This vegan health video is of a presentation Jack Norris did at the San Francisco 2012 Meatout put on by the San Francisco Vegetarian Society. Now that this talk is available to view for free online, all of us folks who were not able to make it to his presentation can benefit from his knowledge and experience -- and learn all sorts of facts and figures from empirical research.
One of the great things about this talk is that he covers expected topics like the importance of B12 supplementation for vegans, but goes quite a bit farther than most of the info you can find online to uncover myths about plant-based diets, as well as tackling some beliefs commonly held by vegans when it comes to what we need and the best places to get it.
Norris refers to empirical and anecdotal evidence throughout the presentation. This inclusion of research and real-world findings to back up everything he does and does not recommend is one of things I really like about this vegan nutrition video.
