Completely off the topic of eating (but still in the zone of mindfulness in general), here is a very interesting TED video discussing good stress and how it can improve effectiveness of vaccines, cancer treatments and recovery from surgery.

What I find so interesting about this whole concept is how screwed up research has made us and how it is now it is the job of researchers to validate the common sense approach we were born with.
We know how to listen to our body's hunger and fullness signals when we're born -- we don't over eat.
We know, as young children, that movement is good (and not even purposeful movement -- just movement for movement's sake).
Science can't fix us by itself. Our bodies are wise beyond our conscious mind in taking care of themselves. We just need to listen to what it is telling us and help it do the job it wants to do.
