found this interesting site on the philosphy of food.
there's some good reading here if you're interested in this sort of thing.

The role of philosophy is to cut through the morass of contingent facts and conceptual muddle to tackle the most basic questions about food: What is it exactly? How do we know it is safe? What should we eat? How should food be distributed? What is good food? These are simple yet difficult questions because they involve philosophical questions about metaphysics, epistemology, ethics, politics, and aesthetics. Other disciplinary approaches may touch on these questions concerning food but only philosophy addresses them explicitly. Once we have a clear understanding of philosophys unique role, well all be in a better position to engage in dialogue aimed at improving our knowledge, practices, and laws. We should also gain a renewed appreciation for the scope and relevance of the discipline of philosophy itself.
We don't know what our limits are, so to start something with the idea of being limited actually ends up limiting us.
