My friend and former classmate from George Fox Evangelical Seminary published a book entitled, Spiritual Foodways: An Ecofeminist Perspective on Our Sacred Journey with Food. Her publisher page can be found here: http://foodstudies.cgpublisher.com/product/pub.292/prod.3

It's an interesting look at our spiritual connection with what we eat. She says that food should be understood as both "whole and holy." Check it out.
