Great stuff. It can definitely be hard going from a particular ethnic diet to something that restricts entire food groups like PB. I come from a Jewish background. If you reproach bread amongst Jews it's like you're denying god in the holy land. But I'm healthy for the first time in my life so that's what counts.
There is a ton of great info on Mark's blog and other paleo-style blogs that you'll probably stumble upon. Be as a sponge!
