Possibly, but generally in my role as librarian I confine myself to doing library work and resist the temptation to offer personal advice. It's true I'm all-wise and all-knowing and if I ran the world life would be grand, but I've made it my policy only to offer advice when asked for it. So I have to satisfy myself with the non-carbohydrate reasons for leaving the food at the library door: the crunching is disturbing the quiet; the crumbs and litter attract vermin; and other people should have a reasonable expectation that papers and books placed on a library table won't come away with smears of nacho flavoring.

But, rest assured, if any patrons should ask me for nutrition advice, I won't miss the chance to proselytize.
