Low-sodium salt does not mean it is devoid of sodium; rather, it reduces the sodium content by 10-30% compared to iodized salt, while incorporating potassium and magnesium sulfate. This helps to balance the body's need for sodium, potassium, and magnesium.
From the composition ratio of low-sodium salt, it is beneficial for patients with hypertension because high sodium is a risk factor for high blood pressure. Reducing sodium content indirectly protects blood vessels, lowering cardiovascular risks.
The British Medical Journal also proposed that if China were to adopt low-sodium salt comprehensively, it could reduce the number of cardiovascular disease patients by 450,000 annually. However, people with impaired kidney function may not be suitable for consuming low-sodium salt.
