I think I already emailed you about it, but I've received recs in the past for Animal, Vegetable, Miracle by Barbara Kingsolver. It's about her family's decision to relocate across the country to a farm on which the whole family worked to make their own food, or if that wasn't possible, to buy from local farmers. Supposed to be a fascinating and inspirational read.

I have some insight into that sort of thing from my own family's adventure with it in the 70s. I credit my generally strong immune system to that time period's food. It didn't get much healthier than how we ate back then.

Which is why I'm so mad at my mother for letting my young son gorge on pudding once a week at her house. :^/
