"The Pleasure of Eating" by Wendell Berry
Describes how awareness of the particular circumstances of a food's production can increase the enjoyment of eating. If you know that a food's quality has been optimized and its production has been carefully designed to be most complimentary to the environment, then the pleasure of eating will be that much more enhanced.
Offers some suggestions on how to be more aware and so more appreciative of food. How to have an influence on how food is produced and therefore its quality, the sustainability of the food production system, and environmental impacts of food production.
