This week's "winner" will certainly be the most controversial yet... bacon!!
There's a lot of bacon consumption in certain parts of the Paleo community. I think part of this stems from a contrarian attitude that comes along with a certain brand of Paleo. Even though fresh meat and moderate saturated fat consumption may be compatible with good health, that doesn't mean it's healthy to eat a cured, calorie-dense food that's essentially been deep fried in its own fat*. I enjoy eating humanely produced bacon from time to time, but I don't make it a habit.
* Some people cook bacon at a low temperature in the oven. This is probably healthier in my opinion, but I still can't view bacon as a health food.
