Question about nuts

[BetsyB]

Although I am ordering a bunch of raw nuts over the Internet, I am wondering if pecans and walnuts that you can buy in a regular store are "raw". I "know" almonds and cashews aren't, but is heat used to extricate pecans and walnuts?

Also, are packaged dates okay? It does not list any preservatives, etc., but I suspect they are not altogether raw.

Thanks for the input. So much to learn, and I'm having a ball!:D
