Well, this is discouraging. An article in Scientific American says that the putative connection between eating vegetables and decreased cancer risk isn't panning out. It points out that the original studies were of weak design, and relied on subjects' memories of what they thought they ate years ago.
Yeah, no kidding that's a weak design. In general, retrospective studies that rely on subjects self-reporting should be taken very skeptically. People mis-remember a lot. (Human memory for detail is just terrible, far worse most people assume.) People lie a lot. And tell the interviewer what they think he wants to hear. A lot.
I swear, I know less every year. Every day brings me new depressing tidings that stuff I thought I knew isn't true at all. The world is an epistemological swamp. Oh, look a rock! Oops, no. Alligator. Never mind.
And the world is chock-a-block with people who, for money, religion, or power, are rarin' to pave that swamp.
