What is the healthiest type of salt to eat?

By The Salt AlmanacUpdated November 8, 20264 sources cited

Short answer

For most people, iodized salt, used sparingly, is the most useful choice because it supplies iodine. No salt is meaningfully healthier because of trace minerals; the amount you eat matters far more than the type. For lower sodium, a potassium-enriched salt substitute is the only option shown in trials to improve health outcomes.

What actually matters

  1. How much: most adults eat well over recommended limits, mostly from processed and restaurant food.
  2. Iodine: iodized salt helps prevent iodine deficiency, especially in pregnancy.
  3. Potassium: potassium-enriched salt substitutes reduce sodium and have been shown to cut strokes, except for people with kidney disease or on certain medicines.

What doesn't matter much

Colour, origin and price. Himalayan, Celtic, black and other specialty salts are mostly sodium chloride. Choose them for flavour and texture, not health.
