Jerry, welcome to raw-food!

I believe this is a myth.  Even prominent vegan proponents such as Dr.
Michael Klaper, MD recommend that vegans supplement with B12 to avoid
running into deficiencies.  The topic of B12 has been discussed a lot on
this list, and if you search through the  archives, you will find lots of
interesting info on the topic.

You are a true inspiration but note that B12 deficiency often takes many
years to develop.
