Of course I listen to McDougallCast. There are some good shows. I love the one where he interviews Jack LaLanne. It's under the "All Podcasts" section, as opposed to the recently added section, and there's a little button near the top that will take you to the rest of the podcasts.
Ditto ^ I really like Vegetarian Food For Thought by Comppassionate Cooks. She's just so awesome, even if she lives in a nice vegan bubble Her advice, stories, and help is much better than anyone's I've encountered ever. I totally adore her!
I think Vegan Freak is just silly. What's up with all the fake-inserted-radio-noises? And yeah, they are very judgemental and come off preachy/ snobby sometimes, IMO.
There's another one I like that's a video podcast about cooking called Delicious TV Vegetarian. It's kinda fun if I have to wait somewhere then I have a cool little show to watch. She has good ideas and reminds me of being in the kitchen with my Mom, if my mom was vegan
