The recent attention to dietary cholesterol, and by extension eggs, has stirred up the customary responses in a world of dietary divisiveness, if not outright dogma. There are rumblings of protest among my many vegan and vegetarian friends and colleagues, who are convinced the Dietary Guidelines Advisory Committee ran amok, whether for reasons of well-intentioned error or something more nefarious. There are comparable rumblings of celebratory validation among advocates of Paleo diets, convinced this committee finally recognized a vintage truth others had neglected. Enough of both protests find their way to my inbox, that it has been a week of unusual seismic activity for me.
I prefer solid ground, frankly, if only to avoid motion sickness. So the fervor for the poles invites a question in the middle: can we say what diet is best for health?
