The first time I had to make real decisions for myself was when I started living on my own in my early twenties.
I was aware that there studies on diet and health, and that there were dietary recommendations based on those studies.
I also knew that those recommendations had change over time.
So I decided that I wasn't going to turn my life upside-down over this stuff until the recommendations stopped changing for at least--I picked a number--five years.
Even at the time, I knew that this was mostly a self-serving rationalization for me to just keep eating the foods I liked.
As the years went by, I watched with growing astonishment as the fads (in science!) came and went; diets swirling around them like groupies, or celebrities.
Nothing has ever stayed settled for more than five years in a row.
I've never been called on my original committment/rationalization.
It's been over 30 years now.
