Do you know how these peanut results compare to the use of olive oil, the monounsaturated oil prominent in the highly regarded "Mediterranean diet"? Years ago some scientists (from Harvard maybe?) argued that the Mediterranean was even better than the then popular extreme low fat diet. And could peanut oil, used in at least Chinese cooking, account for the healthy hearts of traditional-food-eating Asians?
