What this means for you

A Detox Score of 51 places hijiki seaweed in the Moderate band. The chemical-hazard rating is what drives the score down. Food-safety agencies in several countries advise against eating hijiki specifically, after testing found inorganic arsenic at levels far above other edible seaweeds. This is unusual among sea vegetables — the common alternatives are not implicated.

Cleaner swap → Nori, wakame or kombu, which do not carry the same finding.
