Hello!

For those interested in the protein, vitamin Bs and other nutrient profiles of seaweeds, read the following book:

"Sea Vegetables  -- Harvesting Guide and Cookbook" by Evelyn McConnaughey.

Published by Naturegraph Publishers Inc.
P.O. Box 1075

ISBN 0-87961-151-0

The author also talks about pollution uptake by sea vegetables.

some sea vegetables have significant quantities of vitamin B12

I recommend this book.
