If offered at all, use only tiny plain unsalted food-grade seaweed. Avoid seasoned snack packs and beach-collected seaweed. Excess iodine may affect thyroid health, and contaminated beach seaweed can swell in the stomach.
Seaweed includes marine algae such as nori, wakame, kelp, kombu, dulse, and sea lettuce. It provides trace minerals, but iodine and sodium content vary widely by type.
Used in sushi, soups, snacks, and seasoning flakes. Roasted snack packs often add oil, salt, chili, or garlic beyond the plain leaf.
Seaweed salad products typically include sesame oil, vinegar, and sugar. Broth-based seaweed dishes may carry concentrated sodium.
