What our research found about seaweed snacks

Roasted seaweed snacks are typically nori sheets brushed with oil and salt. The oil named on the label (avocado, sunflower, sesame or olive) and the sodium are the main differences between brands, along with flavorings such as wasabi, chili or teriyaki. Toppings and crisps add seeds, sugar and other ingredients.

Seaweed is a rich natural source of iodine, according to the NIH Office of Dietary Supplements, and most people in the U.S. already get enough. People managing thyroid conditions should discuss frequent seaweed intake with a clinician.
