Throughout my vegan travels, I have been asked many questions about my diet, like where I get certain nutrients from, what I eat, and why i'm vegan. To me it's second nature to know these things, but to someone else, it may need a little more explanation. I have recently come across a great website, http://www.pcrm.org/, which is an organization made of up of doctors and scientists, who help to make sense of a vegan lifestyle to those who are interested in adopting a vegan diet, or even for those who are simply interested in learning more about it. Check out this link: http://pcrm.org/health/veginfo/index.html .
PCRM also does a lot of research on nutrition, and how our diet can actually help to reverse disease, or can help us avoid becoming ill all together. Check out this link for more info: http://pcrm.org/health/prevmed/index.html
I also love PCRM because not only are they determined to end human suffering, they are also committed to end animal suffering as well. They promote alternatives to animal research and animal testing, and also also promote non-animal methods in medical education.
They also have a great recipe archive if you are just starting out and don't know where to start, of if you just want to incorporate a few new veggie recipes into your diet! You can find recipes here: http://pcrm.org/health/recipes/
So if you have questions and are looking for answers, this is a great resource for you to take advantage of!
