Health writers are sometimes like hyenas...they find something "bad", gang up on and ravage it to death. MD medical writers often go along with mainstream health themes (I suspect because they're popular and safe). More interesting are the papers in magazines like "Science" and "Nature" (where most of the research is published), where health effects are seen to be more subtle (and as writers admit, less understood). Blue Zone studies quite interesting (they come close to showing long-term dietary effects), but otherwise its hard to say how bad chronic "pizza", "doughnut", or "broccoli" eating can be (three surely different outcomes, but how different?)
