2013.04.03 Eating like a caveman

Written by David Green.


I hadn't thought much recently about the paleodiet, but then I read an article about someone who thinks adherents of the so-called cave man diet might take things a bit too far.

A simple way to look at the paleodiet is to say that if the caveman didn't eat it, then you shouldn't either. Look around your kitchen. Get rid of the loaf of bread. Toss out the boxes of cereals, the crackers, the chips, the bag of rice and the can of beans, the frozen corn, the milk and cheese. And while you're at it, ditch the sugar and the salt. What's left? Plenty, says Dr. Loren Cordain, the self-proclaimed world's leading expert on and founder of the paleo movement. He will sell you some books to prove it. To follow his diet, you must eat:

"the food groups our hunter-gatherer ancestors would have thrived on during the Paleolithic era, the time period from about 2.6 million years ago to the beginning of the agricultural revolution, about 10,000 years ago. These foods include fresh meats (preferably grass-produced or free-ranging beef, pork, lamb, poultry, and game meat, if you can get it), fish, seafood, fresh fruits, vegetables, seeds, nuts, and healthful oils (olive, coconut, avocado, macadamia, walnut and flaxseed)."

Dr. Cordain says research shows that hunter-gatherers were free of the ailments of modern life, from acne to hemorrhoids to cancer. I suppose they died only from attacks by carnivores and other hunters, along with occasional hyperthermia and starvation. But on the bright side, their short lives were free of obesity and gout. They had no near-sightedness and no varicose veins. A pretty good trade-off as they lay shivering in their make-shift shelter.

The caveman lifestyle for modern man apparently goes beyond diet and even includes exercise routines. Cavemen are thought to have run in shorter, intense bursts as they chased down prey or sped away to avoid becoming prey. One adherent put it this way: "Paleolithic exercise is about moving around more, sprinting like your life depends on it every once in a while, and picking up heavy things the way humans actually pick up heavy things, with their whole body."

What I read this morning was an interview with Marlene Zuk, a biologist living in California who has a new book of her own called "Paleofantasy: What Evolution Really Tells Us about Sex, Diet, and How We Live." She says the paleolithic craze is rooted in myth.

Caveman vs. university professor. Sounds like trouble ahead.

Zuk isn't suggesting that there's nothing to learn from studying the health of long-ago cultures, but she thinks it's being taken too far. There was never an era in the past where our evolution caught up with our environment and a golden age was reached, she says.

Zuk believes there are problems trying to replicate the past diet because it varied so much around the world. She says there's even evidence that grains were eaten long before they were cultivated. Besides, all of the food we eat now is genetically different from what was eaten 100,000 years ago.

She knows that many people are happy with their paleo eating, but she's certainly not convinced that it's the answer to all of our current health woes. She says there's evidence showing that paleolithic people suffered from about the same incidence of cancer as modern people, with the exception of lung cancer from tobacco.

Back to Dr. Cordain's website and let's take a look at some recipes. Here's one that requires peaches, lime, onion, green peppers, cilantro and cayenne pepper. Where did Mr. and Mrs. Paleo shop to collect all of that? Another requires salmon, olive oil, romaine lettuce, onion, lemon juice and flaxseed oil. 

Burgundy wine, dark rum, marsala wine, seedless red grapes, cantaloupe, hickory smoke spice, tomato paste, curry powder, lime guacamole, Siracha sauce—I guess I had some misconceptions about cave life. Dinner with Dr. Cordain sounds pretty good, if we can just keep that saber-toothed tiger at bay.

    A PERFORMER named Biligbaatar, a member of the AnDa Union troupe from Inner Mongolia, dances at Stair District Library last week during a visit to the Midwest. The nine-member group blends a variety of traditions from Inner and Outer Mongolia. The music is described as drawing from “all the Mongol tribes that Genghis Khan unified.” The group considers itself music gatherers whose goal is to preserve traditional sounds of Mongolia. Biligbaatar grew up among traditional herders who live in yurts. Additional photos are on the back page of this week’s Observer.

    UMPIRE Thomas Henthorn tosses the bat between team captains Mikayla Price and Chuck Piskoti of Flint’s Lumber City Base Ball Club. Following the 1860 rules, after the bat was grabbed by the captains, captains’ hands advanced to the top of the bat—one hand on top of the other. The captain whose hand ended up on top decided who would bat first. Additional photos of Sunday’s game appear on page 12 of this week’s Observer. The contest was organized in conjunction with Stair District Library’s Hometown Teams exhibit that runs through Nov. 20.

    VALUE OF ATHLETICS—Morenci graduate John Bancroft (center) takes a turn at the microphone during a chat session at the opening of the Hometown Teams exhibit at Stair District Library. Clockwise to his left is John Dillon, Jed Hall, Jim Bauer, Joe Farquhar, George Hollstein, George Vereecke and Mike McDowell. Thomas Henthorn (at the podium) kicked off the conversation. Henthorn, a University of Michigan–Flint professor, will return to Morenci this Sunday to lead a game of vintage base ball at the school softball field.

    HUDSON RUNNER Jacob Morgan looks toward the top of the hill with dismay during the tough finish at Harrison Lake State Park. Fayette runner Jacob Garrow focuses on the summit, also, during the Eagle Invitational cross country run Saturday morning. Continuing rain and drizzle made the course even more challenging. Results of the race are in this week’s Observer.

    Crossing over—Jim Heiney was given a U.S. flag to carry by George Vereecke (behind Jim in the hat), turning him into the leader of the parade. Bridge Walk participants cross over Bean Creek while, in the background, members of the Morenci Legion Riders cross the main traffic bridge on East Street South.

    HOSE safety—The FireCatt hose testing company from Troy put Morenci Fire Department hose to the test Monday morning when Mill Street was closed to traffic. The company also checks nozzles and ladders for wear in an effort to keep fire fighters safe while on calls.
