Colour me confused

So if you keep your eyes open, or set up a feed using Google News Alerts, you come across stuff like this all the time:
President's Choice beef flagged for E. coli. Somewhere, with some meat product, there is always a problem. Yes it happens with vegetables as well - but trust me... it is far more common with meat products.

Similarly, if you keep your eyes open and follow the news... you come across stuff like this all the time:
Being a vegetarian can cut your risk of cancer by a half.

There is always some study saying that a vegetarian diet is healthier than a meat-rich diet. The one I'm linking to here is a brand new study, based on about 61 000 people in Britain, aged between 20 and 90, who were followed for about 12 years. Point being that this is very good and very well executed research.



I've mused about this many times before (most notably here), but what the hell?!! If one diet reduces your risk of serious disease, and the other increases the risk, what in the world would make you choose the bad one!!??

P.S. the pictures are from a story about the Heart Attack Grill in Arizona.

This is the caption under the photo of the pretty waitress holding the hamburger:

The Heart Attack Grill is a hospital-themed restaurant in Chandler, Arizona, which has become famous for embracing and promoting an unhealthy diet of extremely large hamburgers.

That's awesome - honesty from a burger joint. Too bad it is only decorated like a hospital... it should actually be housed within a hospital so that the heart-attack victims don't have as far to travel.
