Sea salt from clean oceans probably has fewer heavy metals than rock salt, and if cleaned right, it has almost no tiny plastic bits in it.

Microplastics in European sea salts - An example of exposure through consumer choice and of interstudy methodological discrepancies.

Cross-Sectional Study

2023 Apr 15

The study found that sea salt contains microplastics, even after processing, which goes against the idea that it has negligible amounts. It didn’t test for heavy metals or compare pollution levels in different regions.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

Sea salt made the old-fashioned way might have less plastic pollution in it than salt made in big factories — how it's made could affect how much microplastic ends up in it.

Sea salt is cleaner than rock salt because it's filtered through nature and factories, and it doesn’t sit in metal-heavy rocks for ages like mined salt does.

Some of the tiny plastic bits in sea salt might come from how it's made and handled after harvesting, not just from polluted ocean water.

Sea salt might be adding tiny plastic bits to fish that's been salt-cured, because the kinds of plastics in the salt match what we find in the fish.

Sea salt from Europe often has tiny plastic bits in it — on average about 466 pieces per kilo, but it can vary a lot between brands, from as low as 74 to over a thousand pieces per kilo.
