You sound like a person wanting to know some of the alternatives (to mainstream culture).
The big food coop is in Concord. There are health food stores all over - I think you are north of the lake, right?
I'm not aware of any coops up that way, but check out Food Conspiracy in Meredith and Sunflower in Laconia.
I know there are community gardens in Laconia.

Also in Laconia is Sustainable Sustenance - a group focused on food sustainabiilty and Locavore options. I know they have a Facebook Page, not sure about a website (there are two SS on Facebook - chose the non-profit, not the business link).
