Pillars of Health 2 : Please Keep This in Mind

Before we actually delve into some of the nutrition science, I want to mention something to keep in mind.  We don’t study nutrition issues the same way we study medications.  With medications, we can do a lot to limit the effects of confounding variables so that we can get a good idea about just how effective a medication is.  With diet, it is much harder for a variety of reasons.  Much of the data from dietary studies is self-reported, and that introduces lots of possibility for errors.  The quality of food, even from similar sources, can vary substantially.  How food is prepared can substantially affect the quality of the food, and may be overlooked in studies.  These are just a few sources of potential limiting factors in the study of nutrition, so keep that in mind as you read through these blogs.
