I can't say it is but, I can't say it's entirely unhealthy. I was looking at my Stockmans handbook this morning in regard to care & feeding of swine. The potatoes would fulfill the energy requirement and chesnuts are a nut which would fulfill the protein requirement.shadowfax said:I read in Larousse Gastronomique (a classic French cooking dictionary) that a pig's diet consisting of potatoes and chestnuts makes a tastier pork. Is this healthy???
