By the middle of Henry VIII's reign, the white meats — that is, dairy products — were considered common fare and people from all classes would eat meat whenever they could get it.Now that is really the "other" white meat! That makes perfect sense. Nutritious dairy put on the same playing ground as meat. They may not have had the chemistry but they didn't need it in this case.
