I can't be much help with the cold climate foods (I'm in Vegas, which has its own issues), but I do know most people are fine with coffee. Be aware that caffeine might affect you differently - for me, I used to be super sensitive to it and now I'm not. The beer? That's going to be an issue. It's a grain product and that's kind of the whole point to Primal. From what I understand, the gluten-free beers really suck too.
Lots of people on here don't feel the need to take supplements. Others, like me, take some for a little while until thy feel they've healed and will take a few minerals for life due to specific problems we have. Dirt just isn't as good as it used to be,
My kids are pretty much adults, but there are lots of parents on here. Seems their kids eat what they eat, assuming both parents are Primal. It's the outside people (daycare, grandparents, etc) that are well-meaning, but freaking out about the lack of "healthy whole grains" in the kids' diets.
Glad to see you here!
