It's still a nonsense idea, and panders to the myth that people from a hundred years ago knew how to do things "right", and we've somehow forgotten. In actuality, food quality now is better than ever before, regardless of the fear mongering. People are healthier, live longer, and are larger of frame because of the better nutrition. In great-grandmother's time things like rickets were much more prevalent than today. Ye Olde Folks got things wrong left, right, and centre, and we get fewer things wrong today. Far better than the throwaway "What Would Granny Do?" is "Understand How Food Works". Not to mention staples of alternative cuisines - for example, my great-grandmother would not recognise tofu as a food, yet would recognise Spam.
