  • This article discusses the World Health Organization's (WHO) recommendation to use lower-sodium salt substitutes (LSSS) to improve public health, particularly in reducing hypertension and related non-communicable diseases (NCDs). Here's a breakdown of the key points:

The Resurgence of Salt in Public Health:

  • Historical Context: The article draws a parallel to the successful iodized salt campaign in the 1950s, highlighting salt as a vehicle for public health improvement.

  • WHO Guidelines: The WHO recommends the use of LSSS, which include potassium chloride and reduce sodium chloride content, to lower sodium intake.

  • Target Audience: The recommendation is for household table salt use by adults (excluding pregnant women, children, and individuals with kidney impairments or conditions affecting potassium excretion). 

  • The WHO also aims to guide policymakers, program managers, health professionals, and other stakeholders.

The Impact of Salt on the Body:

  • Sodium and Water Retention: Sodium causes the body to retain water, increasing blood volume and pressure.

  • Hypertension and Cardiovascular Health: High sodium intake is a major risk factor for hypertension, atherosclerosis (plaque buildup in arteries), heart attacks, and strokes.

  • Vascular Stiffness: Excessive salt consumption can make blood vessels less flexible.

  • Potassium's Role: Potassium helps improve vascular function.

The Global Burden of High Sodium Intake:

  • Mortality Statistics: Globally, 8 million deaths annually are linked to poor diets, with 1.9 million attributed to high sodium intake.

  • Blood Pressure Reduction Studies: Research has shown that reducing salt intake can lower systolic and diastolic blood pressure.

  • WHO Recommendation: The WHO recommends limiting sodium intake to under 2 grams per day.

  • NCDs and Related Risks: High sodium intake is linked to increased risk of NCDs like cardiovascular diseases, chronic kidney disease, and gastric cancer.

Initiatives and Strategies:

  • Sapiens Health Foundation's 'Losalter Group': This initiative aims to raise awareness about the impact of excessive salt consumption and train physicians to educate the public.

  • Call for Multi-Stakeholder Involvement: The article emphasizes the need for public, government, and food industry involvement in reducing salt intake.

  • 'Signal Labeling': The importance of clear food labeling to guide consumers in making healthy choices is highlighted.

  • "Killing Two Birds with One Stone": The initiative is seen as beneficial because it reduces sodium intake while potentially increasing potassium intake, which is often low in many diets.

Challenges and Considerations:

  • Cost of Low-Sodium Salt: LSSS products are currently more expensive than regular salt.

  • Need for Policy Intervention: The article suggests government policies to mandate the use of LSSS and work with the industry to make them more accessible and affordable.

  • Hyperkalemia Risk: The article cautions against increased potassium intake for individuals with kidney disease, highlighting the need for careful monitoring and awareness. 

  • It also mentions the possibility of a large undiagnosed kidney disease population in India.

  • Overall Benefit: Despite the risks for those with kidney issues, the article emphasizes that reducing sodium chloride consumption would be broadly beneficial in India given the high burden of cardiovascular and other NCDs.
