"...drinking corn with our corn."

"If you wash down your chicken nuggets with almost any soft drink, you are drinking corn with your corn. Since the 1980s almost all sodas and most of the fruit drinks sold in the supermarket are sweetened with something called high-fructose corn syrup" (Pollan Omnivore's Dilemma 11).

"Sweetness is a sign that a food is a rich source of carbohydrate energy. We don't have to be taught to like sweet foods--we are born liking them. A sweet tooth is part of our omnivore's brain. It is an instinct that evolved to help us through times of food shortage. It says: East as much of this sweet high-energy food as you can because you never know when you're going to find some again. This built-in sweet tooth is so strong that we will keep eating sweets even after we are no longer hungry. Our instinct doesn't realize that in modern ties there are always sweet foods available to us. We don't have to go hunting and gathering to get more--all we have to do is walk to the refrigerator" (Pollan 89 Omnivore's Dilemma).
