The soy is one source of carbs - I also like the wasabi. I just checked it out on dietsite.com - 1/4 cup of shredded wasabi root has 8 grams of carbs. Now 1/4 cup of wasabi would probably KILL most people - I use a tablespoon at most and usually less. I'm glad I looked - this is another pretty acceptable food! I'm glad because I stuffed myself on sashimi the other night! YUM!
