1. The Hook: A Legacy in Your Pocket
Imagine the profound isolation of the wilderness, whether you are traversing the frozen Arctic tundra of the 19th century or orbiting Earth at 17,000 miles per hour. The fundamental challenge of survival remains unchanged across the millennia: How do we carry enough metabolic fuel to stay alive when we are hundreds of miles from the nearest kitchen?
Long before NASA laboratories began engineering rehydratable food pouches, Indigenous North Americans perfected a solution that remains, in many ways, the gold standard of survival science. Known as pemmican, this original superfood was a marvel of pre-industrial engineering.
There is a striking irony in modern science. As humanity prepares for long-duration missions to Mars, many of our most advanced food scientists are attempting to replicate the caloric efficiency, portability, and shelf stability that ancient cultures achieved using little more than sun, stone, and fire.
2. The 5,000-Year-Old Energy Bar
The word pemmican originates from the Cree word pimîhkân, derived from pimî, meaning fat or grease. While widely known by this name, Lakota and Dakota traditions refer to a related food as wasná. In a nuance often lost to history, wasná specifically refers to nutrient-dense marrow fat—the literal lifeblood of the prairie.
Traditional pemmican was a tallow-bound mixture of pulverized protein and dried berries. Producing a single pound of this concentrated fuel required approximately five pounds of fresh meat—typically bison, elk, or moose. The meat was dried until brittle, pounded into a fine powder, and blended with rendered tallow in roughly a one-to-one ratio by weight.
The result was a remarkably durable food that preserved essential nutrients while delivering an enormous caloric punch. Regional variations existed as well. Corn Wasná, for example, substituted meat with toasted cornmeal, demonstrating the adaptability of this ancestral technology.
The numbers behind pemmican remain impressive even today:
- Caloric Density: Approximately 3,500 calories per pound.
- Nutritional Efficiency: One pound can provide nourishment equivalent to roughly four pounds of fresh meat.
- Shelf Life: Often measured in years or even decades when properly prepared and stored.
The legendary explorer Robert Peary recognized its value in his 1917 book Secrets of Polar Travel:
“Too much cannot be said of the importance of pemmican to a polar expedition. It is an absolute sine qua non. Without it a sledge-party cannot compact its supplies within a limit of weight to make a serious polar journey successful.”
Not all pemmican, however, was created equal. Historical records describe “Bovril pemmican,” often used for sled dogs during polar expeditions. It was later discovered to be nutritionally imbalanced, containing too much protein and not enough fat to meet the extreme metabolic demands of working animals.
This early lesson in survival science highlights something remarkable: Indigenous food makers had already perfected the balance that modern researchers would later struggle to understand.
3. The Literal Pemmican War
By the early 1800s, pemmican had become far more than food. It was the strategic currency of the North American fur trade.
French fur traders had long referred to bison as “buffalo,” a linguistic evolution influenced by the French word boeuf (beef). By 1814, buffalo meat—and more specifically pemmican—sat at the center of a growing political and economic crisis.
When the Governor of the Red River Colony issued the Pemmican Proclamation, banning its export, the decision threatened the supply lines of the North West Company. Pemmican was the primary fuel that sustained voyageurs as they transported goods across vast distances.
The resulting tensions escalated rapidly. Economic interests, survival needs, and territorial control collided, culminating in the 1816 Battle of Seven Oaks.
At the heart of this story stood the Métis people. As the primary producers of pemmican, they became indispensable to the fur trade economy. The conflict surrounding pemmican helped shape Métis identity and demonstrated how a seemingly simple food could influence the destiny of entire regions.
In many respects, the Pemmican War proved that calories can be as strategically valuable as currency, weapons, or territory.
4. Why You Can’t Take Traditional Pemmican to the ISS
A voyageur from 1815 would likely recognize modern Saskatchewan pemmican jerky occasionally sent to the International Space Station. However, he would be baffled by the engineering challenges required to make it suitable for orbit.
Traditional pemmican faces three major obstacles in modern spaceflight:
The Danger of Crumbs
In microgravity, crumbs become hazards. Tiny particles can float into sensitive electronics, ventilation systems, or even astronauts’ lungs.
The Rancidity Problem
Traditional tallow is relatively stable, but space agencies require foods that can safely survive extended storage at room temperature. The ISS lacks conventional food refrigeration, making long-term stability essential.
Microbial Safety
Modern food standards demand near-zero risk. Traditional recipes must undergo processes such as freeze-drying, vacuum sealing, and rigorous microbial testing before they can be approved for spaceflight.
The challenge is no longer simply preserving food. It is preserving food in one of the harshest environments humanity has ever entered.
5. The “Burger King” Model of Space Food
As human spaceflight evolves from short-term survival to long-term habitation, nutrition is becoming increasingly personalized.
Scientists have learned that even the most efficient food system fails if astronauts lose interest in eating. Known as menu fatigue, this phenomenon can reduce calorie intake, harm morale, and negatively impact mission performance.
The solution is what some researchers describe as a preference-driven food system—a “have it your way” approach to space nutrition.
Rather than focusing solely on calories, future food programs aim to provide variety, comfort, and cultural familiarity. The Canadian Space Agency has embraced this philosophy by sending regional specialties such as British Columbian seafood and Saskatchewan pemmican jerky to orbit.
These foods do more than nourish the body. They provide a sensory connection to home, helping astronauts maintain psychological well-being during long missions far from Earth.
6. Precision Nutrition: The Final Frontier
The next evolution of the power bar may be something ancient food makers could scarcely imagine: nutrition tailored to the individual.
Through advances in genomics, metabolomics, and microbiome research, scientists are beginning to design diets around each astronaut’s unique biology.
This emerging field, often called Precision Nutrition, seeks to optimize immune function, metabolic efficiency, and overall health during extended missions.
In a fascinating way, this approach echoes an ancient philosophy: food as medicine.
Humanity is moving from the mass-survival model of the fur trade era—where a single 90-pound bag of pemmican could sustain an entire crew—to highly individualized nutritional systems calibrated at the molecular level.
Future Mars missions may depend as much on personalized nutrition as they do on rockets and spacecraft.
7. Conclusion: The Future Is Ancestral
The story of pemmican reveals a profound truth about innovation: sometimes the future looks remarkably like the past.
From meat pounded between stones to vacuum-sealed space rations, the goal has remained the same. Humans seek maximum energy in the smallest package with the longest possible shelf life.
While our tools have evolved from rawhide bags to advanced packaging technologies, the underlying principles have not changed. Modern food science continues to rediscover lessons that Indigenous cultures mastered thousands of years ago.
As humanity reaches toward the stars, we may find that some of our most important solutions are rooted in ancient knowledge.
Final Takeaway
The ultimate survival food was not invented in a laboratory. It was observed, refined, and shared by people who understood the rhythms of the land and the realities of survival.
The future of space exploration is not only scientific.
In many ways, it is ancestral.
