Of Dinner and Democracy

In my customary purview- nutrition, public health, disease prevention- I have had cause to lament periodically the apparent hegemony of Newton’s third law. For every silly action we’ve taken over recent decades to address the effects of badly constituted diet on weight and health, we have appended an opposing, but comparably misguided reaction.

In principle, and famously, we had advice some decades ago to reduce our intake of dietary fat. For purposes here, we need not belabor the relevant provisos: the advice originated with studies showing the advantages of the high-fat Mediterranean diet. So, really, it was advice to reduce our intake of saturated fat from the usual sources. The message got mangled as it was passed along, just like in a game of ‘telephone.’ The idea that all dietary fat should be cut, while genuinely favored by some, was actually a distortion of the original mainstream message, but took on a life of its own.

Be that as it may, nobody with any actual expertise- not proponents of eating low fat, and not opponents of eating low fat- ever advocated for low-fat junk food. The original idea was to reduce dietary fat intake by swapping out the salient sources in the prevailing diet- fatty meats, processed meats, processed dairy, fried and fast foods, snack foods- for foods naturally low in fat: vegetables, fruits, whole grains, beans, and lentils, for instance. And, where that was actually done – rates of heart disease and premature death were slashed, and life expectancy extended dramatically. It just hasn’t played out that way in America.

No one worth listening to ever said: just eat Snackwells, and all will be well. But, of course, that- or something much like it- is just what the makers of Snackwells, along with every other version of low-fat junk food, implied. And since they implied it with all of the resources of “Big Food” at their disposal, they implied it to great effect.

How great? Well, intake of all the best, natively low-fat foods changed almost not at all in the U.S. over the past 40 years. For that matter, total dietary fat intake never even went down. Rather, fat only ever went down as a PERCENTAGE of total calories, because total calorie intake has gone up, driven mostly by- you guessed it- low-fat junk, laden with added sugar and refined carbohydrate. Total fat intake, actually has trended up over recent decades, it’s just that total calorie intake has gone up even more. That is the legacy of the “low fat” era in America. As they say in the old country: oy, vay.

Then, to make matters worse, we took the easy way out. We blamed the advice, rather than our monumentally stupid response to it- and surrendered ourselves to Newton’s third law. It was, obviously, time for some equally silly, but opposing reaction, like: cutting carbs. And so we did, bungling it every bit as badly as the “cut fat” message that preceded it.

Nor were those sequential boondoggles enough to cure us of our Newtonian proclivities. We have since welcomed the advent of non-GMO junk; gluten-free junk food; “no longer made with high-fructose corn syrup” junk food; and probably other varieties I’m overlooking.

And that brings us, however tangentially, from the state of our plates, to the state of our Union. For, as opposed to Nate Silver, it may be that Isaac Newton correctly predicted the outcome of this election.

The past eight years represented a remarkably progressive action in American politics. Those personally disappointed, for whatever valid reason, by their trajectory during that span, were presumably invited to express that disappointment with an equal, opposing, and by the reasoning of many of us- regressive- reaction. So here we are.

Whether the topic is the content of plates, or the status of our State, physics itself seems to stipulate that an uninterrupted sequence of forward steps is little less than unnatural.  But equal and opposite need not mean equivalent and self-canceling. When you run, you push against the ground, and the ground pushes back; but the ground stays put, while you move. Progress is possible.

In spite of it all, the objectively measured quality of the typical American diet has improved over recent years, albeit it little, and slowly. But it’s progress just the same, and maybe the only kind the third law allows. And perhaps what’s true of dinner is true of our democracy.

As for Newton, he bequeathed us other gifts too, like calculus. Conjoining that to the third law, I wind up with the calculus of hope. Progress is possible, even likely, but not likely ever to be linear. In accord with the rest of nature, human nature too is disposed to a meandering path of actions and reactions.

Here’s to progress, in all areas, accordingly.
