Just wanted to share this clip from The Doctors from May of this year that was posted on the Huffington Post. The video discusses common misconceptions people have about veganism and checks in with a couple of people they got to do a 30-day vegan challenge. It's only three minutes long, so they certainly don't go into much detail, but they did talk about how easy it is to get protein because it's in everything we eat (even broccoli!).
They went into pitfalls of a vegan diet as well, including the importance of not just resorting to junk food (bad Lindsay!) and ensuring you get the nutrients you need - especially if you're pregnant. They didn't discuss the nutrients specifically, but vegans need to be sure they're getting enough B12, Calcium, and Iron, just to name a few.
