Because PDF and Microsoft Word files don’t have consistent formats and are extremely complex so they can't be parsed or easily be turned into a recipe so, no, unfortunately there is no way to import them directly. What you could try however is using the recipe import assistant to import your data. If you can select the text of the PDF files when you select the Text tool in Preview, you should be able to make a MacGourmet Deluxe text clipping of the selected text, which you can then import using the import assistant. You could aslo try using a third party OCR application to export the data.
