I liken modern scientists to conquistadors. They have no idea what they're dealing with, but they're going to conquer it, whatever it is --- all in the name of God. Now, don't get me wrong, I'm not opposed to scientific discovery and exploration. I love this stuff. What I despise is reckless disregard for how little we know. We create trans fats with nary a question about whether they're good for us or not. We develop a food pyramid with carbohydrates on the bottom and thirty years later we realize it created an obesity and type 2 diabetes epidemic. It should give us all pause that we would be a much healthier nation if the government had never told us how to eat.
