Tanuki,

Are you a practicing macrobiotic (whatever that means??). Are you familiar with macrobiotic philosophy?

B12 is indeed a huge topic and one that is often a worry of those eating a vegetarian diet. My understanding is one needs very little B12, but it's crucial to have it. I don't understand your comment that one wouldn't get enough from fish - I think that's quite a generalization and I think each person has to look at their own diet.

For myself, the other options you suggest aren't very appealing. I think there must be choices in the mb field, such as foods which have fermented. I would definitely not go to worrying first, but just to eat a nicely balanced, wide (if healthy) diet.
