Unfortunately this one came out after my pregnancy, so I never bought a copy. But looking at the preview it looks like it has a lot of nutritional information. http://www.amazon.com/The-Everything-Ve ... pd_sim_b_1
That said I think that the one Ariann suggested has most of the info in short version.
I used this book while pregnant. It is an alright book, but I do have to say it's "basic". So if you're a newish vegan, great; if you're an old hat probably not as useful.
I found the info in Vegan for Life to be helpful as well, I refer to it often still.
