Globally, it could prevent 30 lakh deaths and 1 crore new disease cases per year.
- The study was published in Nature Health journal.
- The WHO recommends low-sodium, potassium-enriched salt alternatives.

Practice questions
Pick an answer, then read the explanation.
- Q1Easy
Which international organisation recommends the use of low-sodium, potassium-enriched salt alternatives?
Explanation: The WHO recommends replacing common salt with low-sodium, potassium-enriched alternatives to reduce hypertension and cardiovascular disease. The World Bank, UNDP and IMF do not issue dietary guidelines.
- Q2Hard
Consider the following statements regarding the potential health impact of replacing common salt with potassium-enriched salt:
- 1.It could prevent about 4 lakh deaths annually in India.
- 2.Globally, it could prevent 30 lakh new cases of heart and kidney disease each year.
- 3.The study was published in the journal Nature Health.
Which of the statements given above is/are correct?
Explanation: Statement 1 is correct: the study estimates ~4,00,000 deaths preventable in India. Statement 2 is incorrect: the global figure for new disease cases prevented is 1 crore, not 30 lakh. Statement 3 is correct: the study was published in Nature Health. Hence option C is correct.
- Q3Medium
According to the Nature Health study, how many deaths could be prevented globally each year by switching to potassium-enriched salt?
Explanation: The study estimates that globally, replacing common salt with potassium-enriched salt could prevent 30 lakh deaths annually. 4 lakh is the India-specific figure. 15.6 lakh and 18.5 lakh are estimates for specific scenarios (packaged/restaurant food and household cooking respectively).
- Q4Medium
What is the primary health benefit of replacing sodium chloride with potassium chloride in salt?
Explanation: High sodium and low potassium are key causes of hypertension. Potassium-enriched salt simultaneously reduces sodium and boosts potassium, helping lower blood pressure and prevent heart and kidney disease. The other options are not the primary benefits of this salt substitution.
