What practical method using kombu is suggested to gain minerals while avoiding excessive iodine intake in a single serving?

Using kombu to make dashi broth and then discarding the rehydrated seaweed itself

For high-iodine seaweeds like kombu, a traditional preparation method is cited as a way to balance nutrient extraction with safety. The method involves using the kombu to infuse minerals and flavor into dashi broth. Because the minerals and nutrients leach into the liquid, the consumer receives the benefits infused in the broth. The subsequent step is to discard the rehydrated seaweed material. This approach allows the consumer to benefit from the minerals present in the liquid without ingesting the massive concentration of iodine that remains highly concentrated within the solid seaweed tissue itself.
