Ok so strange question, does this have an effect on humans as well? Do regular sushi eaters fart less? (;

The seaweed is a specific kind of red seaweed that isn't used in sushi. The seaweed contains compounds which tamp down specific microbe levels. I doubt the exact same effect is occurring in sushi eaters, though a similar one hypothetically could be.
