I just discovered this site launched by veganoutreach:http://www.veganhealth.org/
The recommendations they make are the ones I learned about from many of the experts I talked to at a 5 day live in vegetarian convention called Summerfest. These experts included Dr. Michael Klapper, Dr. Michael Greger, and Brenda Davis RD.
The information there applies to vegans as well as vegetarians.
The papers there are brief, informative, have important health information and are easy to read.
