Michael Pollan

"Because most of what we’re consuming today is not food, and how we’re consuming it — in the car, in front of the TV, and increasingly alone — is not really eating. Instead of food, we’re consuming “edible foodlike substances” — no longer the products of nature but of food science. Many of them come packaged with health claims that should be our first clue they are anything but healthy. In the so-called Western diet, food has been replaced by nutrients, and common sense by confusion. The result is what Michael Pollan calls the American paradox: The more we worry about nutrition, the less healthy we seem to become.

But if real food — the sort of food our great grandmothers would recognize as food — stands in need of defense, from whom does it need defending? From the food industry on one side and nutritional science on the other. Both stand to gain much from widespread confusion about what to eat, a question that for most of human history people have been able to answer without expert help. Yet the professionalization of eating has failed to make Americans healthier. Thirty years of official nutritional advice has only made us sicker and fatter while ruining countless numbers of meals."

I read this book a few months ago.  I think everyone should read it because it makes you think and makes you realize that in human history 70-100 years of us eating HAS changed.  For the better or the worse? 

The fact that twinkies can remain the same consistency and color for TWO YEARS on the shelf is a bit disturbing.
