Kim, it has all to do with our genes.
Long ago, we were all "hunter-gethers" and ate just about anything that crawled, swam, flew or ran. (ususally a la raw) All of these critters supplied us a special poly unsaturated fatty acid (PUFAs), just skip the technical and call it a special fat that the body had (and still has) great need of
, ie, prostaglandins, lipoxins, each made of about 20 carbon atoms (to fight infection, inflammation and regulate the major organs of growth, maturity, appitite, fertility, sudden fear (
) vasodilation (blood pressure) and wound healing.
We grew up on tv and radio that sold us on Wheaties, toast, and Tootsie Rolls!
and of course we began to leave these essential fats out of our life.
Sadly, our genes do not have a good messager (mRNA) to tell our DNA how to handle all this sugar and starch so while waiting for few million eons to natually select out genetic structure that effectively works loads of carbs out bodies like good servo-mechanism, stores it in fat around out butts and middle while we get diabetis arthritis, and myriad other unnatural
diseases.
Read Dr. Sears first book and he explains it far better than the vinette above. Basically this is a start. Remember ole St. John-the-Presbyterian (
) lived off locust and honeywhen times got rough!
