I'm talking about a sensible balance, where we eat wisely and healthily, and indulge every now and then, but merely observe our minds a little, catching ourselves when we think negative about what we are eating. The difference is in the mind.
Sooner or later we'll see for ourselves what Penny Sarchet and countless others have uncovered -- that what we take in, what we believe, has a correlation to our health. The days of thinking that the body operates independent of our beliefs about it are fading away.
While some negative outcomes have nothing to do with patient expectations (adverse events are known risks with all treatments), the "nocebo effect" is especially pernicious because it can contaminate good care and is preventable.
