When the Hong Kong Consumer Council (HKCC) tested 27 types of ready-to-eat laver (dried seaweed) on the market, the results showed that all samples had high iodine content. Excessive iodine consumption may affect thyroid function.
The tests also found that 70 percent of the laver samples were “high in sodium,” and nearly 40 percent were “high in fat.” The Council worried that people who consumed multiple servings of laver at one time could increase the risk of excessive sodium and fat intake.
