Thought of the day

Our direct ancestors--every one of them up the line--managed to stomach their dinner and stay healthy long enough to have children. Most stayed healthy long enough to care for them. Future generations will presumably be able to stay healthy eating today's diet precisely because so many are sick from it in this generation (and perhaps a future "Michael Pollan" will be writing books that advise a return to Big Macs and fries).

Likewise, our sense of taste must also be the result of millions of years of this evolutionary process, always encouraging us to eat such-and-such a food in this-or-that situation. When you really need vitamin C, lemons taste fantastic.

But now it's changed. Modern science has a hundred different ways to create a sour taste, most of them cheaper than lemon juice. I wonder what happens when one drinks a mixture of four or five "all natural food acids", like those in coca-cola, when their body really wanted vitamin C.

And when we need calcium, while our ancestors would have chewed a while longer on that mammoth bone, we grab something else white and crunchy--perhaps a Montery-Jack falvored Cheez-It®. Are we all making (a less severe version of) the same mistake as those poor mulnurished children driven to eat chips of lead paint?

And do we overeat precisely because the statistical relationships between taste and food has been broken? I'm reminded of a line from Fight Club, when Tyler pours lye on Jack's hand:

TYLER:  You can go to the sink and run water over your hand ...
JACK: yes!  yes!  water!
TYLER:  ... or you can use vinegar to neutralize the burn
Anyway, here's a promise to myself--from now on, when I want something sweet, I'll eat a berry or a satsumaimo. If I feel like something crunchy, I'll go for a carrot rather than a potato chip. What on earth have I been doing to myself all these years!

  1. The power to make good food choices. This is the muscle I'm most proud to see you develop!

  2. The flavoring thing is really creepy. It makes me think of Fast Food Nation, where they explain that most of the food flavorings in the U.S. are made along this strip of highway in New Jersey. They can make anything taste like anything. Not dissing NJ, but it just doesn't seem savory.

    Alternately, perhaps the whole of the U.S. will end up living like the blob people in Wall-E, watching personal TV screens, nursing sodas, not interacting with real food or people ever.

  3. Jen, that part of Fast Food Nation is exactly what I had in mind.

    One of the proposed explanations for the apparent failure of fake sugar to affect weight is that perhaps when we eat sweets, our bodies somehow prepare for an onslaught of calories that never come. Perhaps our metabolism rises or we release insulin or some such thing, and then we crash when there are no calories. Maybe that contributes to what's being called "metabolic syndrome" these days. It seems like for all the decades they've been studying this stuff they just don't know all that much about it. It's just so hard to convince people to radically change their diet for any length of time for a science experiement (well, or it takes money, and why would the folks with money want that?).

    Who's to say that there aren't dozens of vital but more obscure feedback loops between our cravings, tastes, and nutritional needs?

    As I write this, I realised the lemon fizzy water I've been drinking at work actually only has "lemon essence and other natural flavours." Argggh! They got me!

  4. I'm with you. This is what I've been telling my mom about her diet drinks habit. Perceiving something as benign (artificial sweeteners) just because it hasn't out right killed people yet seems like like faulty logic to me.

    Sorry about the fizzy water!

  5. Mine eyes have seen the glory of the coming of the cheezit!
