<p>“Let’s face it, HFCS aside (or not), we eat too much and we move too little and it’s killing us.”</p>
<p>First of all, and this is an aside, there are more corn-based products in food than HFCS. </p>
<p>The big question, however, is why (and all of a sudden) did we end up eating too much? In most cultures, during “down time” (time when less physical energy is expended), folks also downsize their calorie count. It isn’t a conscious process. It just happens. The body sends signals, or more accurately, the brain’s executive function is such that signals between the limbic system and the frontal lobes are such that decisions are made to eat less. When that executive function is disrupted (as it is in alcohol and drug addiction), the brain’s pleasure centers require “feeding”, and often overcome conscious decisionmaking, and feelings of satiety are muted. (There are now good brain imaging studies of “pleasureable eating”, and in many ways they mimic NIDA’s brain images related to drug use.)</p>
<p>It is true that, going from half a pound of HFCS to 72 lbs a year and rising is a caloric boost in and of itself. (Just imagine taking a normal, non HFCS-laden diet, and pouring 4 ounces of Karo syrup over it daily - that’s what the “average” American has in fact done since Archer, Daniels, Midland did its thing.) But, none of this explains why people would “choose” to do so? (and why, when HFCS products invade other cultures, precisely the same thing takes place, and in very short order), and why they would find it so difficult to stop?</p>
<p>Now, mind you, not everyone is obese, and not everyone has a genetic predisposition toward it, and not everyone eats 72 lbs. of HFCS a year (some folks eat much, much more than that.) But we now know that if we want to understand what is going on in so many areas of our life, a good place to start is neurobiology. And to me, it is downright silly to dismiss it cavalierly.</p>
