Healthy Foods, Healthy Diets, and Healthy Eating: Beyond Ethics and Political Philosophy

Healthy Eating Policy and Political Philosophy: A Public Reason Approach by Barnhill and Bonotti is a terrific effort to provide a systematic method for appraising the ethical aspects, broadly understood, of regulations and policies connected to food, diet, and eating. In this commentary I purport to highlight the originality and the merits of the volume by considering what it doesn’t accomplish in three of its parts. I first call attention to the specific construction of the subject matter, namely on the question whether to be at stake are eating behaviors, dietary patterns, or certain food items; while Barnhill and Bonotti do not problematize it, this question is arguably pivotal to design effective policies and to adequately assess them. Second, I discuss the technical concept of “constitutive evaluative standards,” used by Barnhill and Bonotti to lay out their view, as this part of their work calls for an alignment with research on the philosophy of nutritional science and, more generally, philosophy of science. Finally, I take up the technical concept of “accessible reason,” which plays a central role in ascribing the public status to reasons, advocating for a more thorough determination of this concept based on recent work in epistemology.
