So close, yet so far…the Tetons
I’ve recently had the privilege of attending a continuing education conference in Jackson, Wyoming. As a climber who thinks of himself as primarily an alpinist headed to the Tetons, I should have felt like the proverbial cat who ate the canary. Instead, I left my gear in the basement. It wouldn’t have fit in the car with all the ski equipment and clothes anyway (the whole family of four was signed up for the trip). It wouldn’t have done me any good even if it did fit. Four months out of the year, those mountains are shut down due to a horrendous snowpack. When conditions allow, the climbing is still high up and far back.
It turns out that it is almost as hard for a climber to subsist on Teton routes as it is for a cat to live on hunted birds. Signs of compensation for these difficulties were everywhere in Jackson. Right around the corner from the conference center, was a sign for the “Teton Ice Park”. When the first morning of lectures ended, I walked up to take a look. What I saw was the result of a noble effort, but one obviously born of desperation. An enterprising guide service had run a few hoses over a 40 ft. retaining wall to produce about five, moderately-angled chunks of ice. The ice park rented gear, but I decided to utilize a different compensatory facility – the climbing gym just outside of town. It turned out to be quite nice.
Back in the conference center that evening, I was mulling over the dissonance of indoor climbing in the Tetons when the next set of lectures began. Maybe I should have been paying better attention to the speakers. However, it was a series about nutrition, and though the subject is interesting, the hard science behind it could be covered in about fifteen minutes rather than the three hours allotted As I considered my Teton climbing experience, I kept coming back to the viewpoint which kept me in the Black Hills for all these years: alpine climbing is more about training than actually climbing. Adaptation to harder routes in the mountains paradoxically required less time climbing mountains. Living in a place like Jackson resulted in strong legs and weak skills. Unless a climber availed himself of an artificial training facility, the volume of technical climbing needed to improve was just not accessible, at least to anyone with a job. My mind wandered back to the lecturer. He was talking about the Paleo Diet and I found it strangely relevant to the contradictions involved in trying to be a good alpine climber.

This diet is supposed represent our nutritional heritage. It encompasses the type and mix of foodstuffs our hunter-gatherer ancestors adapted to eat. Therefore, runs the logic of the diet’s proponents, it is the mix of foods that we ought to eat to maximize our health and longevity. On the menu is lots of meat and a few plants. Grains and legumes are out. We should eat more like cats than cows, the speaker admonished. To back up his assertion, he flashed a slide on the screen with a picture of a cat at the top and a chart favorably comparing the body compositions of hunter-gatherers with those of cats.
The picture looked a little like my cat, but my cat thrives on dry cat food. I say “thrives”, because I have a dietary comparison-state for her. She was a stray who showed up in our garage when the weather got cold. Before coming to live in our house, she had, in fact, been subsisting on the cat version of the Paleo Diet – fresh, free-range mouse and bird meat. She wasn’t doing so well. She was thin and listless. After a few weeks living inside and dining on kibbles, however, she was tearing around the house like a maniac, destroying rolls of toilet paper and climbing the curtains.
Here are the first four ingredients listed on her cat food label: chicken by-product meal, corn grits, chicken fat, tuna, brewer’s rice. One would expect a wild cat to catch birds, but I doubt one ever took down a tuna, much less an ear of corn or rice. Still, a cat’s ability to live a long and active life eating nothing but rock-hard brown morsels shouldn’t surprise us. Evolution makes the most of things, not necessarily the best of things. Wild cats developed the capacity to survive on mice and birds. Cats are therefore well suited to that diet. That doesn’t mean that there isn’t a diet better suited to cats. Perhaps humans are much the same.
A subsequent slide showed a Kung! tribesman butchering an antelope with a stone tool, and then a chart with cholesterol levels and heart disease rates demonstrating the sterling health of various modern hunter-gatherers. Unfortunately, the health data for the Tarahumara, a group of indigenous people living in Mexico and renowned for their feats of long-distance running, look just as good. The Tarahumara subsist primarily on corn, beans, chiles, and beer.The answer to this dietary conundrum is not found in the diet, but what comes with the diet. Both the Kung! and the Tarahumara are incredibly active, and they do not suffer from surplus. The Paleo diet is not the answer to our health problems. No such simple answer exists.
Of course, there are limits imposed by natural adaptation and on artificial adaptation. Artificial answers are also incomplete. To be a good alpinist, one must climb a certain number of big routes in the mountains. But plate after plate of summits will limit a climber’s potential in the end. Though it isn’t complete in itself, some artifice is required as well. Likewise, when my cat came to live in the house, she didn’t just get dry food, she got a warm, stress-free place to sleep, immunizations, and anti-parasitic medicine. I’m sure she would not be so healthy if we limited our involvement with her to setting out a plate of kibbles on the driveway.
Of the billions of humans alive now, most are suffering from the short-comings of an agricultural, and subsequently an industrial, society and a few are suffering from its excesses. As the most realize the economic, social and technological benefits which drove the move to agriculture in the first place, they no longer get the grace period which the few enjoyed. The harms of excess come right along with the initial development. We can’t simply go back, though. Solutions will require some artifice, and may have an unsatisfying appearance – less like grass-fed beef and more like a bowl of dry cat food or an indoor climbing gym in the Tetons.
