I've never understood those who don't eat 'seaweed' on the account of the properties observed at the beach (slimy, salty, sandy, etc). If there is a tuna roll out there wrapped in the same stuff I peel off my leg when I leave the ocean, I've yet to dip it into my soy sauce dish.
Do these same people refuse to eat vegetables on the account of the (literal) crap dumped on it while it grows? Do they throw away the steak when they learn of all the E. coli that lived on it prior to its being cooked?
It must be in the name, the seaweed thing that is. Hot dogs and hamburgers would be far less popular if their names described their origins and I know seaweed suffers here in the USA because we use one English word to describe all the various edible and inedible variations.
