News: The WHO has released guidelines recommending low-sodium salt substitutes (LSSS) to improve cardiovascular health.

About WHO’s New Guidelines on Salt Consumption

  • The guidelines suggest reducing sodium chloride (NaCl) in table salt and replacing it with potassium chloride (KCl).
  • The goal is to limit sodium intake to less than 2 grams per day to reduce high blood pressure and cardiovascular diseases (CVDs).
  • The recommendation applies only to household table salt and not to packaged or restaurant foods.
  • Excludes pregnant women, children, and individuals with kidney impairments or those unable to excrete potassium efficiently.

How Excess Salt Affects the Body

  • Sodium retains water in the bloodstream, increasing blood pressure.
  • High salt intake contributes to:
    • Hypertension increases the risk of strokes and heart attacks.
    • Atherosclerosis leads to hardened arteries and restricted blood flow.
    • Vascular stiffness reduces flexibility in blood vessels.
  • Potassium helps counterbalance sodium’s effects and supports better vascular function.
  • Studies show that reducing salt intake:
  • Lowers systolic blood pressure by 4 mmHg and diastolic by 2 mmHg.
  • Reduces risks of CVDs, kidney diseases, and gastric cancer.

Challenges in Adopting Low-Sodium Salt

  • Higher cost compared to regular salt makes LSSS less accessible.
  • Consumer behavior needs to change, requiring government intervention.
  • Government policies should mandate the use of LSSS and promote clear labeling for consumer awareness.

Potential Risks of High Potassium Intake

  • Not everyone can safely consume potassium-enriched salt.
  • Individuals with kidney disease or undiagnosed renal conditions may face hyperkalemia (excess potassium in blood).
  • Health experts emphasize the need for careful implementation to avoid unintended health risks.
